Now three... Hope this will be very useful for those who doing time intervals and web services. ServiceChecker.Java  import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class ServiceChecker extends BroadcastReceiver {     ShukranDbHelper dbHelper;     @Override     public void onReceive(Context context, Intent arg1) {         // Just calling your method Log.d("hey", "I'm alive");     } } In AndroidManifest.xml <receiver android:name=".service.DataChecker"></receiver> In your Activity, Just call this. Intent alarmIntent = new Intent(this, ServiceChecker.class); pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0); startAlarm(); public void startAlarm() {     manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);     int interval =600000; // 10 minute //10000     manager.setRepeating(AlarmManager.RTC_WAKEUP, System.current

Hello friends, Hope you already see this example in lot of websites and blogs. I'm also doing these, because hope my example might be easy and understandable. Let's go. Create the class: ConnectivityReceiver.Java public class ConnectivityReceiver extends BroadcastReceiver {     public static ConnectivityReceiverListener connectivityReceiverListener;     public ConnectivityReceiver() {         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 (connectivityReceiverListener != null) {             connectivityReceiverListener.onNetworkConnectionChanged(isConnected);         }     }     public static boole

Hi friends, Have a great day. Today we're going to look for touch events in fragment. Taps - If you gonna multiple tap to view or do something, this will be more helpful. Just implement TouchListener in your fragment like this, public class FirstFragment extends Fragment implements View.OnTouchListener Then     @Override     public boolean onTouch(View v, MotionEvent event) {         int eventaction = event.getAction();         if (eventaction == MotionEvent.ACTION_UP) {             //get system current milliseconds             long time = System.currentTimeMillis();             //if it is the first time, or if it has been more than 3 seconds since the first tap ( so it is like a new try), we reset everything             if (startMillis == 0 || (time - startMillis > 3000)) {                 startMillis = time;                 count = 1;             }             //it is not the first, and it has been  less than 3 seconds since the first             else { //
