Hi Bob, that's pretty cool! GeckoView should support Android 4.1 (API level 16) for all versions, however we don't test on that version, so you might encounter bugs.
The crash on rotation is probably due to the fact that you're trying to create a GeckoRuntime in the same process, you can deal with this using a static variable for the runtime, see [1]. GeckoViewExample (code linked above) supports tabs, you can get an idea how to implement that from reading the code. In essence you would create a `GeckoSession` for each tab and then call `geckoView.setSession(session)`, see also [2].
