我正在开发一个将内容投射到Chromecast的Android应用程序.有时在我com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks的onConnected方法实现中,我得到了一个

java.lang.IllegalStateException: GoogleApiClient is not connected yet.

例外.

这是堆栈跟踪:

我在这里查看了这个问答:GoogleApiClient正在抛出"GoogleApiClient尚未连接"之后onConnected函数被调用

因为它似乎与我所经历的相似,但事实并非如此.该用户的问题是他们在onStart()方法中声明了他们的api客户端,我在onCreate()方法中创建了我的答案.然而,我仍然得到同样的错误.

以下是我对这三种方法的代码:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    /* Butter knife creates the variables */
    ButterKnife.bind(this);

    /* Startup location services */
    locationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(10 * 1000)        // 10 seconds, in milliseconds
            .setFastestInterval(1 * 1000); // 1 second, in milliseconds

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();

    progressBar.setVisibility(View.INVISIBLE);

    refreshImageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getForecast();
        }
    });
}

@Override
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
    Log.i("Connected!!!", "WERE CONNECTED");
}

@Override
protected void …
