Provides access to the Java Native Interface.
The JavaClassWrapper singleton provides a way for the Godot application to send and receive data through the [url=https://developer.android.com/training/articles/perf-jni]Java Native Interface[/url] (JNI). [b]Note:[/b] This singleton is only available in Android builds. [codeblock] var LocalDateTime = JavaClassWrapper.wrap("java.time.LocalDateTime") var DateTimeFormatter = JavaClassWrapper.wrap("java.time.format.DateTimeFormatter")

var datetime = LocalDateTime.now() var formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm:ss")

print(datetime.format(formatter)) [/codeblock] [b]Warning:[/b] When calling Java methods, be sure to check [method JavaClassWrapper.get_exception] to check if the method threw an exception.
Returns the Java exception from the last call into a Java class. If there was no exception, it will return [code]null[/code]. [b]Note:[/b] This method only works on Android. On every other platform, this method will always return [code]null[/code].
Wraps a class defined in Java, and returns it as a [JavaClass] [Object] type that Godot can interact with. [b]Note:[/b] This method only works on Android. On every other platform, this method does nothing and returns an empty [JavaClass].
