Error :failed To Find Target With Hash String 'android-22'

i saw a few posts like in the past - but none of the answers worked for me(like this one : failed to find target with hash string 'android-22'). i got this probelm in my build.gran

Solution 1:

In SDK Manager, install API: 22 SDK platform.

From your screenshot, you have to scroll down a bit more to reach (API 22).
