Android phones for testing

I heard that for testing android application you have to test the开发者_运维技巧m on 2 different phones(depends of resolution) What phones are recommended?

I would also suggest testing on a device with 'pure' Android and at least one other with a third-party overlay like HTC Sense. Sense shouldn't get in the way, but if there is some sort of incompatibility for whatever reason then it's always best to know before you release!

For UI, Android emulators are fairly robust, You should set up all possible configurations based on the table listed here and test atleast once on all of them. That way you will have majority of UI issues address. After that you will need to ensure the correct API's are supported, so test on one handset having the target Android version.

Your best bet is a phone (Nexus S?) and a tablet if you want the most coverage. You can, however, use the emulator to emulate phones of varying screen sizes.
