<p><strong>EDIT:</strong></p>

<p>this is the key code:</p>

<pre><code>private static final int WALLPAPERSCREENSSPAN = 1;
WallpaperManager wpm = (WallpaperManager) getSystemService(WALLPAPER_SERVICE);
    Display display = getWindowManager().getDefaultDisplay();

    final int width = display.getWidth();
    final int height = display.getHeight();

    wpm.suggestDesiredDimensions(width * WALLPAPER_SCREENS_SPAN, height);
</code></pre>

<p><strong>EDIT2:</strong></p>

<p>I have added the permission in my app:</p>

<pre><code>&lt;uses-permission android:name="android.permission.SET_WALLPAPER_HINTS"/&gt;
</code></pre>
