I'am using DirectionalViewPager from library android-directionalviewpager-1.2.1fixed.jar with android.support.v4 (r11).

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical" >
   <android.support.v4.view.DirectionalViewPager
     android:id="@+id/pager"
     android:layout_width="fill_parent"
     android:layout_height="0dp"
     android:layout_weight="1"  />
</LinearLayout>

When I run application I have errors:

E/AndroidRuntime(15335): FATAL EXCEPTION: main E/AndroidRuntime(15335): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.w/com.example.w.MainActivity}: android.view.InflateException: Binary XML file line #6: Error inflating class android.support.v4.view.DirectionalViewPager E/AndroidRuntime(15335):at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1654) E/AndroidRuntime(15335): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1670) E/AndroidRuntime(15335): at android.app.ActivityThread.access$1500(ActivityThread.java:117) E/AndroidRuntime(15335): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) E/AndroidRuntime(15335): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime(15335): at android.os.Looper.loop(Looper.java:130) E/AndroidRuntime(15335): at android.app.ActivityThread.main(ActivityThread.java:3695) E/AndroidRuntime(15335): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime(15335): at java.lang.reflect.Method.invoke(Method.java:507) E/AndroidRuntime(15335): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:842) E/AndroidRuntime(15335): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:600) E/AndroidRuntime(15335): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime(15335): Caused by: android.view.InflateException: Binary XML file line #6: Error inflating class android.support.v4.view.DirectionalViewPager E/AndroidRuntime(15335): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:581) E/AndroidRuntime(15335): at android.view.LayoutInflater.rInflate(LayoutInflater.java:623) E/AndroidRuntime(15335): at android.view.LayoutInflater.inflate(LayoutInflater.java:408) E/AndroidRuntime(15335): at android.view.LayoutInflater.inflate(LayoutInflater.java:320) E/AndroidRuntime(15335): at android.view.LayoutInflater.inflate(LayoutInflater.java:276) E/AndroidRuntime(15335): at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:207) E/AndroidRuntime(15335): at android.app.Activity.setContentView(Activity.java:1657) E/AndroidRuntime(15335): at com.example.w.MainActivity.onCreate(MainActivity.java:12) E/AndroidRuntime(15335): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) E/AndroidRuntime(15335): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1618) E/AndroidRuntime(15335): ... 11 more E/AndroidRuntime(15335): Caused by: java.lang.ClassNotFoundException: android.support.v4.view.DirectionalViewPager in loader dalvik.system.PathClassLoader[/data/app/com.example.w-2.apk] E/AndroidRuntime(15335): at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:240) E/AndroidRuntime(15335): at java.lang.ClassLoader.loadClass(ClassLoader.java:551) E/AndroidRuntime(15335): at java.lang.ClassLoader.loadClass(ClassLoader.java:511) E/AndroidRuntime(15335): at android.view.LayoutInflater.createView(LayoutInflater.java:471) E/AndroidRuntime(15335): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:570) E/AndroidRuntime(15335): ... 20 more

I encountered a similar problem, the reason is that the android-support-v4.jar library used by DirectionalViewPager library being older version and making it not compatible with currently using version for development. Maybe you can use the below library for replacement. https://github.com/castorflex/VerticalViewPager

In addition, you can also refer to the below link might be helpful.

It's because this class is not a part of support library.

Try this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
android:orientation="vertical" >
<com.directionalviewpager.DirectionalViewPager
 android:id="@+id/pager"
 android:layout_width="fill_parent"
 android:layout_height="0dp"
 android:layout_weight="1"  />
</LinearLayout>

You have an instruction how to use it here: https://github.com/JakeWharton/Android-DirectionalViewPager
