Communication change receiver gets false intent in android

Question

I am trying to add connection status information to my application. Using the examples here and the google documentation, you will get a receiver that correctly displays a warning when the connection status has changed, but also undesirable displays it whenever an action is created.

ConnectStatusReceiver:

package com.zivtaller.placefinder.receivers;

 import android.content.BroadcastReceiver;
 import android.content.Context;
 import android.content.Intent;
 import android.net.ConnectivityManager;
 import android.net.NetworkInfo;
 import android.util.Log;
 import android.widget.Toast;

  public class ConnectStatusReceiver extends BroadcastReceiver {

private String TAG = "netReceiver";

public ConnectStatusReceiver() {
    super();
}

@Override
public void onReceive(Context context, Intent arg1) {
    ConnectivityManager cm = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null
            && activeNetwork.isConnectedOrConnecting();
    if (isConnected) {
        Log.d(TAG, "Data connected");
        Toast.makeText(context, "Data connected", Toast.LENGTH_SHORT)
                .show();
    } else {
        Log.d(TAG, "Data not connected");
        Toast.makeText(context, "Data not connected", Toast.LENGTH_SHORT)
                .show();
    }

}

}

its initialization and registration in the onResume () action:

        netReceiver = new ConnectStatusReceiver();
    IntentFilter netFilter = new IntentFilter();
    netFilter.addAction("android.net.conn.CONNECTIVITY_CHANGE");
    registerReceiver(netReceiver, netFilter);

netReceiver = new ConnectStatusReceiver();
IntentFilter netFilter = new IntentFilter();

if (intent != null) {
    // broadcast is sticky
}

You are welcome,

unregisterReceiver(netReceiver);

In your method onPause().
