Describe the idea

Pls support gcj02 from china

Expected behaviour

There is a great layers amap from china, http://webst01.is.autonavi.com/appmaptile?x={$x}&y={$y}&z={$z}&lang=zh_cn&size=1&scale=1&style=8 which contains a wealth of data, and if it could be added to OsmAnd as an overlay, it would be fantastic.

Alternatives you've considered

Will there be legal issues in China to officially support this conversion?

I am not a professional legal expert, but I have seen that another project has already implemented this feature, which is a branch of osmand. https://github.com/swkim01/Osmand
