Android调用科大讯飞语音转写 API以及解析踩坑之旅

需求

需要对本地音频文件，调用科大讯飞的api进行转文字，本来呢，以为很简单，结果坑不少。
语音转写 API 文档

坑1：解析

下载demo，代码也挺简单，放到idea中，替换一下key，直接运行，但是看到返回，傻眼了
在这里插入图片描述

这是后台代码，可以定一个方法作为回调，但是呢，又没有提供其他平台的sdk，所以android的怎么定义回调？总不能去后台绕一圈吧，所以只能走

Thread.sleep(7000);

这个就是很被动了。

坑2：android包冲突

本来觉得都是java代码，直接拿到android工程里就能用，在maven库里找到对应依赖的gradle版本，结果一运行，傻眼了，报错

java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; or its superclasses (declaration of ‘org.apache.http.conn.ssl.AllowAllHostnameVerifier’ appears in /system/framework/framework.jar!classes3.dex)

原因：经查看是 android_sdk中有一个 AllowAllHostnameVerifier 类没有INSTANCE字段

而httpclient-4.5.3.jar 中有 AllowAllHostnameVerifier 类有INSTANCE字段，而代码运行优先使用sdk中的AllowAllHostnameVerifier类了，所以报No static field INSTANCE；

就这个问题，在网上找了好几篇博客，按照他们的方法，都没有解决，发现一篇有用的博客，就是引入了cz.msebera.android:httpclient这个库代替HttpClient，然后把对应的org.apache.http的引用换成cz.msebera.android.httpclient，完美解决
cz.msebera.android:httpclient 最新版本
No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier；

坑3：用okhttp调用上传接口失败

既然用apache的网络引用有问题，那就换成android上的okhttp吧，但是这个upload接口比较奇怪，我用postman测试，
在这里插入图片描述
上传pcm文件，只能通过body的binary方式，其他的我试过，都不行。
试了好几种okhttp上传文件的方法，都行不通

坑4：Android进程切换

Java代码不涉及到控件和网络的切换，但是Android会涉及到，直接用java代码会报错：

android.os.NetworkOnMainThreadException

所以只能切换到子线程，但是得到结果以后，又要给控件赋值，又得切回到主线程
