You need to <code>intent</code> your current <code>context</code> to another activity first with <code>startActivity</code>. After that you can <code>finish</code> your current <code>activity</code> from where you redirect.

<pre><code> Intent intent = new Intent(this, FirstActivity.class);// New activity
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 finish(); // Call once you redirect to another activity
</code></pre>

<code>intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)</code> - Clears the activity stack. If you don't want to clear the activity stack. PLease don't use that flag then.

It works of me when i navigate to home screen from splash activity

I have problems to finish the activity before. I want to start another activity and finish the current activity. When I used <code>finish</code> it didn't exit the current activity. 

How can I exit the activity before?

How to finish Activity when starting other activity in Android?

Kotlin

我在之前完成这项活动有问题。我想开始另一个活动并完成当前活动。当我使用finish时，它没有退出当前的活动。如何在此之前退出活动？
