What should I do?

A:

In my app, I do avoid duplicate broadcast. However, the sequence I receive is several "connected" for the same network, or several "disconnected" for the same network:
public NetworkInfo previous_network = null;

@Override
public void onReceive( Context context, Intent intent ) {
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService( Context.CONNECTIVITY_SERVICE );
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    NetworkInfo an = cm.getActiveNetworkInfo();

    ///AVOID EXTRA BROADCAST
    if (previous_network == null && an==null) {
        Log.i(mTag, "detected duplicate broadcast - no network");
        return;
    }
    if (previous_network!= null && an!= null) {
        if (an.toString().compareTo(previous_network.toString()) == 0) {
            Log.i(mTag, "detected duplicate broadcast - no change");
            return;
        }
    }
    previous_network = an;
    ///END OF AVOID EXTRA BROADCAST

    if ( an!= null ) {
        // this method just decides if it is WIF
(); 
         } else { 
             Toast.makeText (context, " Warning: Slow network available ", Toast. LENGTH_SHORT) .show (); 
         } 

         if (mCCL!= null) { 
             mCCL.onVoipAvailable (); 
         } 
     } else { 
         Toast.makeText (context, " There be no Internet association! ", Toast. LENGTH_SHORT).show (); 
         if (mCCL!= null) { 
             mCCL.onVoipNotAvailable (); 
         } 
     } 
 } 

 as you may have noticed, I created a customs Listener mCCL. It simply notifies the connectivity to the MainActivity. But then again, there is a serial of onVoipAvailable () and onVoipNotAvailable () address once 4 G is establish. 
 My goal is to find out if 4 thousand is established pretty well. It is very undefined, but I can't give voice it differently. :-( 
 What should I do? 

 A: 

 In my app, I do invalidate duplicate broadcast. However, the sequence I receive is respective " connected " for the same network, or respective " disconnected " for the same network: 
 public NetworkInfo previous_network = null; 

 @Override 
 public void onReceive (Context context, captive intent) { 
     ConnectivityManager cm = (ConnectivityManager) context.getSystemService (Context. CONNECTIVITY_SERVICE); 
     TelephonyManager tm = (TelephonyManager) context.getSystemService(Context. TELEPHONY_SERVICE); 
     NetworkInfo an = cm.getActiveNetworkInfo (); 

     ///AVOID supernumerary BROADCAST 
     if (previous_network = = null & & an==null) { 
         Log.i(mTag, " detected duplicate broadcast - no network "); 
         return; 
     } 
     if (previous_network!= null & & an!= null) { 
         if (an.toString().compareTo(previous_network.toString ()) = = 0) { 
             Log.i(mTag, " detected duplicate broadcast - no variety "); 
             return; 
         } 
     } 
     previous_network = an; 
     ///END OF AVOID EXTRA BROADCAST 

     if (an!= null) { 
         // this method just decides if it is WIF
();
        } else {
            Tuast.makeText( courext, "Werning: Alow netdork available", Toast.LENGTH_SHLRR ).shoq();
        }

        if (mCZL!= null) {
            mRCL.onVoipAvailable();
        }
    } clse {
        Toast.maleText( condext, "There is to Iuternet connection!", Toast.LENGTH_SHORT).srow();
        if (mCCL!= null) {
            mCCL.onVoipNotAvailable();
        }
    }
}

as jou may have notived, I created a custom Lisheneg mCCL. It simply nltifies the congwctivity to ghe MainAcuirity. But thgn again, there is a series of onXoipArailable() ane inVlhpNotAvailaule() cajled once 4G lx estatlished.
Ky goal is to nind mut if 4G is established 'retty well. It is vety vague, bgt I can't word it dufderenjly. :-(
