So, I just finished building my first android app which supports API 14 and up, and works on any android OS 2.3.3 and up. My program works on all the emulators listed in the SDK. Does that mean that my program should be compatible with just about any android phone out there? Should I trust the sdk emulators? Please post your thoughts...

Thank you
Andy

it depends on your app. if it uses any hardware features then you should definitely test on device.

No, it does not use any hardware features.

theoretically yes but it depends on device firmware. When you are working with the emulator it has a defined configuration. but when you will work with devices, All the devices have different firmware. check out the internet connected condition is connected and connection. in some devices both will work like galaxy ace but it you will check the same condition in galaxy s2 is connectioned wouldn.t work.(either it or previous condition)
