How to set the wallpaper in Android

1. Call the system's Intent.ACTION_ATTACH_DATA. This Intent will evoke all the wallpaper program and the contact avatar program. Users can choose through ChooseActivity:

This Intent is a standard Intent, so all settings will be supported

 Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
        (Intent.FLAG_GRANT_READ_URI_PERMISSION);
        ("mimeType", "image/*");
        Uri uri = (
            .insertImage(getActivity().getContentResolver(),
                ((BitmapDrawable) wallpaper).getBitmap(), null, null));
        (uri);
        startActivityForResult(intent, SET_WALLPAPER);

2. Set up through WallpaperManager

This method can directly place the picture as a wallpaper, which is used for Android systems on all platforms, but it is impossible to crop/adjust the picture.

try {
  WallpaperManager wpm = (WallpaperManager) getActivity().getSystemService(
        Context.WALLPAPER_SERVICE);

  if (wallpaper != null) {
    (bitmap);
    ("xzy", "wallpaper not null");
  }
} catch (IOException e) {
  (TAG, "Failed to set wallpaper: " + e);
}

Authorization required:

<uses-permission android:name = ".SET_WALLPAPER"/>
