[Q] Android How to make an app for different screen resolution

-5 down vote favorite
Hi I am new to android can someone help me to create an app for different resolution i am trying to develop an android app using imageview and textview. I am using the standard AVD (800) for testing. Now all the images seem dis-arrayed when i use it for other resolutions. I am wondering if the solution is through coding wherein my design will adjust itself to the screen size automatically? Please help me here.
Secondly, when i use the auto-rotate feature, again all image placings get dis-arrayed. I am also looking for solution that will allow my images to maintain the placings when rotated.
Please help me with some reference articles, readings or code explanation.
Thank you for your help.

[Q] Best Practices for Switching Between Fragments?

I'm wondering if I am doing Fragment navigation incorrectly. For the most part, my app is a series of full-screen fragments, and to get to the next one, I create a FragmentTransaction and then replace().
The problem is, occasionally, if I spam the screen with touch input, Fragments behind the current one will have onClick() called.
Is there something I need to do when replacing that I might have overlooked? How could views behind the Fragment I am looking at be recieving clicks?
What are the best practices for fragment switching/navigation?
(P.S. is this the best forum for this time op question?)
