Example of android plugin project with jnigen.
This plugin project contains custom code which uses the Android libraries. The bindings are generated using jnigen config and then used in flutter example, with help of package:jni APIs.
The command to regenerate JNI bindings is:
flutter run jnigen --config jnigen.yaml # run from notification_plugin project root
The example/ app must be built at least once in release mode (eg flutter build apk) before running jnigen. This is the equivalent of Gradle Sync in Android Studio, and enables jnigen to run a Gradle stub and determine release build's classpath, which contains the paths to relevant dependencies. Therefore a build must have been run after cleaning build directories, or updating Java dependencies. This is a known complexity of the Gradle build system, and if you know a solution, please contribute to issue discussion at #33.
