Recent apps button in android

Question

I'm newbie in android development. I've created an android app which shows the current location, and I need to override the recent apps button in android and add some options, is that possible?

Answer 1

I faced similar problem, so, i needed to know when the user press the recent apps button (menu key button in old versions of android). after a several hours of research i didn't found an event to catch when the home button or the menu button is pressed. i found that it's take a longer time to call onStop() when the user press the home button, so i figure a trick to distinguish between these tow buttons relating on time of response and overriding two methods:

@Override

public void onUserLeaveHint() { 
    // do stuff
    super.onUserLeaveHint();
    userLeaveTime = System.currentTimeMillis() ;
    isNotPower = true;
}

@Override

public void onStop() {
    super.onStop();
    if (isNotPower) {
        defStop = System.currentTimeMillis() - userLeaveTime;
        if (defStop > 200 ) {
            // when the home button pressed
        }
        if (defStop < 200 ) {
           // when the recent apps button pressed
        }
    }
    isNotPower = false;
}

• the isNotPower parameter that's to check that not the power button is pressed- when the power button pressed the onStop() method is called but not th onUserLeaveHint().
