I should also mention that MX Mariner is not OpenCPN
for Android as it doesn't share any code. I do mention Dave in the credits since MXM was inspired by OpenCPN.
However, I do hopefully soon plan on starting an open source library that will render vector charts
for the osmdroid and/or mapsforge libraries. This library will most likely share some java versions of some Opencpn code. And hopefully with the authors permission I will be able to re-license this code LGPL or BSD so it can be included in MXM.
