在解析中無法接收推送通知

Question

我一直在試圖弄清楚過去兩個小時;我已經執行了初始化推送通知所需的所有步驟，但我甚至無法收到測試通知。

在我的應用程序的儀表板上，我看到一個名爲「安裝」的類，其中包含用戶的對象ID。

如果我嘗試向所有設備發送推送通知，它會顯示在推送日誌中，但沒有任何設備上註冊。

爲了彌補這個問題，我嘗試卸載並在模擬器中重新安裝應用程序，清理項目，重新啓動android studio並以其他用戶身份登錄（當我發送測試通知時，另一個設備已在安裝類中註冊）。沒有任何工作。我附上了下面的相關代碼。

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

編輯

我添加了一些額外的代碼，以獲得更多的的形成，添加以下代碼，與所述的logcat的相關部分沿

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，一旦用戶登錄，下面的代碼運行： MyApplicationName.updateParseInstallation（用戶）;

推送通知是假設運行每次對手發現：

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()); 

這裏是logcat的有趣的部分：

Ribbit的是我在練習發送推送通知的應用在嘗試推送當前的應用程序之前。我不明白爲什麼這個應用程序顯示在日誌中，但我懷疑這是推送通知不起作用的原因。我試圖清理我的瀏覽器，重新啓動android studio，但我在日誌貓中得到相同的消息。有人可以請，請幫我在這裏？我附上了下面的整個日誌貓，以防有人感興趣。

Answer 1

這可以幫助你

http://www.androidhive.info/2015/06/android-push-notifications-using-parse-com/

只要避免gradle這個並看看接收器和清單的文件。

Answer 2

看看this的問題。這是我寫的一個問題。複製我在問題中使用的代碼，並按照接受的答案（也是由我）的說明進行操作。

ParseApplication.java：

package your.package.name; 

public class ParseApplication extends Application { 

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