WiFi etPower

Test si le smartphone est connecté au réseau :

 public class TestWifi {  
   public static boolean hasInternetConnection(Context ctx)  
   {  
     ConnectivityManager cm = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);  
     NetworkInfo wifiNetwork = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);  
     if (wifiNetwork != null && wifiNetwork.isConnected())  
     {  
       return true;  
     }  
     /*  
     NetworkInfo mobileNetwork = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);  
     if (mobileNetwork != null && mobileNetwork.isConnected())  
     {  
       return true;  
     }  
     NetworkInfo activeNetwork = cm.getActiveNetworkInfo();  
     if (activeNetwork != null && activeNetwork.isConnected())  
     {  
       return true;  
     }  
     */  
     return false;  
   }  
 }  

Rajouter les permissions dans le fichier Manifest :

Test si le smartphone est connecté à un chargeur ou à un port USB :

 public class PowerUtil {  
     public static boolean isPowered(Context context) {  
       Intent intent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));  
       int plugged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);  
       return plugged == BatteryManager.BATTERY_PLUGGED_AC || plugged == BatteryManager.BATTERY_PLUGGED_USB;  
     }  
   }
