i’ve tried both options with obb and with single apk, doesn’t matter it can’t find the camera params.
First of all, i need this app to be downloadable from the google app store, i can’t tell users “you can install it only if you install android sdk and will use the bat file”, right?
Anyway the bat file doesn’t help.
Let me explain in details.
There are 3 ways how i can install an unreal app to a phone:
- Attach it through USB and press “” in UE Editor
- Package the app and install it through USB using the bat file
- Package the app and upload the apk (and if needed obb) file(s) to the google app store and download it from the store.
And see what happens:
It seems the app is looking for the files in 2 places: /storage/emulated/0/ and /sdcard/
When i have clear device and install the app using option 2 or 3, there are no artoolkit files neither in /storage/emulated/0/ nor in /sdcard/ and the camera doesn’t work.
If i use option 1, UE copies the files to /sdcard/ folder and the app works.
Even if i unuinstall the app the /sdcard/ fodler is still here with its content and further installations using any of the methods work, because the app is able to find the files in /sdcard/ folder.
I’ve checked the apk i install, it does contain assets folder with .zip (named as .obb.png), which contains the artoolkit folder and myappname-android.pak.
When I the app it displays GUI and for a second displays 3d model i use, only the camera fails. So it seems the assets are unpacked and used by the app with no problems except the artoolkit folder.
So it seems there is no problem with obb, but only with the artoolkit folder which is added as ‘additional’ folder to pack.
One more thing: I installed the unreal4ar demo from the store and it has content folder in ‘UE4Game/ArPluginV4_15/ArPluginV4_15’ which does contain the artoolkit folder. My app has all folders and similar structure except the content folder. Any ideas why it can be so?
