* Android: check if objectClass() is not null in registerNativeMethods()Assam Boudjelthia2021-11-152-12/+48
| | | | | | | | | | | | 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 Boudjelthia2021-06-021-2/+2
| | | | | | | | | | | 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.

* QJniEnvironment: extend APIIvan Solovev2021-05-032-0/+74
| | | | | | | | | | | | | | This patch adds some convenience methods to QJniEnvironment API: * an overload of registerNativeMethods() that accepts jclass instead of const char *className. * a findMethod() function is added to query a methodID of a static or nonstatic method by its name and signature.

* Replace conversion operator by operator* in QJniEnvironmentAssam Boudjelthia2021-04-141-3/+6
| | | | | | | | | | | Since conversion operators do implicit conversion that might bring some potential issues while using the API, let's stick to having an operator* instead.

* Fix registerNativeMethods for goodAssam Boudjelthia2021-02-113-0/+79
| | | | | | | | | | | | | | | | | The initial implementation and the commit c00ab6f8eaa3cdc9a29dd103c91b2eaf212cac9f was wrong: * env->findClass() in fact returns a global reference, and in any case we shouldn't be calling that, instead QJniObject would be enough. * The size param provided to env->RegisterNatives was wrong. * A test for registerNativeMethods() is added to ensure such break is not repeated again.

* Make QJniObject and QJniEnvironment public APIAssam Boudjelthia2021-01-272-0/+114
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.
