Всем добрый день. Стоит задача сделать плагин для PhoneGap который будет определять гео-позицию юзера. Делаю так:
HelloPlugin.java
| Код |
package com.chiffa.test
import org.apache.cordova.Config;
import org.apache.cordova.DroidGap;
import org.apache.cordova.GPSListener;
import org.apache.cordova.api.Plugin;
import org.apache.cordova.api.PluginResult;
import org.json.JSONArray;
import org.apache.cordova.*;
import android.util.Log;
import android.webkit.WebView;
import android.content.Context;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.location.Geocoder;
import android.os.Bundle;
@SuppressWarnings("deprecation")
public class HelloPlugin extends Plugin implements LocationListener {
public static MainActivity context = null;
public static final String NATIVE_ACTION_STRING="nativeAction";
public static final String SUCCESS_PARAMETER="success";
private String bestProvider;
private LocationManager lManager;
private Location currentBestLocation = null;
@Override
public PluginResult execute(String action, JSONArray data, String callbackId) {
//only perform the action if it is the one that should be invoked
if (NATIVE_ACTION_STRING.equals(action)) {
lManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
bestProvider = lManager.getBestProvider(criteria, false);
try {
lManager.requestLocationUpdates(bestProvider, 1000, 0, this);
}
catch (Exception e) {
e.printStackTrace();
}
Log.d("Plugin", "Plugin is ok");
return new PluginResult(PluginResult.Status.OK, "Yay, Success!!!");
}
return null;
}
public void onLocationChanged(Location location) {
Log.d("---", String.valueOf(location.getLatitude()));
}
public void onProviderDisabled(String provider) {
}
public void onProviderEnabled(String provider) {
}
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}

MainActivity.java
| Код |
package com.cff.travel;
import android.os.Bundle;
import org.apache.cordova.*;
import android.location.Geocoder;
import android.content.Context;
import android.location.Criteria;
public class MainActivity extends DroidGap {
LocationManager lManager;
private static String bestProvider;
@Override
public void onCreate(Bundle savedInstanceState) {
HelloPlugin.context = this;
super.onCreate(savedInstanceState);
// Set by <content src="index.html" /> in config.xml
super.loadUrl(Config.getStartUrl());
//super.loadUrl("file:///android_asset/www/index.html")
}
}

на строке вызова lManager.requestLocationUpdates(bestProvider, 1000, 0, this); бьет ошибки:

Вроде как все сделано, как описано в доках и примерах... Подскажите, что не так? Заранее благодарен за помощь!
