My question is the following: at this moment, how many types of Android resolutions do exists? And what are its sizes given in pixels?
Example: one of then is the 240x320 (used in Galaxy 5).
Context: right now, I'm working with an app that calls different methods given different resolutions. It's not related with resolution-independent development, but with user-experience, given hes mobile type. I've searched a little bit but I could not found a "table" or a "list" with these informations.
Thanks in advance.
Read this article http://developer.android.com/guide/practices/screens_support.html
Resume: think about resolutions if they were random. It's unpredictable value. So, it's better to develop for different configurations (which are fixed), like small-medium-large screens or low-medium-hight dpi.
However, in the link below there a table that contains most of used resolutions http://developer.android.com/guide/practices/screens_support.html#testing
