Detailed Description

\inmodule QtCore

Since

6.1

A convenience wrapper around the Java Native Interface (JNI).

The QJniObject class wraps a reference to a Java object, ensuring it isn't garbage-collected and providing access to most JNIEnv method calls (member, static) and fields (setter, getter). It eliminates much boiler-plate that would normally be needed, with direct JNI access, for every operation. Exceptions thrown by called Java methods are cleared by default, but can since Qt 6.11 also be handled by the caller.

Note

This API has been designed and tested for use with Android. It has not been tested for other platforms.
