How can I open my application when an user enters a zone that has wi-fi? Is this possible? Suppose my application is onPause() state (means My Device's homescreen). now when device connected with wifi. it will automatically open my application.

Answer 1

Try add broadcast receiver and listen network changes, when wi-fi connected start your activity. Something like this solution

public class ConnectivityReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

                ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
                NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
                NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
                if (((null != wifi)&&(wifi.isAvailable())) || ((null != mobile)&&(mobile.isAvailable()))){
                    Intent uplIntent = new Intent(context, YourActivity.class);
                    uplIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(uplIntent);
                }

    }
}

And add to manifest

    <receiver android:name=".receiver.ConnectivityReceiver">
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
        </intent-filter>
    </receiver>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
