SDK - R18 still has some bug

Question

Some jar libraries in the libs/ folder are not picked up in some cases.
Just like arcgis for Android sample project "HelloWord", compiled without problems, but can't run properly.

Answer 1

we might have encountered the same error - In my case the solution was to separate the Ant targets to two calls (ie "ant myParameters myTarget1 myTarget2", and "ant myParameters debug delivery"). Hope this works for you, anyhow - Google need to add better support for their undocumented/faulty changes (and stackoverflow isn't the best place for questions that are not originated in stupidity, as the lifetime of a complex question isn't too long here).

If that doesn't work for you please elaborate your question.
