greetings
was referred to this forum from someone at androidcommunity.com regarding this...
i searched the forum but couldnt find any relevant posts - can anyone point me in the right direction for doing this properly?
specifically how could one set an image resource based on a string variable being used for part of the image's file name
i tried this based on a post i saw elsewhere:
myContext.getResources().getIdentifier(myStringVariable + "_thumbnail", "drawable", myContext.getPackageName()));
but it returnes a string(or an integer?) of numbers (the resource id?) that setImageResource couldnt use unless i just wasnt doing it properly.
is there perhaps a way to get the resource name based on that id number or whatever it is that im getting?

dang
getIdentifier() returns int and yes, it could be used in setImageResource() method.
But why you want to set resources from strings?
because the image being set is based on user selection and is not just one image its several associated images so there is a number sequence to the image file names as well that i did not show in the snippet i posted.
but i went back and plugged some of those returned values (resources ids?) from getIdentifier() into setImageResource() and it does indeed work so thanks for that - i have an idea what i was doing wrong before but for the sake of moving on im using a different solution now - in short i am now defining each group of images as a separate class member int[] and i will probably use a switch case to plug the correct one into the gridview. its ugly, but i currently only have 11 different groups and no more than 16 images per group so it will work for now until i can study the resource object more and figure out a way to get counts of associated image resources based on a part of the resource name, like with a regular expression or something, because thats the next problem i will have to deal with if i am not pre-defining all of these arrays.
if you know of a way to do that that would be awesome but ill will probably look into it more myself once i get this app closed up and can go back and fix stuff. im pressed for time right now.
thanks
It's really bad thing to use getIdentifier() method, we should always use R class. I think your problem resides somewhere before, you try to do something, that you shouldn't
How do you get these strings? You mentioned they are from user, but he doesn't write them by hand, right? If this is some selectable list, etc., they should be ints, enums, or some objects from the beginning. Not strings. Parsing strings is always ugly.
Ahh and if you have group of many small images, it is usually better to concatenate them into one big image - it's more efficient and you don't have to use 200 R constants in your code.
the string comes from the tag associated with a clickable imageView selected from the previous screen - a menu item if you will. the string will serve several purposes, retrieving related data, etc, but the first thing i needed to work out was retrieving the correct images and displaying them. i dont know how i could concatenate the images into one big image because each one needs to be clickable itself and handle certain events associated with itself.
i will go ahead and admit this is my first app so im basically figuring stuff out as i go. and learning most of my oop from flash has probably handicapped me
i appreciate your help dude

the only other thing i could think of trying was creating an xml doc to group the associated resource names together and figure out how to read from that to know which images to set
i dont see any methods in the R class i could use for sorting, grouping and then retrieving certain resources based on user interaction

Nope
As I said, strings aren't good for identifying things - regardless of the language used. This is why people created int constants and/or enums.
And no, I doubt there are some mechanisms of grouping resources, etc. It must be simple, you are trying to complicate everything
I have a strong feeling that you should change your app architecture and get rid of strings. But here quick general fix (not a good solution! but just works).
Map your strings to R ints:
Code:
Map<String, Integer> map = new HashMap<String, Integer>();
map.put("button_normal", R.drawable.button_normal);
map.put("button_pressed", R.drawable.button_pressed);
// etc
Accessing will be done:
Code:
map.get("button_" + state); // Return int id, use as you need.
This is a bad practice, but it will work. Consider re-archirecturing your app.
@Brut.all: do you have any plans on updating apktool with 2.2 support?
@kadmos
Full example:
Code:
public static enum Planet {
MERCURY(R.string.planet_mercury, R.drawable.planet_mercury),
VENUS(R.string.planet_venus, R.drawable.planet_venus),
EARTH(R.string.planet_earth, R.drawable.planet_earth),
MARS(R.string.planet_mars, R.drawable.planet_mars);
public final int nameResId;
public final int imageResId;
public static Planet findByNameResId(int nameResId) {
for (Planet p : values()) {
if (p.nameResId == nameResId) {
return p;
}
}
return null;
}
private Planet(int nameResId, int imageResId) {
this.nameResId = nameResId;
this.imageResId = imageResId;
}
}
You have enum of planets, each of them has its name and image. Then you could do something like:
Code:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
for (Planet planet : Planet.values()) {
menu.add(0, planet.nameResId, 0, planet.nameResId);
}
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Planet planet = Planet.findByNameResId(item.getItemId());
doSomethingWithPlanetImage(planet.imageResId);
return true;
}
You identifies planets by ints (nameResId in this example - of course it must be unique), not by strings. Operations on ints are several times faster, than on strings, this is why Google decided to identify all things: resources, menu items, etc. just by ints.
Ahh and no, writing switch-cases to do something depending on given object isn't true OOP. OOP is above: enums know, which drawable is connected to them, there is no need for switches.

