JNI Problem: Can't find my Java Class (worked pre 5.2)
-
Hey,
I got a Problem with my custom java class i added to my android app.
As I said it worked previously but after updating to Qt 5.2 I dont get the class when calling FindClass on my JNIEnv.calling:
env->FindClass("org/qtproject/qt5/android/QGooglePlayManager")
returns nothing.app crashes with:
D/AndroidRuntime(19137): Shutting down VM
W/dalvikvm(19137): threadid=1: thread exiting with uncaught exception (group=0x415cf700)
E/AndroidRuntime(19137): FATAL EXCEPTION: main

......I am not very experienced with setting up any build processes so i hope i just have to add the java file or class somewhere?!
Thanks,

Your need to use ANDROID_PACKAGE_SOURCE_DIR.
In your <project>.pro file, you might have:
ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android-sources
Then in your project directory, you would have a sub-directory called android-sources. The manifest file, if you need a special one, would go in this sub-directory and your java files would go under this in android-sources/src.
In fact, in the end we copied the complete 5.1.1 android\src sub-directory tree from the 5.1.1 into android-sources/src and deleted the java files that were not our own from the android-sources/src tree.
In the end it was simple, but finding out how to do it took ages!!
