各位大侠，我明明加了这权限。为什么还会报错。

是运行出错还是编译不过？好像是运行出错吧，没有fatal吗，用DDMS调试看下

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

根据这句，你需要在你的代码中添加一句权限：

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

缺少权限，需要加上<uses-permission android:name="android.permission.SET_WALLPAPER_HINTS"/>

private static final int WALLPAPER_SCREENS_SPAN = 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);
