Could Not Find Method Excpetion / Noclassdeffounderror (for External Library) But Not On All Devices

I'm getting an exception like following: 07-26 10:17:25.991 I/dalvikvm(20751): Could not find method org.slf4j.LoggerFactory.getILoggerFactory, referenced from method com.app.andro

Solution 1:

It looks like you have reached the 65k method limit.

try adding this line:

android:name="android.support.multidex.MultiDexApplication"

on AndroidManifest inside application tag

Note that you can avoid this programatically also: Refer to Apps with Over 64K Methods for more details
