问题描述

我正在尝试让 Android Things 项目在 Raspberry Pi 3 上构建和运行.找到这些文件此处.我通过以太网连接到我的 Raspberry Pi 3.我将以太网电缆从笔记本电脑直接插入到 rPi 并使用了 Internet 共享.然后我使用 adb connect 连接到设备并成功连接.

I am trying to get an Android Things project to build and run on a Raspberry Pi 3. The files are found here. I am connected to my Raspberry Pi 3 via Ethernet. I plugged the ethernet cable directly from my laptop to the rPi and used Internet Sharing. I then used adb connect to connect to the device and it successfully connects.

我正在跑步:

Android Studio 3.1.2
Build #AI-173.4720617, built on April 13, 2018
JRE: 1.8.0_152-release-1024-b01 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Mac OS X 10.12.6

对 Android Studio 进行了更改，因此我不得不更改一些代码.我下载了文件并将 PeripheralManagerService 更新为 PeripheralManager.

Changes were made to Android Studio so I had to change some code around. I downloaded the files and updated the PeripheralManagerService to PeripheralManager instead.

PeripheralManager pioService = PeripheralManager.getInstance();

当我单击运行"按钮时，出现以下错误(请记住，我已经在应用程序部分上方的 Android 清单文件中添加了以下权限):

When I click the Run button, I get the following error (please keep in mind that I already added the following permission to Android Manifest file above the application section):

<uses-permission android:name="com.google.android.things.permission.USE_PERIPHERAL_IO"/>

请帮我弄清楚我还缺少什么.谢谢！

Please help me with figure out what I am still missing. Thanks!
