更一般地说,如果设备有多个嵌入式摄像头,是否有办法初始化其中一个？

我没有在Android参考文档中找到它:

• https://developer.android.com/reference/android/hardware/Camera.html
• https://developer.android.com/reference/android/hardware/camera2/package-summary.html
• https://developer.android.com/reference/android/hardware/camera2/CameraManager.html

三星SHW-M100S有两个摄像头.如果没有参考使用两个相机,任何想法三星怎么做...？

我正在尝试直接使用Intent. 下面是我的代码——

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
            intent.putExtra("android.intent.extras.CAMERA_FACING", android.hardware.Camera.CameraInfo.CAMERA_FACING_FRONT);

            intent.putExtra("android.intent.extras.LENS_FACING_FRONT", 1);
            intent.putExtra("android.intent.extra.USE_FRONT_CAMERA", true);
        }

我的清单文件：--

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="some.package">
    <uses-permission android:name="android.permission.INTERNET" />
    <!--
         The ACCESS_COARSE/FINE_LOCATION permissions are not required to use
         Google Maps Android API v2, but you must specify either coarse or fine
         location permissions for the 'MyLocation' functionality.
