Hi I get the following exception: 06-10 10:53:36.643: E/AndroidRuntime(10415): java.lang.NoClassDefFoundError: com.applovin.sdk.AppLovinSdk I imported the external lib and also copy pasted the lib to /libs folder. but I still get this error. I imported the lib as : import com.applovin.sdk.AppLovinSdk; and the program falls at this line : AppLovinSdk.initializeSdk(this); . What am I missing?
lines before the error:

project right click properties-> Java BuildPath select Library and add external .jar the follow these step.
Go to Project->Properties->Java Build Path than select Order and export tab. Set external .jar library checked and up it into top of the list. And clean and rebuild..It works for most of the cases

There is a bug in ADT 22. If you use this you have to check the Android Private Libraies in the Order and Export tab in Preferences/Java Build Path.
You can read about this in detail here:
Libraries do not get added to APK anymore after upgrade to ADT 22
