gradle - Failed to resolve: com.android.support:appcompat-v7:28.0

Question

When I use com.android.support:appcompat-v7:28.+ in my project's build.gradle(module) it works without any error. But when I just use com.android.support:appcompat-v7:28, just without .+, it gives me an error:

Failed to resolve: com.android.support:appcompat-v7:28.0

Just without the .+ end of it. I added maven before but the result was the same. Any idea to solve it?

Answer 1

28.0.0 is the final version of support libraries. Android has migrated to AndroidX. To use the latest android libraries, Migrating to AndroidX

Edit: Versions 28.0.0-rc02 and 28.0.0 are now available.

I don't see any 28.0 version on Google Maven. Only 28.0.0-alpha1 and 28.0.0-alpha3. Just change it to either of those or how it was previously, i.e., with .+ which just means any version under 28 major release.

For an alpha appcompat release 28.+ makes more sense.
