Question

I have following code snippet in my application activity.

If user is landing on activity for the first time then only thing that will happen is changing the boolean variable shouldSleep to true.

Thereafter, else part will be executed which contains generation of notification at every 60 seconds.

But the main problem is if I execute this code, the activity NEVER gets displayed as it keeps looping in else part and hence go on sleeping.

What I want is remaining application should run normally while every 60 seconds, else part of this method should be executed.
I guess it has got something to do with AsyncTask but I don’t have much idea about it.

Any idea how to do this? Thanks in advance for your help.

boolean shouldSleep=false;
private void ShowNotification() 
{
    //DO SOME TASK

    if (shouldSleep) 
    {
        Thread.sleep(60000);
        //DO SOME TASK
    } 

    else
   {
        shouldSleep = true;
   }

        /** Calling the method recursively so that it always runs. */
        ShowNotification();
}

Maybe you can use a Timer object :

new Timer().schedule(new TimerTask() {
    @Override
    public void run() {
        //This code is run all 60seconds
        myBooleanVar = true;
        //If you want to operate UI modifications, you must run ui stuff on UiThread.
        Activity.this.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Activity.this.changeUiStuff();
            }
        });
    }
}, 60000);
