I followed below tutorial,

https://developers.google.com/maps/documentation/android/start#installing_the_google_maps_android_v2_api

I did below things

1. Install Google Play services
2. Created a new app in Google Console, and got Google Map API key
3. Created new app in eclipse and added permission and Google Map API key in AndroidManifest.xml
4. Added Google Play Services library to App
5. Add a Map to the App (main.xml)
6. Set targeted API level 17

in my main.xml

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

here is my complete source code https://github.com/railskarthi/MapDemo

Answer 1

I have download your project from git and after checking i found that you have missed a line which is required to display map Fragment.

Replace your main activity code with the following code:-

public class MainActivity extends FragmentActivity {
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();
}

Answer 2

After API 11+, I think you now have have to replace your MapFragment by SupportMapFragment. It would be something like:

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

Take a look here for further information. Let me know how are you going with.

Answer 3

This could happen also if you did not define API_KEY for google maps in your manifest file.

It looks like this:

`....
<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="<your key>" />
....`

Create your key in Google Developer Console

Answer 4

Please add these line in your manifest file

     <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

    <!-- Goolge API Key -->
     <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="your Goolge API key" />
