ADT failed to launch after updating Android SDK
Just trying to update Android Developer Tool(ADT) and Android SDK. After updated Android SDK to 22.6, ADT failed to launch:
So trying to update eclipse packages, but no updates were found.
Help->Install New Software... and browse the Android Developer Tools update, we actually can see version 22.6.1 of ADT, so trying to force reinstall it.
Failed to install software...
Solution
Download ADT 22.6.1 in zip file: http://dl.google.com/android/ADT-22.6.1.zip
Help->Install New Software...->Add...Archive... to install the zip file manually.
It fixed all problems.
