I tried a lot of things like importing the project again changing the project.properties file etc., I am not able to solve the issue

please help me out thanks in advance.

Answer 1

Modify the project.properties file, which has:

target=android-19

to

target=android-21

after changes above close project then open and clean

I'd like to comment but I'm too low on reputation. I run into the same issue once when changing my pc so I used to export the library from my old pc and imported that one into the new one afaik. You can give it a try but I can not guarantee that it works for you as well. You can use my exported library if you want to. Eventhough it doesn't make much sense, for some reason it worked for me after that. https://www.dropbox.com/s/ly9mhmlvthk15f9/Libraries.zip?dl=0
