In my project Android Studio is giving a rendering problem in xml, giving the following error:

Rendering Problems The following classes could not be found: - android.support.v7.internal.app.WindowDecorActionBar (Fix Build Path, Create Class) Tip: Try to build the project.

And my Dependency Gradle looks like this:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile('com.mikepenz:materialdrawer:4.4.8@aar') {
    transitive = true
}
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'
compile 'com.android.support:cardview-v7:23.1.1'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.daimajia.easing:library:1.0.1@aar'
compile 'com.daimajia.androidanimations:library:1.1.3@aar'
compile 'com.melnykov:floatingactionbutton:1.3.0'
compile 'com.github.shell-software:fab:1.0.5'
compile 'com.github.clans:fab:1.4.0'
compile 'me.drakeet.materialdialog:library:1.2.2'
}

My example xml that has a problem:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="br.com.ciaware.people.activities.MainActivity" >

<android.support.v7.widget.Toolbar
    android:id="@+id/tb_main"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentLeft="true"
    android:background="?attr/colorPrimary"
    android:elevation="0dp"
    android:minHeight="?attr/actionBarSize"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

<br.com.ciaware.people.extras.SlidingTabLayout
    android:id="@+id/stl_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />


<android.support.v4.view.ViewPager
    android:id="@+id/vp_tabs"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

 </RelativeLayout>

And in Messages, these errors appear

Error: (11, 68) cvc-elt.1: Can not find the declaration of element 'RelativeLayout'.

Error: (1, 56) s4s-elt-schema-ns: The namespace of element 'x' must be from the schema namespace, ' link '.

Error: (1, 56) schema_reference.4: Failed to read schema document 'null', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not.

And in the Gradle console it looks like this:

I solved the problem by changing the dependency to a more current version 'com.daimajia.slider: library: 1.1.5@aar', I would like to sync Gradle, then go to the Android Studio Files menu and Invalidate Caches and Restart

The problem is that you are using the 23.1.1 version of appcompat-v7 together with ActionBar .

There are three solutions:

Revert to version 23.0.1
Subset ActionBar with ToolBar and make your theme descend from Theme.AppCompat.Light.NoActionBar or Theme.AppCompat.Dark.NoActionBar

Use the ToolBar in "Standalone " by not adding it to Activity with setSupportActionBar(toolbar); . In this case you can use any AppCompat theme , however you will have to fill it manually with content / actions, it is necessary to "inflate" a menu for it:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.blah);

    Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);

    // Set an OnMenuItemClickListener to handle menu item clicks
    toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            // Handle the menu item
            return true;
        }
    });

    // Inflate a menu to be displayed in the toolbar
    toolbar.inflateMenu(R.menu.your_toolbar_menu);
}

I had this same problem when I upgraded to 23.1.1 . It was here that I found the reason and solution.

Note:
If the issue is caused by any of the third-party libraries, you'll need to see if there is an update that is compatible with the 23.1.1 version of appcompat-v7 , if there is no you need to downgrade to a supported version.
