Set wallpaper image from Gallery programmatically in Android

Follow the stapes and intregrate the pice of codes in your application :

1.  final int RESULT_LOAD_IMAGE=1;

2.call this intent to open gallery and select an Image:

Intent i = new Intent(Intent.ACTION_PICK,

                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(i, lodImage);

3. Now on Activity result you can get the selected image path and you can set the Wallpaper :

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);

         

        /*

         * if request made to select a image from gallery

         */

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {

           String wallpaper= selectedWallpaperImage(getApplicationContext(),data);

           WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);

           

           try {

wallpaperManager.setBitmap(BitmapFactory.decodeFile(wallpaper));

                         //this line of code will set the selected image as your wallpaper...........

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

        }

    }

4.You need this method to get the Gallery image path

public static String selectedWallpaperImage(Context context,Intent data){

Uri selectedImage = data.getData();

     String[] filePathColumn = { MediaStore.Images.Media.DATA };

     Cursor cursor = context.getContentResolver().query(selectedImage,

             filePathColumn, null, null, null);

     cursor.moveToFirst();

     int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

     String picturePath = cursor.getString(columnIndex);

     cursor.close();

return picturePath;

}
