extension-camera's Issues

Does not run on OSX

Trying to use extension-camera to read a QR code or OSX but it instantly crashes the running instance and only leaves this in the _crash.

Support bundling/building with unsupported platforms

Even though the project doesn't support a platform it would be nice if it could still make them bundle/build successfully.

Android support

There's experimental Android support in the Android branch, but that branch uses the Java APIs. We should look into using code from the NDK example: https://github.com/googlesamples/android-ndk/blob/master/camera/texture-view/src/main/cpp/camera_manager.cpp

Fails when compiling on iOS

Runtime exception when starting camera on Android OS

Samsung Galaxy S9+ , One UI-version 2.5, Android-version 10.

Cash on Android

Sometimes a released version of the app can crash with the camera. I haven't found it crashing on a debug build so far.
