Error : Failed To Find: Com.android.support:support-v4:20.0.+

I have imported a project in Android Studio that was built in it. I require v4 and v7 library in the project. This is how my build.gradle looks like build.gradle apply plugin: 'and

Solution 1:

The Android support repository was missing,So go to Android SDK, install the Android Support Repository and Android Support Library. Also you can use the following

compile'com.android.support:support-v4:20.0.0'compile'com.android.support:appcompat-v7:20.0.0'

instead of

compile'com.android.support:appcompat-v7:20.0.+'compile'com.android.support:support-v4:20.0.+'

Solution 2:

Note: If you're developing with Android Studio, select and install the Android Support Repository item instead.

see here.

Solution 3:

From Android Studio go to: Tools >> Android >> SDK Manager

Select and install "Extras|Android Support Repository"

Solution 4:

add maven to your gradle file (project)

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

and use this gradle wrapper:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

and downgrade to gradle plugin to be 2.3.1

classpath 'com.android.tools.build:gradle:2.3.1'
