Seems like a problem in SDK tools revision 22,
Download the new revision 22.0.1
Fixed a problem with DDMS monitor not opening heap and network statistics views due to a class not found exception. (Issue 55394)
Question
I once had this working but now the DDMS networks tab is completely empty. I tried 3 different devices (one even rooted), they have an ADB connection, everything else works. No luck. What could I be missing?
