[GraphHopper] [Graphhopper]Next Instructions

Hi Fred

You could use this DistanceCalc to see if your current position is within the limit distance to the next instruction, ex:

Int number = 20;

DistanceCalc distCalc = Helper.DIST_EARTH;

                  

if (distCalc.calcDist(instruction.getPoints().getLat(0),

                                          instruction.getPoints().getLon(0),

                                          mylocation.getLatitude(), mylocation.getLongitude()) <= number) {

      //display instruction text or whatever you want…

String text = instruction.getTurnDescription(esTR);

Toast.makeText(context, text, Toast.LENGTH_LONG).show();

}

But How find this distance limit?

Check the docs of that method: "return the next Instruction or null if too far away".
You need to be within the distance limit for finding an instruction.
