@integer/google_play_services_version

Problem：

When upgrading my project to the latest version of Google Play Services (v4.0, released on Halloween 2013), you are now supposed to add a new tag into the AndroidManifest.xml file.

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
Unfortunately, when I try doing that, I then get this compile error:

android-apt-compiler: /blahblah/AndroidManifest.xml:409: error: Error: No resource found that matches the given name (at 'value' with value '@integer/google_play_services_version').
I can then navigate to the file at google-play-services_lib/res/values/version.xml and view the raw integer for that symbol:

<integer name="google_play_services_version">4030500</integer>
And then insert it back into my AndroidManifest.xml:

<meta-data
    android:name="com.google.android.gms.version"
    android:value="4030500" />
Doing this works absolutely fine and I can then compile and run the project and app just fine. But it's definitely an undesirable fix with obvious upgradability issues.

解决：

So for everyone using eclipse, this is how it's done:

Eclipse -> import -> existing android code -> browse -> navigate to google-play-services_lib FOLDER (android-sdk/extras/google/google_play_services/libproject).

then, on your project, control click -> properties -> android -> libraries, add -> select the project you just imported -> ok
