I just updated my Android SDK to version 1.5. It was so easy, but there is a problem with generating new R.java in Eclipse under Linux. Guess why: android sdk is distributed in .zip packages, so there are no file mode bits setted. So under tools/ directory you need to chmod +x android-sdk/tools/* and also under each platform – chmod +x android-sdk/platforms/android-*/tools/* . Now it should works correctly. If not, simply remove gen directory from your project and do Clear project…
