        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }

}

Manifest :

</manifest>

Here is output

Answer 1

try this

http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/

use your api key of v2.

Answer 2

Google map api v1 is officially deprecated, you can not request for new api key to api v1. Only older api keys will work with google map api v1 which is already been created.

So please try to implement Google Map API V2.

Answer 3

There is no Api Key defined in your android manifest. Your map wont load without that. Second, you didn't define all the permissions in your android manifest. OpenGl, that's also a must. Refer to this code. This will help you..:) My Main Activity:

public class MainActivity extends FragmentActivity {

private static final int GPS_ERRORDIALOG_REQUEST = 9001;
Button btn1;
EditText et1;
EditText et2;

GoogleMap map;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (servicesOK()) {
        Toast.makeText(this, "Ready to map!!", Toast.LENGTH_LONG).show();
        setContentView(R.layout.testmap);

    } else {
        setContentView(R.layout.activitymain);

    }

    /*
     * et1 = (EditText)findViewById(R.id.edittext1); et2 =
     * (EditText)findViewById(R.id.edittext2); btn1 =
     * (Button)findViewById(R.id.button1);
     * 
     * btn1.setOnClickListener(this);
     */

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

/*
 * @Override public void onClick(View v) {
 * 
 * Object lat = et1; Object lon = et2;
 * 
 * Uri uri=Uri.parse("geo:"+lat.toString()+","+lon.toString()); Intent i=new
 * Intent(Intent.ACTION_VIEW, uri); startActivity(i); Log.d("The Location:",
 * lat.toString()+lon.toString());
 * 
 * 
 * }
 */
public boolean servicesOK() {

    int isAvailable = GooglePlayServicesUtil
            .isGooglePlayServicesAvailable(this);

    if (isAvailable == ConnectionResult.SUCCESS) {

        return true;

    } else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)) {

        Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable,
                this, GPS_ERRORDIALOG_REQUEST);
        dialog.show();

    } else {

        Toast.makeText(this, "Cant connect!!", Toast.LENGTH_SHORT).show();

    }
    return false;
}

}

My Layout:

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

And finally the Android Manifest. This is the most important think you will have to consider:

package="com.mike.maps"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="18" />

<permission
    android:name="com.mike.maps.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-permission android:name="com.mike.maps.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" >
</uses-feature>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.mike.maps.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="com.mike.maps.SecondActivity" >
    </activity>

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="Your API KEY goes here" >
    </meta-data>
</application>

Answer 4

Note: Version 1 of the Google Maps Android API has been officially deprecated as of December 3rd, 2012. This means that from March 18th, 2013 you will no longer be able to request an API key for this version. No new features will be added to Google Maps Android API v1. However, apps using v1 will continue to work on devices. Existing and new developers are encouraged to use
