Question

Est-ce que quelqu'un sait quel est le problème qui cause l'alerte incendie ne fonctionne pas quand entrer dans le rayon de proximité? J'ai lutté pendant une semaine pour résoudre ce problème et je serai très reconnaissant si quelqu'un peut m'aider sur cette question ou me donner un guide pour le compléter.

MainActivity.java

import android.location.LocationManager;

import android.content.Intent; 


public class MainActivity extends Activity { 

    private static final long POINT_RADIUS = 150; // in Meters 
    private static final long PROX_ALERT_EXPIRATION = -1; // will not expire 
    private static final String PROX_ALERT_INTENT = "com.example.myalert"; 
    private LocationManager locationManager; 
    double latitude = 2.81202, longitude = 101.75989; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

     Intent intent = new Intent(PROX_ALERT_INTENT); 
     PendingIntent proximityIntent = PendingIntent.getBroadcast(this, 0, intent, 0); 
     locationManager.addProximityAlert(latitude, longitude, POINT_RADIUS, PROX_ALERT_EXPIRATION, proximityIntent); 
    } 

}

Answer 1

vous avez pas encore le récepteur dans le manifeste, "ProximityReceiver" est pas un Activité mais un récepteur. Essayez quelque chose comme ça.

<receiver android:name="ProximityReceiver" > 
     <intent-filter> 
      <action android:name="com.example.myalert" /> 
     </intent-filter> 
    </receiver> 

Cheers.
