Clearing the SharedPreference data after some specified time
I am using SharedPreference in my application. When application is started I am saving some data in it. I have one Activity on which I am performing all Fragment operations like adding, replacing etc. I need to remove that stored data from preference if I am not performing any actions in application i.e. application is idle for some time. How to detect that user is not performing some operations in app and remove data from preference after some specified time when app is stable?

You can achieve it by adding thread on your parent activity / anywheve in the app which you or your app can access without any object initialization.
Declare Handler
private Handler handlerClearPref;
Add inside onCreate()
handlerClearPref = new Handler();
handlerClearPref.postDelayed(runnableClearPref, 20000);
Add inside Activity class out out of onCreate Method
private Runnable runnableClearPref = new Runnable() {
@Override
public void run() {
// Code to clear your Shared Preference contents.
handlerCheckEventNotification.postDelayed(runnableClearPref, 20000);
}
};
Above code will clear your prefrence at every 20 second.
And if you want to stop this thread then you can use below code.
handlerClearPref.removeCallbacks(runnableClearPref);
