Press the home button! you're done!

You need not really think about exiting the application(assuming you're asking for a exit button). This is not how Android apps usually work.

Please read upon this link for more information : When to Include an Exit Button in Android Apps (Hint: Never)

and this question also might be helpful.

@user179777 if you want to go that way, use `android:noHistory="true"` in the manifest for all your activities :) and `finish()` your current activity ..youre done! :) – COD3BOY May 30 '12 at 07:35
and also i want the back button in android to be work if i put this the back button will be working ? – Jagan May 30 '12 at 08:16
@user179777 umm I dont get you completeley.the back key will work fine and if want to do something when user presses the back key, you should be overriding `onBackPressed ()` method .. – COD3BOY May 30 '12 at 08:27

used this in your coding in your program

android.os.Process.killProcess(android.os.Process.myPid());

this will kill your process

When you start an activity, use startActivityForResult().

Intent intent = new Intent(MainActivity.this, NewActivity.class);
startActivityForResult(intent, ActivitiesRequests.REQUEST_FROM_NEW_ACTIVITY);

Then, if an activity wants to signal its caller to exit as well, it can use a result code: setResult(RESULT_CANCELED);. It is then caught in the MainActivity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    switch (requestCode)
    {
    case ActivitiesRequests.REQUEST_FROM_NEW_ACTIVITY:
        if (resultCode == RESULT_CANCELED)
            finish();
        break;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

can u give some example for this plz – Jagan May 30 '12 at 07:25 — Jagan, May 30 '12 at 07:25
