Question

After update to Android Studio Arctic Fox 2020.3.1 Patch 4,

Error: Could not resolve aapt2-7.0.4-7396180-windows.jar (com.android.tools.build:aapt2:7.0.4-7396180): No cached version

Execution failed for task ':app:processDebugResources'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > Failed to transform viewbinding-7.0.4.aar (androidx.databinding:viewbinding:7.0.4) to match attributes {artifactType=android-compiled-dependencies-resources, org.gradle.category=library, org.gradle.dependency.bundling=external, org.gradle.libraryelements=aar, org.gradle.status=release, org.gradle.usage=java-runtime}.
.
.




Possible solution:
 - Disable offline mode and rerun the build

if I disable offline mode and syn the project again. Then even its not building the project then errors comes again.

Error after disabling offline mode:

:app:writeDebugSigningConfigVersions

FAILURE: Build completed with 8 failures.

1: Task failed with an exception.

Disable Gradle 'offline mode' and sync project

even offline mode is deactivated.

What's wrong with it?

Even Firebase is not connecting to internet through firebase Assistant though Android Studio.

Answer 1

I found the culprit for this in my project. Earlier I was using in all projects repositories in build.gradle(Exam String)

maven {
            url 'https://dl.bintray.com/amulyakhare/maven'
        }

In earlier Android studio versions, it was working using this repositories.

After removing this from build.gradle(Exam String).

It started working fine.

It is used for liquide swipe view pager.

For reference I have added screenshot of repositories.
