Building go library and Android app - Go module errors

[zenonasz]

Hi, first of all, I very much appreciate your efforts. A lot of knowledge and architectural practices and principles have been put into this project.

I know that the project has been inactive for some time (except for some of your libraries on different repos which are still active).
I ended on your repo after researching off-the-grid communications for a similar use case as your initiative to start the project (although I have build meshtastic and reticulum, I am looking for solutions pretty much simal to yours)

I tried to build the project so I started with the go module library "wpgate-aar" which I still haven't successfully build.

I tried your suggestion and use the dockerize gomobile image from https://github.com/mysteriumnetwork/xgomobile .
after many trials and errors, I used the below command executed from root folder of the project:

docker run --rm \
    -v "$PWD"/build:/build \
    -v "$PWD":/go/src \
    -w /go/src \
    -e OUT=Mysterium \
    -e FLAG_V=true \
    -e FLAG_X=true \
    -e FLAG_RACE=true \
    -e FLAG_BUILDMODE=default \
    -e TARGETS=android/. \
    -e GO111MODULE=off \
    mysteriumnetwork/xgomobile:1.13.8 ./android/wpgate-aar

something to notice above is that I mount the root project directory to the default dockerized GOPATH. This is because if I used another directory e.g. ' -v "$PWD":/app ' I was getting build errors and I notice that the image was still trying to fetch './android/wpgate-aar' from the default dockerized GOPATH e.g. '/go/src./android/wpgate-aar'.

Currently the command that I posted is the closest on achieving something but I still get errors.
Here is the output of the docker run command above:

any suggestions?
do I follow the right direction?

Again thanks for your effort and I hope you see this post :)

P.S Happy new year
