目录结构:
1、添加权限:
<uses-permission android:name="android.permission.RECORD_AUDIO"/> <uses-permission android:name="android.permission.WAKE_LOCK"/> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> <uses-permission android:name="android.permission.VIBRATE"/> <uses-permission android:name="android.permission.WRITE_SETTINGS"/> <uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL"/> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.CALL_PHONE"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />2、新建MediaRecorderUtils,复制以下源码:
