Parsing serial data over bluetooth - Arduino to Android - Java for Android App Development

Hello,
I have been transmitting values from my Arduino to my Android using the BlueSerial app. It's great so far, however, I'm only able to read values. Ideally, I want to read these values displayed, and convert them to a variable so I can use them for calculations. I have not altered the Blue Serial app, and the code can be found here (I'm unable to post links due to being a new member): github*com/plastygrove/BlueSerial
As I said, I would like to convert the strings to something useful in order to do calculations. Can anyone provide some guidance?
Thanks.

Isn't it easy enough to make Integer.parseInt(receivedMessageString); ??

Yeah! Actually, I managed to use that and got it working. But now I want to transmit multiple values and store them as a variable. How can I go about doing that? Over serial, I can transmit them any way (whichever way is easiest), such as:
HTML:
Voltage = 25
Current = 10
Speed = 5
Or without text if necessary like:
HTML:
25
10
5
Or on a line separated by commas, such as:
HTML:
25,10,5
How can I make my android app "know" that there are three separate values being sent, and store each of these into a variable?

Maybe send string values like 'speed: 25', then extract integer from string and turn into value? That's just first idea that came to my mind. What kind of device are you reading from?

That's actually what I managed to do. I used integer.parseint() for the one value. However, wouldn't this change when I'm sending more than one value? I'm trying to figure out how I can individually read each of the three values and store them. The integer.parseint() is working for the one so far though, so that's a start.
I'm sending data from my Arduino Mega to a self-made Android App via bluetooth. The data sends perfectly. And using integer.parseint(), I was able to even do calculations with the incoming number. But when I try to transmit several values, it gets tricky.

Maybe a HashMap <String, Integer> could work?

converting ASCII to Unicode

hi ther i wonder if you could help me on this simple task. I'm creating a GPS application to run on the XDA2, i'm using eVC++ to do the implementation.
at the moment i'm reading the GPS signal via bluetooth over a virtual COM port, the signal coming from the GPS if a ASCII sinal and i'm duimping this into a char buffer.
However i need to convert this to UNICODE in order to display it on the Pocket PC, how's best to convert a buffer full of ASCII into Unicode so i may display it?
I tried using MultiByteToWideChar(), but it doesn't seem to work properly, maybe i haven't set it up correctly? Could someone point me in the right direction!
Below is an example of what i tried:
Code:
char buf[50]; // contains output from GPS
TCHAR Message[50]; //where i intended to put the message so i could display it
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, buf, -1, Message, 0);
Thank in advance
I'm sure it's not the right way to go about it, but I generally wsprintf for short strings.
However, don't listen to me, I'm a mad man. Check this page out instead:
http://www.i18nguy.com/unicode/c-unicode.html
V
Thanks for that, out of curiosity, how would you use wsprintf to convert ASCII to unicode, i tried that before with no real success!
The last value passed to MultiByteToWideChar tells this function the size of the result buffer, Message in your case. You have passed zero, all that does is makes the function return the size of a TCHAR variable it needs to put the Ascii input buf into.
You need to put sizeof(Message) as the last parameter and not zero.
The other way (better way ?) of doing this is first you call the MultiByteToWideChar function with the zero parameter as you have and then you malloc the result * sizeof(TCHAR).
Thanks for the advise, after looking into the function more i realised this is where i was going wrong, and i have now managed to make the conversion. Thanks for pointing that out though!

Cell id Command line

Hi All,
Is there a tool which can get Cell id and LAC from command line for it to be used by other apps
Say I have script (mortscript)
Then I can call <Cellid APP> and get Cellid location where the device is
Then take action based on the Cell id.
Idea is to track the phone and let the owner know where all the phone on a web page.
I go from HOME -> LOC1 -> LOC2 ->Office (everyday)
Incase phone shows a path HOME -> LOC1 -> LOCX -> <UNKNOWN> .. the send a TEXT(SMS)/update page etc ... to alert the users.
Kind of way to make your phone secure.
Any suggestion if it can be done with any exiting tools and mortscript etc ...
http://www.xs4all.nl/~itsme/projects/xda/tools.html
has something called riltest ...
riltest - dumps all kinds of info from the phone via ril
But the zip files does not have this file... Could any one let me know if this file is available any where else.
Ok Got a riltest from Another forum which does similar ... ALMOST....
what it can do is dump all to a LOG file ... I am using a Mortscript
1. Run the app
2. make app to dump logs
3. get the details from the file.
4. close the app.
Now loop this for with a sleep ...
But still looking for better way.. Attached is the file for anyone who is looking for similar stuff.
Hi,
I too was looking for something in this line and ended up writing it myself.
Props to this chap for the code to get me started:
http://dalelane.co.uk/blog/?p=241
Basically you call 'RilCmdLine.exe' with a parameter indicating what field you want. It returns the field as an int to MortScript (I think you need MortScript 4.3b1 or above?).
Supports LAC, Country Code and Cell Tower ID.
The zip includes a test mortscript - you may just need to edit the path to RilCmdLine.exe
(Source code on request. I may even support it )
Hope this helps!

