MIP App Inventor and turn by turn Navigation

[camila escobar]

Hi everyone,

First I would like to thank you for your great contributions and help. I am trying to build an application that can retrieve the navigation turn by turn instructions from the maps navigation system. The user should enter a destination address and the turn by turn navigation will be retrieved by the code (done in app inventor) and send through Bluetooth to an Arduino that will translate this into vibrations. For example, turn left in 50 m will send a number or a character that corresponds to one vibration, turn right two vibrations etc... I know that apparently the Google maps API doesn't let me use this information, and is best to use any other openSource like Mapquest. I already Have the part that sends data through Bluetooth, and how to use location services, however I am completely lost in the getting the directions part and using thins information, I just don't understand how they work or how they could be interfaced with app inventor if they can which am not sure, and I really want to be able to use App Inventor I have tried somethings ind android Studio and it is just impossible to understand for me.

 I hope there is a solution.

Thanks for tour time again and useful help you could be a lifesaver :)!!

Printed directions? Use the Google Location API using the Web control and parse the result to get detailed directions for long or complex routes.   A different solution, using a Map is here

Thanks for your answer but I don't wan just printed directions actually don't need them, I need real time turn-by-turn navigation using location sensor. And be able to use this info, for example If I am approaching by 10 m a turnpoint, use this as a cue that sends an specific signal by Bluetooth. (I already know how to call google maps or make the direections and I also have the Bluetooth transmission part, I am lost in the real time guiding and using that info). I will check the tutorial and see if it has what I am looking thanks.
