Hi All, I am new to android programming and want to develop an application which is a multi screen application . I have 4 screens A,B,C,D . B is started by calling startactivity(intent_B) defined in class A button click and c is calling by startactivity(intent_C) defined in class B and so on. Now I want to navigate from screen D to A . A screen is already created . flow of screen should be A->B->C->D->A. How should i achieve this? Please help me ASAP... thanx..
