[android] 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?

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();

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?

Intent i = new Intent(this,Here is your first activity.Class);
    i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(i);
    finish();
