Java.lang.NoClassDefFoundError: com.nineoldandroids.view.ViewHelper

Question

I am using daimajia / AndroidImageSlider . I have imported all the dependencies, such as NineOldAndroid, Picasso and this "com.daimajia.slider: library: 1.1.2@aar " and encoded as oriented on Github. but whenever I tried to start the application, it stopped and showed error.my biuld.gradle for the application. Thank you very much. Two days have passed.

dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.android.support:appcompat-v7:22.1.0' compile 'com.squareup.picasso:picasso:2.3.2' compile 'com.daimajia.slider:library: 1.1.2@aar ' compile 'com.android.support:recyclerview-v7:21.0.+' compile files('C:/Users/Vinit/Downloads/Coupan/library/volley.jar') compile files('C:/Users/Vinit/Downloads/Coupan/library/nineoldandroids-2.3.0.jar')} 

I don’t know where and what I am doing wrong. This is my log file.

Answer 1

Finally, two days later I found a solution. I just added:

compile 'com.nineoldandroids:library:2.4.0'

Answer 2

Move all your libraries to the lib folder in the folder of your application in Android studio, and then add its path depending on build.gradle.

for ex -

 compile files('lib/volley.jar') 

Answer 3

Check the libs folder if they are present

Check with the right-click properties in android if your libraries are added correctly when they are in an external library or in the build path if present.
