android parse.com保存安装错误.找不到要更新的对象 [英] android parse.com saving installation error. object not found for update

问题描述

我在下面遇到此错误，不知道该怎么办.我什至不知道要在此处发布什么代码，因为我似乎无法找到代码中导致此错误的位置.还有一件重要的事情要提到:在我的第一个测试设备(运行HTC 4.0.4的HTC令人难以置信)上不会发生此错误，但是我的第二个测试设备(运行4.4.2的三星平板电脑)却收到此错误.

I'm getting this error below and have no idea what to do about it. I don't even know what code to post here because i can't seem to find where in my code is causing this error. There is one more important thing to mention: This error doesn't happen on my first test device which is a HTC incredible running android 4.0.4, but my second test device which is a samsung tablet running 4.4.2 does receive this error.

edit:我认为它与我的parse安装对象有关，因为它没有保存到第二台设备的数据库中.在我的代码中，我有:

edit: I think that it has something to do with my parse installation object, as it doesn't save into the database for the 2nd device. In my code I have:

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

它返回一个解析安装对象，该对象的对象ID不在数据库中.我尝试

And it returns a parse installation object with an object id that isn't in the database. I try to

 UserPushObj.saveInBackground();

，但不保存.有人可以指出我在正确的方法上可以解决该问题的方法吗?

but it doesn't save. Can someone point me on the right track as to what I can do to fix it?

推荐答案

通过删除其文件强制解析以重新初始化

Force Parse to reinitialize by removing its files

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Application类中使用它

use it in Application class

    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());
                }
            }
        }
    });
