Thanks Agi! I will look through the Example.
It would be good if i could get the Example to compile so i can see how each feature looks. I could not find a GitHub version of the Example to download... so i tried copying each activity, manifest, layout, and gradle and recreating a AS project Example. But when I run it i get an error. Doing all that by hand I probably missed something. If there is no better way to get a copy of the Example... can you suggest what i may have missed by looking at the error? Caused by: groovy.lang.MissingPropertyException: Could not get unknown property 'topobjdir' for project ':app' of type org.gradle.api.Project. Thanks!

When rotating Android re-uses the process of your app and re-runs the initialization code, causing the runtime to be created a second time.

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].

My use case is ... There are presently 1.5 billion children out of school due to C19. I am making a quick Geckoview app that they can use to continue to learn from home on their family smart phone. Think Jelly Bean on up. I already 1.8 GB mother tongue html video curriculums that we have been using firefox for them to locally browse the curriculum. Here is where GeckoView comes in... it will be much easier for families to use an app integrated with the html viewing built in. Here are my hurdles to getting GV going in my app 1) On both 70.0.20190712095934 and 77.0.20200421094220 my S7 GV crashes when turning the phone between portrait and landscape. That seems like I must be doing something really wrong with setting up the GV session? (see my activity below) 2) I have some clients on 4.1. Is there a way of knowing which builds of GV support which min SDKs? Is there a way to tweak GV to get down to support 4.1? 3) What is the code I add to support tabs? Siblings in the same home then can use their own tab view after brother does his homework with no complaints. Thanks so much! Bob Achgill PS You can see from my code that I commented out lines in trying to set up the settings. There is not much in the way of examples to follow that I just didn't get AS giving me complaints on so i had to // them out. So please feel free to add to my humble attempts!
