Eclipse ADT - Android 4.2.2 sample project contain hundreds of errors

Question

I'm a beginner in Android programming and trying to look at the sample projects, from the Eclipse ADT (v21.1.0) i'm choosing New Android Sample -> 4.2.2 -> and have 3 sample choices (Support4Demo,11Demo,...) each of them have 100+ errors

most errors are "cannot be resolved to type" errors and overriding errors

what am i doing wrong? I am using the latest eclipse and SDK (downloaded together)

Thanks :)

Answer 1

please check the version of SDK android which you work with it in the project , check the path of the SDK Android , and the version of the JDK . just only these option .

good luck

Answer 2

After searching i found that the latest revision (#12 from Feb 2013) of the Android Support Library doesn't contain some classes that it should have (FragmentTabHost, and a few more)

tried to delete and download again, and again it didn't contain the classes it should,

I found this link to the previous release (if you want a different release you can just change the number - 01,02...,09,10,11,12)

http://dl.google.com/android/repository/support_r11.zip

I replaced the support folder, copied the new (older) jar , and that solved all the problems.