Yeah, of course, I want to work on apktool this weekend. Unfortunately baksmali doesn't support Froyo yet, so I can't support it fully neither.
@Brut.all:
Ha, I recognise that example It's from the Java Trail/tutorial on enums isn't it? Except they used gravity rather than drawable references.
@kadmos:
Are all the images known from the beginning? In other words, is the user creating them at runtime or are you including them with your app? If they are included with your APK then normally, as Brut said, you should be able to use the identifiers directly.
Concatenating the images all into one isn't hard to do, as you can still draw the specific bitmaps out using the Bitmap.create(bitmapToGetAPartOutOf, ....) method. You can then make those individual bitmaps into ImageViews and only have to remember the 'grid reference' for where they came out of the big image. That said, you'd have to balance the added complexity of creating the big images against the ease of not having loads of R constants. I can't really say anymore because I'm not fully following what you're trying to achieve.

I'm pretty sure I saw this concatenating approach somewhere in official Android's guidelines for performance, but now I can't find it :-/ Also I don't have much experience in Android development, so if no one else suggest this approach, then I think kadmos could forget about it.

i know its not true oop i didnt want to have to do that but i have not yet seen a way to pass any value from a selected item into a method that could use that value to retrieve x amount of associated resources (images in this case).

using the planets example, say i had x (varying) amount of pics of each planet's surface in my drawables and wanted only those planet's pics to display in a grid view when a user selects whichever planet. thats really all this is. being new to this i just dont know the most efficient way to do it. if this was Flash i could just group all the images file names/paths in an external xml doc and use that to load them from whatever folder at runtime - i wouldnt need any of those 200 or so images declared as anything or even as assets in my library (and i would only need the xml because flash cant access a file system on its own to see and filter files that it would or wouldnt need based on, say, a string comparison - though there is third party software like Zinc that gives Flash that capability.)
so i did get this to work by passing a number as a tag (string) in a bundle though an imageView click event and then casting the string as an int to use in the switch - which as of now leads to one of 11 different int arrays of resources names (images) ive got declared in my ImageAdapter class to populate my gridView.
the way i wished i could made this work would have been to use a string (like a planet name) ,passed from whatever planet image/menu item/whatever was clicked, and use that string to compare and determine which and how many images in drawables were associated with that planet and then use that to create my gridView at runtime.

I see what you're saying, that makes sense. Just as a quick note though, if you're declaring your ImageViews programmatically, you don't have to use a string object for the tag. You can directly give the integer and then cast it back when you get the tag. Just remember to use (Integer) as the tag is actually just an unspecified object.