Hi
Thanks for the exe file. However I am unable to see any result when I run the exe/mscr on my mobile (HTC 3300 WM6). I did edit the path also executed from cmd line on mobile.
Also Mortscript RunWait and Run will not return any results as per the Mortscript doc. So the result has to be redirected to a file.
Could you please check and let me know if the exe is required to be executed with different parameters.
Thanks
What version of Mortscript are you running?
I had to upgrade to 4.3b2 to get the return code from the exe.
Get it here
http://www.sto-helit.de/index.php?module=download&action=view&entry=125
In the notes for b1 mentioned the return code functionality being added.
Hope this sorts it for you
Perfect !! Thats works perfectly ... I updated to MortScript you have suggested.
Excellent Work !! ... Really good. Thanks man
Will it be possible that if I don't pass any Command line parameter ... Can I get all the values... Like CELL ID, LAC etc ..
Glad you like it
Unfortunately you can get all the values at once (at the minute you can only return numbers from the exe, so there is no way to separate them).
My original idea is something along what you suggest - if I get that working I will post a new exe up here.
Thanks
Thanks onionfx! This is just what I was looking for as well. Trying to do something similar to what wishme said. ;-) The common profile switchers out there are not very useful to me because I'm more of in a rural area, and cell towers are farther apart, so my home and work cellid overlap sometimes, so I want to also take into account signal strength to see if I can fine tune it better. Will probably use Mortscript since it's the only thing I've learnt to code with for Windows Mobile.
I'm bookmarking this page to see if you eventually get the prog to output all in one line (and reduce the CPU churn of calling the same prog several times).
BTW, how about also returning nearby cells in order of signal strength? That would be awesome to fine-tune your location even more!
Good work!
Cesar
Doing some thinking about this
I can't see any way of returning all the values at once.
The C code can only return an int in the range -2,147,483,648 to 2,147,483,647 and my CellID and LAC are 5 digits each so if they ever started with a digit greater than 2 I couldn't return it.
The 2 best options I think are writing another exe that dumps the data either to a file, or to the registry in a similar way as riltest above, but without the UI part.
Then write a script that could be included, and which has nice subs to access each parameter (or you are free to write your own script calls to do this).
I'm tending to the file as I imagine reading from the registry is a bit slower than reading the file (in one go and storing all the params as variables)?
Also I can do less damage if I use a dedicated file!
Anybody got any better ideas, or has a good reason to use the registry?
Goodnight
Are we talking about GSM signal strength
REGISTRY entry: HKLM\System\State\Phone\Signal Strength (DWORD value)
More here: http://wiki.modaco.com/index.php/Windows_Mobile_5_Registry_Tweaks
Also is it possible to get all other the cellids at any point not the one phone is connected to ? I have not see any app providing this info.
Except for Google maps on mobile (without GPS) it uses triangulation technique to get the Latitude and longitude of a location with all cell id locations available. for this method to work we requires atleast 3 cell id.
Does RILCELLTOWERINFO gives details about other towers also ?
I wonder what the requirements are for the command line tool?
It locks up when I run it on my MotoQ smartphone.

I can't get this to work. I get "-1" for all 3 values. Anyone offer any reasoning as to why this may be? I believe my ROM includes .Net framwork, but I'm not sure how to check.

[App][Apr 24 2010] PlaySound - Command line sound player / vibrate for scripting

Description
I had a need to play a sound and vibrate my phone in a script-like setting (specifically, actions in the amazing Rhodium Keyboard Controller app). I couldn't find a simple app to let me do this. So I wrote one! It took about 10 minutes. I now share this with you because I'm sure somebody else has had the same need.
Tip Jar
Like this app? Want more like it? Tip a buck (or Euro or Pound or whatever) or two to help the author out! Click here to make a safe donation via PayPal.
To Use
1. Copy the PlaySound.exe file somewhere, like \Windows.
2. In your script or LNK, use command line arguments to tell it what to do. A single command line argument means that you are specifying a path to a sound to play. It will only play WAV files (sorry if you want WMA or MP3 etc you will need to convert). If you specify two arguments, it means you want to vibrate the phone. The first argument is the LED index of the vibrate (usually 1), and the second is length of time to vibrate in milliseconds.
3. If you do not specify command line arguments, or specify invalid ones (wrong path, negative number, etc.), it will fail without any notice (run, then immediately quit). This app will not tell you when something goes wrong.
Examples
Play the loudest.wav sound in \Windows
playsound.exe \windows\loudest.wav
Vibrate a Touch Pro 2 for half a second
playsound.exe 1 500
Notes
Remember to enclose the path in quotes if you have spaces in the path name to your file, or else PlaySound will interpret it as multiple arguments and think you want to vibrate. (for example, playsound.exe "\Program Files\My App\Sound.wav")
License
This app is released into the public domain with no warranty. That means you can redistribute it at will and do not even have to give me credit. I would appreciate credit, though. ;-) Enjoy!
Requirements
At least WM5 (fully compatible with WM6/6.1/6.5). It should work on touchscreen and non-touchscreen devices both, but I haven't tested it on a non-touchscreen device yet.
Updates
It's highly doubtful that I will ever update this app. If you need more features, feel free to use the source and compile your own!

