Gpsを再起動できません

Question

私はアプリケーションを開始するGps location.whenを停止して起動しようとしています。私のブロードキャスト受信機でGpsを停止し、再度起動する必要があります.GPSは停止していません誰でも助けてください。

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    latituteField = (TextView) findViewById(R.id.TextView02); 
    longitudeField = (TextView) findViewById(R.id.TextView04); 
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    // Define the criteria how to select the locatioin provider -> use 
    // default 
    Criteria criteria = new Criteria(); 
    Log.i("ConnTest",locationManager.toString()); 
provider = locationManager.getBestProvider(criteria, false); 
Location location = locationManager.getLastKnownLocation(provider); 

// Initialize the location fields 
if (location != null) { 
    System.out.println("Provider " + provider + " has been selected."); 
    float lat = (float) (location.getLatitude()); 
    float lng = (float) (location.getLongitude()); 
    latituteField.setText(String.valueOf(lat)); 
    longitudeField.setText(String.valueOf(lng)); 
    final double a=(int) (location.getLatitude() * 1E6); 
final double b=(int) (location.getLongitude() * 1E6); 
str = Double.toString(a); 
str2=Double.toString(b); 

} else { 
    latituteField.setText("provider not available"); 
    longitudeField.setText("provider not available"); 
} 

    txtNetworkInfo = (TextView)findViewById(R.id.txtNetworkInfo); 

    receiver = new ConnectivityReceiver(); 

      registerReceiver(receiver,new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));

onPause（）が呼び出されたときに更新を無効にする必要があります。あなたが戻ってあなたのGPSが無効になっていない？ GPSを使用している別のアプリやサービスが実行されているのでしょうか？
