Android Things robot car controlled by a companion app using local Nearby APIs

Android Things Robocar

Introduction

This project contains all the code required to build a robot car that runs on Android Things, as well as a companion "controller" Android app.

This sample uses the following Google platforms and APIs:

• Android Things - The car's onboard operating system.
• Nearby APIs - Local communication API used for pairing the robocar to a companion app which controls the car.

Note: The Android Things Console will be turned down for non-commercial use on January 5, 2022. For more details, see the FAQ page.

Pre-requisites

To build the car, you will need the following hardware:

• An Android-Things powered device with a connected camera. This demo ran on a Raspberry Pi 3, but is in no way limited to that device.

• A robot car chassis. We had great luck with the Runt rover robotics kit.

• A power source. The developer board and DC motors each need their own power input, so you can either get two small power packs or something like the Anker Powercore 13000, which has two USB-out ports.

• The Adafruit stepper & DC Motor hat, for controlling the motors.

(Optional) To assist in distinguishing between multiple robocars during the pairing process, the robocar also supports alphanumeric displays or RGB LED's for displaying a pairing code. Note that this is meant to assist the user, and is not intended or sufficient as a security measure. If you'd like to add these to your setup, you'll need:

• A quad alphanumeric display

• An RGB Led

• A half-size breadboard

Enable auto-launch behavior

This Android Things app is currently configured to launch only when deployed from your development machine. To enable the main activity to launch automatically on boot, add the following intent-filter to the app's manifest file:

<activity ...>

    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.HOME"/>
        <category android:name="android.intent.category.DEFAULT"/>
    </intent-filter>

</activity>

I am using NearBy 2.0 API version 'com.google.android.gms:play-services-nearby:12.0.1' with android things'com.google.android.things:androidthings:1.0'to create a smart home app, but previously upto 8th may it was working fine with the build downloaded from android things console , but from yesterday it is throwing com.google.android.gms.common.api.ApiException:8007 STATUS_BLUETOOTH_ERROR. when i am starting advertisement or discovery whichever maybe. But if I use the previous build(image with apk) of 8th may it is working fine . I tried with that old apk also like new os image with old apk , found not working. In logcat i found it is unable to start listening for incoming connections. I searched SO and google a lot but no solution worked. Even followed this https://stackoverflow.com/questions/46036191/error-codes-in-nearby-connections-2-0/46328410 but no luck. I am using Raspberry PI 3 model B. Help!!
