在 Helpshift 中崩溃 Android

Crash In Helpshift Android

在向 helpshift 发送第一条消息后,我正在关注堆栈。我是 android 的新手,不明白如何调试它。此外,此崩溃发生率为五分之一,因此我不确定如何重现并修复它。

发生此崩溃是因为调用是从不包含关联循环程序的线程发生的。要停止此崩溃:

  1. 创建处理程序线程。
  2. 使用上述处理程序线程的循环器并创建一个注册处理程序。
  3. 在寄存器处理程序中进行 API 调用。

在你的异步任务中 -

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

您的注册设备令牌处理程序 -

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");
    }
}
