我正在开发需要特殊权限的系统应用程序。由于某些原因，我无法获得权限CLEAR_APP_USER_DATA，但可以使用INSTALL_PACKAGES，DELETE_PACKAGES等。是什么原因造成的？
显现:
uses-permission android:name="android.permission.CLEAR_APP_USER_DATA"/>
uses-permission android:name="android.permission.CLEAR_APP_CACHE"/>
uses-permission android:name="android.permission.INSTALL_PACKAGES"/>
uses-permission android:name="android.permission.DELETE_PACKAGES"/>
uses-permission android:name="android.permission.CHANGE_CONFIGURATION"/>
uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
我删除了“
我的使用权限的代码:
String apkPackage = intent.getExtras().getString(context.getString(R.string.key_package));
if (apkPackage != null) {
PackageManager pm = context.getPackageManager();
Class<?>[] types = new Class[] {String.class, IPackageDataObserver.class};
try {
Method methodClearUserData = pm.getClass().getMethod("clearApplicationUserData", types);
methodClearUserData.invoke(pm, new Object[] {apkPackage, null});
Method methodDeleteCache = pm.getClass().getMethod("deleteApplicationCacheFiles", types);
methodDeleteCache.invoke(pm, new Object[] {apkPackage, null});
} catch (NoSuchMethodException | IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
Log.w(TAG, "Unable to invoke clear method.", e);
}
} else {
Log.w(TAG, "Provided APK package is null.");
}

最佳答案
更改设备中的设置，即可正常运行。
启用开发人员选项的方式与我们有一个选项(USB调试(安全设置))的方式相同，因此将其打开。
在不同的设备中，选项可能会有所不同。
例如:Redmi Note 5 Pro-您可以在设置->其他设置->开发人员选项-> USB调试中找到
