Android SDK does not work

cbnewham

Hi,

Has anyone managed to get the Android SDK to work - or the demo? I'm running this on Android 10 on a OnePlus 5T using OTG to connect to a ASI120MC-S.

The APK zwo-camera-example.apk in the SDK download zip archive won't install ("install failed"). If I compile and run the demo I get a segmentation fault in the .so libraries caused by the JNI call:

ASIReturnType propertyReturn = ZwoCamera.getCameraProperty(i);

This also occurs if I set up a very simple app of my own. This call:

int num = ZwoCamera.getNumOfConnectedCameras();

lists one device as being connected and I can see it is the ZWO camera from the USB information returned by the device.

ZWO's ASICAP app downloaded from Google Play works perfectly, so it appears to be something wrong with the libraries provided in the SDK.

After investigation I have found it is due to the new security arrangements on Android 10. The Demo app provided in the SDK will fail if run on an Android device with Android 10 or higher. Maybe the drivers too - I don't know - I just copied the .so library files out of your ASICAP APK because they seem more up-to-date than the ones provided in the SDK.

ZWO, you need to update the SDK and the demo. Your ASICAP app works fine, so why don't you copy the relevant code into the Demo? Your code also doesn't support AndroidX.

cbnewham Thank you very much for your feedback, i forwarded this to our devs,

Same here. Any updates?

After getting permissions I still can't get it working. ZwoCamera.getCameraProperty(i); for 0 camera fails.

For UVC devices I can open file descriptor and use it later with libusb/libuvc but what should I do for ASI SDK?

Zzzz
