GoogleApiClient 无法连接

Question

我想使用 FusedLocationProviderApi 来获取最后一个已知位置。我按照谷歌教程所说的那样做，但似乎 GoogleApiClient 没有连接，至少它没有触发 onConnected 或 onConnectionFailed 方法。我希望你能帮助我，提前谢谢。

}

@Override

    System.out.println("check1?");
    Location mLastLocation;
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
            mGoogleApiClient);
    if (mLastLocation != null) {
        if(mLastLocation.getAccuracy() > 100){
            Toast.makeText(getApplicationContext(), "Für bessere Ergebnisse GPS anmachen", Toast.LENGTH_LONG).show();
        }
        Intent ServiceIntent = new Intent(getApplicationContext(),
                SendeAnfrageService.class);
        ServiceIntent.putExtra("LATITUDE", mLastLocation.getLatitude());
        ServiceIntent.putExtra("LONGITUDE", mLastLocation.getLongitude());
        startService(ServiceIntent); 
        System.out.println("check2?");
    }else{
        Toast.makeText(getApplicationContext(), "Probleme beim laden der Orte. Versuche es bitte nocheinmal", Toast.LENGTH_LONG).show();
    }

}

@Override
public void onConnectionSuspended(int arg0) {
    // TODO Auto-generated method stub

}
