Webcam camera not work with android


I was install android build 99.
but webcam camera not work When i test a webcam app.
dose need something else?
In Debian it works fine.


The Android builds use a v3.10 based kernel and, whilst this kernel does have USB camera support enabled, the kernel is much older than the v4.4 kernel used for the Debian releases. As a result it is unlikely that Android can support the same range of cameras that Debian can.

Qualcomm has shared an application note on this subject. It describes the ADB shell commands you can use to determine whether or not the Android build supports you web camera (and also recommends a suitable test program to use to grab images):
