Fatal Exception: java.lang.IllegalStateException GoogleApiClient is not connected yet
提问by Nima G
We have this crash in crashlytics, the weird thing is it happens in onConnected()callback when requesting location updates.
我们在 crashlytics 中有这个崩溃，奇怪的是它在onConnected()请求位置更新时发生在回调中。
Code:
代码：
abstract public class MainService_6_LocationClient extends MainService_5_DriverGpsLocationStoring
implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private LocationListener highAccuracyListener;
private GoogleApiClient googleApiClient;
private LocationRequest gpsRequest;
@Override
public void onCreate() {
super.onCreate();
lazyInit();
googleApiClient.connect();
}
@Override public void onConnected(Bundle bundle) {
Log.d(TAG, "onConnected");
lazyInit();
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, gpsRequest,
highAccuracyListener);
}
private void lazyInit() {
if (highAccuracyListener == null) {
highAccuracyListener = new HighAccuracyLocationListener();
}
if (googleApiClient == null) {
googleApiClient = new GoogleApiClient.Builder(this).addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}
if (gpsRequest == null) {
gpsRequest = new LocationRequest().setInterval(2000)
.setFastestInterval(1000)
.setSmallestDisplacement(0)
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
}
@Override public void onConnectionSuspended(int i) {
Log.w(TAG, "onConnectionSuspended");
lazyInit();
googleApiClient.reconnect();
}
@Override public void onConnectionFailed(ConnectionResult connectionResult) {
Log.e(TAG, "onConnectionFailed");
}
@Override public void onDestroy() {
Log.d(TAG, "onDestroy");
if (googleApiClient != null) {
if (googleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(googleApiClient,
highAccuracyListener);
googleApiClient.disconnect();
}
googleApiClient = null;
}
highAccuracyListener = null;
gpsRequest = null;
super.onDestroy();
}

Doesn't onConnected()imply GoogleApiClientis connected and ready to be used? How can I resolve this?
是否onConnected()意味着GoogleApiClient已连接并可以使用？我该如何解决这个问题？

There's an issue with your code here:
您的代码存在问题：
@Override public void onDestroy() {
Log.d(TAG, "onDestroy");
if (googleApiClient != null) {
if (googleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(googleApiClient,
highAccuracyListener);
googleApiClient.disconnect();
}
Simply clean it up a bit:
简单地清理一下：
@Override public void onDestroy() {
Log.d(TAG, "onDestroy");
if (googleApiClient != null) {
if (googleApiClient.isConnected()) {
maintain boolean;
new intent(pass.through.filter(widgetBank.css(openbridge.jar))
<access bridge.java>cascadeRunTime(true)
googleApiClient.disconnect();
if situation(positive) {
//Call on filter
return false
}

Try using com.google.android.gms.location.LocationClientinstead of GoogleApiClient. Note that the ConnectionCallbacksand OnConnectionFailedListenerinterfaces that you implement will be slightly different.
尝试使用com.google.android.gms.location.LocationClient代替GoogleApiClient. 请注意，您实现的ConnectionCallbacks和OnConnectionFailedListener接口会略有不同。
Here's a quick example:
这是一个快速示例：
class LocationHandler implements ConnectionCallbacks,
OnConnectionFailedListener, LocationListener {
private LocationClient client;
void getLocation(Context context) {
client = new LocationClient(context, this, this);
client.connect();
}
@Override
public void onConnected(Bundle connectionHint) {
LocationRequest request = LocationRequest.create();
request.setNumUpdates(1);
client.requestLocationUpdates(request, this);
client.unregisterConnectionCallbacks(this);
}
@Override
public void onDisconnected() { }
@Override
public void onConnectionFailed(ConnectionResult result) {
// handle connection failure
}
@Override
public void onLocationChanged(Location location) {
client.removeLocationUpdates(this);
client.disconnect();
// do stuff with the location
}
}

You should instantiate a client object in your Activity's onCreate(Bundle) method and then call connect() in onStart() and disconnect() in onStop(), regardless of the state.
无论状态如何，您都应该在 Activity 的 onCreate(Bundle) 方法中实例化一个客户端对象，然后在 onStart() 中调用 connect() 并在 onStop() 中调用 disconnect()。
The implementation of the GoogleApiClient appears designed for only a single instance. It's best to instantiate it only once in onCreate, then perform connections and disconnections using the single instance.
GoogleApiClient 的实现似乎只为单个实例设计。最好在 onCreate 中只实例化一次，然后使用单个实例执行连接和断开连接。

Maybe you should notice, GoogleApiClient.Builderhas a method setAccountName(). You should invoke this method with your Google account name. I have tried, and succeeded. I used the following code:
也许你应该注意到，GoogleApiClient.Builder有一个方法setAccountName()。您应该使用您的 Google 帐户名调用此方法。我试过了，成功了。我使用了以下代码：
if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.setAccountName("李江涛")
.build();
}
if (mLocationRequest == null) {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(10000);
mLocationRequest.setFastestInterval(5000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
