* Android: check if objectClass() is not null in registerNativeMethods()Assam Boudjelthia2021-11-151-3/+4
| | | | | | | | | | | | In case the class doens't have a default constructor, checking for object.isValid() will give false because the object won't be created, however, the class could still be loaded and we could have a valid jclass.

* Add a const JNINativeMethod[] overload for registerNativeMethods()Assam Boudjelthia2021-06-021-5/+39
| | | | | | | | | | | The JNI interface expects a const JNINativeMethod[] and our wrapper takes a non-const. Also, this was causing refactoring of exisisting code with a const JNINativeMethod[] to fail because the call expects a non-const.

* Make QJniObject and QJniEnvironment public APIAssam Boudjelthia2021-01-271-0/+283
As part of Qt 6 restructring for the extras modules, this change exposes the Jni APIs which are very important for Android platform. This patch adds the APIs QJniObject, QJniEnvironment, QJniExceptionCleaner based from private QtCore and QtAndroidExtras. The Jni interface is cross-platform which justifies the name, but currently, this API is used mainly for Android, and the naming comes generic without Android keyword to avoid any future limitation on supporting other platforms. [ChangeLog][QtCore] Add new QJniObject, QJniEnvironment and QJniExceptionCleaner APIs.
