Was it helpful?

Solution 3

ok i fixed it with the help of http://brettsdevblog.blogspot.com/2011/10/android-sdk-revision-13-pain.html it was all problems of android platform-tools which should have been updated

OTHER TIPS

you use the command to create the project android create project ..., may create a build.xml in your project, i think you don't need modify it, it work right.

Update android-tools and android-platform-tools using the android sdk manager.
