Changes

To build GVE, follow the instructions for setting up your mozconfig from the [https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Simple_Firefox_for_Android_build Firefox for Android build instructions], and then run <tt>  ./mach build && ./mach package && ./mach android install-geckoview_example</tt>  to build and install. You will need to enable WR by setting <tt>gfx.webrender.all</tt> to true either via <tt>about:config</tt> or in a [[Platform/Platform-specific_build_defines#Prefs_files |prefs file]] that is used by GeckoView. If you change any Rust/C++ code, you need to re-run <tt>./mach build binaries && ./mach package && ./mach android install-geckoview_example</tt> to get the updates on-device.
