所以整整一天我都想知道为什么我的应用程序没有工作，特别是GPSTracker，上个月工作正常。但是突然它停了下来，在找不到任何办法之后我尝试在我的手机上重置工厂，它有效。但在我登录我的Google Play帐户后，它立即停止工作，是否有人知道这里发生了什么？是阻止我的位置服务还是什么？ 这是代码：
public class GPSTracker extends Service implements LocationListener {
private final Context context;
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
boolean canGetLocation = false;
Location location;
double latitude;
double longitude;
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 5;
private static final long MIN_TIME_BW_UPDATES = 5000;
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.context = context;
getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if(!isGPSEnabled && !isNetworkEnabled) {
} else {
this.canGetLocation = true;
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
if(isGPSEnabled) {
if(location == null) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,

}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return location;
}
