Restart app from first activity

In my app I have the following sequence:

A->B->C

In C, there is a button which upon pressing should take me straight back to A. The problem is that after it goes back to A, upon pressing back it takes me to C then B then A and then finally exists.

What I want is that when the app goes from C to A, pressing back should exit the program (and not take me back to C)

Following code in A does not work:

    android:clearTaskOnLaunch="true"
    android:launchMode="singleTask"

Code to go back to A:startActivity(new Intent(trip.this, login.class));

Add the following code in your Activity A.

   public void onBackPressed(){
            Intent a = new Intent(Intent.ACTION_MAIN);
            a.addCategory(Intent.CATEGORY_HOME);
            a.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(a);

        }

Remove these two lines too. I don't think you need them.

android:clearTaskOnLaunch="true"
    android:launchMode="singleTask"

With that launchMode you can add the flag: FLAG_ACTIVITY_CLEAR_TOP to your intent to start the activity.

Upon pressing the button at C, you could finish() the Activities C and B.

activityC.finish();


activityB.finish();
