It is somehow a follow-up of [JDK-8245575](https://bugs.openjdk.java.net/browse/JDK-8245575), where the same was added for iOS. While no test can be provided, the current changes have been tested, building and deploying on Android. ------------- Commit messages: - Dispatch menu event on Android from native Changes: https://git.openjdk.org/jfx/pull/843/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=843&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8290841 Stats: 43 lines in 4 files changed: 39 ins; 0 del; 4 mod Patch: https://git.openjdk.org/jfx/pull/843.diff Fetch: git fetch https://git.openjdk.org/jfx pull/843/head:pull/843 PR: https://git.openjdk.org/jfx/pull/843
