android - 在 Android 4.2 上运行谷歌云语音 api
问题描述
我在 Android 4.2 设备上运行 io.grpc:grpc-okhttp 时遇到问题。
我已经使用 Credentials 实现了 SpeechClient，用于运行 Google 云语音到文本。在 Android 7.1 设备上我没有问题。问题发生在 Android 4.2
所以在我开始的时候我有
implementation 'io.grpc:grpc-okhttp:1.35.0'
implementation 'io.grpc:grpc-android:1.35.0'
implementation 'com.google.cloud:google-cloud-speech:1.24.0'
问题。
第一个问题是 SSL 的 TLS 安全性（在 Android 4.2 上太旧了）。为此，我添加了依赖项
implementation 'org.conscrypt:conscrypt-android:2.5.1'并在我的 DialogFragment （正在运行代码）中实现
Security.insertProviderAt(Conscrypt.newProvider(), 1)在我实施这个之后，我得到了
Duplicate class org.conscrypt.AbstractConscryptEngine found in modules jetified-conscrypt-android-2.5.1-runtime (org.conscrypt:conscrypt-android:2.5.1) and jetified-conscrypt-openjdk-uber-2.2.1 (org.conscrypt:conscrypt-openjdk-uber:2.2.1)问题（很多重复的类）所以为了解决这个问题，我添加了
configurations { all { exclude group: "org.conscrypt", module: "conscrypt-openjdk-uber" } }现在我收到此错误，因为 com.google.api.client 使用的是 Standard.UTF-8 而我的设备使用的是 Android 17。

问题：
- 如何解决此问题并使用“ApiStreamObserver”运行语音？我尝试将“io.grpc:grpc-”库恢复到 1.0 版或其他版本，但后来我遇到了其他问题......
解决方案
我已经解决了这个问题并在 Github 上提交了示例项目
https://github.com/DjToMeK27/CloudGoogleSpeechToText/tree/main
我在这个项目中做了什么
- 下载https://github.com/GoogleCloudPlatform/android-docs-samples/blob/master/README.md
- 更改了 android-docs-samples-master\speech 项目 SpeechRecognitionClient 中的类
- 更改 AudoEmitter.kt 中的 AudioRecord 以支持 API 16
- 导入 org.conscrypt:conscrypt-android:2.5.1 库
- 必须从 google-cloud-speech 中排除组 org.conscrypt（在 build.gradle 中）
- 添加了 init { Security.insertProviderAt(Conscrypt.newProvider(), 1) } 让 Android 4.1 运行正确的 TLS 以使 GRC 工作
- 我下载了 https://github.com/googleapis项目
- 将 google-http-client 中找到的所有 StandardCharset 更改为 Charset.forName())
- 并且还改变了一些测试来工作
- https://imgur.com/a/iU7yjCZ（文件更改）
- 我已经构建了这个项目并添加了 .jar 文件，我在此处包含了这些文件
- 现在它起作用了！
