[CODE] Check for root

Hey guys.. I'm writing my first root app and I'm trying to write a method to check for root. Here is what I have so far.. (go easy on me I'm no expert yet )
Code:
public void checkRoot(){
Process p;
try {
// Perform SU to get root privledges
p = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(p.getOutputStream());
os.writeBytes("remount rw");
os.writeBytes("echo Root Test > /system/rootcheck.txt");
os.writeBytes("exit\n");
os.flush();
try {
p.waitFor();
if (p.exitValue() != 255){
//Phone is rooted
Log.d(TAG, "Phone is Rooted");
}
else {
//Phone is not rooted
Log.d(TAG, "Phone is not Rooted");
}
} catch (InterruptedException e) {
}
} catch (IOException e) {
}
}
It "seems" to be working if the phone is rooted without SuperUser installed, but it doesn't work if the accept deny prompt is given... it doesn't seem to be waiting after "p = Runtime.getRuntime().exec("su");" for the superuser check to complete. I could manually put a delay in but that would create lag when things are already approved.
I could be approaching this in the completely wrong way but if any coders have a root check function that works efficiently I could borrow or help me correct mine I would appreciate it.
Thanks in advance for anyone who can be of some help! I have googled this subject up and down but searching anything involving root or superuser creates piles of irrelevant results.

This has been addressed often, you can find one example in this post. Look at my "Mr Teacher" post: except for my attitude, the informations I provided should help you.

2G/3G Preferred Network Mode with root?

I'm trying to access the hidden API for Phone.class to switch the preferred network mode via reflection.
I know this is not safe for porting to other android versions/roms and requires a system app to hold permission WRITE_SECURE_SETTINGS.
I Already managed to switch data via reflection and toggle gps via Settings.Secure.putString() by moving my app to system partition, so i think this should work too.
Does anyone have experience with reflection and/or root and is willing to help?
Of course I will share all my code/findings here.
Thanks in advance!

You can achieve this with a simple sqlite3 query instead of bothering with java reflection
Here's how :
In a terminal :
To enable 2G only
Code:
su
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
insert into global values(null, 'preferred_network_mode', 1);
.exit
To enable 2G & 3G :
Code:
su
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
insert into global values(null, 'preferred_network_mode', 0);
.exit
In java :
Example to enable 2G only (just replace the 1 with a 0 in the insert into to enable 2G & 3G)
Code:
try {
Process process = null;
process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(
process.getOutputStream());
os.writeBytes("sqlite3 /data/data/com.android.providers.settings/databases/settings.db" + "\n");
os.writeBytes("insert into global values(null, 'preferred_network_mode', 1);" + "\n");
os.writeBytes(".exit" + "\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
It might require a reboot to be active though, not sure
If it doesn't work on your rom (tested on cm10.1), it might be a different row name, try investigating your settings.db like this :
Code:
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
.tables [COLOR="Green"]// returns all the tables[/COLOR]
select * from [I]tablename[/I]; [COLOR="green"]// in cm10.1 it's in [I]global[/I] but otherwise look in [I]secure[/I] and/or [I]system[/I]
// this command returns all the rows from the selected table, the names are usually explicit, so you should find the setting you're looking for[/COLOR]
Then, when you found it :
Code:
insert into [I]tablename[/I] values(null, [I]'row name'[/I], value);

Thanks, this is very helpful!
I think you are right, one will need to tell the system to update the settings or send a broadcast that this setting has changed (like for airplane mode).
I will look at the CM sources to find out what i can do.

Glad it helped.
If you manage to find a way to make the settings read the db without a reboot, please share your findings, would be very useful.

Buddy... you can toggle network mode with intent, no root needed, nor permissions!!
Here´s entire sample:
Code:
package com.serajr.togglenetworkmode;
import android.os.Bundle;
import android.provider.Settings.Secure;
import android.provider.Settings.SettingNotFoundException;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bnt = (Button) findViewById(R.id.button1);
bnt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// toggle
toggleNetworkMode();
}
});
}
private void toggleNetworkMode() {
int mode = getCurrentNetworkMode() + 1;
if (mode > 2) {
mode = 0;
}
// 0 = 3G_ONLY
// 1 = 3GSM_ONLY
// 2 = 3G_PREFERRED
// change mode
Intent intent = new Intent("com.android.phone.CHANGE_NETWORK_MODE");
intent.putExtra("com.android.phone.NEW_NETWORK_MODE", mode);
sendBroadcast(intent);
}
private int getCurrentNetworkMode() {
try {
int current = Secure.getInt(getContentResolver(), "preferred_network_mode");
return current;
} catch (SettingNotFoundException ex) {
return 0;
}
}
}
Try it and tell me later!!!

