I've had the same problem with JTPL <http://jtpl.sf.net/>
The solution I've found (not the best solution, but a pretty quick and simple one) was to actually get the source code of the library and include it in the project. I.e. now I have the packages: com.android.vending.licensing; com.android.vending.licensing.util; com.myapp; com.myapp.activity; com.myapp.service; ... net.sf.jtpl; net.sourceforge.jtpl; It's apparent Android (or Eclipse?) doesn't like JARs very much. A note is that even with this solution (including the source code in your own project), Eclipse still won't be able to build your app. I do it from the command line using ant, which, yes, it's pretty rudimentary and slower than Eclipse. Eclipse has a very erratic behavior (3.5 and 3.6 as well).. it will sometimes build my app (after a clean project), but then I modify the source code a bit and it will start giving the "Conversion to Dalvik format failed with error 1" message. Other times it will give the error immediately after clean project. Have no idea what's going on. My bet is the ADT Plugin is messing up for some reason (BTW they released 8.0.1 like less than a day after releasing 8.0.0, to "fix bugs". I'd expect an 8.0.2 pretty soon...).
