The 'adjustments-for-arm64_v8a' branch of this fork of libdfuprog features the following changes

- adjustments of some library and include paths in libdfuprog_make_android so that aarch64 versions are used
- addition of some dependencies that may not come with official android ndks
- addition in /src/libusb-242/arm64-v8a of a 64 bit version of libusb.so fromhttps://github.com/louisgeek/LG_libusb_Android/tree/main 

---------------------------------------------------------------
libdfuprog is a fork of dfu-programmer with a bunch of hacky build scripts added so you can build it as a dynamic library.

It also adds support for Android versions 4 and later (including 7 and I think 8), via Vianney le Clément de Saint-Marcq's libusb fork.

To build it, run bootstrap.sh, then libdfuprog_make_<your_platform_here>.
You might need some prerequisites; check the original dfu-programmer page as well as libdfuprog_instructions in this repo.
You may also need to change the permissions of the build script to get it to run, e.g., via 'chmod u+x libdfuprog_make_<your_platform_here>'.
In addition, for arm64_v8a android builds (for which the 'adjustments-for-arm64_v8a' branch is appropriate), it will be necessary to change 
'path_to' in libdfuprog_make_android to a path leading to gcc.  Lastly, as commented on in that branch/file, in may be necessary to download
a fit-for-purpose version of gcc. 

After building, rename main.h to libdfuprog.h (AFTER building), and then add it to your includes.  Also don't forget to add libdfuprog-0.9.so to your libs.  :)

You can then make dfu commands by treating libdfuprog_virtual_cmd() as if it were a terminal running dfu-programmer!
Implementation is  a bit hacky on Android, as it closes the llibusb handle before returning...
Fortunately it's easy to make another one!

Check out the androidUsbDriver.cpp and unixUsbDriver.cpp files in my other repo (Labrador) for an example of how to use it:
