Apk Variant Output

[lordmyke]

I'm getting this build error:
Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.

How can i fix this?

In Android Studio open "artifacts.gradle".

Change this:

To this:

Then resync Gradle. It will give you sync errors:

Click "Update Build Tools version and sync project" for each of the errors. It will take a few times to clear the list.

This problem still exists in 1.0.7

This issue to due to using a newer version of gradle with Android Studio 3 and above. Changing the artifacts.gradle file as indicated in #14 is correct. However, you also may have to update your gradle version of the project. If you don't want to do this, use an older version of Android Studio; earlier than Version 3.

I did this and now I'm getting this error: Gradle DSL method not found: 'deleteAllActions()'

Not sure how to fix this, I'm not getting the option to update build tools version

Hi iknowzo,

Please see the following forum thread where I answered a similar question (see the first comment under the original question):

Hi @levonlevonian
I'm facing some issues here related to this thread.

I'm working on Android Studio 3.4.2 with the Fire App Builder to develop our Fire Tv application.
Out of the box the Fire App Builder can't build an APK even before I touch any code.
The issue was the "Unsupported version of Gradle". So, I upgraded the Gradle version to 3.4.2. After hit click on Sync project button, another error poped up that states that the "Minimum supported Gradle version is 5.1.1" So I went to graddle-wrapper.properties file and upgraded the Gradle version to 5.1.1-all.zip. Then I hit the Sync project button and the console says that "Cannot set the valur of read-only property 'outputFile' for APKVAriantOutput…" So, after some googling I stumble upon this thread and followed the @robdaven instructions. After hitting the sync button again the error says that the "Gradle DSL method not found 'deleteAllActions()'", So I tracked the issue down to the Amazon's forum that you point. I've added the google() repo but the same error stands.

I've tried to Clean & Rebuild the project, but I only get a lot of warnings complaining about a bunch of deprecated methods. I guess that happens when you try to work with outdated forks of Android on an Updated Android Studio Environment

I've even tried to match the versions you used in your responses but It still complains about mismatched Gradle versions.

Obviously I'm not going to downgrade Android Studio just for this development. Is there a workaround for this or I would need to use an old version of Android to be able to develop an app for Fire Tv?

Hi @HelaGone

For Gradle, are you using a wrapper or a local distribution? You can check that in Preferences, under "Build, Execution, Deployment", and then "Gradle".

If you are using the wrapper, then normally Android Studio offers to update the wrapper for you if you click on the error telling you that it is not a supported version. Otherwise, go to /gradle/wrapper/gradle-wrapper.properties file, which contains a line that will look something like this: distributionUrl=https://services.gradle.org/distributions/gradle-X.Y.Z-all.zip -- here change the version at the end to a supported version.

If you are using the local distribution, then again you will need to update your local Gradle to a supported version, or ideally switch to using the wrapper, which is a recommended way.

It's not clear what you mean by "or I would need to use an old version of Android to be able to develop an app for Fire Tv?" What device and OS version are you testing your app on? Normally, you would connect to your Fire TV and build, run and test your app directly on it. Thanks!

Hi @levonlevonian
I'm testing the application on a Fire Stick Gen 2. The application runs perfectly when I side load it to the Fire Stick.

For Gradle I'm using the one that comes with the Fire App Builder, which is the wrapper.
Indeed, for testing purposes, I've downloaded the Fire App Builder, build the project as is and tried to generate the APK but I got the same issue. It can't compile the APK due to the errors in Gradle's compatibility.

After try your suggestions I stumble on this error:
Gradle DSL method not found: 'deleteAllActions()'

Which is the same isse described by @iknowzo. I've followed the link you provide, and did the changes accordingly, but the error persists.

This is the output:
org.gradle.api.ProjectConfigurationException: A problem occurred configuring project ':ContentBrowser'.

Caused by: com.android.build.gradle.internal.crash.ExternalApiUsageException: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method deleteAllActions() for arguments [] on task ':ContentBrowser:extractDebugAnnotations' of type com.android.build.gradle.tasks.ExtractAnnotations.

Here's my setup:

        // in the individual module build.gradle files
    }

            maven { url rootProject.mavenUrl }
        }
    }

        if (output.zipAlign) {
            newApkName = "${appName}-${output.baseName}-${variant.versionName}.apk"
