Set Remote Image as Wallpaper Asynchronously

In this post, you would learn how to Set Remote Image as Wallpaper Asynchronously. 

Important Key Notes: 

• To use WallpaperManager, minimum API level have to be set to 5.
• Add the relevant permissions to your AndroidManifest.xml file: <uses-permission android:name="android.permission.SET_WALLPAPER">
• A different thread should be used, because setting wallpaper is a time consuming task.  Otherwise you may get ANR error. Here, I have used Async Task.

private class SetWallpaperAsyncTask extends AsyncTask<String, Void, String> {

   
   @Override

   protected String doInBackground(String... params) {

   String URL = "path/of/remote/image";

   setWallpaper(URL);

   return "Executed";

   }      

   @Override

   protected void onPostExecute(String result) {

   }

   @Override

   protected void onPreExecute() {

   }

   @Override

   protected void onProgressUpdate(Void... values) {

   }

        

   private void setWallpaper(String url) {

   try {

      WallpaperManager wpm = WallpaperManager.getInstance(ActivitySinglePage.this);

      InputStream ins = new URL(url).openStream();

      wpm.setStream(ins);

      } catch (Exception e) {

      e.printStackTrace();

      }

  }

}

Then call from where you need

new SetWallpaperAsyncTask().execute("");
