java.util.zip.ZipException: duplicate entry: android/support/v4/accessibilityservice/AccessibilityServiceInfoCompatJellyBeanMr2.class -

i integrating project app in android studio shows below error, googling issue no use.

error:execution failed task ':app:packagealldebugclassesformultidex'. > java.util.zip.zipexception: duplicate entry: android/support/v4/accessibilityservice/accessibilityserviceinfocompatjellybeanmr2.class 

below app dependencies

configurations { all*.exclude group: 'com.android.support', module: 'support-annotations' } dependencies {     compile filetree(dir: 'libs', include: ['*.jar'])     compile project(':waleteros')         compile 'com.android.support:recyclerview-v7:+'        compile 'com.squareup.picasso:picasso:2.4.0'     compile 'com.jakewharton:butterknife:5.1.2'     compile files('src/libs/android_sync_service_library.jar')     compile "com.google.android.gms:play-services:3.1.+"     compile('com.crashlytics.sdk.android:crashlytics:2.2.2@aar') {         transitive = true;     } 

and here library dependencies

configurations { all*.exclude group: 'com.android.support', module: 'support-v4' } configurations { all*.exclude group: 'com.android.support', module: 'support-annotations' } dependencies {     compile project(':ingosdk')     compile 'com.google.code.gson:gson:2.2.4'     compile files('libs/a2ia.mobility.jar')     compile files('libs/acra-4.5.0.jar')     compile files('libs/bugsense-3.5.jar')     compile files('libs/deviceprint-lib-1.0.0.jar')     compile files('libs/flurryanalytics-5.3.0.jar')     compile files('libs/httpmime-4.1.2.jar')     compile files('libs/libgoogleanalyticsservices.jar')     compile files('libs/volley.jar')     compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'     compile files('libs/android-support-v13.jar')  } 

if have android-support-v4.jar in libs folder.. delete it!

that solved problem.

even though file not added in build.gradle file.. gradle includes in build anyway.
