I am building an app in android studio, but the app refuse to sync.
I have added org.gradle.jvmargs=-Djava.net.preferIPv4Stack=true to the gradle.properties file.
I have navigated to:
File -> Sync Project with Gradle Files,
Build -> Rebuild Project, I have also restarted android studio. Yet all to no avail. It's showing me these three errors:
1) Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException: Could not resolve all artifacts for configuration ':classpath'.
2) Caused by: org.gradle.internal.resolve.ModuleVersionResolveException: Could not resolve com.android.tools.build:gradle:3.4.0.
3) Caused by: org.gradle.internal.resolve.ModuleVersionResolveException: No cached version of com.android.tools.build:gradle:3.4.0 available for offline mode.
How can solve this error? Thanks.
