Android - The API key can only be specified once <meta-data> duplicates

Question

I’m trying to add Google map in to may app, so I have taken the API key. Unfortunately when I inserted the API key in manifest.xml through a meta-data tag, it automatically inserted another meta-data tag at compile time as shown below. Now it generates below mentioned error. The worst case is, even I delete each of them or both, it automatically generates both tags at compile time again and throws the error.

Any help?

Solution

Delete your "com.google.android.maps.v2.API_KEY" meta-data entry.

The "com.google.android.geo.API_KEY" entry is sufficient for both the Maps and Places services.

EDIT - Google updated their documents to explicitly call this out now:

1. https://developers.google.com/places/android-api/start#api-key
2. https://developers.google.com/maps/documentation/android-sdk/signup#use-key

Can you show us the entire manifest file?

[Emil]

Try and remove com.google.android.geo.API_KEY this meta data tag from your manifest. I don't know why its getting regenerated. Are you editing the correct manifest file? (app/src/main/AndroidManifest.xml)

[user2486322]

yes. OMG just now i noticed. in the manifast there is an activity tag for com.exampl.t_collect.activity.MapsActivity which is also auto generating.

[user2486322]

Actually i added a google map activity to my project previously and removed. i think this tag should relevant to that activity.

Have you got the solution ?
