3 Register XML file to integrate to the project

Then you need to insert build code into ProjectName.build.cs to compile this project.

1. Copy the following code.

if（Target.Platform == UnrealTargetPlatform.Android）
{
  PrivateDependencyModuleNames.AddRange(new string[] { "Launch" });

  String LocalPath = Utils.MakePathRelativeTo(ModuleDirectory, BuildConfiguration.RelativeEnginePath);

  AdditionalPropertiesForReceipt.Add(new ReceiptProperty("AndroidPlugin", (LocalPath + "/ filename.xml")));
}

2. Paste this segment into ProjectName.build.cs, (Highlighted in red.). Be aware that “filename.xml” should be

using UnrealBuildTool;
using System.IO;
public class MYJar : ModuleRules
{
  public MYJar(ReadOnlyTargetRules Target) : base(Target)
  {
    PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
    PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });
    PrivateDependencyModuleNames.AddRange(new string[] {  });

    // Uncomment if you are using Slate UI
    // PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });

    // Uncomment if you are using online features
    // PrivateDependencyModuleNames.Add("OnlineSubsystem");

    // To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
    if (Target.Platform == UnrealTargetPlatform.Android)
    {
        PrivateDependencyModuleNames.AddRange(new string[] { "Launch" });
        AdditionalPropertiesForReceipt.Add(new ReceiptProperty("AndroidPlugin", ModuleDirectory + "/CPPJAVAS.xml"));
    }
  }
}
