Google Maps V2 shows blank screen on android 2.2

Question

I tried following a tutorial on Android Maps V2 Quick Start But when I run the app, a blank map screen is shown. My phone uses android 2.2.1.

Answer 1

I had the same problem but solved it like that. Might be helpful if the above answer doesn't work for you. After I changed my app's package name, map starts not to show up. (it happened after I changed my package name)

1. Delete the keystore file that you used for previous package
2. Create a new keystore file
3. Get SHA1 fingerprint
4. Go to API Console
5. Create a new Android App.
6. Paste your fingerprint
7. Use the given API Key in your Manifest File

That worked for me
