Problem integrating CNSDK

Developer Tools Core SDK Android
1

Integrated Leia CNSDK into existing 3D model viewer android app.

Able to init the SDK and start the backlight OK.

But when attempting to postprocess after rendering into the SxS (Side-by-side) OpenGL viewports, get catastrophic crash with stacktrace:

Any insight appreciated if anyone else has solved this, thank you

Which sample were you following? Do you use native or Java API? Is this project open sourced? If not, can you share a build? (I can debug it if there are no active protection layer integrated that would prevent me from doing so)

Thank you George, apologies for the delay.

Using the CNSDKGettingStartedGLAndroidNative sample project

The target android app for CNSDK integration uses several C++ 3rd party libraries for loading models, image manipulation etc; it’s kotlin on the managed side but makes heavy use of JNI/NDK/C++ on the native side. Also integrates optional ARCore support, so camera permission declared in manifest and obviously required to be granted if user wishes to make use of that feature.

App is a closed source personal hobby project.

From the information you shared so far I cannot help you. You can’t share an apk either?
