Java.lang.noclassdeffounderror: Com.google.android.gms.r$styleable (project Added!!)

this is kinda a newbie question, but I'm having this problem even following the Google guides. My app is crashing when seeing a map, with this throw: java.lang.NoClassDefFoundErro

Solution 1:

It seems everything is fine in your code, Do following:

1. clean and build and

2. then first uninstall and then install the app.

And see if it works.
