编辑：

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:

我已在我的应用程序中添加权限：

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

但错误仍然是一样的。我想知道这是否是由模拟器引起的，但我不确定。有人能帮我吗？这个问题一直困扰着我

感谢大家对我的问题的关注，我已经解决了问题，emulator中出现了问题，我将其全部重置，因此问题得以解决。

您需要将

设置壁纸提示
权限添加到清单中：

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

根据您的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。那是

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


我已经添加了权限，但仍然存在错误我已经用我的密钥代码更新了问题，你能帮我吗？我已经添加了权限，但仍然存在错误是相同的错误吗？如果没有，请发布。是的，这是相同的错误，我已经用我的关键代码更新了问题，请帮助我。我已经解决了它。thanks@Dibya我已经更新了代码，谢谢