Thanks, but this will only work if your phone.apk has an exported receiver for this intent.
This is only the case if you or your rom dev modded it to be so.
Some custom ROMs also have this kind of "mod/bug" in the power widget, allowing you to toggle gps.
I tried it with slim bean 4.2 build 3 on i9000 and as expected it didn't work (and so will most likely in CM10.1 too).
Just too good to be true!

If youre following the root method Use RootTools for that

Thanks, I already do.
Really helpful library!
And yes, I will do it by sql injection to settings.db
I only need to figure out what broadcasts have to be sent / methods called and if this is possible.

Argh I am kinda lost in CM sources.
Can anyone point me to the place where this is handled?
I managed to toggle flight mode by using this in a SU shell:
Code:
if(settingenabled)
{
executeCommand("settings put global airplane_mode_on 1");
executeCommand("am broadcast -a android.intent.action.AIRPLANE_MODE --ez state true");
}
else
{
executeCommand("settings put global airplane_mode_on 0");
executeCommand("am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false");
}
Interstingly enough it didn't work if i manually injected the value and then sent the broadcast.
I have no idea why.
So atm I'm trying to do the same thing for preferred_network_mode. I can write the value to settings.db, but I just don't know what i have to do to make the system apply the setting yet.
EDIT: shell binary "settings" only works in android 4.2 (and probably upwards)

So i finally found it in CM Sources.
Seems like we need to get the currently running Instance of the Phone class to notify it about the change.
Also seems like we are back to reflection, as this is an internal system class.
I also killed com.android.phone process after updating the setting, but that didn't change anything.
EDIT:
1st step towards reflection:
I figured out that i need a jar file from the cm build to use system classes via reflection.
Does anyone have more information about this?

Just a far fetched guess, but maybe try to add /system/framework/framework.jar from your rom to your app's build path
Is a reboot that unacceptable in your case ?

Maybe it's just the challenge, but i wanna change it like every other setting
A reboot is very far from what i call comfortable

Yeah, I get what you mean^^^
Here's a good (but old, 2009^^) official Android tutorial from the Android devs on reflection if it can help you : http://android-developers.blogspot.fr/2009/04/backward-compatibility-for-android.html

So i got some news
1. This setting is heavily protected by android system and can only be modified by the phone process itself
2. Some roms have a modified phone apk listening to a broadcast, enabling 3rd party apps to toggle
http://forum.xda-developers.com/showthread.php?t=1731187
3. His Majesty Chainfire started an app project which could amongst other features also toggle 2g/3g, but he gave up development. Regarding 2g/3g he implemented several methods, one of them being RIL injection, which he described as a really hard hack and highly experimental.
http://forum.xda-developers.com/showthread.php?t=807989
Seems this task is not that easy
But i found out that tasker can toggle 2g/3g on my phone (running slim bean 4.2.2), this is when i found out about the modified phone.apk from 2). So I'mcomfortable that it's working on my phone and i can at least develop an app for myself

[HELP] Native Toast Launcher

I was able to install the HTC Sprint Diagnosis app on my Nokia Lumia 1520 and also have the HTC CSDDiag app installed.

I have tried install other platform Diag tools but was only able to install the two above using fiddler ( thanks ngame for your tutorial )

Who did you do that ? I Try it many times before to install these aps on RM-821 Nokia Lumia 920 but didn't work !
how did you do that ? Could you please P.M Me ?

It wasnt hard to install those apps. Just followed the fiddler tutorial posted.
Then I connected the phone and installed SysPushApp onto the device and did an update for the SysPushApp to get the non_OEM files of Samsung and HTC . I couldnt install Samsung Diagnosis as it wasn't letting nor was I able to install HTC Hub ( I dont know why, may be they check some .dll specific to them in the phone before install ) .
Change the oSession in fiddler config file to the specific OEM you want to install the app. Example for HTC[ ->
oSession (NOKIA)
(NOKIA), (HTC) /B]
Mt device is Dev-Unlock.

Samsung diagnosis already removed from wp store so you can't install it easy
and diagnosis you can see in store may different from one in Samsung phones! If you check file sizes you will get what i say
Most of HTC apps only can install ID_Resolution_HD720p and WVGA devices i don't know how is it possible to deploy them on 1080 devices
maybe MS accept this resolution for all apps because the old apps have to add 1080 support?

