Using a Google Maps API v2

Question

I want to make an app that uses Google Maps Android API V2. So I searched the Internet about tutorials and I found a lot of useful tutorials. In the tutorials they said that, to use Google Maps Android API V2 I have to get a a Google Maps API key. Ok so far so good.

My question is

• Will this key work on multiple phones using my app ?
• Do I have to create an individual Google Maps API key for each new phone that downloads my app from the store ?

Answer 1

Will this key work on multiple phones using my app?

Yes, One Application with proper Map-Key can works on many devices. You dont need to create device wise map-key.

Do I have to create an individual Google Maps API key for each new phone that downloads my app from the store?

No. One Key is enough.
