Android Studio cannot resolve symbol 'TabLayout'

Question

Cannot resolve symbol TabLayout ? How to clear this error? Please help me. I already imported import android.support.design.widget.TabLayout;

Answer 1

Under Gradle Scripts, Open build.gradle (Module: app)

Inside of dependencies add

compile 'com.android.support:design:25.3.1'

There may be a newer version of the library available, the android studio lint check may detect that.

The full dependencies area may look like this for reference. The above line is the only one I manually added.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:25.3.1'
}

An above answer suggested adding

compile 'com.android.support:design:+'

Which is kind of dangerous because it always uses the latest library, you may have trouble isolating bugs with automatic library updates happening in the background.
