1 登录 讯飞 平台，申请账号，创建一个应用
具体步骤可以百度查找
2 进入”我的应用”，下载相应的SDK文件
选择语音听写（流式版）-> Android MSC
3 打开安卓，新建项目
创建一个EditText和一个Button
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<EditText
android:id="@+id/textShow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="what heard will be shown here"
android:text=""
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.344" />
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="SPEAK"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/textShow1"
app:layout_constraintVertical_bias="0.284" />
androidx.constraintlayout.widget.ConstraintLayout>
4 将在官网下载的Android SDK 压缩包中libs目录下所有子文件拷贝至Android工程的libs目录下
5 在安卓项目文件中添加.so文件
在build.gradle(Module:XXX)文件中，在android节点下加入下面的内容（代码的作用是使得项目找到libs下的libmsc.so文件）
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
比较新的Gradle版本，已经自动实现打包.so文件的功能（在拷贝libs目录下文件后，配置上面的代码，即可完成在项目中添加.so文件）
6 右击libs目录下的msc.jar文件，选择Add As Library
7 sdk下文件夹main/assets/，自带UI页面(iflytek文件夹)和相关其他服务资源文件(语法文件、音频示例、词表)，将该文件夹拷贝到项目main目录下
8 在工程 AndroidManifest.xml 文件中添加如下用户权限
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
9 编写java代码，实现语音听写功能
包名这里就不显示了
APPID
需要在讯飞平台”我的应用”界面中寻找
