最近需要做一个类似于电话客户的功能，要求拨打电话能自动录音。所以写了一个dome，希望能够帮到大家。
主要思路就是监听手机通话状态在监听到接听时开始录音，结束停止录音。
AndroidManifest中配置
<!-- 权限 --> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" /> <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" /> <uses-permission android:name="android.permission.READ_CALL_LOG" /> <uses-permission android:name="android.permission.CALL_PHONE" /> <uses-permission android:name="android.permission.WRITE_CALL_LOG" /> <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
当然了还要在清单文件中注册service
