Simple anroid game won't run on device

Hi guys,
I am just making my 1st android project in UE4,but when i deploy it on my device all I see is the splash screen “Your splash screen goes here”(I am guessing because i didn’t put any image or text for that) and the UE logo in the corner and the game doesn’t start. I am wondering if the problem is in my deployment or in my device since the device is old and cheap.
The device is: sm-g313H , single core 1.2GHz
more about the device: Samsung New Zealand | Mobile | TV | Home Appliances
Thank"s for any help!

some screenshots? is it working in PIE or mobile preview mode?

It is working fine in PIE and mobile preview the only difference is that in Mobile Preview the lighting looks different.
I am thinking that the problem is in my phone, because as i said in the 1st post it is old and cheap, but as you can see from the screenshots my so called game is not much of a thing.
Here are the screenshots:

and the Mobile Preview:

I"ve tried to run the Tappy Chicken from the App store and had the same problem, tried 2D Side Scroller template and had the same issue - splash screen with “your splash screen goes here” and the unreal engine logo in the corner.


In order to better assist you, I’m going to need for you to provide me the logs from your mobile device.

  • Attach your phone to the computer
  • Go here: C:\android-sdk-windows\tools
  • Open up Monitor.bat
  • Launch the program and save the logs

If you cannot get Monitor.bat to open, please go to:

  • C:\android-sdk-windows\tools\lib\monitor-x86
  • Open up Monitor.exe
  • Follow the instructions above

Make sure that you highlight all of the logs, because they do not save unless they’re highlighted.

Hi , thank"s for the help.
Ok, so i opened Monitor.exe and the log window immediately started exploding with content.
Since I’ve never done that before I don’t know what exactly you need and i filtered the “warn”, which are the warnings I guess?
When i tried to start my so called game on the device I saw that in the log.

Here is the .log file.(warnings[warn] only, if you want I will make new one, with everything.) [link text][2]

I do not see any UE4 information in the logs provided. Did you copy and paste all of the logs from Monitor.bat while the game was opening and shutting down?

What about now?

Your logs are unfortunately not giving us enough information to determine the issue. Could you please start with a very simple project (perhaps a Blank project with scalable 2d/3d instead of , make sure MobileHDR is off) and see if that works on your mobile device, or if we can obtain more logs.

Thank you!

Ok , started new Blank project with 2d/3d tried to launch it on the device, the log:

Do you have an excess amount of unused assets in your project? Please go through your project, remove any assets that you’re not using and then delete your Intermediate and Saved folders. After doing that, try to package again and launch onto your Android device. If it crashes again, please collect the logs. I’d like to see if the error changes.

Thank you!

OK , but in the last log that i gave you (that was the one with the New Blank project, scalable 2d/3d, no starter content) or you want to delete Intermediate and Saved folders from my project?
Anyways I will do both later tonight and will post.

I gave you that information based on your logs before the blank ones. I’ve been trying to narrow down what’s going on. Do you have another device you can test on?

These are the logs from my project, they should not be empty now.

I will try it on another device , because i think the problem is in the device since blank project and Tappy chicken from the play store doesnt work.

This is what I see when looking at your project. It looks like you’re having an issue with your BinderProxy.

  • Is the device as updated as it can go?
  • What type of device was tested on for these logs? That information isn’t listed in the logs provided.

It’s possible that some of the changes made in Java, or not updated on your device may be due to: [Documentation: Android Developers Blog][1]
