TNS 5.x CLI doesn't support TNS 2 running

[NathanaelA]

Environment

• CLI: 5.3.1
• Cross-platform modules: 2.5.1
• Android Runtime: 3.01
• Plugin(s): (lots)

Describe the bug
Doing a tns run android actually does start the emulator, builds the apk; but never installs the apk nor does the watching/syncing work.
It displays:

  - Starting compilation in watch mode...
  - Found 0 errors. Watching for file changes.

So at this point the only way to update the APK with new code; is to manually kill the platforms/android folder; rebuild and then manually install it.

To Reproduce

1. Create a TNS 2.x app.
2. Run it with a modern CLI.

Expected behavior
Everything continues to work

Additional context
This might be something that could be considered a corner case; not sure how many people have to rebuild any older apps; so this might be a bug left just so people can find it.

@NathanaelA,

Thank you for reporting this issue!

We've deleted the support for android runtime version lower than 3.4.0 by mistake in our rc. The commit is reverted, so with the latest rc version of the CLI it should work as expected.

As of NativeScript 6.0.0 release, we'll drop officially the support for android runtime version lower than 4.2.0. It seems like the perfect time to migrate to newer android runtime version 😄.

Just a FYI; I tried 5.3.2-2019-04-12-13150 and it still did the exact same thing. I'll try the RC tomorrow to see if it shows up and maybe missed the window today...
