无法在Parse

过去两个小时我一直试图解决这个问题。我已经执行了初始化推送通知所需的所有步骤，但是甚至无法接收测试通知。

在我的应用程序的仪表板上，我确实看到一个名为＆＃34; Installation＆＃34;的类，其中包含用户的对象ID。

如果我尝试向所有设备发送推送通知，它会显示在推送日志中，但设备上没有任何注册。

要解决此问题，我尝试在模拟器中卸载并重新安装应用程序，清理项目，重新启动android studio并以其他用户身份登录（当我发送测试通知时，另一台设备已在Installation类中注册） 。没有任何效果。我附上以下相关代码。 

public class MyApplicationName extends Application {
public static final String TAG = MyApplicationName.class.getSimpleName();

@Override
public void onCreate() {
    Parse.initialize(this, "-", "-");
    ParseInstallation.getCurrentInstallation().saveInBackground();
}

  //To register the installation to each user that logs in
public static void updateParseInstallation(ParseUser user) {
    ParseInstallation installation = ParseInstallation.getCurrentInstallation();
    installation.put(ParseConstants.KEY_USER_ID, user.getObjectId());
    installation.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {
            if (e!= null) {
                Log.d(TAG, e.getMessage());
            }
        }
    });
}

} 

public class LoginActivity extends Activity {

 // some code 

  if (e == null) {
                 // login success!
MyApplicationName.updateParseInstallation(user);

  // some other code

编辑

我添加了一些额外的代码来获取更多信息，我添加了以下代码，以及logcat的相关部分

public class MyApplicationName extends Application {
   //code for initializing parse and ParsePush

  //this static method will run everytime a user logs in
public static void updateParseInstallation(ParseUser user) {
    ParseInstallation installation = ParseInstallation.getCurrentInstallation();
    installation.put(ParseConstants.KEY_USER_ID, user.getObjectId());
    installation.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {
            if (e!= null) {
                Log.d(TAG, e.getMessage());

因此，只要用户登录，就会运行以下代码：      MyApplicationName.updateParseInstallation（用户）;

推送通知假设每次找到对手时都会运行：

protected void sendPushNotification() {
    ParseQuery<ParseInstallation> query = ParseInstallation.getQuery();
    query.whereMatches(ParseConstants.KEY_USER_ID, mOpponent.getObjectId());
    ParsePush push = new ParsePush();
    push.setQuery(query);
    push.setMessage(getString
            (R.string.opponent_found_notification,
                    ParseUser.getCurrentUser().getUsername()));
    push.sendInBackground(new SendCallback() {
        @Override
        public void done(ParseException e) {
            if (e != null) {
                Log.d(TAG, e.getMessage());

以下是logcat的有趣部分：

Ribbit是我在尝试推送当前应用程序之前正在练习发送推送通知的应用程序。我不知道为什么这个应用程序出现在日志中，但我怀疑这是推送通知无法正常工作的原因。我试着清理我的浏览器，重新启动android studio，但是我在log cat中得到了相同的消息。有人可以，请帮帮我吗？我已经在下面附上了整个日志猫，以防有人感兴趣。

请避免使用gradle并查看Receiver和Manifest Files。

查看this问题。这是我写的一个问题。复制我在问题中使用的代码，并按照接受的答案（也是我）的说明。

ParseApplication.java：

package your.package.name;

public class ParseApplication extends Application {

    @Override
    public void onCreate() {
        Parse.initialize(this, "", "");
    }
}
