EDIT:

this is the key 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);

EDIT2:

I have added the permission in my app:

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

but the error still the same.I ‘m wondering if it is caused by simulator,but I’m not sure.Could anyone help me please?the question has bothered me so much.

Thanks all your attention to my question ,I have solve the problem ,there is something wrong in emulator and I reset it all ,so it’s solve.

According to your stacktrace

java.lang.SecurityException: Access denied to process: 402, must have permission android.permission.SETWALLPAPERHINTS

You should add permission in manifest. Which is

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