| # jni |
| |
| This is a support library to access JNI from Dart / Flutter code. This provides the common infrastructure to bindings generated by [jnigen](https://pub.dev/packages/jnigen), as well as some utility methods. |
| |
| This library contains: |
| |
| * functions to access the JNIEnv and JavaVM variables from JNI, and wrapper functions to those provided by JNI. JNIEnv is exposed via `GlobalJniEnv` type which provides a thin abstraction over JNIEnv, so that it can be used from multiple threads. |
| |
| * Functions to spawn a JVM on desktop platforms (`Jni.spawn`). |
| |
| * Some Android-specific helpers (get application context and current activity references). |
| |
| * `JObject` class, which provides base class for classes generated by jnigen. |
| |
| Apart from being the base library for code generated by `jnigen` this can also be used for one-off uses of the JNI and debugging. __To generate type-safe bindings from Java libraries, use `jnigen`.__ |
| |
| ## Documentation |
| The test/ directory contains files with comments explaining the basics of this module, and the example/ directory contains a flutter example which also touches some Android-specifics. |
| |
| Using this library assumes some familiarity with JNI - it's threading model and object references, among other things. |
