依赖项

在android/app/build.gradle文件中添加以下依赖项：

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.github.HBiSoft:HBRecorder:2.0.3'
    implementation 'androidx.appcompat:appcompat:1.4.1'
}

在android/app/src/main/AndroidManifest.xml文件中添加以下权限：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example">

    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
</manifest>

在Info.plist文件中添加以下键值对：

<key>NSPhotoLibraryUsageDescription</key>
<string>保存视频到图库</string>
<key>NSMicrophoneUsageDescription</key>
<string>保存音频到视频</string>
