Android Studio Version here.

Fork of https://bitbucket.org/droidperception/simplewebcam. This displays the video video of your usb webcam connected to your android device.

1. The kernel is V4L2 enabled... I think this is true since kitkat. You can compile your own kernel with:

CONFIG_VIDEO_DEV=y

CONFIG_VIDEO_V4L2_COMMON=y

CONFIG_VIDEO_MEDIA=y

CONFIG_USB_VIDEO_CLASS=y

CONFIG_V4L_USB_DRIVERS=y

CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y

2. USB WebCam is UVC camera, and it supports 640x480 resolution with YUYV format. Tested with ELP-USBFHD01M-L21 (barebones webcam.. I think most should work).

Supported platform : Iconia Tab A500.

3. Your phone should be rooted. There's a command that runs su -c \"chmod 666 <video_loc>\", so it needs root permissions. I have superSU installed to manage root permissions.
   • Below android 4.4, you don't need root. You can use this patch: https://bitbucket.org/droidperception/simplewebcam/commits/415cd2b4a1a40a10f5e05a621e2ec494bb06d065

This application will also work on V4L2-enabled pandaboard and beagleboard.

4. ant, installed, ndk and sdk installed

$ cd <project-location>
$ <path-to-ndk>/ndk-build NDK_PROJECT_PATH=.
$ <path-to-sdk>/tools/android update project --path . --target android-19 # Optional, if you want a new build.xml and local.properties
$ ant debug
$ ~/Library/Android/sdk/platform-tools/adb install -r bin/Main-debug.apk

If this doesn't work, make sure you are reading from the correct video device. The code expects you're reading from /dev/video4. You may want to change this to /dev/video0. Check out the comments in CameraPreview.java for

	private int cameraId=0;
	private int cameraBase=4;
