automated tests - Android black-box UI testing -

i have following problem: need test app blackbox app on different devices.

i've tried use monkeyrunner it, long change tap coordinates each device.

robotium , robolectric - useless cause need test app black box, , juint based.

uiautomatorviewer - useless too, because have specific android image without uiautomator on board. easiest solution it's add on device, can't it.

can me tool should use.

what need:
1) parse xml structure of apk.
2) able tap structure.
3) able copy data clipboard.
4) able take screenshots.

any appreciated.

i suggest go robotium. allow take screenshots. easy write testcases using robotium. provides solo class lots of functionality blackbox testing.
