NavInfo Map Navigation Application Development SDK [Navinfo Navigation SDK for Android] is a map navigation client application product development kit based on Android 2.3 version and above. Users can easily construct a variety of interactive applications based on map navigation. The NavInfo map navigation application product development SDK provides basic functions such as 3D map display and operation, location information search, navigation calculation, navigation process management, etc. It can be combined with MPS (GPS, base station, WIFI hybrid positioning) interface to achieve map positioning and other functions, to meet Different application needs of different users.

Feature introduction and experience

• Simulation Navigation

                      // simulated navigation
                      mNaviSession.setSimulationSpeed(1.0f);  // Set the speed of the simulated navigation
                      mNaviSession.enableSound(true);         // Open real-time voice announcement
                      mNaviSession.startSimulation();         // Start simulation
                      
                      // Simulated navigation end and start navigation must be paired
                      // Simulated navigation ends
                      if (mRouteBase != null) {
                          if (mNaviSession.isInSimulation()) {
                              mNaviSession.endSimulation();
                              mDemoMapView.setTouchZoom(false);
                              // End the simulated navigation back to the starting point
                              mDemoMapView.setCarPosition(mStartPoint);
                          }
                      }
                  

• HUD Navigation Mode

                      // Drive along XXX
                      distance = mNavigateData.getCurrentToNextTurnDistance();
                      // 200 meters
                      distanceText = GISUtils.formatDistance(distance, GISUtils.DistanceUnit.CN);
                      matcher = NUMBER_PATTERN.matcher(distanceText);
                      start = 0;
                      end = 0;
                      if (matcher.find()) {
                          start = matcher.start();
                          end = matcher.end();
                      }
                      numberDistance = distanceText.substring(start, end);
  
                      unite = distanceText.substring(end, distanceText.length());
                      distanceSize = R.dimen.F22;
                      driveNumSize = R.dimen.F24;
                      suffixSize = R.dimen.F14;
                      String yan = YAN + mRoadName;
                      SpannableStringBuilder yanStyle = new SpannableStringBuilder(yan);
                      
                      yanStyle.setSpan(new AbsoluteSizeSpan(LayoutUtils.getPxByDimens(suffixSize)), 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                      yanStyle.setSpan(new AbsoluteSizeSpan(LayoutUtils.getPxByDimens(distanceSize)), 1, yan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                      
                      String driveNum = typeKey + numberDistance + unite;
                      SpannableStringBuilder driveNumStyle = new SpannableStringBuilder(driveNum);
                      
                      driveNumStyle.setSpan(new AbsoluteSizeSpan(LayoutUtils.getPxByDimens(suffixSize)), 0, typeKey.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                      driveNumStyle.setSpan(new AbsoluteSizeSpan(LayoutUtils.getPxByDimens(driveNumSize)), typeKey.length(), typeKey.length() + numberDistance.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                      driveNumStyle.setSpan(new AbsoluteSizeSpan(LayoutUtils.getPxByDimens(suffixSize)), typeKey.length() + numberDistance.length(), driveNum.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                      
                      tvDistance.setText(yanStyle);
                      tvRoadName.setText(driveNumStyle);
                  

• Routing

                      // Navigation route planning
                      mRoutePlan = new RoutePlan();           // Instantiate the route plan
                      mRoutePlan.setStartPoint(mStartPoint);  // Set the starting point of the line plan
                      mRoutePlan.setEndPoint(mEndPoint);      // Set the line planning end point
                      mRoutePlan.setUseTmc(true);             // Set to use Tmc to calculate the way, that is, avoid the congestion calculation
                      
                      // According to the route planning and using the multi-result method to start the calculation, the return result may be 1-3 routes.
                      mNaviSession.getInstance().startRoute(mRoutePlan, NaviSession.RouteMethod.multipleResult);
                      // route result returns
