所以，我有一个在后台被调用的 JobService。但是我需要它来获取当前位置并将其发送到网络服务。当我发送静态数据时，Web 服务运行良好。然而，获得位置是一个问题。位置对象始终为空。这是我一直在尝试的。
public class GPSBackgroundJobService extends JobService implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private String LOGSERVICE = "GPS";
private InspectorsLogic mInspectorsLogic;
ParsoContext mContext;
private GoogleApiClient mGoogleApiClient;
ParsoLocationListener mLocationListener;
Location mLastLocation;
Double longitude;
Double latitude;
@Override
public void onCreate() {
super.onCreate();
Log.i(LOGSERVICE, "onCreate");
mContext = (ParsoContext) getApplicationContext();
mInspectorsLogic = new InspectorsLogic(mContext);
if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
}
@Override
public boolean onStartJob(JobParameters job) {
Log.i(LOGSERVICE, "onStartJob called");
mGoogleApiClient.connect();
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation!=null) {
latitude = mLastLocation.getLatitude();
longitude =mLastLocation.getLongitude();
sendGPSTask mSendGPSTask = new sendGPSTask();
mSendGPSTask.execute(Double.toString(latitude), Double.toString(longitude));
}else{
Log.e(LOGSERVICE, "Lat and Long are null");
}
return false;
}
@Override
public boolean onStopJob(JobParameters job) {
mGoogleApiClient.disconnect();
return false;
}
@Override
public void onConnected(Bundle connectionHint) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
}
