Question

当我打扑医生时，我得到以下回应。

  public void onSensorChanged(SensorEvent event) {

    deltaX = Math.abs(lastX - event.values[0]);
    deltaY = Math.abs(lastY - event.values[1]);


    deltaX = deltaX * 10;
    deltaY = deltaY * 10;


    if(deltaX > 2 && deltaY > 2){
      sendMSG((int)deltaX +"&"+(int)deltaY +"\n");
      Log.d("Velocity", "X + Y Values :: " + deltaX + deltaY);

    }

  }

所以我跑了扑医生--android-licenses。接受许可证后，这是我的答复

尝试扑扑医生--android-licenses，并得到相同的响应

All SDK package licenses accepted

这是什么问题？

Answer 1

可以先安装Android Studio，然后再依次单击工具> SDK管理器> Android SDK> SDK平台并安装Platform android-28

如果问题解决了，那就好，否则做这个完成此操作后，打开代码编辑器的终端并输入flutter doctor --android-license，然后继续按“ y”接受许可证。
