Hello,

I having a huge problem when I launch or deploy my game to an Android device. Everything seems to go fine with the packaging and it get deployed and launched on the device. But when it runs, a long list appears in a message box saying:

Default Property warning and errors:  
Error: CDO Constructor (EditableText): Failed to  
find /Engine/EngineFonts/Roboto

Error: CDO Constructor (EditableTextBox): Failed to  
find /Engine/EngineFonts/Roboto

etc…

Error: CDO Constructor (DefaultPawn): Failed to  
find /Engine/EngineMeshes/Sphere

Error: CDO Constructor (TextRenderComponent):  
Failed to find /Engine/EngineFonts/RobotoDistanceField

etc…

Error CDO Constructor (Console): Failed to find  
/Engine/EngineResources/Black

Error CDO Constructor (Console):F ailed to find  
/Engine/EngineResources/WhiteSquareTexture

and so on. There are 33 items in total. Then I touch ‘ok’ and the app closes along with the message.  
Weirdly it only started happening recently. Am i supposed to manually put these in a folder somewhere? Is there a tick box im missing? Any help would be appreciated.

Thank you.

Can you try deleting your Saved directory in your project directory?

If that doesn’t work, try removing Intermediate (if you have a code based project), and rebuild.

Also, check out:

> Hello, To be specific: 1.What happend: My Android blueprint-only game was working perfectly in editor and on android device. After package .obb file had 700+mb. I wanted to resize .obb so I deleted: -. a lot of starter content I didn’t used...

Did you recently change the setting to put content inside the .apk file?

Thanks for the response, I tried deleting the saved directory, that didn’t work.

My project is completely Blueprints based.

But I do have the exact same error list as shown in that post, I’ve followed the steps he used to fix the problem, but it hasn’t made a difference. I changed the default font from Roboto to a custom one and the paper2d default textures. But It’s still saying the same thing. Is there a folder I need to clear after I change those? Any other ideas what it could be?

Thanks
