简单记录一下开发中遇到的手机驱动外接摄像头，目前只能针对个别机型，像小米，魅族MX2，ZTE测试过是可行的，Lenovo，VIVO，华为由于关闭了外接设备，并不支持外接摄像头。摄像头要支持UVC软驱。另外要注意，摄像头预览分辨率要是手机/平板分辨率和摄像头支持的分辨率交集，Demo中将查看分辨率的代码解开（代码改为true）可以查看两者支持的分辨率。还是有很多问题的，距离商用还有一段距离，仅供参考，还请感兴趣的大牛联系完善。
在平板测试过程中发现性能比较好的品牌平板表现良好，不过遇到一个棘手的问题就是HOME与BACk键交叉使用会导致图像不再显示，手机显示蛮好，平板表现比较次。
项目创建
本项目在EC下创建取名为UVCDemo，包名：com.serenegiant.uvccamera，我们先把底层库引入：

核心代码
原理是使用UVCCamera来控制、管理与外接设备的连接，UVCCameraTextureView控件进行图像的预览，USBMonitor进行驱动的连接和断开
先在需要的地方添加控件：
-
<com.serenegiant.usb.widget.UVCCameraTextureView
-
android:id=
“@+id/camera_view”
-
android:layout_width=
“match_parent”
-
android:layout_height=
“match_parent”
-
android:layout_centerHorizontal=
“true”
-
android:layout_centerVertical=
“true” />
- 1
-
final View view = findViewById(R.id.camera_view);
-
mUVCCameraView = (CameraViewInterface)view;
-
mUVCCameraView.setAspectRatio(PREVIEW_WIDTH / (
float)PREVIEW_HEIGHT);
//TODO
-
mUSBMonitor =
new USBMonitor(
this, mOnDeviceConnectListener);
-
mHandler = CameraHandler.createHandler(
this, mUVCCameraView);

在使用“.so”库的时候记得添加库才能使用本地语言
