At the end of today, my code is below, but it still doesn't work.
Any help is appreciated.
void MediaRegister::registerFile(const QString& file)
{
#ifdef ANDROID
QString real = file;
//real.replace("/0/", "/legacy/");
QAndroidJniObject string = QAndroidJniObject::fromString(real);
jobjectArray stringArray;
QAndroidJniEnvironment env;
stringArray = env->NewObjectArray(1, env->FindClass("java/lang/String"), NULL);
env->SetObjectArrayElement(stringArray, 0, string.object<jstring>());
QAndroidJniObject::callStaticMethod<void>("android/media/MediaScannerConnection",
"scanFile",
"(Landroid/content/Context;[Ljava/lang/String;[Ljava/lang/String;Landroid/media/MediaScannerConnection/OnScanCompletedListener)V",
QtAndroid::androidActivity().object<jobject>(),
stringArray, 0, 0);
env->DeleteLocalRef(string);
env->DeleteLocalRef(stringArray);
qDebug() << Q_FUNC_INFO << real;
#endif
}
