please try to add those codes in your AndroidMnifest.xml: < uses-permission android:name="android.permission.USB_PERMISSION" /> < uses-feature android:name="android.hardware.usb.host" android:required="true" />

It seems to be an issue with SDK versions. I have the same problem when I was trying with compileSdkVersion 28 and targetSdkVersion 28. I changed them to 25 and 22, respectively, just like in the sample app. It worked.

I have the same exception accidentally . don't know why.

遇到同样的异常，运行作者的demo app没有问题，但是把libusbcamera库移到自己的应用里之后，就报这个错误：java.lang.IllegalArgumentException: surface should be one of SurfaceHolder, Surface or SurfaceTexture: null

gradle里面 compileSdkVersion 28 targetSdkVersion 27 运行在rk3399板子上，android版本是9.0
