This commit adds an Android `webrtcsrc` based example with the following features: * A first view allows retrieving the producer list from the signaller (peer ids are uuids which are too long to tap, especially using an onscreen keyboard). * Selecting a producer opens a second view. The first available video stream is rendered on a native Surface. All the audio streams are rendered using `autoaudiosink`. Available Settings: * Signaller URI. * A toggle to prefer hardware decoding for OPUS, otherwise the app defaults to raising `opusdec`'s rank. Hardware decoding was moved aside since it was found to crash the app on all tested devices (2 smartphones, 1 tv). **Warning**: in order to ease testing, this demonstration application enables unencrypted network communication. See `AndroidManifest.xml`. The application uses the technologies currenlty proposed by Android Studio when creating a new project: * Kotlin as the default language, which is fully interoperable with Java and uses the same SDK. * gradle 8.6. * kotlin dialect for gradle. The structure is mostly the same as the previously preferred dialect, for which examples can be found online readily. * However, JNI code generation still uses Makefiles (instead of CMake) due to the need to call [`gstreamer-1.0.mk`] for `gstreamer_android` generation. Note: on-going work on that front: - https://gitlab.freedesktop.org/gstreamer/cerbero/-/merge_requests/1466 - https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6794 Current limitations: * x86 support is currently discarded as `gstreamer_android` libs generation fails (observed with `gstreamer-1.0-android-universal-1.24.3`). * A selector could be added to let the user chose the video streams and possibly decide whether to render all audio streams or just select one. Nice to have: * Support for the synchronization features of the `webrtc-precise-sync-recv` example (NTP clock, RFC 7273). * It could be nice to use Rust for the specific native code.
