Update Eclipse with Android development tools v. 23

Question

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

Answer 1

DO NOT DO THIS

Warning: Please see the comments below this answer. These steps have had a negative impact for many people.

1. Click Help / Install new software...
2. Click on What is "already installed" (as in picture below)
3. In the new window you can uninstall the old ADT (uninstall Android Development Tools, Android DDMS, Android Hierarchy Viewer, Android TraceView, Android Native Development Tools and Tracer for OpenGL ES)
4. Restart Eclipse
5. Then again click on Help / Install New Software
6. Choose ADT... Install

I hope it helps!
