Hey Bob. I agree, getting an example to compile is a good first step. Unfortunately we don't provide a version on github, but maybe we should.
We have an example project on github that uses Android Components which provides many reusable components on top of GeckoView [1] If you still want to build GeckoViewExample what you need to do is add a root build.gradle file like this one that specifies topobjdir: [2] change this line to refer to a released version of GeckoView: [3] e.g. "org.mozilla.geckoview:geckoview-nightly:78.0.20200505094621" and remove this line [4]. feel free to chat with us at https://chat.mozilla.org/#/room/#geckoview:mozilla.org Cheers, [1]: https://github.com/mozilla-mobile/reference-browser [2]: https://github.com/mozilla-mobile/gradle-apilint/blob/master/build.gradle [3]: https://searchfox.org/mozilla-central/rev/dc4560dcaafd79375b9411fdbbaaebb0a59a93ac/mobile/android/geckoview_example/build.gradle#56 [4]: https://searchfox.org/mozilla-central/rev/dc4560dcaafd79375b9411fdbbaaebb0a59a93ac/mobile/android/geckoview_example/build.gradle#5 On Wed, May 6, 2020 at 12:30 PM Bob Achgill <bobachg...@hotmail.com> wrote: > 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.
