Make sure you have Android SDK Build-Tools installed from the Android SDK Manager

Click this guy:

Then make sure the top three are all installed:

Answer 3

Ensure the code, resources and AndroidManifest.xml do not have any problem.

First, delete the R.java file. As soon as you delete, that file should be re-generated automatically if you have enabled automatic build ( Project->Build Automatically ).

If that doesn't work try to clean the project by clicking on Project->Clean .

If it still doesn't work then, confirm you have android sdk build tools installed. For this, open Android SDK Manager and ensure Android SDK Build-tools has the status of Installed .

Also confirm that the ADT is up-to-date. To update ADT, in eclipse go to: Help -> Check for updates . Select the necessary entries like: Android Development Tools and update them.

Hopefully one of these solutions will solve your problems :-).
