Cannot use with latest version of the sdk Mopub-4.3.0

If I replace the mopub-sdk-release.aar with mopub-sdk-4.3.0.aar shows a lot of warnings:

Hi, incase you havent figured this out, I found that the issue is related to mismatched JDK libraries. You need to target the right one to make these errors go away. On another note, did you get updated to latest MoPub sdk? I tried but have failed. Any help would be appreciated!
