Newcommer at Android development, and got this error. No clue what is wrong.

Error:Execution failed for task ':app:processDebugManifest'.

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from [com.android.support:appcompat-v7:26.0.0-alpha1] AndroidManifest.xml:27:9-38 is also present at [com.android.support:cardview-v7:25.3.1] AndroidManifest.xml:24:9-31 value=(25.3.1). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:25:5-27:41 to override.

You need to use the same version of support libraries either use 25.3.1 with all com.android.support dependencies or use 26.0.0-alpha1 for all.

 compile 'com.android.support:appcompat-v7:25.3.1'
 compile 'com.android.support:design:25.3.1'

or either 

 compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
 compile 'com.android.support:design:26.0.0-alpha1'

In your root level gradle file make sure you have added Google's Maven Repo like this:

allprojects {
    repositories {
        jcenter()
    maven { url "https://maven.google.com" }
    }
}

This will hopefully resolve it.
