Android ARToolkit - Изображение показывает ошибку

Question

приложение работает хорошо, но после того, как я поставил «setContentView (R.layout.activity_main)» в моем классе, чтобы установить содержание и показать изображение говорит мне эту ошибку:

android.view.InflateException: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout 

Я наследовал от AndARActivity, чтобы сделать простое приложение для распознавания маркеров.

XML, с проблемой заключается в следующем:

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 
     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:fitsSystemWindows="true" 
     tools:context="webdata.com.mascotcollector.MainActivity"> 

     <android.support.design.widget.AppBarLayout 
      android:layout_height="wrap_content" 
      android:layout_width="match_parent" 
      android:theme="@style/AppTheme.AppBarOverlay"> 

      <android.support.v7.widget.Toolbar 
       android:id="@+id/toolbar" 
       android:layout_width="match_parent" 
       android:layout_height="?attr/actionBarSize" 
       android:background="?attr/colorPrimary" 
       app:popupTheme="@style/AppTheme.PopupOverlay" /> 

     </android.support.design.widget.AppBarLayout> 

     <include layout="@layout/content_main"/> 

     <android.support.design.widget.FloatingActionButton 
      android:id="@+id/fab" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_gravity="bottom|end" 
      android:layout_margin="@dimen/fab_margin" 
      app:srcCompat="@android:drawable/ic_dialog_email" /> 

</android.support.design.widget.CoordinatorLayout> 

Что я делаю неправильно?

Answer 1

Убедитесь, что вы правильно зависимость в файле gradle

compile 'com.android.support:design:25.0.1'
