UE4 Android build error, could not overwrite Project Properties file

Development Platform & Builds Mobile

I tried for many times to setup the development environment by using CodeWorksforAndroid-1R6u1-windows.exe, but always failed.
Luckily, I found someone upload the [NVPACK folder][1] which I think is suitable, since the version of UE I use is 4.18.3.
I copied the NVPACK folder and pointed the Editor to the install locations.

While I clicked “Configure Now”, it prompted that “Could not overwrite Project Properties file”.

@anonymous_user_4dd6e988 Chang ([Android Build Failed - Mobile - Unreal Engine Forums][4] ) and @ryuikuya ([https://answers.unrealengine.com/questions/333524/android-configure-now-error.html][5] ) both suggested to build Development + Android first.

Since the simple copy and paste of NVPACK, there is no Android option.

I need to add some paths manually.

  1. Add JAVA_HOME path (the validation succeeds by cmd: java –version);
  2. Run android.bat located in C:\NVPACK\android-sdk-windows\tools
  3. Add ANDROID_HOME path (the validation succeeds by cmd: adb version);
  4. Add ANT_HOME path (the validation succeeds by cmd: ant -version);
  5. Add NDK_ROOT path (I am not sure whether it succeed since the following image)

  1. Run Setup.bat;
  2. Run GenerateProjectFiles.bat;
  3. Open proj.sln, specify the configurations: Development + Android and build, but get stuck with the errors fully put in 1.log.

Could not move on.
Any help would be appreciate ; )

Finally, I fixed it by run Setup.bat -include=Android instead of Setup.bat.
Because the command Setup.bat, by default, only downloads the dependencies for the current platform. ([TUTORIAL] How to use Setup.bat and how to reduce download size]1)

Choosing Android I am getting an ugly error when building…

Severity Code Description Project File Line Suppression State
Error MSB3075 The command “…..\Build\BatchFiles\Build.bat UE4Editor Android Development -WaitMutex -FromMsBuild” exited with code 5. Please verify that you have sufficient rights to run this command. UE4 C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.MakeFile.Targets 44

Any ideas?

Had to create an empty file called “project.properties” in the given folder to make this work.

Thank you so much. Running setup.bat fixed the configuration problem.
