Updated SDK version, getting ClassNotFoundException: android.support.v4.view.ViewPager
android
Solution
Go to `Project`->`Properties`->`Java Build Path` than select `Order and export` tab. Set android-support-v4.jar library checked and up it into top of the list. And then clean and rebuild project.
Problem
When i was working on my Android project i found Logcat to be annoying (not keeping the scroll bar at a given point) and read that updating SDK versions adds a pause button to combat this issue. I updated to SDK version 17 and now i am having some strange problems that i didn't have before. I deleted and added the android support library but no luck. Ive been reading around the interwebs but i still cant figure it out. Log is below. ``` 03-22 15:54:18.558: E/AndroidRuntime(11597): FATAL EXCEPTION: main 03-22 15:54:18.558: E/AndroidRuntime(11597): java.lang.RuntimeException: Unable to start activity ComponentInfo{kris.android/kris.android.ActivityPortfolio}: android.view.InflateException: Binary XML file line #184: Error inflating class android.support.v4.view.ViewPager 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1821) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1842) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.ActivityThread.access$1500(ActivityThread.java:132) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1038) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.os.Handler.dispatchMessage(Handler.java:99) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.os.Looper.loop(Looper.java:150) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.ActivityThread.main(ActivityThread.java:4263) 03-22 15:54:18.558: E/AndroidRuntime(11597): at java.lang.reflect.Method.invokeNative(Native Method) 03-22 15:54:18.558: E/AndroidRuntime(11597): at java.lang.reflect.Method.invoke(Method.java:507) 03-22 15:54:18.558: E/AndroidRuntime(11597): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 03-22 15:54:18.558: E/AndroidRuntime(11597): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 03-22 15:54:18.558: E/AndroidRuntime(11597): at dalvik.system.NativeStart.main(Native Method) 03-22 15:54:18.558: E/AndroidRuntime(11597): Caused by: android.view.InflateException: Binary XML file line #184: Error inflating class android.support.v4.view.ViewPager 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:581) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.rInflate(LayoutInflater.java:623) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.rInflate(LayoutInflater.java:626) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.inflate(LayoutInflater.java:408) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.inflate(LayoutInflater.java:320) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.inflate(LayoutInflater.java:276) 03-22 15:54:18.558: E/AndroidRuntime(11597): at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:231) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.Activity.setContentView(Activity.java:1742) 03-22 15:54:18.558: E/AndroidRuntime(11597): at kris.android.ActivityPortfolio.onCreate(ActivityPortfolio.java:44) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1072) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1785) 03-22 15:54:18.558: E/AndroidRuntime(11597): ... 11 more 03-22 15:54:18.558: E/AndroidRuntime(11597): Caused by: java.lang.ClassNotFoundException: android.support.v4.view.ViewPager in loader dalvik.system.PathClassLoader[/data/app/kris.android-2.apk] 03-22 15:54:18.558: E/AndroidRuntime(11597): at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:240) 03-22 15:54:18.558: E/AndroidRuntime(11597): at java.lang.ClassLoader.loadClass(ClassLoader.java:551) 03-22 15:54:18.558: E/AndroidRuntime(11597): at java.lang.ClassLoader.loadClass(ClassLoader.java:511) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.createView(LayoutInflater.java:471) 03-22 15:54:18.558: E/AndroidRuntime(11597): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:570) 03-22 15:54:18.558: E/AndroidRuntime(11597): ... 21 more ```
