this one helps. you can use ScheduledExecutorService to create such a timer. Then on every tick, you can open the app if you want, and show the button, or just show the button if the user open the app. documentation is available here.

Changing visibility in WPF with a timer

I wish did fix the issue. Either use the Dispatcher to marshall it back to the UI thread, or you might want to consider using an animation instead? It would be very straightforward to setup an timeline in Blend to do this entirely in XAML.

android set visibility of a button on timer

hope this fix your issue The problem is that you're not in the UI thread when you call okButton.setVisibility(View.VISIBLE);, since you create and run your own thread. What you have to do is get your button's handler and set the visibility through the UI thread that you get via the handler.
So instead of
okButton.getHandler().post(new Runnable() {
    public void run() {

Hope that helps Assuming your goal is to toggle the display of the buttons each time the timer goes off, you simply do:
- (void)onTick:(NSTimer *)timer {
    _Rateapp1.hidden = !_Rateapp1.hidden;
    _ratebomb.hidden = !_ratebomb.hidden;
    _ratelab1.hidden = !_ratelab1.hidden;
NSTimer *t = [NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(onTick:) userInfo:nil repeats:YES];

To fix this issue , You may want to use android.os.Handler instead.
public class ExampleActivity extends ActionBarActivity
    protected void onCreate(Bundle savedInstanceState)
        ImageView iv = (ImageView) findViewById(R.id.imageView);
        new Handler().postDelayed(new Runnable() {
                public void run() {
        }, 3000);

How to stop timer in timer task and re-enable a button after timer stops?

To fix the issue you can do I am trying to create an App with timer in it using service, however the timer works fine but there is a problem in my code when timer completed (comes to 0:0) my button should again re enable automatically but it stays on disabled state only, I tried a lot to re enable it but did not solved. So please see my code below and tell me what should I do to re enable it? I am new to services and android , any help will be appreciated , First, make your Intent an instance variable like-
private Button btn_start;
private TextView tv_timer;
private Intent intent_service;
intent_service = new Intent(getApplicationContext(), Timer_Service.class);

if (mpref.getBoolean("finish", false)) {
} else {

     btn_start.setEnabled(false);  // a change is here
mEditor.putBoolean("finish", false).commit();
startService(intent_service); // start the service
private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String str_time = intent.getStringExtra("time");

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String str_time = intent.getStringExtra("time");
        if (str_time.equals("00:00")) {
            stopService(intent_service); // stop service after work done

if (long_hours == 0){
    mEditor.putBoolean("finish", true).commit(); // a change is here
