My Android Studio and Intellij crash after I upgraded to Yosemite, I thought I have to use Eclipse ADT for the reset of my day. :-(

But thanks Jonas Osc, I got it fixed, now it’s up and running.

To fix it:

1. Right click on the app from the Dock
2. Choose “Options” -> “Show in Finder”
3. Right click on the app in Finder
4. Choose “Show Package Contents”
5. Open file: Contents/Info.plist
6. Search for “JVMVersion”
7. Change the value in the to “1.7*”
8. Save it, and enjoy!
