如果最近打开了 LocationServices(GPS/WIFI/MOBILE DATA)，则会调用超时，但会在一些延迟后开始工作。Google api 客户端被创建，连接时被调用，但它不返回任何位置。

以下代码用于 onConnected 并构建 google API：-

受保护的同步无效 buildGoogleApiClient() {

LogConfig.logd(TAG, "buildGoogleApiClient()");
if(mGoogleApiClient == null) {
    mGoogleApiClient = new GoogleApiClient.Builder(mContext)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
}
else
{
}
mGoogleApiClient.connect();

}

公共无效 onConnected（捆绑包）{

LogConfig.logd(TAG,"onConnected");
//Check location permission if it is granted by user or not
int hasLocationAccessPermission = ContextCompat.checkSelfPermission(AnalyticsApplication.mContext, Manifest.permission.ACCESS_COARSE_LOCATION);
if (hasLocationAccessPermission == PackageManager.PERMISSION_GRANTED) {
    if (mIsGetLastLocationRequest) {
        mIsGetLastLocationRequest = false;
        LogConfig.logd(TAG, "last Location Request");
        try {
            Location loc = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
            if (loc != null) {
                LogConfig.logd(TAG, "GotGPSFix:onConnected::" + loc.getLatitude() + "::" + loc.getLongitude());
                updateLocation(loc);
            } else {
                if (mLocRequest == null) {
                    mLocRequest = new LocationRequest();
                }
                try {
                    mLocRequest.setPriority(LocationRequest.PRIORITY_LOW_POWER);
                    gpsTimeoutValue = TIMEOUT_COARSE_LOCATION_FIX;
                    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocRequest, this);
                    startGpsTimeoutListener();
                } catch (Exception exp) {
                    setChanged();
                    notifyObservers(LOCATION_RESULT_INVALID);
                    LogConfig.loge(TAG, "Exception: getLastLocation(): requestLocationUpdates" + exp);
                }
            }
        } catch (Exception e) {
            LogConfig.loge(TAG, "Exception: getLastLocation()" + e);
            if (mLocRequest == null) {
                mLocRequest = LocationRequest.create();
                mLocRequest = new LocationRequest();
            }
            try {
                mLocRequest.setPriority(LocationRequest.PRIORITY_LOW_POWER);
                gpsTimeoutValue = TIMEOUT_COARSE_LOCATION_FIX;
                LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocRequest, this);
                startGpsTimeoutListener();
            } catch (Exception exp) {
                setChanged();
                notifyObservers(LOCATION_RESULT_INVALID);
                LogConfig.loge(TAG, "Exception: getLastLocation(): requestLocationUpdates" + exp);
            }
        }
    }  else {
        LogConfig.logd(TAG, "Request for Fresh Location.");
        try {
            LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocRequest, this);
            startGpsTimeoutListener();
        } catch (Exception exp) {
            setChanged();
            notifyObservers(LOCATION_RESULT_TIMEOUT);
            LogConfig.loge(TAG, "Exception: Request for Fresh Location" + exp);
        }
    }
}