if argc is either 2 or 3 they do their thing and return 0, otherwise the routine follows and returns -1, that's the trigger
EDIT: wait, I think I just said a very stupid thing... this is my second guess: for not knowing ANYTHING about wm programming, I think that argc is the number of arguments passed to the program (as in ARGument Count), while argv[] is the (ARGument Value) index for those parameters

You are correct. argc just counts the number of arguments passed to the application. argv contains the arguments. To make it more confusing, the application path is also passed in. So argv[0] is the app path, argv[1] is argument 1, argv[2] is argument 2, etc. So, argc (argument count) is 2 when there is actually one argument passed in (because the first argument is the app path and the second the first argument).
argv is a string array, so you have to convert the string into a numeric value if you want to do numeric processing, and that's what the _ttoi() function does for the LED index and wait value.
And, there you have it.

dynamically setting image resources

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?
apreesh
33 views
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.

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

[XAP][SOURCE] WP8 Registry Tools

Rebranded to WP8 Registry Tools from Lumia Registry Modifier
This is a basic registry viewer/editor demonstration using Registry dlls pulled from Nokia xaps within the latest FFUs.
First, a few things to note.
1) This only retrieves values from HKEY_LOCAL_MACHINE
2) It CAN read DWORD values now, but can't write. (Hell you probably won't be able to write ANYWHERE, but the code is there)
Instructions are quite simple.
To Read Values:
1) Put the Registry key in the first box (ex. SOFTWARE\Classes\MIME\Database\Codepage\1254
2) Put the Registry Value in the second box (ex. 1254)
3) Press Get Value.
To Set Values:
1) Put the Registry key in the first box (ex. SOFTWARE\Classes\MIME\Database\Codepage\1254
2) Put the Registry Value in the second box (ex. 1254)
3) Put the new registry value result in the Set Value box.
4) Press Set Value.
This is very very basic, but I wanted to just show off something using what Nokia has provided us.
We can't write dword values unfortunately so hopes of using this to change the MaxUnsignedApp value are lost. This MAY be possible with @GoodDayToDie 's WP8NativeAccess library, but with this it isn't.
In case everyone wondered what that key is... SOFTWARE\Microsoft\DeviceReg\Install
Side load away
Hmm... I get Access Denied in my library on most keys that I've tried to write. If you can write the codepage, that's interesting (generally speaking, HKLM has stronger protections). I'll double-check whether I can write there myself. If not, but you can, then we have an elevated privilege attack vector...
Also, we should see whether the app runs on non-Nokia devices. I suspect that it will, if it works the way I think it does, but in that case it also won't have much in the way of permissions.
Getting DWORDs to work is a good project, I'm sure it's possible (works fine in NativeAccess, incidentally).
EDIT: Any chance you could include the source?

This is a basic registry viewer/editor demonstration using Nokia's Native Registry dll pulled from one of their apps.
First, a few things to note.
1) This only retrieves values from HKEY_LOCAL_MACHINE
2) DWord values aren't supported.
Instructions are quite simple.
To Read Values:
1) Put the Registry key in the first box (ex. SOFTWARE\Classes\MIME\Database\Codepage\1254
2) Put the Registry Value in the second box (ex. 1254)
3) Press Get Value.

Hi I found the Registry item
(File path : <ffu>\Windows\Packages\RegistryFiles\SOFTWARE.REG)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\KindMap
where we can set extensions and their types.so is it possible to add a new extension so that it will also be supported and visible in sdcard ?

