Error building app when build variants are added - Android Studio

[murasu]

I have successfully 'ported' my app from Cocos2d-x 3.x to Axmol. It was truly a delight to work with a refreshed framework :)

I am facing a problem in Android Studio. After compiling and running my app, I added build variants to get different versions of the app (targeting different people in different regions).

I am able to compile the apk. However, the axslc assets are not getting copied into the package. In other words, the first part of the Gradle script android.applicationVariants.all { variant -> .. } works. The files in Content are copied over. The second part that copies files from ${projectDir}/../build/runtime/axslc is not getting executed at all.

Before adding the variants, both parts run without any issues.

I'm not a Gradle expert. Appreciate any pointers on where I should look for solutions. Thanks.

How did you set up the variants? Are you able to provide a sample project with a similar variants/flavors set-up that reproduces the issue?

[murasu]

I will try and setup a sample project. That may be easier :)

[rh101]

Never mind! I found the issue. Give me a few minutes to figure out what you can do about it.

[murasu]

Awesome! Will look forward. Thank you!

At the end of the app/build.gradle file, look for this section:

project.afterEvaluate {
    if (tasks.findByName("externalNativeBuildDebug")) {
        copyDebugAxslcToAssets.dependsOn externalNativeBuildDebug
        compileDebugJavaWithJavac.dependsOn copyDebugAxslcToAssets
    }
    if (tasks.findByName("externalNativeBuildRelease")) {
        copyReleaseAxslcToAssets.dependsOn externalNativeBuildRelease
        compileReleaseJavaWithJavac.dependsOn copyReleaseAxslcToAssets
    }
}

You may need to update that section with your required variants. For example, if your variant is named "custom":

project.afterEvaluate {
    if (tasks.findByName("externalNativeBuildDebug")) {
        copyDebugAxslcToAssets.dependsOn externalNativeBuildDebug
        compileDebugJavaWithJavac.dependsOn copyDebugAxslcToAssets
    }
    if (tasks.findByName("externalNativeBuildRelease")) {
        copyReleaseAxslcToAssets.dependsOn externalNativeBuildRelease
        compileReleaseJavaWithJavac.dependsOn copyReleaseAxslcToAssets
    }

    // New section for the "custom" variant (note the naming)
    if (tasks.findByName("externalNativeBuildCustom")) {
        copyCustomAxslcToAssets.dependsOn externalNativeBuildCustom
        compileCustomJavaWithJavac.dependsOn copyCustomAxslcToAssets
    }
}

I'm not sure if this can somehow be automated based on the variants, but for now, see if that works for you.

[murasu]

This works! I had to append 'Debug' and 'Release' accordingly. For example:

    if (tasks.findByName("externalNativeBuildCustomDebug")) {
        copyCustomDebugAxslcToAssets.dependsOn externalNativeBuildCustomDebug
        compileCustomDebugJavaWithJavac.dependsOn copyCustomDebugAxslcToAssets
    }

    if (tasks.findByName("externalNativeBuildCustomRelease")) {
        copyCustomReleaseAxslcToAssets.dependsOn externalNativeBuildCustomRelease
        compileCustomReleaseJavaWithJavac.dependsOn copyCustomReleaseAxslcToAssets
    }

Does this make sense?

[rh101]

Does this make sense?

Sure, assuming your variant names are "CustomDebug" and "CustomRelease"; is that correct?

Regardless though, at least now you have a solution to get it all working.

[murasu]

Absolutely! Thank you!
