Removing gradlew causes travis-ci to fail with wrong version of Gradle

[alan412]

The removal of gradlew causes travis-ci to fail. Don't know why it is needed by Travis or why it is no longer in 6.0

Hmm this does look like it was accidentally omitted

Migration damage.

@alan412 You want to give this branch a spin and see if fixes your travis-ci problem?

That fixes the missing gradlew problem. There is still the #4 issue (lint)

I am tempted to propose a simple .travis.yml file to go into the repo - then anyone that has their repo as a public repo in GitHub will get Travis-CI building on all commits "for free". (My team actually has master protected so you can't push to it and you can't do a pull request until Travis-CI has successfully built it. A little thing but it makes sure that the master branch always builds.)

Here is the simplest one that will work:

.travis.yml (put in root dir)

language: android
dist: trusty
android:
  components:
    - build-tools-29.0.2
    - android-28
