Hello KNI
=========
This is a Demo of Jni calling Kotlin Native originated from Google's jni demo.
### Contents
Kotlin Native can interop with C directly. In order to call Kotlin Native functions from Java, we should use `CName` to annotated the functions with a proper name:
```kotlin
@CName("Java_com_example_hellojni_HelloJni_stringFromJNI")
fun stringFromJNI(env: CPointer, thiz: jobject): jstring {
memScoped {
return env.pointed.pointed!!.NewStringUTF!!.invoke(env, "This is from Kotlin Native!!".cstr.ptr)!!
}
}
```
What's in the demo：
* Uses of Android Log
* Return a Java String
* Call Java methods from Kotlin Native
### How to Build
Simply Build and run your app. Dependencies are carefully managed by gradle.
