修改

这是关键代码：

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：

我已在我的应用中添加了权限：

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

但错误仍然相同。我想知道它是否是由模拟器引起的，但我不确定。有人可以帮我吗？这个问题让我非常困扰。

感谢您对我的问题的全部关注，我已经解决了问题，模拟器中出现了问题，我将其全部重置，所以它就解决了。

Answer 1

根据你的stacktrace

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

您应该在清单中添加权限。这是

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

Answer 2

您需要向清单添加SET_WALLPAPER_HINTS权限：

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

启动器，必须具有android.permission.SET_WALLPAPER_HINTS权限
