Eclipse shows warnings below, it seems it has something with proguard. But my project can be signed in other computer, and I did signed it before! what’s wrong? how to fix it?
Note: there were 210 duplicate class definitions.
You should check if you need to specify additional program jars.
Warning: can’t write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [android-support-v4.jar:META-INF/MANIFEST.MF])

Solved. -injar is needed. @see: Why Eclipse Can't Write Resource
EDIT: FInally, I found: It is not compatible with Astrill(VPN), I force closed astrill process and problems gone.
