我在这里看了这个Q& A:GoogleApiClient is throwing "GoogleApiClient is not connected yet" AFTER onConnected function getting called
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,我仍然遇到同样的错误。
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 onResume() {
super.onResume();
if (!mGoogleApiClient.isConnected()) {
mGoogleApiClient.connect();
}
resumeLocationUpdates();
}
private void resumeLocationUpdates() {
Log.i("RESUMING", "RESUMING LOCATION UPDATES");
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, locationRequest, this);
}
这是记录器显示的内容,这让我感到困惑,因为它显示已连接但应用程序崩溃说没有连接......

您的问题出在onResume
逻辑:
@Override
protected void onResume() {
super.onResume();
if (!mGoogleApiClient.isConnected()) {
mGoogleApiClient.connect();
}
resumeLocationUpdates();
}
private void resumeLocationUpdates() {
Log.i("RESUMING", "RESUMING LOCATION UPDATES");
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, locationRequest, this);
}
对mGoogleApiClient.connect()
的调用是异步的。它在连接完成之前返回,并且您在连接客户端之前请求位置更新。您需要将requestLocationUpdates
调用移至GoogleApiClient.onConnected
回调。在此活动之后,您的客户端已连接。
@Override
protected void onResume() {
super.onResume();
if (!mGoogleApiClient.isConnected()) {
mGoogleApiClient.connect();
}
}
@Override
public void onConnected(Bundle bundle) {
resumeLocationUpdates();
}

您的课程必须实施GoogleApiClient.ConnectionCallbacks,GoogleApiClient.OnConnectionFailedListener,LocationListener并覆盖所有方法。
GoogleApiClient将与LocationServices通信,并为用户提供经度和纬度。
在您的OnCreate()方法中构建一个使用所需api的GoogleApiClient。
在onStart()方法中,开始连接GoogleApiClient。
在Sucessfull连接上调用OnConnected()方法,我们将在这里进行LocationRequest。
