Without error log, it's difficult to fix the issue.
Here is an example. Getting Started with Google MapV2 for Android Apps.

i've put the logcat output into my question – user2735706 Aug 31 '13 at 15:32
@user2735706 you need to use `MapFragment` instead of `SupportMapFragment` – Raghunandan Aug 31 '13 at 15:39

Your meta tag must be a child of application tag.

You need to extend Standard Activity instead of FragmentActivity since you min sdk is not 11 or below

You should use a MapFrament instead of SupportMapFragment.

Remove <uses-library android:name="com.google.android.maps"> </uses-library> from manifest

Make sure you follow all the steps @

i changed the things you told me, but same problem, i've did everithing which is at the google devlopers explained – user2735706 Aug 31 '13 at 15:50
@user2735706 if you followed all the steps then it should work. you might be missing or skipping few steps. you have multiple setContentView in a single activity which is not good. I don't see where you initialize GoogleMap object any where in your code. i guess you are still following the map api v1 style – Raghunandan Aug 31 '13 at 15:53
@user2735706 you don't need this ` ` and follow the steps in the docs and change your activity code – Raghunandan Aug 31 '13 at 15:55
I followed all the steps at that link too, and it didn't help me either:( It took instead a great deal of flailing for me to get the library project for Google Play Services to install correctly (at first, it would not even appear as an option in the dialog to install the Library) and get android-support-v4.jar installed. Once I did all this, the error "Unknown Source" disappeared. The usual cause of this is that the APK does not include the library: the OP may have to move the library by hand into the libs/ directory to fix this. – Matt J. Sep 01 '13 at 01:36
@MattJ. no need to move the library to libs. Google play services is a library project which should be referenced in your android map project. Should no add the jar to your libs folder. – Raghunandan Sep 01 '13 at 01:38

Haven't you read the stack trace? It says clearly:

API key not found. Check that is in the element of AndroidManifest.xml

The API Key you use ("my api debug key (v2) ") in your Manifest file is not valid. You have to create one in the API Console and use that one.
