Finish() not working for Activity in Some Devices

Question

Here is my code

private fun startMainActivity() {
    startActivity(Intent(this, MainActivityTab::class.java))
    finish()
}

Working fine in all devices but my Samsung device. When I press the back button in the MainActivityTab activity, it takes me back to the previous activity.

How to make this work for all the devices?

Device: Samsung A30s

@Squti which activity code, the startActivity or the MainActivityTab activity? — johnrao07, Jan 19 '20 at 08:11
Your back pressed override, click listeners, and onCreate of both activities — Squti, Jan 19 '20 at 08:13
I don't have back pressed override, click listeners and onCreate has only business code — johnrao07, Jan 19 '20 at 08:39

You can use Intent flag like FLAG_ACTIVITY_CLEAR_TASK and FLAG_ACTIVITY_NEW_TASK to achieve this. Check below:

val intent = Intent(this, MainActivityTab::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_NEW_TASK)
startActivity(intent)

It will totally clears all previous activity(s) and start new activity

For transition use any one from below based on your requirement:

overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.slide_out_right)

Or

overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out)

It is working now, but the activity starts as if it is forced, can we make it a smooth transition? – johnrao07 Jan 19 '20 at 08:45
use `overridePendingTransition` after `startActivity`. Check my updated answer – Md. Asaduzzaman Jan 19 '20 at 09:23
