I added an extra constructor: bytearray(std::vector<unsigned char>::iterator ptr, std::vector<unsigned char>::iterator size) : data_(ptr, size) {}

And... I don't have nativehelper. I don't know where/how you got it for the NDK.

Same here...

ld: error: unable to find library -lnativehelper

@kdewald can you point us in the right direction?

[Andrey1994]

nativehelper is available since 31, builds ok for me with -DANDROID_NATIVE_API_LEVEL=android-31

[kdewald]

Hey all, thanks for all the enthusiasm around Android support!

Please be patient as things are still in an early alpha stage, but don't hesitate to highlight any issues.

[felixdollack]

I am actually using it natively (C-lang) through Flutter, so it is still different from using Android/Kotlin ^^;

[Andrey1994]

I am also trying to use it slightly differently.
Just started and dont fully understand how it should work.
I have a C++ codebase with existing Java binding, and I already have JNIenv pointer in Cpp code. And it currently uses SimpleBLE for desktop. So, I dont need any methods from SimpleBLE to be available from Java, its 100% on Cpp level.

So afaiu I need a way to pass this pointer into SimpleBLE. @kdewald I dont see how to do this wo patching, do you have any ideas?