It doesn't support creating new key values, only modifying existing ones. If the data is within one key value and it's able to be read, then it should be able to have things added to it.
EDIT: From what I've seen, what you're trying to do won't be possible with this. Each extension has a different key value.
We may need to start an "interesting registry values" thread here, similar to the one for WP7. Of course, it'll be more interesting if we can actually change any of them.
Oh, and the app works on my ATIV S, just by the way. Need to find some interesting paths to test it on, though.
EDIT: Have you been able to write to *any* values using this? It fails for me every time, but I haven't tried that many yet.

it has failed for me also. The only values I could write to were the ones that corresponded to Nokia. I'll look through the code again and make another update. I'm going to also rebrand it since it works for non Lumia phones.
Interesting about the Nokia paths working. That could be some characteristic of the DLL you use having better permissions or something specific to OEM stuff, but I actually suspect it's just that Nokia didn't bother to lock down the ACLs on their parts of the registry. You can easily adapt the app to my NativeRegistry class to test this, if you want.
Hmm that's a good idea. I just rebranded it to WP8 Registry Modifier. I'll add in your NativeRegistry class to work along with the RegistryRT class to see what comes about.
DWORD support
For DWORD support, take a look at the Nokia.SilentInstaller.Runtime.wim... The "CSilentInstallerRuntime" class contains multiple methods to interact with the registry including:
CreateKey
GetRegDWORDValue
GetRegSZValue
GetRegSZValueL
IsRegistryDWORDValueExists
IsRegistryKeyExists
IsRegistryREGSZValueExists
SetRegDWORDValue
SetRegSZValue
A bit off topic, I found a way to launch any URI... Literally, ANY URI (app:// http:// or anything). I can launch any application (using the GUID - so it must be a registered application but doesn't have to be one that you see in your programs list) and go to a specific page within that application. I can also pass any kind of query string that could unlock some hidden features in an application (such as the Extras+Info application - I can launch it using any dial string even though my ROM has that particular dial string disabled). I do so by launching a Toast message which allows me specify a launch uri and once it pops up, I click it. If anyone's interested, I can post a code sample for that...
@GoodDayToDie I'm able to read DWORDs with your NativeRegistry framework. I haven't been able to write though (I've only looked at the MaxUnsignedApp reg value).
What I think I'm going to do is possibly scrap the RegistryRT framework and just use yours. I can then make an even more robust app.

I was actually looking at the SilentInstaller not long ago. I got sidetracked by the fact that I could use the NativeRegistry read DWORD values. I'll check that out and upload a new build in a few

I can write one up later. I have several registry keys that I'd like to bring attention to.
NOTE: I don't see anything editable yet, at least I can read it to compare it to the files in the ffu.
Launching a URI should be possible more directly than that, using ShellExecute, or similar, but that way is cool (and doesn't require importing unofficial native functionality).
Just a word of warning: NativeRegistry is under heavy modification. I hope to have the next Alpha release done soon, which brings a ton of changes, but in the meantime you might want to follow the changes on CodePlex; while I test every build that I push, I don't always publish the binaries.
There will be two ways to use the registry through NativeAccess soon: one is to use fairly thin wrappers around the native functions (that's mostly what's implemented now, but it will be expanded to include key and value enumeration, key creation, etc.), and the other is to use a class more akin to a .NET RegistryKey class, offering the ability to interact in a more object-oriented manner (where the object itself represents an open key).
Something I did notice when I tried to compile the NativeRegistry source (I just ended up using the binary you had for my testing) is that it kept blowing up on the include for WinReg.h. I don't have that anywhere. Am I missing something?

I'm not sure how GoodDayToDie did it himself (probably same approach I take it) but I compiled it using the "WinReg.h" from the Windows 8 SDK and removing the desktop-only compiler "if" instruction (lines 49 and 1446). And like he mentioned, you also have to create the KERNALBASE.LIB with the required registry export functions for the linker.

Yes, please post your code and give yourself your own thread (at least keep it here in development ). There are a lot of underlying dialer codes that Nokia disabled when flashing the 928s. Also this could mean we could have a custom app launcher, if you wanted to customize it that way. Most of the work we have done on WP8 has occurred in the past few months; we are finally getting so close to the first InteropUnlock for Nokia/WP8.
Sent from my RM-860 (Lumia 928) using the OFFICIAL Tapatalk app.
I'm trying to figure out the correct method prototype (since this is a method that appears to be WinPhone only and isn't part of the SDK so, no details on it whatsoever)... I stumbled upon this toast functionality in "NokiaFrameworkOBAWinPRT.dll" under the "DevPropHelper" class. The method to call is "InvokeToast". This method ends up calling "Shell_PostMessageToast" in "ShellChromeAPI.dll" (this is what I'm trying to invoke directly without going through the Nokia dll).
Add a reference in your project to "NokiaFrameworkOBAWinPRT.winmd" (you can find this in newer versions of the Extras+Info app)
Add the necessary <InProcessServer> tag (to allow the "NokiaFrameworkOBAWinPRT.DevPropHelper" class) in the <ActivatableClasses> section of you WMAppManifest.xml file
In the code... Create an instance of "NokiaFrameworkOBAWinPRT.DevPropHelper"
In the code... Call the "InvokeToast" method (of the previously created object) passing it:
Application GUID (can be your local app's GUID - doesn't seem to matter)
URI to launch in string format
Toast title (can be anything)
Toast content(can be anything)
When the Toast notification pops up, click on it and that's it.
