- Make sure you run “GenerateProjectFiles.bat” to create the project files and UE4.sln
- Open UE4.sln in Visual Studio 2013
- Select “Development” from the solution configurations
- Select “Android” or “Tegra-Android” from the solution platforms
- Open up Engine and right click on UE4 and select Rebuild
That should do it. If you want to confirm, check in Engine/Binaries/Android and see the timestamp on
UE4Game-armv7-es2.so; it should be new. Now you can use this for launching or packaging.
