How to finish Activity when starting other activity in Android?

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

How can I exit the activity before?

Intent i = new Intent(this,NewLaunchingActivity.Class);
    i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); // Call Only, if you wants to clears the activity stack else ignore it. 
    startActivity(i);
    finish();

Add Intent Flag Intent.FLAG_ACTIVITY_CLEAR_TOP if you want to clear the activity stack else ignore it. Read more about this here.

The best - and simplest - solution might be this:

Intent intent = new Intent(this, OtherActivity.class);
startActivity(intent);
finishAndRemoveTask();

Documentation for finishAndRemoveTask():

Call this when your activity is done and should be closed and the task should be completely removed as a part of finishing the root activity of the task.

Is that what you're looking for?

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

 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

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

startActivity(new Intent(context, ListofProducts.class)
    .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
    .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK));

  1. Make your activity A in manifest file: launchMode = "singleInstance"
  2. When the user clicks new, do FirstActivity.fa.finish(); and call the new Intent.
  3. When the user clicks modify, call the new Intent or simply finish activity B.

For eg: you are using two activity, if you want to switch over from Activity A to Activity B

Simply give like this.

          Intent intent = new Intent(A.this, B.class);
         startActivity(intent);
         finish();