Yes, I can see why you'd want to do it this way. Your current problem is that if you add more images, you have to manually update your arrays. Unfortunately I can't think of a better, 'clean' way of doing it.
@kadmos
Now I have problems understanding you ;-) But if you don't want to declare all images in sources, but in XMLs, then you could use XML arrays.
Code:
<resources>
<string-array name="planet_names">
<item>mercury</item>
<item>venus</item>
<item>earth</item>
<item>mars</item>
</string-array>
<integer-array name="planet_images">
<item>@array/mercury_images</item>
<item>@array/venus_images</item>
<item>@array/earth_images</item>
<item>@array/mars_images</item>
</integer-array>
<integer-array name="mercury_images">
<item>@drawable/mercury_0</item>
<item>@drawable/mercury_1</item>
<item>@drawable/mercury_2</item>
</integer-array>
<integer-array name="venus_images">
<item>@drawable/venus_0</item>
<item>@drawable/venus_1</item>
<item>@drawable/venus_2</item>
</integer-array>
<integer-array name="earth_images">
<item>@drawable/earth_0</item>
<item>@drawable/earth_1</item>
<item>@drawable/earth_2</item>
</integer-array>
<integer-array name="mars_images">
<item>@drawable/mars_0</item>
<item>@drawable/mars_1</item>
<item>@drawable/mars_2</item>
</integer-array>
</resources>
When user will open planet selector, you will iterate through contents of R.array.planet_names array, each item (planet) in this selector will have itemId set to array index. When user will click on something, you will get itemId of clicked item, then you will find array of its images as R.array.planet_images[itemId] (not exactly - it's conceptual example).
You will be able to add new images or even planets through XML editing.

as i posted earlier this was the idea that i had - i havent tried it yet because i wanted to get some feedback from you guys just to see if i was completely off base. so right now its coming down to what would make for the more memory efficient final product - declaring all these images as class array constants (which i already have working) or using xml and coding the operations for parsing, counting, filtering, assigning, etc?
again thank you guys for your time and help

Do you mean parsing XMLs? My example above uses standard Android resources. You don't have to parse these XMLs, you will get them as arrays And yes, it's super efficient, because they are compiled to easy-to-read form
ok then im going to go ahead and try it
be back soon

