Question

I want to show current location in map using Google Map v2. I create sha key and generate API key and also integrate with androidmanifest.xml. I download example of following link:

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          class="com.google.android.gms.maps.SupportMapFragment"/>

</manifest>

Open sdk manager and download google play service under extras, you will get two libraries google-play-services_lib.jar and google-play-services.jar. You can find these libraries under google play service in extras. You have to copy these two libraries and paste under lib folder in your app and also add these libraries under java Build path.

Answer 2

make sure by going to google api console go to services in go down you will find google map v2 eanble it... To add a reference to a library project, follow these steps:

    1. Make sure that both the project library and the application project that depends on it are in your workspace. If one of the projects is missing, import it into your workspace.
    2. In the Package Explorer, right-click the dependent project and select Properties.
    3.In the Properties window, select the "Android" properties group at left and locate the Library properties at right.
    4.Click Add to open the Project Selection dialog.
    5.From the list of available library projects, select a project and click OK.
    6.When the dialog closes, click Apply in the Properties window.
    7.Click OK to close the Properties window.
