Try this code:

<application

        tools:replace="icon, label"> <-- Add this line in application tag

The problem is you are using different versions of support library. Try using same version for all the android support libraries.

In build.gradle file:

Change

com.android.support:recyclerview-v7:26.0.0-alpha1 to

com.android.support:recyclerview-v7:25.3.1

Try latest version libraries (25.3.1)

  buildToolsVersion "25.0.3"
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:support-v4:25.3.1'

Change in app.gradle

 classpath 'com.android.tools.build:gradle:2.3.3'
