WearableListView ClassNotFoundException Support v4 ArrayMap

Ok this is a fun one: I'm using Android Studio 1.1.0, I have an Android app and a correlating Android Wear app i'm trying to test on a smart watch device. I've placed the class files I used in my Android app into an Android library module then added it as a dependency into my Android Wear app. The app builds and deploys onto the smart watch but when it runs I get the below exception and stack trace. Any suggestions would be appreciated. Thank you!

Solution

  • I saw this java.lang.ClassNotFoundException: android.support.v4.util.ArrayMap in your logcat trace. And I think maybe the version of your v4 and v7 cause this error. Is your support library of v4 and v7 is up to date? And BTW, ArrayMap only could be used for Android API 21+
