Answer 1

Are you sure you have enabled "Google Maps Android API v2" and not "Google Maps API v2"? After changing that, delete and recreate the API key. This worked for me...

Answer 2

Try right click on your project and select Properties > Android > and in "Project Build target" select Google APIs. That worked for me :)

Answer 3

If you are sure about your API key, you should uninstall program from your phone and install again. It worked for me :)

Answer 4

Have u enable Google android map API v2 in console check It properly . I think u enable Google map v2 that why request failed...

Answer 5

You should check if you have duplicate API_KEY for the same project. As you know, we will use sha1 key and android project name for getting an API key. If you try to use same sha1;android_project_name pair to get API key, Google will give you another API key. So its duplicated. If you delete the newer one and use the older one in your project, it will solve your problem. At least I hope :)

Answer 6

I had this problem when refactoring and changing my project bundle identifier. If is this your case, you will have to create a new project on Google Developer Console and link again to your project. For some reason Google blocks requests from the same app if it changes its ID.
