在我的应用程序IM通过此功能，让手机的位置，但是当我重启手机，启动应用程序，我得到这个方法无效。 是不是有什么，即时通讯丢失或做错了什么？ 我应该怎么做才能解决这个问题？
下面是使用功能的IM：
public void getAddress() {
Log.v("--", "get address 1");
boolean isGPSProviderEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean network_enabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
Log.v("--", "get address 31 " + isGPSProviderEnabled + " gps - "
+ isConnectedToNetwork());
if (isGPSProviderEnabled || network_enabled) {
Log.v("--", "get address 2");
Criteria c = new Criteria();
Log.v("--", "provider " + locationManager.getBestProvider(c, true));
locationManager.requestSingleUpdate(
locationManager.getBestProvider(c, true),
mLocationListener, Looper.myLooper());
location = locationManager.getLastKnownLocation(locationManager
.getBestProvider(c, true));
if (location == null) {
Log.v("--", "get address 6");
// TODO check if this is working
locationManager.requestSingleUpdate(
locationManager.getBestProvider(c, true),
mLocationListener, Looper.myLooper());
locationManager.requestLocationUpdates(
locationManager.getBestProvider(c, true), 0, 0,
mLocationListener);
Location oldLocation = new Location("");
oldLocation.setLatitude(new Double(prefs.getString(
Constants.LATITUDE, "48.51")));
oldLocation.setLongitude(new Double(prefs.getString(
Constants.LONGITUDE, "2.20")));
populateList(oldLocation);
// locationManager.requestLocationUpdates(
// locationManager.getBestProvider(c, true), 1000, 100,
// mLocationListener);
} else {
Log.v("--", "get address 3");
if (isConnectedToNetwork()) {
new AsyncTask<Void, Void, Void>() {
protected Void doInBackground(Void... params) {
try {
com.quanticapps.athan.utils.Geocoder geocoder = new com.quanticapps.athan.utils.Geocoder(
Main.this);
GeocoderModel geocoderModel = geocoder
.getFromLocation(
location.getLatitude(),
location.getLongitude(), 5);
city = geocoderModel.getCity();
country = geocoderModel.getCountry();
prefs.edit().putString(Constants.CITY, city)
.apply();
Log.v("--", "get address 4");
} catch (IOException e) {
Log.v("--", "get address 11");
e.printStackTrace();
} catch (LimitExceededException e) {
Log.v("--", "get address 12");
e.printStackTrace();
}
return null;
};
protected void onPostExecute(Void result) {
prefs.edit().putString(Constants.COUNTRY, country)
.apply();
prefs.edit().putString(Constants.CITY, city)
.apply();
populateList(location);
};
}.execute();
} else {
city = null;
Log.v("--", "get address 33 " + location.getLatitude());
populateList(location);
}
}
} else {
Log.v("--", "get address 5");
startGpsEnableDialog();
}
}
我的位置监听器：
private final LocationListener mLocationListener = new LocationListener() {
@Override
public void onLocationChanged(final Location location) {
// TODO
Log.v("--", "get address 121");
if (location != null) {
Main.this.location = location;
getAddress();
}
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
Log.v("--", "provider enabled");
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
Log.v("--", "provider disabled");
}
};
