There are poorly documented features in Qt for Android - we can use Intent features by JNI (Java Native Interface). There are some examples with startActivity equivalent, but I did not find any with result receiving.
Here's Java code with ilustration what I want to do:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
getActivity().startActivityForResult(intent, 1);
I used documentation to write equivalent in Qt:
QAndroidJniObject ACTION_GET_CONTENT = QAndroidJniObject::getStaticObjectField<jstring>("android/content/Intent", "ACTION_GET_CONTENT");
QAndroidJniObject intent("android/content/Intent");
if (ACTION_GET_CONTENT.isValid() && intent.isValid()) {
intent.callObjectMethod("setAction", "(Ljava/lang/string;)V", ACTION_GET_CONTENT.object<jstring>());
intent.callObjectMethod("setType", "(Ljava/lang/string;)V", QAndroidJniObject::fromString("file/*").object<jstring>());
QtAndroid::startActivity(intent, EXISTING_FILE_NAME_REQUEST, receiver);
return true;
} else {
return false;
}
receiver is a pointer to object of class, which extends abstract class QAndroidActivityResultReceiver. Here's it's implementation of virtual function handleActivityResult:
void MyReceiver::handleActivityResult(int receiverRequestCode, int resultCode, const QAndroidJniObject &data)
{
jint RESULT_OK = QAndroidJniObject::getStaticField<jint>("android/app/Activity", "RESULT_OK");
if (receiverRequestCode == EXISTING_FILE_NAME_REQUEST && resultCode == RESULT_OK) {
QString path = data.callObjectMethod("getData", "()Landroid/net/Uri;").callObjectMethod("getPath", "()Ljava/lang/String;").toString();
_dialog->emitExistingFileNameReady(path);
} else {
_dialog->emitExistingFileNameReady(QString());
}
}
Something is wrong with my code, because when I run it, following error messages appears (and program is being aborted):
