Development issue/problem:

I get the following exception when I try to use the Google Play Services V2 library after studying the official instructions.

on (Unknown source)
on (Unknown Source)
on (Unknown Source)

What have I done wrong?

How can I solve this problem?

Solution 1:

Version 2 contains resources and should be imported as a library project. See for instructions on how to act in the various IDEs.

The sources are for GooglePlayServicesUtil.getErrorDialog(), which commands the user to install, update, activate, etc. Google Play services if they are not available on your device.

Solution 2:

I had the same problem once, I followed this step and was able to solve it.

First (Configure your project using the Google Developer Console)
Go to the API Console – Google Code

Creating a project As shown in Figures

Once you have created your project, it is time to choose the service we need, in this case we need android map v2, so choose Google Maps PI v2 of the service As shown, enter the description of the image here .

Now go to Api Access and create your OAuth 2.0. Enter the name of your package and your SHA1 fingerprint in the appropriate fields.

Now create an Android project with the same package name as OAuth 2.0. and check if you have the Google Play service in the Android SDK manager, if not, install the Google Play service.

After installing the Google Play service, you can find the Google Play library in your Android YourSdkpathextrasgoogle_play_services.import this project into your workspace and enter it as a reference library for your project

The MainActivity public class expands FragmentActivity {
GoogleMap googleMap ;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState) ;
setContentView(R.layout.activity_main) ;

// Get status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext() ) ;

// Show status
SupportMapFragment supportMapFragment = (SupportMapFragment)

// get map reference cegoogleMap = supportMapFragment.getMap();}more

int requestCode = 10;
Dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);;

@General Boolean menu
onCreateOptionsMenu(Menu) {

getMenuInflater().inflate(, menu);
return true;




I hope this helps you

Solution 3:

For Android Studio :

1) Open the module parameters :

2) Add (import) the google_play_service_lib module of the SDK.

3) The module google_play_service_lib is marked as library.

4) Add the google_play_service.jar library of the SDK.

5) Exit.

Solution 4:

If you have already updated the SDK and received such an error, you should take this into account:

  • Use the new version of google-play-services.jar if you have copied this file in your Eclipse project.
  • set target=android-19 in the project properties.
  • For the newer API (I use API 19) you may need to add the following code


I also use our Google Sdkpathextrasgoogle game services as an eclipse import library, as described above.

I fixed this bug by checking the Copy projects to workspace when importing libraries from Google Play services.

Solution No 7:

I have the same problem with Android Studio when I create a project without Gradle.
The package name in AndroidManifest.xml may cause a problem in the GooglePlayService project.
It must be

The problem arises when I add the library project as a new module instead of as an import module.

Give here a description of the image

When you select New Module, Android Studio displays a dialog box asking you to enter the name of the module and the name of the package. By default, the package name looks like com.example.MODULE_NAME_SPECIFY, which is incorrect. It is very easy to ignore it because the project has been successfully built.

If you add a library project via the import module, everything should go well, because Android Studio simply adds the project without making any changes to the source code of the project library.

Solution No 8:

I’m also facing the same problem. If you run the application in an emulator, this error may occur because most emulators do not have Google PlayService (Play Store application) installed.

So try running your application on an Android device that has the PlayService application installed.

Solution: – Put the code of the error part in try…catch and then try it and it will also work in the emulator.

Note :- The Google mail service requires palliation services, otherwise the error SERVICE_NOT_AVAILABLE will be issued.

Good luck!
