I ran into similar errors. when I tried to include the recyclerview dependencies from may build.gradle(Module: app) with a code like so.

//other build.gradle(Module: App) code above
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:1.0.0-alpha7'
    testCompile 'junit:junit:4.12'
    implementation 'com.android.support:recyclerview-v7:25.3.1'
}

So the simple way I fixed this is by changing the code to this, where I changed the implement to compile while retaining every other code and their version numbers.

//other build.gradle(Module: App) code above
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:1.0.0-alpha7'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:recyclerview-v7:25.3.1'
}

I hope this helps some one having similar issues. PS: The actual error was caused by implementation 'com.android.support:recyclerview-v7:25.3.1' and changing the code to compile 'com.android.support:recyclerview-v7:25.3.1' got it fixed.
