From the pulse forums (http://www.poweredbypulse.com/forums/showthread.php?1586-MyEclipse-9.1-and-Android-Development-Toolkit)

Hi,
I'm trying to add new software from MyEclipse Configuration Center version 9.1 (which uses pulse) and I'm getting the following errors while trying to apply the changes:

Software being installed: MyEclipse 9 (Profile) 2.0.0.0000000007 (com.poweredbypulse.profile-1754732-rmb-2061609 2.0.0.0000000007)

I've tried to follow the recommendations I found on the forum related to Android + MyEclipse 7.5, but it isn't related.
Please Help!!!

Noam,

Sorry to hear you are running into this issue. I am able to replicate this issue. I shall investigate and get back to you on this.

Sorry for the inconvenience.

Noam,

There are issues with Android Development Toolkit on Eclipse 3.6. Since MyEclipse 9.1 is based on Eclipse 3.6, you see the same dependency issues. There are couple of workarounds listed here - http://stackoverflow.com/questions/8629294/android-plugin-install-problems-in-eclipse

I have followed below mentioned approach -
1. Downloaded archived update site for ADT from here - http://dl.google.com/android/ADT-15.0.0.zip
2. Unzip the same
3. Copy plugins and features to [MyEclipse 9.1 installation dir]/dropins
4. Restart MyEclipse IDE
5. On restart MyEclipse IDE shall prompt with the plugins and features added to MyEclipse profile
6. In case Android SDK is not already added, you would be prompted to add the same. Follow the instructions

Let me know how this works for you.
