Game not starting on phone

Hello everyone!

We wanna test our game on mobile, but we got a weird issue. When we are trying to launch, the build proccess goes all fine, but the phone game hangs on the splashscreen. On the PC we get a constant ticking message saying “Waiting for server…” We also have a new CMD window, which does not take any input. Anyone has ever seen something like this before? Any idea how to fix it?

Thank you all in advance!


  • Could you please upload screenshots of your project launcher profile?
  • Upload the full logs from the output logs as a .txt file.
  • Upload your Android SDK from the project settings too.
  • Are you able to launch on and package without using the project launcher?


Dear ,

I could get it “a bit” working by disabling Firewall, and adding an empty C++ class to the project, and manually building Android Binaries from Visual Studio. However in this case the game hangs right after starting, saying that it cannot find the .uproject file (it’s in the default Documents/UnrealProjects/ folder.

Could you please provide me with the logs and I’ll need to see the error too. If the error isn’t appearing in the logs, provide me a screenshot if possible.

Thank you!

That’s the problem. The logs are completely clear. Build success, deploy success. Run success. The game screen has one single error, which says that it cannot find the /././././MyGame.uproject file. I tap OK and it closes :confused:

Obtain your logs from the device, please follow these steps:

  • 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.

Thank you!
