Q: The following classes could not be instantiated: android.support.design.widget.CoordinatorLayout Anybody know what this is about?
Here are my dependencies:
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:design:22.2.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:cardview-v7:22.0.0'
    compile 'com.android.support:gridlayout-v7:22.0.0'
    compile 'com.android.support:palette-v7:22.0.0'
    compile 'com.android.support:recyclerview-v7:22.0.0'
}

I imported everything from the Android Support Library and synced the Gradles. Anybody know why I am getting rendering problems in the layout? 
Here is the error log:

A: Am also faced same problem as per your scenario after import the support libraries and synced the Gradles need to rebuild your project.
After i have done this procedure its working for me, i hope this will helpful.

A: 
The following classes could not be instantiated: android.support.design.widget.CoordinatorLayout

This is simply because android.support.design.widget.CoordinatorLayout is added in version 24.1.0. So, the support library dependency is incorrect. The dependencies should be updated at least to version 24.1.0 or using the latest support libraries (28.0.0). Something like this:
dependencies {

    compile 'com.android.support:design:28.0.0'
    compile 'com.android.support:appcompat-v7:28.0.0'
    compile 'com.android.support:cardview-v7:28.0.0'
    compile 'com.android.support:gridlayout-v7:28.0.0'
    compile 'com.android.support:palette-v7:28.0.0'
    compile 'com.android.support:recyclerview-v7:28.0.0'
}
