GWD sources - Samsung Galaxy Watch

It seems the ALARM and NOTIFICATION sources aren't shown in GWD. But they may be useable by modding the xml. Likely as sources for a hand, text, digital clock etc.

Hello guys,
I want to share my library XClasses.
My idea was to see every XClass as an extension of the original class.
My aim was to improve the user experience during the development.
Also I wanted to increase the readability of xposed code.
So it's nothing special.
It's just my personal opinion how readable code should look like.
A small example:
Code:
public class XposedMain implements IXposedHookLoadPackage
{
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam)
throws Throwable {
if(lpparam.packageName.equals("com.android.systemui"))
{
XposedHelpers.findAndHookMethod(TextView.class, "setText", CharSequence.class, TextView.BufferType.class, boolean.class, int.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param)
throws Throwable {
TextView tv = (TextView)param.thisObject;
CharSequence text = (CharSequence)param.args[0];
TextView.BufferType type = (TextView.BufferType)param.args[1];
boolean notifyBefore = (Boolean)param.args[2];
int oldlen = (Integer)param.args[3];
XposedBridge.log("setText "+text+" with size "+tv.getTextSize());
}
});
}
}
}
The same code with XClasses:
Code:
// class 1
public class XposedMain implements IXposedHookLoadPackage
{
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam)
throws Throwable {
if(lpparam.packageName.equals("com.android.systemui"))
{
setup(lpparam.classLoader);
hook(XTextView.class);
}
}
}
// class 2
public class XTextView
extends AbstractXClass<TextView>
{
public static String getOriginalClassName() { return TextView.class.getCanonicalName(); }
public XTextView(TextView objectThis) { super(objectThis); }
@BeforeOriginalMethod
private void setText_Before(CharSequence text, TextView.BufferType type,
boolean notifyBefore, int oldlen) throws Throwable {
XposedBridge.log("setText "+text+" with size "+getThis().getTextSize());
}
}

We are working with a Galaxy S3 (Android 4.1.1). We are able to get the activity from param.thisObject and change the title by getting the activity and calling setTitle(), but when we want to start a new activity, the activity doesn't start. Does anyone know how to spawn a new activity?
Our code is building off of SmileyClock in the tutorial.
Main.java

Does anyone know where I can find code handling the current live wallpaper engine / view? I am trying to extract the live wallpaper for further processing (e.g. blurring).
I already found an entrance point: If the LWP used the standard com.android.internal.view.BaseSurfaceHolder supplied by the base class android.service.wallpaper.WallpaperService.Engine i can hook into lockCanvas and unlockCanvas to grab the image. But most LWPs do not use this, so I need another (more general) solution.
I thought about hooking all subclasses of android.service.wallpaper.WallpaperService, but AFAIK that's not possible without loading every single class and check if it's a subclass.
Any ideas?
Implementation for reference:
Code:
public class Hook implements IXposedHookLoadPackage {
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {
final Class<?> engingeClass = findClass("android.service.wallpaper.WallpaperService.Engine", loadPackageParam.classLoader);
final String packageName = loadPackageParam.packageName;
final Class<?> surfaceHolderClass = findClass("com.android.internal.view.BaseSurfaceHolder",loadPackageParam.classLoader);
findAndHookMethod(engingeClass, "getSurfaceHolder", new XC_MethodHook() {
private boolean isFirstCall = true;
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
Field field = findField(param.thisObject.getClass(), "this$0");
WallpaperService service = (WallpaperService) field.get(param.thisObject);
WallpaperManager wallpaperManager = WallpaperManager.getInstance(service);
if (isFirstCall && wallpaperManager.getWallpaperInfo().getPackageName().equals(packageName)) {
isFirstCall = false;
XposedBridge.log("Got context. Set up hooks...");
hook(surfaceHolderClass,service);
}
}
});
}
Bitmap bitmap;
Canvas internalCanvas;
Canvas originalCanvas;
private void hook(Class<?> clazz, final Context context) {
hookAllMethods(clazz, "lockCanvas", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
originalCanvas = (Canvas) param.getResult();
bitmap = Bitmap.createBitmap(originalCanvas.getWidth(),originalCanvas.getHeight(), Bitmap.Config.ARGB_8888);
internalCanvas = new Canvas(bitmap);
param.setResult(internalCanvas);
XposedBridge.log("Locked Canvas");
}
});
findAndHookMethod(clazz, "unlockCanvasAndPost", Canvas.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
originalCanvas.drawBitmap(bitmap,0,0,null);
param.args[0] = originalCanvas;
Intent intent = new Intent("com.faendir.lwpextractor.WALLPAPER_CHANGE");
ByteArrayOutputStream bs = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG,100,bs);
intent.putExtra("bmp",bs.toByteArray());
context.sendBroadcast(intent, "com.faendir.lwpextractor.RECEIVE_WALLPAPER_CHANGE");
XposedBridge.log("Unlocked Canvas");
}
});
}
}

