The process of navigating a route on Android is a bit complicated so I’ll give detailed instructions. First, we need to install and set up the GPS mapping software. This part only needs to be done once.
Install OsmAnd. It’s a great app with all the features we need.
Launch OsmAnd, and go to Settings->Navigation->Voice Guidance and select your language.
In Settings->Data Management download the maps for the area you are interested in (e.g. your country or state).
Next, we need to get the route into the phone. This is best done when the phone is connected to a PC rather than directly on the phone.
