Answer 1

You can remove an Activity from Stack by adding android:noHistory="true" attribute in AndroidManifest.xml

    <activity android:name="CurrentActivity" 
              android:launchMode="singleInstance" 
              android:noHistory="true" />

or by code:

Intent intent = new Intent(CurrentActivity_A.this,CurrentActivity_C.class); 
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.startActivity(intent);
