1. I get some crashes after splash screen occasionally (android) and sometimes it works. I saw something in this thread about permissions, but since it works sometimes, I don’t know if that’s really the issue. Could you run some checks to make it more stable and simply don’t work instead of crashing the whole app?
I did not experience this kind of crashes on my test devices. Can I ask your device type / android version ?
2. Like Jessekirbs, I’m also interested on the 2d barcode marker and am not able to reach that page. I want to unlock cosmetics based on real world products, so each issue would be a different code. Is that possible?
It’s a third party page, and went offline. I am looking for an alternative solution for this.
3. The 320x240 resolution. Is that recommended because of stability? Is there a way to use 320x240 for recognition but display the full resolution?
I don’t think it’s possible. 320x240 is recommended for older devices with less power and memory.
4. Can I bring it in a blueprint only project, or should I import the blueprint project into the C++ AR template from the sample?
It has to be a C++ project in case you want to package your project.
