Question

I want to set the wallpaper on phone boot. How can I do that ?

Answer 1

In your manifest add this permission:

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

Later in your code:

WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);

Drawable drawable = getResources().getDrawable(R.drawable.wallpaper);

Bitmap wallpaper = ((BitmapDrawable) drawable).getBitmap();

wallpaperManager.setBitmap(wallpaper);
