This is a very basic doubt. I have a MainActivity, and I created another Activity that is supposed to act as an transparent screen to the MainActivity. Thus, I want this 2nd Activity, say DisplayHelpActivity, to be shown first, when the app starts. Is the only way to change is to swap names and code, or is there another way to specify the order in which the activities should occur? Please help me. By the way, when the DisplayHelpActivity Transparent screen is on, I want the MainActivity to be shown in the background.

Change the type of the activities in the Manifest file,
For the Activity, you want to start first, declare its action the manifest file as,
and for the activity, you want to start next to first activity, declare its action in mainfest as,
and for the question you ask about having transparent dialogues, you can define the theme for the dialogue layout as tranparent or you can create your own theme for the dialogue..
