Answer 1

You need to use the WallpaperManager Class if You develop higher API Level 5:

WallpaperManager mManager = WallpaperManager.getInstance(getApplicationContext());

  try {
      mManager.setResource(R.drawable.yourDrawable);
  } catch (IOException e) {

   //warning for the user
e.printStackTrace();

   }

And to use the manager, You need to set permissions SET_WALLPAPER in the manifest. Also, if You develop under API Level 5 and You want to use the method that You used, You have to set the Permission too.

Answer 2

Have you added the wallpaper permission to your manifest?

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

Try this way,hope this will help you to solve your problem.

Declare WallpaperManager object at class level :

private WallpaperManager wallpaperManager;

Initialize WallpaperManager object in initialize() :

private void initialize() {
  wallpaperManager = WallpaperManager.getInstance(this);
}

Set bitmap to wallpaperManager object.

case R.id.btnSetWall:
   try {
       if(bmp!=null){
           wallpaperManager.setBitmap(bmp);
       }else{ 
           // write your bitmap null handle code here.
       }
   } catch (IOException e) {
     Log.e(TAG, "Cannot set image as wallpaper", e);
   }
   break;

Add this permission to AndroidManifest.xml :

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