Getting exception : java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14

问题

I updated Android Studio and the android design library recently since then I am getting an exception java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14.

Not sure what is the problem, I tried almost everything, its working in lollipop 5.1 device(nexus 4) but it does not work in Android 4.4 device and 4.02 device. It was working before the updation in all versions.

I tried all solutions mentioned in stackoverflow but nothing worked for me.

Also tried removing the line compile 'com.android.support:support-v4:22.2.0' in build.gradle but it did not work too.

Also tried cleaning and rebuilding and again it did not work.

I resolved this issue and if anyone is experiencing this issue try these options(3rd point fixed my problem):

Add multiDexEnabled true in defaultConfig of build.gradle.

defaultConfig { applicationId "com.something.ranjith.androidprojdel" minSdkVersion 15 targetSdkVersion 22 versionCode 1 versionName "1.0" multiDexEnabled true }
Remove android support library if your activity extends `AppcompatActivity'

compile 'com.android.support:support-v4:22.+' //remove this
If you have PlayServices in your app then remove the PlayServices and add the individual APIs. For eg:- if you are using PlayServices for ads then just add compile com.google.android.gms:play-services-ads:7.5.0 instead of compile com.google.android.gms:play-services:7.5.0

List of individual APIs of PlayServices:

Google+ com.google.android.gms:play-services-plus:7.5.0
Google Account Login com.google.android.gms:play-services-identity:7.5.0
Google Actions, Base Client Library com.google.android.gms:play-services-base:7.5.0
Google App Indexing com.google.android.gms:play-services-appindexing:7.5.0
Google App Invites com.google.android.gms:play-services-appinvite:7.5.0
Google Analytics com.google.android.gms:play-services-analytics:7.5.0
Google Cast com.google.android.gms:play-services-cast:7.5.0
Google Cloud Messaging com.google.android.gms:play-services-gcm:7.5.0
Google Drive com.google.android.gms:play-services-drive:7.5.0
Google Fit com.google.android.gms:play-services-fitness:7.5.0
Google Location, Activity Recognition, and Places
com.google.android.gms:play-services-location:7.5.0
