Failed Exporting

[jain-aayush1123]

On exporting for android, the build fails. Have followed #234 (comment) to export for Unity 2019. The error says IL2CPP failed. I am using the correct NDK and all.
The Complete error is -

`Exception: C:\Program Files\Unity\Hub\Editor\2019\2019.4.14f1\Editor\Data\il2cpp/build/deploy/net471/il2cpp.exe did not run properly!

Opened Build.cs file and edited it : changed doBuild function of the android target
looking for this line
var options = BuildOptions.AllowDebugging.AcceptExternalModificationsToPlayer;
and change it to something else like that
var options = BuildOptions.AllowDebugging;
and it worked.

yeah that works when there is build failed to append error. here there was a problem with il2cpp not able to compile OpenURL library of unity. I got rid of those functions and it worked.
Thanks for your help ☺

Which functions did you remove? @jain-aayush1123 What exactly did you do?

So in my error it showed that the build was failing because of two functions which launched and closed URLs. Apparently, IL2CPP was not able to build those two. So I removed them and it was able to build.
Apart from that you need to follow #234 (comment)

Hope that helps

[cmd-dev]

Thanks for the reply! @jain-aayush1123

But, I followed #234 -

public static void DoBuildAndroid(String buildPath, bool isPlugin)
{
    if (Directory.Exists(apkPath))
        Directory.Delete(apkPath, true);

    if (Directory.Exists(androidExportPath))
        Directory.Delete(androidExportPath, true);

    // EditorUserBuildSettings.androidBuildSystem = AndroidBuildSystem.Gradle;

    // var options = BuildOptions.AcceptExternalModificationsToPlayer;
    var options = BuildOptions.AllowDebugging;
    EditorUserBuildSettings.exportAsGoogleAndroidProject = true;

    var report = BuildPipeline.BuildPlayer(
        GetEnabledScenes(),
        apkPath,
        BuildTarget.Android,
        options
    );

    if (report.summary.result != BuildResult.Succeeded)
        throw new Exception("Build failed");

    Copy(buildPath, androidExportPath);

...

I still get the same error for some reason.

[jain-aayush1123]

@cmd-dev you might have to go through your error log to figure out what's failing the build. It seems to pop up the roughly same error for multiple reasons. The error logs give the functions or classes which are failing the build. Try to remove those or find a workaround.

Okay thank you.

The problem was due to no disk space being left. I made some space and restarted my laptop and it fixed the issue.
