I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:
This Android SDK requires Android Developer Toolk
If Eclipse gives an error after uninstalling the ADT plugin from your Eclipse installation, try to edit file config.ini in the Eclipse folder → configuration. Find:
config.ini
eclipse.application=
And change it to:
eclipse.application=org.eclipse.ui.ide.workbench
I hope it works for you too.
