Google Maps Android V2 - Blank Screen

Question

I am implementing google maps for android. I created a test application and inserted all the permissions etc in that application and the application worked flawlessly.

Answer 1

2 possible reasons:

1. this part:

 <uses-library android:name="com.google.android.maps"/>
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="my api key"/>

should right before the closing application tag.

2. Most likely you have some sort of problem with your key. Try to generate a new by deleting the debug.keystore folder and running a project. then register it again via the console.

you can use this guide I wrote to do just that:

Google Map API V2 key

Update:

Check this for a second:

<permission      android:name="com.shop.addtask.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>

it looks that the package you set here is not the package of your application and should be:

  <uses-permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE"/>
  <permission      android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>

Answer 2

After everything fails, try to uninstall the app and try it again. It worked in my case.
