warning: 6.0.0-beta25 build errors, due to updated dependencies

[2x2xplz]

Not a bug, but a warning. Perhaps re-numbering to 6.1-beta is appropriate.

Upgrading from 6.0.0-beta24+1 to -beta25 updates dependencies, according to the changelog:

Updated androidx.webkit:webkit dependency to 1.8.0
Updated androidx.browser:browser dependency to 1.6.0

The androidx updates require Android 34, which in turn requires Android Gradle Plugin 8+, which is often going to require an upgrade (most existing projects are probably on AGP 7). Additionally, upgrading Gradle plugin from 7 to 8 sometimes introduces a namespace error, here's a SO issue describing the problem.

Typical error when trying to build with 6.0.0-beta25:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   > 2 issues were found when checking AAR metadata:

       1.  Dependency 'androidx.browser:browser:1.6.0' requires libraries and applications that
           depend on it to compile against version 34 or later of the
           Android APIs.

           :app is currently compiled against android-33.

           Also, the maximum recommended compile SDK version for Android Gradle
           plugin 7.4.2 is 33.

           Recommended action: Update this project's version of the Android Gradle
           plugin to one that supports 34, then update this project to use
           compileSdkVerion of at least 34.

           Note that updating a library or application's compileSdkVersion (which
           allows newer APIs to be used) can be done separately from updating
           targetSdkVersion (which opts the app in to new runtime behavior) and
           minSdkVersion (which determines which devices the app can be installed
           on).

👋 @2x2xplz

NOTE: This comment is auto-generated.

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

Same problem. Any update?

[MSmithDev]

Same here too

Same issue

Perhaps re-numbering to 6.1-beta is appropriate.

The problem with that is that the version 6.0.0 stable has not been already released, otherwise, I would have done it.

The only "fix" is to update your project to support also compileSdkVersion 34 and namespace value inside your android/app/build.gradle file.

You can also check the official Android guide to use Android Studio - Android Gradle plugin Upgrade Assistant

Also, you can check the current Android folder inside the flutter_inappwebview example, for example:

• android/build.gradle: https://github.com/pichillilorenzo/flutter_inappwebview/blob/master/flutter_inappwebview/example/android/build.gradle
• android/app/build.gradle: https://github.com/pichillilorenzo/flutter_inappwebview/blob/master/flutter_inappwebview/example/android/app/build.gradle
• android/gradle/wrapper/gradle-wrapper.properties: https://github.com/pichillilorenzo/flutter_inappwebview/blob/master/flutter_inappwebview/example/android/gradle/wrapper/gradle-wrapper.properties

Even I am facing the same issue

What went wrong:
A problem occurred configuring project ':flutter_inappwebview'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
  > Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

    If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

BUILD FAILED in 1s
Exception: Gradle task assembleDebug failed with exit code 1

[pichillilorenzo]

@PawanFyers it’s written in the error what you have to do. Check also my previous answer.

[pichillilorenzo]

By the way it should be ok also using classpath 'com.android.tools.build:gradle:7.3.0' and distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip.

The namespace attribute has been introduced starting from version 7.3.0: https://developer.android.com/build/releases/past-releases/agp-7-3-0-release-notes#package-deprecated.

So, in this case, the requirement is to have compileSdk/compileSdkVersion value to be at least 34.

[tmkook]

Has it been fixed? I also encountered it

[pichillilorenzo]

@tmkook it won’t fix. You need to upgrade your Android configuration as said in the previous comments.

This one still uses v33
