Summary:
* Makes running Android example simpler - APG 2.2.0 automatically downloads dependencies so long as the user has previously accepted the Android SDK License.
* APG 2.2.0 requires Gradle 2.14 or newer, so updated to latest.
* Added `buildOptions.abortOnError false` so the build doesn't report any lint issues - the sample is designed to show Infer working, not Android lint.
