I have been away from using eclipse and android java programming for a few weeks due to unforseen circumstances. I opened up eclipse yesterday and was prompted to make a few updates and accepted. Now all of my programs/applications work and all are coming back with errors. Everything was fine when I left it a few weeks ago.
The main problem is R cannot be resolved to a variable but I have fixed that before in the past. Nothing seems to work, I have tried many solutions.
Is everyone having the same problem after updating to ADT 22 or is it just me?
Open SDK Manager and download & install the Android SDK Platform Build-Tools Kit.