Hi all,
I'm new to Android development, kind of a Java noob, but not to programming in general. I'm not looking for code examples, just theory or a basic 'how this is done' in Java/Android. I also hope this will become useful information for other developers heading down this path.
I've had some success creating my first Android app - I apologize for not going into details about the specifics of the app, as I plan to eventually sell it commercially on the market - the question should, however, be applicable to any application using this flow model.
My current goal for this application is to create a 'plugin' type system ( like those used in OpenHome and other apps that allow user-generated plugin-able content / functionality ), to allow for flexibility in both my own further component development, as well as eventually creating an open interface for other developers to use to extend the application.
Currently my application is laid out as follows:
Main UI class
- entry point to the application
- starts the service class to spawn 'spinners' ( data processors )
- presents the user with an (ideally) extendable interface to the service
- binds to the service class using AIDL
Service class
- presents an AIDL interface for communication from the UI process
- creates 'spinners' of various types based on user interaction that process data
- persistent, will run in background, new Main UI instances will connect to the running service and present the currently running spinners.
- extendable via an as-yet-unimplemented plugin interface to add new types of spinners
Spinner classes
- use a generic interface with a handfull of common methods to communicate with the Service class, bubbling up data to the UI interface.
- processes user defined data streams, outputs to a buffer/sink suppled by the Service
Assumptions I can make are:
- the plugin (Spinner) class will always implement / override a group of methods to present to the Service class; ie 'putData()', 'getStatus()', 'start()' and 'exit()'
- the plugin class should always return data to the Service class via a supplied/shared buffer ( short array, for example )
Where I'm stuck at the moment is exactly how to implement extendable classes without those classes being a part of the current code base package. More simply, how do I interface with these classes without knowing their names, methods, etc?
As mentioned, I'm new to Java so I may just be overlooking an already implemented class that handles this interaction. If that is the case, I'd be happy for anyone to tell me to shut up and read the docs, if you can point me at the proper docs
What I really don't want to do is create a 'plugin language' for these external bits, as I feel this could hamper development of fast/functional plugins vs. those written as native Java classes. This would also expose potential security issues, as I'd need to create a public interface to the Service class for these applications to link to. I'd prefer if execution of the plugins remained private / internal to the 'main' application.
I'm already using an AIDL interface between the UI class and the Service class - it would potentially be possible to use further AIDL interfaces into each plugin, but from my romp-through-the-park implementing the UI -> Server communication in this way, I find it cumbersome and difficult to pass any kind of complex data sets/controls. And I'm still unsure how the Service class would actually implement these without inheriting the interface directly.
I've poked around Intents in Android, but I'm having trouble wrapping my head around them/what they're for - it seems it might be possible to inherit the plugins that define themselves as sinks for my applications specific Intent type, but I'm lost in the details of how this works exactly, or if it would even be a viable path for what I'm trying to do. Can new Intents even be introduced into Android?
I apologize for the long-winded explanation of what boils down to a simple question:
How can I implement a 'plugin' interface in my application to allow myself and other developers to extend my app through their own classes?
I've been a Java developer for 10 years or so.
From what I understand the "Android" way, would be intents. I'm still working on wrapping my brain around them too.
However, the "Java" way would be to define an interface (or several) for the plug-in(s) to implement. Then use reflection to identify classes in the classpath that implement that interface.
There are some advanced techniques using custom class-loaders, but researching reflection should get you started; if you choose to go that route.
Thanks for the quick response, I'll take a look at the reflection implementation.
Intents do seem to be the 'way to go' for inter-application communication in Android the more I read about it though - if I can figure out how to pull in plugins which specify my applications 'Intent' dynamically. Intents seem to work really well for spawning a 'dumb instance' of an application - like the browser when clicking a link in another app - when your application doesn't want to deal with that data locally.
Seems a bit more difficult to wrap them around a bi-directional interface between the service and the external plugin application. If anyone's got experience with this kind of thing I'd definitely appreciate prodding in the right direction. Documentation on Intents is confusing at best.
Storing objects to a Database for an Android application should be fast and easy as:
Code:
dm.add(new StorableClass());
DataManagement is a new open source library that allows you to do just that.
DataManagement is a Java Android library designed to help easily and efficiently store aggregate classes to an SQLite database. It eliminates the need to write separate classes to manage database – object interactions and allows developers to use simple methods to store, query, update, and delete objects. The library is capable of storing all objects of classes whose instance variables are either primitive data types or are themselves objects of another storable class. The DataManagement Library condenses many standard database features into several simple methods. It is fully open source and the code can be found at http://epsilonlabsllc.github.com/DataManagement
Examples:
Creating a Storable Class:
Code:
public class StorableClass{
@Id
private int ident;
private int num1;
private double num2;
private String num3;
private boolean num4;
public static final int num5 = 3;
private OtherStorableClass[] ds2;
}
A storable class must meet two requirements. First, the class must have a private instance variable of type int that will be used as the id number of the object. This variable may be read by the application, but the application should not have the capability to write to or change this variable in anyway. This variable is identified by the system with an @Id annotation. In addition, the class should not have any instance variables that are not either primitive types, strings, or other storable objects.
Instantiating a DataManager Object:
Code:
DataManager dm = new DataManager(context);
The open method accepts the calling Context that is going to use the database. Usually this should be the calling Activity.
Opening a Database for Use:
Code:
dm.open();
This method must be called before the database is used in any way.
Closing a Database After Use:
Code:
dm.close();
This method should be called after all database operations have been performed.
Adding an Object to the Database:
Code:
int id = dm.add(new StorableClass());
The add method accepts an object of a storable class as its only parameter and adds it to the database. It returns its id in the database for future use.
Retrieving a Specific Item from the Database by ID:
Code:
StorableClass storableObject = dm.get(StorableClass.class, id);
The get method accepts two parameters: the data type of the stored object and the Id number of the object (the return value of the add method).
Retrieving All Objects of a Given Type Stored in the Database as a Collection:
Code:
storableObjectCollection = dm.getAll(StorableClass.class);
The getAll method’s only parameter is the class of the objects that should be retrieved.
Retrieving a Collection of Storable Objects that match a given criteria:
Code:
Collection<StorableClass> storableObjectCollection = dm.find(StorableClass.class, 5, "num1");
The find method accepts three parameters: the data type of the stored object, the value that is being searched for, and the name of the instance variable as a string. This method is overloaded in such a way that the second parameter may be any primitive value or a string.
Updating an Object in the Database:
Code:
dm.update(id, updatedObject);
The update method accepts two parameters: The id number of the object being updated and the updated object that will replace the existing one I the database. If the id number of the new object and the id number given as the first parameter do not match, the object’s id will be overwritten.
Deleting an Object by its Id number:
Code:
dm.delete(StorableClass.class, id);
The delete method accepts two parameters: The data type and id number of the object to be deleted.
Additional Notes:
Id numbers are used by the database to ensure that objects are put in the correct place and to allow the program to access these objects. It is important that programs using this library do not attempt to set these variables as they will be initialized and managed by the library. These id numbers are unique for objects of a given type; objects of different types may have the same id number. In addition, if objects are deleted from the database their id numbers are left empty and are not reused.
Licensing:
DataManagement is Currently Licensed under the GNU General Public License, version 3 (GPL-3.0). It is intended for open source use by anyone who would like to use it.
This is awesome!!
Tried it out for an app today-- incredibly simple! For those looking-- this library essentially replaces loads of SQL helper classes and queries with an interface that's similar to ArrayList.
Definitely going to use this for everything in the future!
Thanks
Did you change the license or something? The repo is no longer on github.

