We are working on a Kotlin-based Android project where sentry is already up and running.
We would like to make use of the sentry [environment](https://docs.sentry.io/product/sentry-basics/environments/) tags in order to be able to distinguish between *production* and *staging* issues.

What I already know is:

1. It is possible to set a tag [programmatically](https://github.com/getsentry/sentry-java/issues/596). However, this is not what we are after.
2. It is possible to achieve [via the sentry-cli](https://github.com/getsentry/sentry-java/pull/440). However, this is not what we are after either.
3. It should be possible to use the *sentry.properties* file to configure the different environment tags. But I couldn't figure out: [which keywords](https://github.com/getsentry/sentry-java/issues/437) to use? [Where in the project structure](https://github.com/getsentry/sentry-react-native/issues/157) to place the [different](https://github.com/getsentry/sentry-java/issues/716) sentry.properties [files](https://github.com/getsentry/sentry-java/issues/671)?
4. By looking at the javascript documentation, I suspect there should be a way to achieve it via the AndroidManifest.xml. Has anyone managed to get it working like this?
