Please i have different platforms installed. I just wanted to know what am supposed to do. If i develop with 3.0 platform, would those with a 2.2 be able to use my app??..
The second question which is the main question is I always get this error when i create android projects..
[2011-05-16 16:32:21 - Hello World] Dx no classfiles specified
[2011-05-16 16:32:21 - Hello World] Conversion to Dalvik format failed with error 1
What do I do to it?
There are several reports out there for that error (e.g., this one. All the solutions point simply to reload the project (select it in the tree at your left, and press F5).
Regarding the first question, unless you want to support Honeycomb-only features, then set up the api level to 8 (Froyo).
Eclair, Froyo and Gingerbread are android versions 2.1, 2.2 and 2.3 respectively (also referred in the documentation as API levels 7, 8 and 9). See the table here. If you want to support just mobile phones, set your target to 2.1 or even lower. That way you will be able to target most of the phones in the market. Your app will also run in Honeycomb (3.x) devices.
Honeycomb has new features to support larger screen devices, so if that is your main target, you might consider taking advantage of those features and drop cell phone support. All will depend on what is your objective.
