I have implemented a simple timer with CountDownTimer on my game and I need it to start ater a few seconds when the activity is started.

On my main activity's onCreate method, I call this:

playingTime();

Which is as follow

public void playingTime() {
    new CountDownTimer(30000, 1000) {

        public void onTick(long millisUntilFinished) {
            String elapsedTime = String.valueOf(millisUntilFinished / 1000);
            timer.setText(elapsedTime);
        }

        public void onFinish() {

            timer.setText(R.string.timer_game_over_text);

        }
    }.start();

}

The timer start normally but immediatelly as the activity is launched. I would like to set a delay before it get executed or if there is a better way to set timer in games. (Count down timer and nomal timer)

You can add delay using Handler like as below:

Handler handler = new Handler();
handler.postDelayed(new Runnable() {
  @Override
  public void run() {
    //Executed after YOUR_DELAY_IN_MILLIS
    playingTime()
  }
}, YOUR_DELAY_IN_MILLIS);

Put the code in your activity onCreate() method

Using the Timer and TimerTask Classes, is an example of using a timer to perform a task after a delay: import java.util.​Timer; import java.util.TimerTask; /** * Simple demo that uses java.util.Timer to  To configure a deadline for an activity: Locate the activity in your process for which you want to configure a deadline. From the Component Palette, from the Catch Events section, select Timer. Drop the timer event over the activity.

You can use the handler in onCreate() method as shown below and playingTime will be called after 1 second

 new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                playingTime();
            }
        }, 1000);

Android Game Recipes: A Problem-Solution Approach, Launching a New Activity public class MainActivity extends Activity { static int the game, you simply set the delay to 1 second to force launch the game Activity. Shortening the Delay Timer public class MainActivity extends Activity { static int​  Select the activity, and in the Text field, type "This is the start time." Add a Delay activity and connect it to the previously added activity. Select the activity, and in the Properties panel, in the Duration field, type 00:00:20. This is the 20 seconds delay that is going to be between the two logged messages. Add another Write Line activity and connect it to the previously added activity. In the Text field, type "Message delayed by 20 seconds.".

You can set a delay like this :

       new Handler().postDelayed(new Runnable(){
          @Override
          public void run() {
            // call method here
          }
      }, MY_DELAY_IN_MS);

Replace MY_DELAY_IN_MS with your own delay

The Delay Activity, This activity proves itself quite useful in projects that require good timing, such as waiting for a specific application to start or waiting for some information to be  During this time any further pressing of the push button has no impact on the timer as long as the output is active or until the timer has finished its delay operation. Two Step Sequential Timer The above circuit can be modified to produce a two step sequential delay generator.

The FLP Microsatellite Platform: Flight Operations Manual, The value of the Deployment Timer will be prescribed by the launch supplier to induce some delay between satellite separation and first mechanical activities. With the delay timer, you can postpone the shooting time after confirming to shoot for a few seconds. Put your Samsung S7 Edge or S8 Plus on the tripod and set the timer. Before the photo is taken, you can get in the picture. Now we are intended to show how to set the camera delay timer to take a photo Samsung Galaxy camera.

App startup time, It begins by explaining the internals of the launch process. Next, it discusses how to profile startup performance. Last, it describes some common start-time issues,​  All you have to do is to access SureLock Settings, set an Idle Timeout and specify an application to auto launch every time the device is idle for the specified time. Here is how you do it. 1.

Restrictions on starting activities from the background, layout hierarchies · Re-using layouts with <include/> · Delayed loading of views Note: For the purposes of starting activities, an app running a foreground service notifications include handling an incoming phone call or an active alarm clock. Apps running on Android 10 or higher can start activities only when one or  In Atmel Microcontrollers, there are simple delay functions such as __delay_ms() and __delay_us() found in utils\delay.h. I am using a Tiva™ C Series TM4C1294 development board, with a TM4C1294NCPDT microcontroller. However, I can't find any libraries to do similar delay functions. Will I have to write my own delay function?
