Answer 1

You should open the project.properties file from android-support-v7-appcompat and change the target api level to target=android-21.

Don't forget to clean the workspace after that using Project --> Clean...

Answer 2

i do not know so i will just post this.. fyi: i have not specifically experienced this type of error, but more like it..

1 : delete the android-support-v4.jar in your project and copy the appcompat_v7 's rather

2 : Delete the all the files in the bin folder of the appcompat_v7 and clean and build and restart (if this doesn't work at the 1st instance, disable build automatically-[by clicking the project on your eclipse], and redo the no2 and save and restart eclipse, and build save, and restart..)

3 : right click on your appcompat_v7 project goto build path then configure build path then java build path and to the tab order and export and uncheck all the libs there the ones ending with .jar ... if you do not see .jar files then (uncheck android private libraries)(goes with the condition - that's a hard guess because on my project its checked)

4 : if you have other libraries then follow number 2(and 3) on them (3 is optional)

5 : if none of them are working check if there's some update on the adt or anything that can be updated

Always clean rebuild and restart eclipse okay.. Hope it helps
