No static method getFont error

I got the above error and I will show you the solution.

[environment] Android OS version 7.0

Match devendency

It can be fixed by aligning the following in build.gradle.

compileSdkVersion
targetSdkVersion
support Library verseion

Before correction

`build.gradle`


compileSdkVersion 27
targetSdkVersion 27
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support:recyclerview-v7:26.1.0'
    implementation 'com.android.support:design:26.1.0'
    implementation 'com.android.support:cardview-v7:26.1.0'
    implementation 'com.android.support:leanback-v17:26.1.0'
}

Revised

`build.gradle`


compileSdkVersion 27
targetSdkVersion 27
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:recyclerview-v7:27.1.1
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1
    implementation 'com.android.support:leanback-v17:27.1.1'
}

I changed the place that was 26.1.0 to 27.1.1 according to compileSdkVersion. I had to match the version.
