					"body": "The plan is to first implement gradle support [TIMOB-19300] and then update the support libraries to rev 28 [TIMOB-26262], which is the last revision from Google that is not \"androidx\". Updating to rev 28 maintains backward compatibility and avoids having to recompile all modules.\r\n\r\nWe can't replace our support libraries with androidx libraries \"yet\" since that would break most modules and hyperloop users. Currently, everyone has hard-coded java imports to {{android.support.v4}}, {{android.support.v7}}, etc. and assumes Titanium includes those libraries. There will have to be a migration period. Google has a migration tool (such as jetifier) to help with this, but it is imperfect.\r\n_(This isn't trivial. Worst case scenario is a module that depends on a 3rd party pre-compiled JAR that depends on the \"old\" support libraries.)_\r\n\r\nOnce we have gradle support, you'll be able to reference the dependencies you want (such as androidx). The next challenge on our end is dealing with version conflicts such as the warning below. The below isn't unique to androidx. It'll happen if 2 libraries references 2 different revision of support libraries in general, such as between rev 27 and rev 28. (Gradle doesn't magically fix this.)\r\n{code}\r\nAll com.android.support libraries must use the exact same version specification\r\n{code}\r\n",