Hello,
I'm trying to build a simple project the test and learn how this lib works, but I'me quite new in programming and I have some difficulties to understand how to use dm.
The project will be a simple song database with edittexts for song and artist. I created the storableClass as the example, but I cannot understand how to connect it with the main activity, so I can use the output of the editTexts.
1st question is: do I need to have the String variables as private? I'm thinking that must have them as public, so I can connect them with the editTexts output.
2nd: question: all these methods needed to be called from storableClass, or from main activity, after I connected the storableClass with main activity? And how I do this?
Probably with the use of context you descibed, but I cannot understand how to do it. I tried sometimes but always get errors and a specific one "The constructor DataManager(Context) is not visible".
Is there any example project' source code which use this lib to get an Idea, or can you explain the context step more extensively?
Thanks in advance and sorry for noob questions.

Here is a sample project: https://github.com/epsilonlabsllc/D.../net/epsilonlabs/datamanagementefficient/test
(It's in the github project.)
You can set the strings on private, because you can grab the values of the edittext on your layout. Eclipse should generate your set/ get methods if you create your private strings. The methods. Take the values and insert them into your db, Look at the sample:
Code:
public DataSample(){
num1 = 3;
numderp = 3.0;
num3 = "three";
num4 = true;
ds2depier = new ArrayList<DataSample2>();
ds2depier.add(new DataSample2());
ds2depier.add(new DataSample2());
}
That is the basic constructor of the DataSample class. If you do an insert like
int id = dm.add(new StorableClass());
Click to expand...
Click to collapse
The basic constructor will be called and it sets your values for example the num1 =3. You could overwrite the basic constructor with your costum constructor to insert your values.
You activity call:
dm.add(DataSample(sSong,sTitle));
Click to expand...
Click to collapse
The constructor could be something like this:
public DataSample(String sSong, String sTitle){
sYourTitleDataBaseColumnCaption = sTitle;
sYourSongDataBaseColumnCaption = sSong;
}
Click to expand...
Click to collapse
Or use the set/get methods, my custom constructor are just an idea to show you an example. Just take a closer look at the github sample and it should work for you.
Thanks, I think I can figure it out now.
How to is very outdated. I can't initialize via new DataManager() but via getInstance(), also delete and update method doesn't have Id argument anymore.
Also,
I can't get this to work. I can't even add a member to collection because it needs to use db.add(new MyClass()); but i already have MyClass() initialized with their members. I have tried to do something like copy the Id from add, update into my other instance of this class and run a db.update() but it throws a RuntimeException.
Not usable at this time.
Sounds good!
I'll give it a try as soon as I start a new project that requires data storage ...
I really hate SQLiteOpenHelper, cursor and all this strange syntax ...
The idea is good, but it can't be compared to db4o, specially when talking about documentation.
Hello mate,
I'd like to use your library and backup the data with Google/Dropbox Sync... can you tell me the name of the file on which you save data?
Thanks,

