When I use Android phone to visualize the "/scan" data, it occured this problem

or

@tony1213 which Android application are you using to visualize "/scan" data?

[tony1213]

This application is developing by myself ,using the Module”android_10“and the Module "android_15".In my Android Application, bulid.gradle(Module app) with this:

dependencies{ ... compile project(':android_15') ... }

develop platform: Hardware: Turtlebot2 , rplidar A2 Android Phone:Lenovo PHAB2 PRO IDE: Android Studio 2.2.2

OK, we're likely going to be doing some work in this area in the next few weeks. It is not immediate, but we will keep it in mind and update this issue if we find a solution or need more information.

Maybe I solve the problem by manipulate the LaserScanLayer.This is Modified part：

... // Calculate the coordinates of the laser range values. for (int i = 0; i < ranges.length; i += stride) { float range = ranges[i]; // Ignore ranges that are outside the defined range. We are not overly // concerned about the accuracy of the visualization and this is makes it // look a lot nicer. if (minimumRange < range && range < maximumRange) { // x, y, z vertexBackBuffer.put((float) (range Math.cos(angle))); vertexBackBuffer.put((float) (range Math.sin(angle))); vertexBackBuffer.put(0); } else { vertexBackBuffer.put(0); vertexBackBuffer.put(0); vertexBackBuffer.put(0); } angle += angleIncrement * stride; } ...
