Android MPL package developer Download

Question

I'm building an Android application and i want to integrate it with PayPal payment. I have to download the necessary libraries to use PayPal. PayPal documentation gives a link where choose the SDKs, but installing and using Java's once, the application crashes. LogCat says that

java.lang.NoClassDefFoundError: com.paypal.android.MEP.PayPal

Can anyone explain me which library i have to download and import?

Thanks in advance.

You should make sure the paypal jar is in the libs directory of your project. ProGuard will then process it and include it in the output jar.

With the -libraryjars option, ProGuard will read it, but not include it in the output jar, so you get a NoClassDefFoundError . See the Proguard manual
