我想创建一个消息给GCM,每隔几秒发送一次。但一段时间后,我想再次删除locationupdates。为了将数据发送到gcm的intentservice,我使用了pendingintent。现在每次和它发生了很多我得到这个错误:Google API客户端错误,发送位置
产生的原因:
java.lang.IllegalStateException: GoogleApiClient is not connected yet.

这是我的代码:
public class LocationUpdate extends Service implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "DRIVER";
private SharedPreferences pref;
private String driverId;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
private Intent mGcmIntentService;
private PendingIntent mPendingIntent;
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e(TAG, "onStartCommand");
super.onStartCommand(intent, flags, startId);
boolean stopService = false;
if (intent != null)
stopService = intent.getBooleanExtra("stopservice", false);
if (stopService)
stopLocationUpdates();
return START_STICKY;
}
@Override
public void onCreate() {
Log.e(TAG, "onCreate");
pref = getSharedPreferences("driver_app", MODE_PRIVATE);
driverId = pref.getString("driver_id", "");
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
}
@Override
public void onDestroy() {
Log.e(TAG, "onDestroy");
super.onDestroy();
}
public void stopLocationUpdates() {
if(!mGoogleApiClient.isConnected()){
mGoogleApiClient.connect();
}
mGcmIntentService = new Intent(this,SendDataIntentService.class);
mGcmIntentService.putExtra("ID", "FusedLocation");
mPendingIntent = PendingIntent.getService(this, 0, mGcmIntentService, PendingIntent.FLAG_CANCEL_CURRENT);
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mPendingIntent);
if (mGoogleApiClient.isConnected())
mGoogleApiClient.disconnect();
}
@Override
public void onConnectionFailed(ConnectionResult arg0) {
// TODO Auto-generated method stub
}
@Override
public void onConnected(Bundle arg0) {
// TODO Auto-generated method stub
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
mLocationRequest.setInterval(30000);
startLocationUpdates();
}
private void startLocationUpdates() {
mGcmIntentService = new Intent(this,SendDataIntentService.class);
mGcmIntentService.putExtra("ID", "FusedLocation");
mPendingIntent = PendingIntent.getService(this, 0, mGcmIntentService, PendingIntent.FLAG_CANCEL_CURRENT);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, mPendingIntent);
}
@Override
public void onConnectionSuspended(int arg0) {
// TODO Auto-generated method stub
}
}
任何人都知道如何解决这个bug?或者如何解决它?我在网上搜索,但找不到任何东西。
我现在在打电话,所以看不到行号。但是在代码的第83行,客户端没有连接。看看阻塞,直到有一个连接(不要阻止UI线程虽然) –
你能更具体,我怎么才能检查,直到有一个连接?实现一个while循环?或者你能提出一个更好的解决方案吗? –
