Android Set Wallpaper Using Intent

I am trying to make wallpaper application. I am able to set the wallpaper using wallpaper manager. But what i want is when i click a button a new intent should open which should be

Solution 1:

This is a better solution, wher you dont have to specify a target app;

Intentintent=newIntent(Intent.ACTION_SET_WALLPAPER);
startActivity(Intent.createChooser(intent, "Select Wallpaper"));

Solution 2:

Use "android.intent.action.SET_WALLPAPER" + set component/class of your wallpaper application so that the Intent would be handled by your app.

For example, that'd look like as follows for AOSP built-in wallpaper application:

Intentintent=newIntent("android.intent.action.SET_WALLPAPER");
// Change the following line with that of your own app
intent.setClassName("com.android.launcher", "com.android.launcher2.WallpaperChooser");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    Log.wtf(TAG, "No activity found to handle " + + intent.toString());
}

Solution 3:

I know its late but for someone to wants, its works for me.

finalWallpaperManagerwallpaperManager= WallpaperManager.getInstance(this);
    finalDrawablewallpaperDrawable= wallpaperManager.getDrawable();
    try {
        wallpaperManager.setBitmap(yourImageView.getDrawingCache());
        finish();
    } catch (IOException e) {
        e.printStackTrace();
    }
