Member Function Documentation

[deprecated in 6.2] bool QJniEnvironment::registerNativeMethods(const char *className, JNINativeMethod[] methods, int size)

This function is deprecated since 6.2. We strongly advise against using it in new code.

This is an overloaded function.

Use the overload with a const JNINativeMethod[] instead.

Registers the Java methods in the array methods of size size, each of which can call native C++ functions from class className. These methods must be registered before any attempt to call them.

Returns true if the registration is successful, otherwise false.

Each element in the methods array consists of:

  • The Java method name
  • Method signature
  • The C++ functions that will be executed
JNINativeMethod methods[] = {{"callNativeOne", "(I)V", reinterpret_cast<void *>(fromJavaOne)},
                             {"callNativeTwo", "(I)V", reinterpret_cast<void *>(fromJavaTwo)}};
QJniEnvironment env;
env.registerNativeMethods("org/qtproject/android/TestJavaClass", methods, 2);
