Using Qt Bluetooth for Android App without QtActivity

[Folami Nguyen]

Dear experts!

My team is developing common bluetooth library for both iOS/Android.

iOS is OK however Android has problem.

I see that in Qt Bluetooth for Android, they are using JNI in order that C++ call Java.

Now my application has another JNI (Java call C++)

I use QAndroidJniObject::callStaticMethod with classname and failed 

But if I use QAndroidJniObject::callStaticMethod with jclass parameter, it is successful.

I think that this problem is come from class loader isn't set rightly.

Are there any experts can shed me light?

Best regards
