Я разрабатываю приложение с картой и публикую приложение на рынок. сейчас, у меня есть 2 аварии & ANRs от двух пользователей моего приложения. но для меня я отлично работаю! и у меня нет подсказки, в чем проблема ?! :( вот мой код и ошибка они получают:Моя карта Google api v2 сбой приложений
public class MapCurrentPlace2 implements LocationListener {
public Context context;
double latitude = 0;
double longitude = 0;
String placeName = "";
// then use below code
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
Location location = null;
boolean isGPSEnabled;
boolean isNetworkEnabled;
private boolean canGetLocation;
public MapCurrentPlace2(Context context) {
super();
this.context = context;
}
public Location getLocation() {
try {
LocationManager locationManager = (LocationManager) context.getSystemService(context.LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
// no network provider is enabled
} else {
this.canGetLocation = true;

locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER,MIN_TIME_BW_UPDATES,MIN_DISTANCE_CHANGE_FOR_UPDATES, (android.location.LocationListener) this);

Вот мой код version2 ... ** это хороший способ?! **

Спасибо всем я люблю этот сайт!
я попробовать ваши предложить, но то, что мне нужно делать в строке: ocationManager.requestLocationUpdates (LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, это); –
@ user3453502 не понимаю, что вы хотите сказать? – duggu
Я скопировать и вставить код, но строку: cpMIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES "является (cpMIN_TIME_BW_UPDATES не может быть разрешен к переменному) –