So, I'm getting fairly good at hooking and modifying classes, but this one is so unique, I'm not quite sure how to approach hooking it to do what I want. Code for the method/class I want to attack:
Code:
private class CreateLaunchPointListTask
extends AsyncTask<Void, Void, List<LaunchPoint>>
{
private CreateLaunchPointListTask() {}
protected List<LaunchPoint> doInBackground(Void... paramVarArgs)
{
paramVarArgs = mContext.getString(2131558445);
Object localObject = new Intent("android.intent.action.MAIN");
((Intent)localObject).addCategory(paramVarArgs);
paramVarArgs = new LinkedList();
PackageManager localPackageManager = mContext.getPackageManager();
localObject = localPackageManager.queryIntentActivities((Intent)localObject, 129);
int j = ((List)localObject).size();
int i = 0;
while (i < j)
{
ResolveInfo localResolveInfo = (ResolveInfo)((List)localObject).get(i);
if (activityInfo != null) {
paramVarArgs.add(new LaunchPoint(mContext, localPackageManager, localResolveInfo));
}
i += 1;
}
return paramVarArgs;
}
public void onPostExecute(List<LaunchPoint> arg1)
{
synchronized (mLock)
{
mAllLaunchPoints.clear();
mAllLaunchPoints.addAll(???);
synchronized (mCachedActions)
{
LaunchPointListGenerator.access$502(LaunchPointListGenerator.this, true);
if (!mCachedActions.isEmpty()) {
((LaunchPointListGenerator.CachedAction)mCachedActions.remove()).apply();
}
}
}
LaunchPointListGenerator.access$602(LaunchPointListGenerator.this, true);
Iterator localIterator = mListeners.iterator();
while (localIterator.hasNext()) {
((LaunchPointListGenerator.Listener)localIterator.next()).onLaunchPointListGeneratorReady();
}
}
}
So, while this is a big chunk of code, everything I want to do is really in the first few lines:
Code:
paramVarArgs = mContext.getString(2131558445);
Object localObject = new Intent("android.intent.action.MAIN");
((Intent)localObject).addCategory(paramVarArgs);
So, string 2131558445 is a specific intent. What I would like to do is add *another* category after 2131558445 is added to localObject.
That would be the simplest implementation.
A more advanced implementation would be to actually and return a second LinkedList, paramVarArgs2, that only matches up to the second intent category that we're inserting.
Any help would be greatly appreciated.

Hello, I have made this code
Link : http://hastebin.com/hiyupafibi.java
Duplicated here :
Code:
//In my module, I have this activity MainActivity, which has a function to generate random number
private int randomNumber() {
return (new Random()).nextInt(3);
}
//Toast this random number somewhere in the main activity
Toast.makeText(MainActivity.this, " " + randomNumber(), Toast.LENGTH_LONG).show();
//In XposedMod, make a hook
public class XposedMod implements IXposedHookLoadPackage {
private TextView tv;
public static final String PACKAGE_NAME = ".......";
@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
if (lpparam.packageName.equals(PACKAGE_NAME)) {
Class<?> MainActivityClass = XposedHelpers.findClass(PACKAGE_NAME + ".MainActivity", lpparam.classLoader);
XposedHelpers.findAndHookMethod(MainActivityClass, "randomNumber", new XC_MethodReplacement() {
@Override
protected Object replaceHookedMethod(MethodHookParam methodHookParam) throws Throwable {
try {
tv.setText("No NPE");
return 45;
} catch (NullPointerException e) {
return 44;
}
}
});
} else if (lpparam.packageName.equals("com.android.systemui")) {
Class<?> someClass = XposedHelpers.findClass("com.android.systemui.SomeClass", lpparam.classLoader);
XposedHelpers.findAndHookMethod(someClass, "someMethod", Context.class, new XC_MethodHook() {
@Override
protected Object beforeHookedMethod(MethodHookParam methodHookParam) throws Throwable {
tv = new TextView((Context) param.args[0]);
if (tv==null)
XposedBridge.log("tv is null, apologies!");
}
});
}
}
}
Everytime that toast is supposed to be shown, I get the answer to be 44 (that is, tv is null), but that should not be the case, because the log statement when tv is null is not shown. What am I doing wrong?
Thanks for the help, I appreciate it.
Cheers!
