In order to the Android Support Library, we need to add the support library to dependencies in build.gradle. For example, add the following lines.

dependencies {
compile ‘com.android.support:design:25.1.0'
compile ‘com.android.support:appcompat-v7:25.1.0’
}

When do you update the support library version?

In my case, when IDE recommends to update SDK at the right top corner or when I open the SDK manager which provides the SDK tools, platforms, and others, I download and update the selected packages.

After downloaded, targetSdkVersion of defaultConfig shows the warning message with yellow underline “Not targeting the latest versions of android compatibility modes apply. consider testing this version.” for being compatible with the latest Android changes, so let’s set targetSdkVersion to 25 (Android 7.1) and run gradle build.

Finally, we will see the notice which means the support library version must be replaced to the latest version you have in your SDK and the targetSdkVersion must be the same.

How to check the latest version of android support library in your SDK?

Andorid Support Repository is local maven repository which contains all the support libraries as AAR archives from Android.

As the result, you will find the latest version of support library in your local SDK. Update 25.0.1 version for com.android.support:appcompat-v7, sync project with Gradle files and run project.
