急救中遇到的故障Android

發送第一條消息到helpshift之後，我收到了以下堆棧。我對android非常陌生，不明白如何調試。此外，這種崩潰發生在5倍，所以我不知道如何重現n修復它。急救中遇到的故障Android

發生此次崩潰的原因是調用發生在不包含關聯的活套的線程中。要停止此次崩潰：

創建處理程序線程。
使用上述處理程序線程的循環並創建一個註冊處理程序。
在註冊處理程序中進行API調用。

內，您的異步任務 -

@Override 
protected Void doInBackground(Void... voids) { 
    HandlerThread handlerThread = new HandlerThread("register-device-token"); 
    handlerThread.start(); 
    new RegisterDeviceTokenHandler(handlerThread.getLooper(), context).post(null); 
    return null; 
}

您註冊設備標記處理程序 -

private static class RegisterDeviceTokenHandler extends Handler { 

    private final Context context; 

    public RegisterDeviceTokenHandler(Looper looper, Context context) { 
     super(looper); 
     this.context = context; 
    } 

    @Override 
    public void handleMessage(Message msg) { 
     Helpshift.registerDeviceToken(context, "hello"); 
    } 
}
