Fix crash and modernize project

[grantland]

• Fixes crashes on new shield tv #67. Crash was due to assuming app icons were of BitmapDrawable while they could actually be AdaptiveIconDrawable now, so update to support all kinds of Drawables
• Modernize project just enough to work with modern gradle, but not enough to be able to be deployed on Google Play

[grantland]

To deploy on Google Play it requires targetSdkVersion 29, but 29 has a few breaking changes:

• Requires HTTPS, but can be worked around using android:usesCleartextTraffic="true"
• Intent.ACTION_INSTALL_PACKAGE is deprecated and requires using PackageInstaller

Hi grantland . Could you please generate an apk with your fix? Thanks.

[grantland]

@Rhylthus I don't have a compiled binary ready, but you should be able to run ./gradlew installDebug (OSX) to build your own

Will try to search. But I'm really a noob. Thanks!

Sadly i have some error when trying to build gradlew installOpencommunityDebug (wxindows). I have errors:

Execution failed for task ':app:processOpencommunityDebugGoogleServices'.

No matching client found for package name 'news.androidtv.tvapprepo'

Could you please help me. I would like to use your modificaiton in order to get it work on my Shield. Thanks !

@Rhylthus Have you tried using http://atvlauncher.trekgonewild.de/? This app really just does the same thing.
