android parse.com正在保存安装错误。找不到要更新的对象

我在下面看到这个错误，不知道该怎么办。我甚至不知道在这里发布什么代码，因为我似乎找不到代码中导致此错误的地方。还有一件更重要的事情需要提及：这个错误不会发生在我的第一台测试设备上，这是一台运行安卓4.0.4的HTC Evaluable，但我的第二台测试设备是运行4.4.2的三星平板电脑，它确实收到了这个错误

编辑：我认为这与我的parse安装对象有关，因为它不会保存到第二台设备的数据库中。在我的代码中，我有：

 ParseInstallation UserPushObj = ParseInstallation.getCurrentInstallation();
 System.out.println(UserPushObj.getObjectId());

它返回一个parse安装对象，该对象的对象id不在数据库中。我试着

 UserPushObj.saveInBackground();

但这并不能节约。有人能给我指出正确的方向，我能做些什么来修复它吗

似乎Parse DB中不存在Parse安装。。。

因此，我找到的一个解决方案是卸载/安装应用程序。

通过删除其文件强制解析重新初始化

public static void removeCurrentInstallation(Context context) {
    File filesDir = context.getDir("Parse", Context.MODE_PRIVATE);
    boolean exists = filesDir.exists();
    File[] files = filesDir.listFiles();
    if (exists && filesDir.length() > 0) {
        for (File file : files) {
            if (file.isFile())
                file.delete();
        }
    }
}

在应用程序类中使用它

    ParseInstallation.getCurrentInstallation().saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {
            if (e == null) {
                Log.i("Parse", "Installation saved successfully");
            } else {
                Log.e("Parse", "Installation failed to save: " + e);
                if (e.getCode() == ParseException.OBJECT_NOT_FOUND) {
                    removeCurrentInstallation(getApplicationContext());
                }
            }
        }
    });

只需从您的设备或模拟器中删除应用程序并清理项目。然后再试一次。检查清单文件也应该很好。希望这有帮助。我遇到过同样的麻烦吗？你有什么办法吗？
