@yaraki can you change it on the other samples as well?

And possibly update https://github.com/googlesamples/android-ndk/tree/master/builder or https://github.com/googlesamples/android-ndk/blob/master/.travis.yml to enforce it?

CLAs look good, thanks!

can you add something like this in .travis.yml for both compileSdkVersion and targetSdkVersion to ensure they remains the same when we update them in the future.

test $(echo $(grep -h compileSdkVersion */app/build.gradle  | uniq  | wc -l)) == "1"

rebase?
