Warning: When calling Java methods, be sure to check get_exception to check if the method threw an exception.
Methods
get_exception
Returns the Java exception from the last call into a Java class. If there was no exception, it will return null
.
Note: This method only works on Android. On every other platform, this method will always return null
.
JavaObject get_exception
wrap(String)
Wraps a class defined in Java, and returns it as a JavaClass Object type that Godot can interact with.
When wrapping inner (nested) classes, use $
instead of .
to separate them. For example, JavaClassWrapper.wrap("android.view.WindowManager$LayoutParams")
wraps the WindowManager.LayoutParams class.
Note: This method only works on Android. On every other platform, this method does nothing and returns an empty JavaClass.
