Solved Do not see Java class. Why?

[bogong]

Hello all!

I am developing very simple application. Default from Qt Quick template within simple Java class:

package package.test.usingjava_v1;

public class MyJavaClass {

    public static int mTest(int inNumber) {

	return inNumber;
    }
}

in *.pro file

android {

    QT += androidextras

    ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android

    OTHER_FILES += \
	android/MyJavaClass.java
}

in *.cpp

QAndroidJniEnvironment* oJNIEnvironment = new QAndroidJniEnvironment();
	jclass oMyJavaClass = oJNIEnvironment->findClass("package/test/usingjava_v1/MyJavaClass");
	if(oMyJavaClass == NULL) {
		qDebug() << "MyJavaClass class not found";
	}

When trying to run see this error:

W System.err: java.lang.ClassNotFoundException: Didn't find class "package.test.usingjava_v1.MyJavaClass" on path: DexPathList[[zip file "/data/app/~~EJrl74Lo2NDhB_byCekDiw==/org.qtproject.example.UsingJava_v1-R50S85TnRsBibrRodxNU0A==/base.apk"],nativeLibraryDirectories=[/data/app/~~EJrl74Lo2NDhB_byCekDiw==/org.qtproject.example.UsingJava_v1-R50S85TnRsBibrRodxNU0A==/lib/x86, /data/app/~~EJrl74Lo2NDhB_byCekDiw==/org.qtproject.example.UsingJava_v1-R50S85TnRsBibrRodxNU0A==/base.apk!/lib/x86, /system/lib, /system_ext/lib]]

Why is that? What am I missing?

@bogong
where exactly did you put the java file inside the "$$PWD/android" directory?

[bogong]

@raven-worx Solution found there was troubles with class location. It wasn't in ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android/src. Forgotten about src. The example published here https://github.com/ArboreusSystems/arboreus_examples/tree/master/qt/UsingJava
