How to handle the situation when Java method being called via JNI does not exist?

[Dmitriano]

If I call a Java method that does not exist with a code like this:

QAndroidJniEnvironment javaEnv;
QAndroidJniObject javaAd(QtAndroid::androidActivity());

javaAd.callMethod<void>("aWrongMethodName");

if (javaEnv->ExceptionCheck())
{
    javaEnv->ExceptionClear();

    qDebug() << " Java code has thrown an exception.";
}

javaAd.callMethod executes successfully, and javaEnv->ExceptionCheck() returns false, so it is not clear how to handle the situation when Java method being called does not exist.

Is there a way to make javaAd.callMethod throw an exception or set some error flag in such a case?

@Dmitriano there are a lot of errors in the log if the method does not exist, but there is no way to handle this situation:

@Dmitriano I guess QAndroidJniEnvironment::ExceptionCheck() purpose is to catch exception which occurred during function execution and not "function not exist" exception. So your use case is not covered.

Don't you have hand over Java code? Just create an empty function which throw an exception, this should be catchable with QAndroidJniEnvironment::ExceptionCheck().