I don't have this xaps but you have to use .Net Reflector 8 or any .net Decompiler then u can see all hidden xamls after _default you have to enter a #/ then dll name without it's dll them a ; and then folder and xaml address
example :
app://GUID/_default#/dllname;Pages/ExamplePage.xaml

OMG!!!!!!!! so many xamls !
If you can get a Screen Shot of each xaml is more useful I think

None of them works. We need to add Dialercodes in the end.

its alright mate.thanks for your help. I will try tomorrow.
did you check the xap's i posted in the other thread. I hope they will be useful. Thanks.
btw my phone came with Hong Kong firmware but I have installed the Australian firmware. Im glad atleast this was possible.

@nGage were you able to install those apps on your phone ?

@nGage there is some good news i was able to run the strings which you posted. It was all about changing 'Component' -> 'component' and some other tweaks. But the .dll library refers to something else and hence the data is not fetchable. I will post the screenshots tomorrow. @W_O_L_F can this file 'HTC Diagnostics_Sprint be hacked in any way as I was able to install this on Nokia 1520 via Windows App Store -> SysPush ( via Fiddler i.e chainging the OEMID=HTC )

Not for Nokia.

Be very careful with the HTC Sprint tool, since it has the ability to change NV values, even if it is commented out. (don't know why.) but it sure does.

thanks for the advice. But the app is pointless on Nokia phones as i have tried it and it doesn't work ... It can go to the menu's bit cannot get the values either it needs Interop or the dll linked is not for the device.

How to search StorageFiles

I need a way to search in StorageFiles with dynamically pattern, which comes from a TextBox. The directive "Windows.Storage.Search" doesnt exist in windows phone 8.1 runtime, as i saw. Now my question is, how can i do this in alternative way?

The only way to do it with WP 8.1 since Microsoft ALWAYS fails to implement the important things are to query using LINQ.
Ex:
Code:
var result = (await Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).
Where(x => x.Name.
Contains(x => txtBox.Text));
That's about all you can do pretty much. (Thanks Microsoft).

Thank you for the example. But it wont work for me, it shows me the following error(s):
Code:
A local variable named 'x' cannot be declared in this scope because it would give a different meaning to 'x', which is already used in a 'parent or current' scope to denote something else
and
Code:
Cannot convert lambda expression to type 'string' because it is not a delegate type
Thats really odd from Microsoft, that they havent implementet the search function like in WinRT (Windows Store App).

The first error is pretty simple. You already have the variable named "x" and it would be very bad if compiler didn't give you that error.
Change the name of the variable to something else that you don't use in that scope and it will work.
And for second problem, try this one:
Code:
private List<string> Result()
{
var result = ((List<Windows.Storage.Search.CommonFileQuery>)Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).Where(x => x.ToString().Contains(txtBox.Text));
return result as List<string>;
}
private async Task<List<string>> ResultAsync()
{
return await Task.Run(() => Result()).ConfigureAwait(continueOnCapturedContext: false);
}
You should call ResultAsync method and get the result in this way:
Code:
List<string> myList = ResultAsync().Result;

That's not going to work. You can't cast a StorageFile as a string.
To fix my code (simple lambda typo)
Code:
var result = (await Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).
Where(x => x.Name.
Contains(txtBox.Text));
if(result.Any())
{
// Do shtuff
}
Also, you should never access the .Result of an async task because you never know if it completed yet.

Ok, first error is done, but the second error is still here
Code:
Cannot convert lambda expression to type 'string' because it is not a delegate type

You are missing the point of the TAP (Task Async Pattern).
Both main thread and async method will be in execution in the same time. When the async method finish his work, main thread will stop and catch the result trough the Result property.
TAP is the recommended way of asynchronous programming in C#. The only thing with TAP is to use ConfigureAwait method in non-console type of apps to avoid deadlock.
Sooner or later you will get the result from TAP method. Nothing will get in the conflict with the main thread.

Oh wait, @andy123456 I updated my response. I forgot String.Contains ISNT a lambda .
@Tonchi91, I know all about the TAP. I've been using it since it was CTP. I've seen the awkward situations with threading in WP .

Now... if he did
Code:
List<string> myList;
ResultAsync().ContinueWith(t=> { myList = t.Result; });
I wouldn't be worried .

Ok the errors are gone, but the debugger show me the following exception:
Code:
Value does not fall within the expected range
Is this search method case-sensitive? I tried with an exact input in the TextBox.

