Android Unable To Execute Dex

I am beginning to work on an android app with a group that has already started. After installing the SDK, and running the emulator, I got these error when trying to run the code.

Solution 1:

Make sure you have updated your Eclipse trough Help->Check for updates and istall the latest updates and if you use Windows make sure to do this with administrator rights. If that doesn't work, you could also try this: https://stackoverflow.com/a/7884908/1084764

Solution 2:

Try deleting the android-support-v4.jar libs file in the project. And then cleaning your project. It worked for me.

Solution 3:

Add the following to eclise.ini:

-vm C:/Program Files/Java/jdk1.6.0_10/bin

Solution 4:

It is very simple, If you have added google-play-service library project. Then just Update it revision from SDK Manager.

Please verify it and let me know if any one not able to resolve it.
