Error while using android in eclipse

Question

I’m starting to learn to program with android and right away I came across this mistake, what to do?

Displays this error in the console:

Follow the error screenshot below:

Answer 1

as Caique Oliveira mentioned, if you’re starting with Android, use Android Studio. Because it’s supported by Google since last year, and incorporates the Gradle system to compile and manage your projects and libs.

What it seems to me is that you have two projects in Eclipse both with the same lib (android-support-v4.jar ) and are conflicting with each other.

Simple fix: remove one of the libs that should work. Fix better: install android studio and Gradle and you will no longer have these problems :)

Happy coding :D
