Android app. error (FEngineLoop::Init()+188)

i’ve built a simple app for android with .obb and i couldn’t test it. so the first user run i got an error
i think that maybe .obb file wasn’t downloaded, but looks like it’s something about

apk was compiled for “All” androids about 160mb apk=20m + obb=130

Hi OeAi,

Is your build failing, or is your app crashing on the device? If it’s the former, can you attach output logs of the failed build to this thread? If it’s the latter, can you add the whole logcat?


build was ok and this is the bug-report from user ( crashing on device )
i’ve just upgraded to 4.7.5 and made rebuild, not sure when there’s gonna be another feedback

Starting from my phone i got “Failed to open descriptor file game.uproject” - what can be wrong?
i’ve repacked obb with zip 9

Can you attach logcat logs for this failure to this thread as a txt file? Thanks!

didn’t analyse it yet, it’s from my phone (should be simply unsupported), can’t get the tablet to try it out, error about “no .project file” after i click ok i see in logcat red fatal error and long list of errors goes then.
to be clear this game is a slightly tweaked version of MemoryGame i can share sources or provide links for apk/exe, exe - works.

Hi OeAi,

When you packaged, did you put the obb inside the apk?

Also, looks like a shipping log, which isn’t gonna really help much for diagnosing your problem. Can you package your project for development and give us those logcat logs?

The ‘failed to open descriptor file game.uproject’ error does likely mean that either the obb is missing, or the uproject was not packaged, and it does not seem to be the latter if you were not getting failed builds.


obb is not inside apk (can’t be more than 50mb)
i’ve renamed .obb to zip, then exrtacted folder, then packed that folder into zip 9 and renamed to obb - google tells it’s ok and i’m downloading both, without zip 9 it’s about 250mb. is there any check about hash or checksum or anything for separate obb?
dev. edition - a bit later

Hi OeAi,

Regarding the zip file, some info from the Android dev: it is supposed to be an uncompressed ZIP file written with our own zip packer. What you must do is cook with -pak -compressed so the PAK file in the ZIP is compressed instead of ZIP compressing the PAK.

Hope this helps!

ok i’ll try

can you explain how to do that properly?
i don’t know how to invoke buildCookRun from UE console
when i’m trying to put build string from console to cmd i got errors
slightly modified string can build it in intermediate but it’s not pushing apk into declared directory
there’s no additional fields in editor to put -compress (-pak is already marked)
string from console looks like that

BuildCookRun -rocket -nocompile -nocodeproject -installed -nop4 -project=C:/Users/1/Documents/Unreal Projects/Alphabet/Alphabet.uproject -cook -allmaps -stage -archive -archivedirectory=C:/Users/1/Unreal/5 -package -clientconfig=Shipping -ue4exe=UE4Editor-Cmd.exe -clean -pak -distribution -nodebuginfo -targetplatform=Android -utf8output -NoCompile

and woking cmd string looks like this

UE4Editor-Cmd.exe -project=C:/Users/1/Documents/Unreal Projects/Alphabet/Alphabet.uproject -run=cook -allmaps -stage -pak -distribution -package -clientconfig=Shipping -nodebuginfo -targetplatform=Android -archive -archivedirectory=C:/Users/1/Unreal/5 

i thought to add -compress into some file.ini, but i didn’t find where

next goes after Cooking DefaultNormal.uasset

not sure if it is useful

Hi OeAi,

Here is the documentation for how to cook from the command line, which is how you would add that command, and here is another AnswerHub thread where in a dev explains a little bit more in depth how you want to word the commands for best effect.

Hope this helps, lemme know how it works out.

Hi OeAi,

Checking in to see if you were able to use the command line cooking instructions to any effect.


Hi OeAi,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.

Thank you.

i remember something about new version, maybe some"compress" checkbox will be added later…


There are further instructions above from April 23, April 20 being the last time we heard from you. Did you get a chance to try them out?

i can’t test it on tablet, i’ve made apk without compress and put it in app store and also i’ve tried to run it on my phone - with no success, i think my phone not supporting opengl at all, but in some later maybe i’ll add a logcat with debug, just atm am busy with setting up computers for better performance.

Ok, I’m gonna close this out until you can get back to it. Thanks.
