android录像和拍照功能
先在 manifest 里添加权限
<uses-permission android:name="android.permission.CAMERA" />
<!-- 调用摄像头权限 -->
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<!-- 录制视频/音频权限 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- sd卡读写权限 -->
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<!-- 挂载sd卡 -->
