Android Connect To Internet Event

Is there an event that tells me that the device has connected to the INTERNET (3G or wifi)? I need to start some requests only after the device connects to the INTERNET. The code n

Solution 1:

You can use a Broadcast receiver and wait for the action ConnectivityManager.CONNECTIVITY_ACTION

Here the doc

Ex:

broadcastReceiver = newBroadcastReceiver() {

                @OverridepublicvoidonReceive(Context context, Intent intent) {

                    ConnectivityManagerconnectivity= (ConnectivityManager) context
                            .getSystemService(Context.CONNECTIVITY_SERVICE);


                        NetworkInfo[] info = connectivity.getAllNetworkInfo();
                        //Play with the info about current network state


                    }

                }
            };

            intentFilter = newIntentFilter();
            intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
            registerReceiver(broadcastReceiver, intentFilter);

Solution 2:

Use a Broadcast receiver which will get called whenever the network state changes:

privateNetworkStateReceiver mNetSateReceiver = null;

privateclassNetworkStateReceiverextendsBroadcastReceiver
{
    @OverridepublicvoidonReceive( Context context, Intent intent )
    {
        // Check the network state to determine whether// we're connected or disconnected
    }
}

@OverridepublicvoidonCreate()
{
    registerReceiver( mNetSateReceiver, newIntentFilter(
        ConnectivityManager.CONNECTIVITY_ACTION ) );
}

@OverridepublicvoidonDestroy()
{
    save();
    unregisterReceiver( mNetSateReceiver );
}

onReceive will get called whenever the network state changes, and you can use the techniques detailed in the other answer to determine whether you're actually connected or not.

Solution 3:

Using this function you are able to know device have internet connected of not:

publicstaticbooleanconnectionCheck(final Context context)
{   
    boolean returnTemp=true;
    ConnectivityManagerconManager= (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfoi= conManager.getActiveNetworkInfo();
    if ((i == null)||(!i.isConnected())||(!i.isAvailable()))
    {
        AlertDialog.Builderdialog=newBuilder(context);
        dialog.setTitle("CONNECTION STATUS");
        dialog.setMessage("Failed");
        dialog.setCancelable(false);
        dialog.setPositiveButton("Ok",newDialogInterface.OnClickListener() {
            publicvoidonClick(DialogInterface dialog, int which) {
                WifiManagerwifiManager= (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
        wifiManager.setWifiEnabled(true);
        Toast.makeText(TennisAppActivity.mContext,"Wi-Fi On", Toast.LENGTH_LONG).show();
            }
        });
        dialog.show();
        returnfalse;
    }
    returntrue;`enter code here`
}

Solution 4:

publicstaticbooleancheckInternetConnection(Context context) {

    finalConnectivityManagermConnectivityManager= (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);

    finalNetworkInfonetInfo= mConnectivityManager.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnectedOrConnecting()) {
        returntrue;
    } elsereturnfalse;
}

Use this function, function will return true if internet is connected else false