This is a very simple application that enables you to specify any kind of Uri to launch. This is done through creating a Toast notification that, when clicked on, will execute the specified Uri. This uses a native method outside of the regular SDK; the standard methods available in the SDK that you'd normally use to create a Toast notification are restrictive in what kind of Uri you can specify. By using the native method not part of the SDK, these limitations can be by-passed.
I've attached both the XAP and the source code. The source project contains three projects:
CShellChromeAPI: The C++/CLI project which calls the native un-documented method
NativeToastLauncher: The .NET wrapper which simplifies the interaction with the C++/CLI project
NativeToastLauncherApp: The test application used to quickly launch any Uri
You'll notice I've hard-coded a default Uri when you launch the application: this will open the Windows Phone 8 "About" page.
To run this, you'll need to side load the XAP which requires a dev unlocked device...

Any registered app GUID yes. You'd do app://GUID/_default (or replace the _default with the particular task to run - in most cases, that's _default).
@cpuguy this is awesome, thanks!
If you guys are looking for GUIDS and default tasks, they are all in the app's WMAppMAnifest.xml. the "ProductID" is the GUID and the "DefaultTask Name" property contains the name of the default task.
Hopefully we can use this to find a program to exploit.

If you download the registry hives located at http://forum.xda-developers.com/showthread.php?t=2393883 , you can load the Software hvie and search for "app://" That will give you a few system files you can launch.
EDIT:
I posted a zip file of the default ones in a new thread.
IF anyone has tethering blocked, see if you can get it to work by launching this URI app://5B04B775-356B-4AA0-AAF8-6491FFEA5629/Default

Im only seeing the app:// function used on the system settings options after going through the regsistries so far.

that's what I saw too. I am having way more luck finding cool stuff in the extracted ffu. Take a look at the zip file in the new thread I started.

yea, I saw the new thread. Hopefully somebody can find a exploit in all that. It executes some cool files. Too bad there wasn't a cmd.exe file on our phones that we can execute.

actually..there is! but it's stuck in a WIM. It inflates it on an "as-needed" basis.
I am hoping that we can use the backgroundworker to run some stuff elevated

But they all are pretty much isolated. It is unlikely that you will be able to run anything elevated

Not only is there a CMD.exe, but there are other interesting things like a BSOD screen, Control Panel, registry keys referencing desktop (A future exploit I might attempt), and even native EXEs (We knew about native EXEs since WPs release).
Why does this launcher not work with "normal" toasts: {YOUR-APP-GUID} and "/Page1.xaml"? Only with empty GUID and full path.
Similarly, any chance this could be used to open arbitrary XAML pages, rather than just the ones defined in the app manifest? For example, something like what was posted in another thread (http://forum.xda-developers.com/showpost.php?p=45265419&postcount=56) using the following URI: app://5edbdbbc-2ab2-df11-8a2f-00237de2db9e/_default#/View/APNSettingPage.xaml to launch a hidden page in the Connection Setup app. I don't know if that's a weird behavior of CS or if its universally possible (and while it feels lazy to ask, I'm at work right now). There are a bunch of "hidden" pages in the ATIV S Diagnosis app, some of which would be very useful, but the navigation code for them is blocked or outright missing. If we could invoke those directly... There are probably a bunch of other such hidden gems in other OEM apps too.
Yes you can. The way I found the one in the HTC app was by loading the dlls in JetBrain's dotPeek. Then I looked for the xaml files. It is all a relative URI based on what dotPeek/the app "sees". The only thing the manifest states is where the default entry point is for the page. Basically I looked in the manifest file for how it calls the "default" page. and then replace it with the relative URI for the other page you want.
If you guys want, I can write up a simple tutorial. I just have an HTC 8x, so my hands are tied. If someone can figure out how to deflate an nbh file so I can browse it, that'd be fantastic! I found a "dead" 521 on eBay that I am thinking of picking up for research since there are way more tools for Nokia.

