set livewallpaper manually

i have created live wallpaper in android 2.1.X , now i want to call this code in my activity so that user can set my created live wallpaper throug开发者_运维百科h button click just like "Set Wallpaper" button.

As my livewallpaper code extends WallpaperService class so that i can't even call as an intent.

Check this link. It shows the code for how to add a picker. It uses WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER which is api level 7, so check you are compiling against the correct version.

The code:

public class OpenActivity extends Activity { private int REQUEST_CODE = 1;

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);

    Intent intent = new Intent();
    intent.setAction(WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER);
    startActivityForResult(intent, REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int
     resultCode, Intent intent)
{
  super.onActivityResult(requestCode,

resultCode, intent); if (requestCode == REQUEST_CODE) finish(); } }
