我们有这个崩溃crashlytics，奇怪的是它发生在 onConnected（）回调请求位置更新时。

We have this crash in crashlytics, the weird thing is it happens in onConnected() callback when requesting location updates.

code：

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();
  }

崩溃日志：

不 onConnected（）暗示的 GoogleApiClient 连接，并随时可以使用？我怎样才能解决这个问题？

Doesn't onConnected() imply GoogleApiClient is connected and ready to be used? How can I resolve this?

推荐答案

https://developer.android.com/reference/com/google/android/gms/common/api/GoogleApiClient.html

您应该在活动的onCreate（Bundle）来实例化一个客户端对象，然后调用connect（）的调用onStart（）和断开的onStop（）（），无论状态如何。

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.

在GoogleApiClient的实施似乎专为只有一个实例。这是最好的实例只在一次的onCreate，然后执行使用单个实例连接和断开。

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.
