Question: I built the SDK and when I tried to point the "SDK Location" for the "Android Preference" on Eclipse, I'd get "This Android SDK requires Android Developer Toolkit version 10.0.0 or above. Current version is 9.0.0.v201101191456-93220.
Please update ADT to the latest version."
Trying "Check for Updates" through Eclipse resulted in no update to be applied. Is ADT 10.0.0 available for me to download? Or was there a FAQ I missed about this?
Answer: The sdk requires that because plugin.prop that is in SDK/tools/lib. Edit it to make it accept 9.0.0 10.0.0 is the version in stabilization, but is not available publicly (you can build it manually but it's tricky and requires linux). 11.0.0 is being developed in the master branch.
