Qt and Android - How to launch camera by using Qandroidjniobject

HemantZ

I am new in Qt android app development. I want to open camera and take picture and get the path of image by using QtAndroid, and JNIObject.

For example,
Java code -

Intent capture_image_intent = new Intent();
capture_image_intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(capture_image_intent, 101);

I written this java code in Qt by using Qandroidjniobject. This is given below,
Qt code -

QAndroidJniObject ACTION_CAPTURE = QAndroidJniObject::fromString("android.provider.MediaStore.ACTION_IMAGE_CAPTURE");
            QAndroidJniObject intent("android/content/Intent");
            if (ACTION_CAPTURE.isValid() && intent.isValid())
            {
                intent.callObjectMethod("setAction", "(Ljava/lang/String;)Landroid/content/Intent;", ACTION_CAPTURE.object<jstring>());
                QtAndroid::startActivity(intent.object<jobject>(), 101, this);
                qDebug() << "OK";
            }
            else
            {
                qDebug() << "ERROR";
            }

Now, my question is by using above qt code my app cannot launch Camera. So, please help me for finding what is the problem?

I solved this above problem in Qt by using Qandroidjniobject.

For launching camera by using intent code is given below,

QAndroidJniObject ACTION_IMAGE_CAPTURE = 
   QAndroidJniObject::getStaticObjectField("android/provider/MediaStore", 
   "ACTION_IMAGE_CAPTURE", "Ljava/lang/String;");
QAndroidJniObject intent("android/content/Intent", "(Ljava/lang/String;)V", 
    ACTION_IMAGE_CAPTURE.object<jstring>());
QtAndroid::startActivity(intent.object<jobject>(), 101, this);

How did you get the taken picture from the camera?
