1. Be sure you are not using NDK 15, but NDK 14b
2. Support for cameras that do not have 640x480 in USBTest0 #175 apply this code change to get rid of resolution issue.
3. Provide your log or clues

Yes, i am using NDK 15
Pkg.Desc = Android NDK
Pkg.Revision = 15.1.4119039

Which NDK Version I need to use.

[sappho192]

Use NDK 14b. You can manually assign the location of NDK in "Project Structure" in Android Studio.

#175 's patch is getting best resolution that your camera supports.
If you know supported resolution of your camera, then just overwrite it to width and height variables.
