Failed to Resolve: support-core-utils, support-compat, support-media-compat

May 15, 2019

I use Android Studio 3.3 to open an old project and bump into the following errors

ERROR: Failed to resolve: support-core-utils
ERROR: Failed to resolve: support-compat
ERROR: Failed to resolve: support-media-compat

The old project is using

compileSdkVersion 27
targetSdkVersion 27
buildToolsVersion unspecified
support libraries: 27.1.1

Android Studio 3.3 is using Android Gradle 3.2.1

NOTE: Android Studio Check Gradle Version

3.2.1 (October 2018)

With this update, you no longer need to specify a version for the SDK Build Tools. The Android Gradle plugin now uses version 28.0.3 by default.

It seems Android is using buildToolsVersion '28.0.3', and it would be advisable to upgrade SDK version and support library to 28 as well.

compileSdkVersion 28
targetSdkVersion 28

Support libraries

// https://mvnrepository.com/artifact/com.android.support/appcompat-v7?repo=google
def suppLibVersion = '28.0.0'

dependencies {
    implementation 'com.android.support:appcompat-v7:' + suppLibVersion
    implementation 'com.android.support:recyclerview-v7:' + suppLibVersion
    implementation 'com.android.support:cardview-v7:' + suppLibVersion
    implementation 'com.android.support:gridlayout-v7:' + suppLibVersion
    implementation 'com.android.support:support-v4:' + suppLibVersion
    implementation 'com.android.support:design:' + suppLibVersion
    implementation 'com.android.support:customtabs:' + suppLibVersion
}

The problems is resolved after changing SDK and support libraries version to 27.

NOTE: Probably need to migrate to androidx next.
