问题
I hope I don't get a down vote, English is not my first language that is why I get confused by api documentations. I am confused if I need to generate different api keys for "Google Maps Android API" and "Google Places API for Android"
I am asking because I am sucessfully rendering maps from my android app using google maps android api but when I try the using the code of the official google android places api example (PLACE PICKER) it is failing without throwing any errors. It renders the activity properly but when I click the find places button it just returns me to my previous activity with no error. I am guessing it might be an api key issue that is why I am asking if I need two different api keys for this?
回答1:
No, each service (Google Maps V2 API and Google Places API) have a and will generate a different API Key. But you can't use/declare both keys in your manifest in the same time. When you are using Google Maps and Google Places just use the Google Places API key only (com.google.android.geo.API_KEY), and it will work for both.

Look at this link at android developers https://developers.google.com/places/android-api/signup#release-cert
You need an Android API key, not a browser key. You can use the same API key for your Google Maps Android API v2 apps and your Google Places API for Android apps.
