How do I ensure my android app will look the same on all android phones?

Question

Is there a truefire way to make sure my app will display the same on my Motorola Droid 2 as it will on other Androids?

I use nothing more than basic Linear Layouts, Image Views, Buttons etc - is there a good checklist to go by before I even think about launching an app?

Clipping issues, What SDK I should launch my app in, etc...?

Answer 1

Make sure you are following the guidelines for supporting multiple screen sizes.

You can use the emulator to experiment with the different possible screen sizes and densities, as described in that document under how to test your app.

Answer 2

You can make emulator of different screen sizes to check your application.

One thing make sure you don't use "px"(pixels) anywhere in your application, use dp instead of px.