Hmmm. Let's see your full code.

its actually only for testing, so i added your code to a button (asnyc) and will show the output in a textBlock.
Code:
private async void buttonTest_Click(object sender, RoutedEventArgs e)
{
//Result();
var result = (await Windows.Storage.KnownFolders.CameraRoll.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).
Where(x => x.Name.
Contains(textBox_test.Text));
if (result.Any())
{
// Do shtuff
textBlock_test.Text = result.ToString();
}
}
The error is coming from here
Code:
var result = (await Windows.Storage.KnownFolders.CameraRoll.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName))

Oh Camera Roll.. You MIGHT need to have the capability to view the camera roll enabled. I forget what it's called, but you need a specific cap in order to view from there. Also, I would try to see if you can use a generic folder instead.
I would try Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync() as your method after the await just to test whether you can read correctly.

Yes but in wp8.1 runtime app, there arent caps anymore. The capability for access to the pictures is simply calles pictures library and is enabled. I have tested it as you said, but it gives me the same exception.

A quick tip: another way to do this is to use the Win32 C runtime API. You can, for example, use the FindFirst/NextFile functions (http://msdn.microsoft.com/en-us/library/windows/desktop/aa364418(v=vs.85).aspx) which support searches using wildcards (* and ? characters in the first parameter). These functions are wrapped in my NativeLibraries classes, but are also just publicly available for third0party developers to call from their own C++ DLLs.
Alternatively, you can use the .NET System.IO.Directory class, which has functions like EnumerateFiles(String path, String searchPattern). This is probably the better way to do it, actually.
Of course, if you want these operations to not block the current thread, you'll need to explicitly put them in their own thread or async function.
EDIT: This also assumes you have read access to the relevant directories. You application data directory works fine, for example (you can get its path from the relevant StorageFolder object). Other directories that can be accessed via WinRT functions may go through a broker function instead of being directly readable.

The point is, that i have an array with filenames. Now i need the StorageFile files which contains these filenames. My idea was to search for these files and return the files as StorageFile, so i can work with these. Or is there a simpler / another way?

http://msicc.net/?p=4182 <-- try this

Thank you, i have already done this and its working. But how can i compare the Files to read, with already read files and take only the not yet read files?

[Tutorial] Manage System Permissions in Android Marshmallow

Hello,
I create that thread to offer you a new tutorial aiming to learn how to manage System Permissions in Android Marshmallow. You can discover the tutorial in video also :
Manage System Permissions on Android 6 Marshmallow
Beginning in Android 6 Marshmallow, users grand permissions to apps while the app is running, not when they install the app. This approach gives the user more control over the app's functionality. Thus, he can choose to give the access to read contacts but not to the device location. Furthermore, users can revoke the permissions at any time, by going to the app's Settings screen.
Note that system permissions are divided into two categories : normal and dangerous. Normal permissions are granted automatically. For dangerous permissions, the user has to give approval to your application at runtime. So, developers must manage permissions at runtime before using some dangerous features.
To manage permissions inside an application, we're going to imagine we want to read contacts. This feature will use the READ_CONTACTS permission that is marked as dangerous. So, the first step is to check for READ_CONTACTS permission. If the permission has already been granted, you can use the feature that read contacts. If not, you have to request for permissions with a custom request code that will be named MY_PERMISSIONS_REQUEST_READ_CONTACTS in our example.
Code:
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[] { Manifest.permission.READ_CONTACTS },
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
} else {
readContacts();
}
Note that when your application requests for permissions, the system shows a standard dialog box to user that cannot be customized. Now, you need to handle the permissions request response by overriding the onRequestPermissionsResult method :
Code:
@Override
public void onRequestPermissionsResult(int requestCode,
@NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_READ_CONTACTS :
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
readContacts();
} else {
if(ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.READ_CONTACTS)) {
new AlertDialog.Builder(this).
setTitle("Read Contacts permission").
setMessage("You need to grant read contacts permission to use read" +
" contacts feature. Retry and grant it !").show();
} else {
new AlertDialog.Builder(this).
setTitle("Read Contacts permission denied").
setMessage("You denied read contacts permission." +
" So, the feature will be disabled. To enable it" +
", go on settings and " +
"grant read contacts for the application").show();
}
}
break;
}
}
Like you can see, managing permissions in your Android application is not really hard.
Don't hesitate to give me your feedbacks or ideas for new tutorials.
Thanks.

They were intimidating at first but once you do it once, you've pretty much got the hang of it.

True. When you understand the mechanism, it becomes simple to use permissions in your Android code.

@sylsau Thanks..
BTW, does this work properly on Android 5.1.1 and below?
I mean, what does this below code do for 5.1.1 and below? :
Code:
ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)
Does it always return true, or is there a chance of exceptions or errors?
I'm asking this because I don't have Android Device below 5.1 to test it..
Or should I wrap it up like this:
Code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions();
}
