Android MapView Permissions and Prerequisites

In uncategorized on 26 October 2008 with 7 comments

Apparently you need the:

<uses-permission android:name=”android.permission.ACCESS_COARSE_LOCATION”></uses-permission>
<uses-permission android:name=”android.permission.ACCESS_FINE_LOCATION”></uses-permission>
<uses-permission android:name=”android.permission.INTERNET”></uses-permission>

in your manifest file. Wasted a day on that INTERNET one! I swear it was working yesterday without it, but today I was just getting a blank map grid.

Other gotchas about MapViews:

  1. In the manifest file, those <uses-permissions> elements should come before your <application> element
  2. In order to define a MapView in an XML layout file, you can’t use a <MapView> element. Instead, you must have a <com.google.android.maps.MapView/> element, and you need to have a android:apiKey attribute in there as well, with a valid android maps api key. Not intuitive.
  3. Activity.findViewById is a very useful function
  4. The only type of Activity that can show maps is a MapActivity

And don’t foreget: if you want to use a MapActivity in your code the following tag is needed in your Manifest.xml:

it belongs INSIDE the tag (right before closing it worked fine for me)

Thank you for this article! I was beating my head against the wall thinking my maps API key wasn’t working when the problem was that my permissions were inside my application element.

Seriously, I wasted a whole stupid day on the same d*** thing. Stupid INTERNET permission. I mean it does make sense that it would be required, but why aren’t those more clearly documented!?

The permissions tags after the application element was the issue for me. Thanks for the specific mention.
Really useful, and helpful.
