We have two different kind of devices one is having soft back button, another one having hardware back button. Is there any common method for find out hardware back button is exists or not.

I tried the below code to detect hardware back button presence but that is not reliable. It is returning true for one tablet which don't have hardware back button and has soft back button.

boolean hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);

Please suggest me is there any way.

maybe try with ViewConfiguration.get(context).hasPermanentMenuKey(); – biegleux Oct 17 '14 at 10:58
@biegleux thanks for your response. I want to check back key not menu key. – Raghu Mudem Oct 17 '14 at 11:00
I suppose if a devices has a hardware menu key, it has back menu key as well, but I may be wrong. – biegleux Oct 17 '14 at 11:30
No that's not true always. Some devices has hardware back but not having hardware menu key. Instead of that multitasking key will present. – Raghu Mudem Oct 17 '14 at 11:36
