问题
I'm new to android dev :)
I'm trying to create a simple app: an activity with a map. I connected my HTC 1x to the computer and when I try to run the app (via intellij IDEA), it crashes.
I have searched for the net (and stackoverflow) for clues and couldn't find any. For example:
- Google Maps v2 - Error
- google map - runtimeexception - error inflating class fragment
Can you please tell me why??
Thanks,
Omer

回答1:
Have you included the Google Play Services library in your project? Without it, critical resources are unavailable. See question: java.lang.noclassdeffounderror: com.google.android.gms.R$styleable for more detail.