That's correct. I have been navigating to various - normally unreachable - XAML pages in quite a few of the Nokia apps. I gave an example of that in a different thread:
Code:
app://[COLOR="Navy"][B]2377fe1b-c10f-47da-92f3-fc517345a3c0[/B][/COLOR]/[COLOR="Orange"][B]_default[/B][/COLOR]#/[COLOR="Green"][B]Launcher[/B][/COLOR];component/[COLOR="DarkRed"][B]MainPage.xaml[/B][/COLOR]
In this example, I launch the Nokia extras+info app (2377fe1b-c10f-47da-92f3-fc517345a3c0) with the default entry point (_default) which, as @compu829 stated, can found in the app's manifest. Following that, you can add "#/" (not sure if either the hash-tag or slash can be taken out or both are required to work but I know with both, it does work) to the URI to specify a particular XAML file you'd like to open. Following the "#/", you get to specify the assembly (i.e. the .DLL in the XAP file) in which the XAML file is located (Launcher). And finally, you add ";component/" followed by the full path to the XAML as defined in the embedded resource file (MainPage.xaml).

I presume your reference to the "empty GUID" is for the first parameter of my static Launcher.LaunchToast method? That first parameter is, as far as I can see, ignored for the actual toast launch. If I'd have the signature of the "Shell_PostMessageToast" method, I could perhaps understand what it does but, without it, I just knew it wanted a GUID (passed to it as a string) and that that GUID could be an empty one. I reversed engineered the signature from that native method (found in ShellChromeAPI.dll) by taking a look at another native assembly calling it. Naturally, this only tells shows me how that method is being called but doesn't return the name of the parameters. If I remember correctly, the assembly calling that method was passing its own application GUID... I could have done the same but, I didn't see what use it had so I decided to keep passing it an empty GUID.
The format of the toast is different most likely because that's the raw toast launching method. The other format you're used to is the more developer friendly one that's sanitized prior to launching it (so you can't launch another app directly).
Success!
@GoodDayToDie , this is exactly what I'm trying to do! And here is result:
I am making an app where it does the following:
1. User opens adobe on andriod phone and makes some comments to the pdf then click the share button. It opens a list of apps and user picks my app
2. The file is opened in my program (at least in the background) and it saves to my remote server (I will use PHP on my server to accept the file...Just need java code)
I have part one nailed. I can't get part two
This is an internal app so I can ensure all my team has adobe. Every single example I see is for images..... I am brand new at java
Code:
static final int REQUEST_FLAGES = 1;
final Intent intent = new Intent(Intent.ACTION_CREATE_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("pdf/plain");
intent.putExtra(Intent.EXTRA_TITLE, "tonypdf.pdf");
startActivityForResult(intent, REQUEST_FLAGES);
It saves the file, but then the PDF file is empty......I can't figure out how to put the data into the PDF file:crying:

If you can get the path to the PDF file being shared, this answer on StackOverflow is pretty good for uploading to your server.
http://stackoverflow.com/questions/...e-in-android-from-mobile-to-server-using-http
Sorry if this is skipping a step and not really answering your question, but you may be able to approach it differently than using the Share action.
P.S. I think your problem is that there should be a "Body" added to the Intent's Extra data:
intent.putExtra(Intent.EXTRA_BODY, "<body of PDF somehow>");
Sorry, I have never dealt with PDF files :/
