Failed to resolve: com.android.support:support-v4:23.0.0

Question

After update with the latest Android support library 23.1 i get this error

Failed to resolve: com.android.support:support-v4:23.0.0

Answer 1

Go to File -> Project Structure then select Dependencies tab and remove com.android.support:support-v4:23.0.0

It worked for me

Answer 2

Had to add "Android Support Repository" from SDK Manager.

Answer 3

I ran into the same problem today. Although the SDK Manager marked a few libraries as installed, investigating the location of the files showed me the correct folder structure, without any files in them.

For example, checking out the location of 23.1.0 appcompat-v7 on my Mac: .../sdk/extras/android/m2repository/com/android/support/appcompat-v7 turned out to be an empty folder.

I suspect the update I ran minutes before went wrong somehow.

What solved it for me:

1. in Android Studio, open Appearance and Behaviour -> System Settings -> SDK Manager
2. under tab "SDK Tools" un-check the libraries causing problems
3. click "apply" to uninstall them
4. re-check the same libraries
5. click "apply" to reinstall them
6. close SDK Manager and run Gradle sync / build

Answer 4

The support libraries are now available through Google's Maven repository.

Step 1: Open the build.gradle file of your project.

Step 2: Make sure that the repositories section includes a maven section with the "https://maven.google.com" url in it.

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
}

Answer 5

I got a similar problem, was trying to change versions and so on. Did not work for me. Only after I changed the version and restarted Studio it started to work. Probably gradle doesn't sync that normaly while you don't restart Studio.

Answer 6

In my case, opening SDK manager and installing Local Maven Repository for Support Libraries fixed my issue.
