How to set wallpaper in Android app

In order to set the wallpaper from within an Android app, you'll have to create an instance of the WallpaperManager class and set the resource from within a try catch block. See the example below:

public void onClick(View arg0) {

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

try {

mywall.setResource(R.drawable.nameOfFile);

} catch(Exception e) {


e.printStackTrace();



}



}
