I have no problem building for Android until I start a C++ project or add a C++ class to an existing Blueprint project

Like the question says I can build and deploy to Android with no problem as long as it’s a pure Blueprint project. As soon as I start a C++ project or a C++ class to my Blueprint project I get crashes. The game says that it launches but my devices gets a black screen and crashes back to my home screen before I get any logs.

LogPlayLevel: adb: --------- beginning of main
LogPlayLevel: adb:
LogPlayLevel: adb: --------- beginning of system
LogPlayLevel: adb:
LogPlayLevel: adb: --------- beginning of crash
LogPlayLevel: adb:
LogPlayLevel: CommandUtils.Run: Run: Took 0.0820047s to run adb.exe, ExitCode=0
LogPlayLevel: CommandUtils.Run: Run: C:\\android-sdk-windows\platform-tools\adb.exe -s d0d0bee4 logcat -d
LogPlayLevel: CommandUtils.Run: Run: Took 0.122007s to run adb.exe, ExitCode=0

These are some of my the last logs. I’m using 4.15 and Andorid Codeworks 1r5. I’ve uninstalled both UE4 and Codeworks and re-installed them just to make sure it’s nothing there and I’m still getting the same problem.

FUNK_DADDY,

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.

Thank you!

Sorry, I just got back but I found the solution. My Java was out of date. Updated it and can build once again.
