What's Google Maps?

Google Maps (formerly Google Local) is a web mapping service
application and technology provided by Google, free (for non-
commercial use), that powers many map-based services, including the
Google Maps website, Google Ride Finder, Google Transit,[1] and maps
embedded on third-party websites via the Google Maps API.[2] It offers
street maps, a route planner for traveling by foot, car, or public
transport and an urban business locator for numerous countries around
the world. Google Maps satellite images are not in real time; they are
several years old.[3]

Android is an Open Source project?
Android is a mobile operating system initially developed by Android Inc. Android
was bought by Google in 2005.[5] Android is based upon a modified version of
the Linux kernel. Google and other members of the Open Handset Alliance
collaborated on Android's development and release.[6][7] The Android Open
Source Project (AOSP) is tasked with the maintenance and further
development of Android.[8]

…

With the exception of brief update periods, Android has been available under
a free software / open source license since 21 October 2008. Google
published the entire source code (including network and telephony stacks)[33]
under an Apache License.[34] Google also keeps the reviewed issues list
publicly open for anyone to see and comment.[35]

Google Maps is an Android module?

The Google apps for Android, such as YouTube, Google Maps and Navigation,
Gmail, and so on are Google properties that are not part of Android, and are
licensed separately. Contact android-partnerships@google.com for inquiries
related to those apps.

… so?
Google APIs Add-On is an extension to the Android SDK
development environment that lets you develop applications for devices that
include Google's set of custom applications, libraries, and services. A central
feature of the add-on is the Maps external library, which lets you add powerful
mapping capabilities to your Android application.

The add-on also provides a compatible Android system image that runs in the
Android Emulator, which lets you debug, profile, and test your application before
publishing it to users. The system image includes the the Maps library and other
custom system components that your applications may need, to access Google
services (such as Android C2DM). The add-on does not include any custom
Google applications. When you are ready to publish your application, you can
deploy it to any Android-powered device that runs a compatible
version of the Android platform and that also includes the
custom Google components, libraries, and services.

OpenStreetMap (OSM) is a collaborative project to

The maps are created using data from portable GPS
devices, aerial photography, other free sources or
simply from local knowledge. Both rendered images

Steps
1. Obtaining a Maps API key
2. Adding the lib and the permission to your Manifest
3. Displaying the map
4. Displaying the Zoom View

#CatDroid

Obtaining a Maps API key
Beginning with the Android SDK, you need to apply for a free Google Maps
API key before you can integrate Google Maps into your Android
application. To apply for a key, you need to follow the series of steps
outlined below. You can also refer to Google's detailed documentation on
the process at http://code.google.com/android/toolbox/apis/mapkey.html.

First, if you are testing the application on the Android emulator, locate the
SDK debug certificate located in the default folder of "C:Documents and
Settings<username>Local SettingsApplication DataAndroid". The
filename of the debug keystore is debug.keystore. For deploying to a real
Android device, substitute the debug.keystore file with your own keystore
file.
For simplicity, copy this file (debug.keystore) to a folder in C: (for example,
create a folder called "C:Android").

http://developer.android.com/resources/tutorials/views/hello-mapview.html
#CatDroid


Simplified translation:

Find “debug.keystore” file inside your “Documents and Settings” path.

#CatDroid


Using the debug keystore, you need to extract its MD5
fingerprint using the Keytool.exe application included with your
JDK installation. This fingerprint is needed to apply for the free
Google Maps key. You can usually find the Keytool.exe from the
"C:Program FilesJava<JDK_version_number>bin" folder.

#CatDroid


Simplified translation:

Find “Keytool.exe” file inside your JRE/JDK path, probably placed at
“Program Files”.

#CatDroid

Call the following command to extract the MD5 fingerprint.

keytool.exe -list -alias androiddebugkey
-keystore "C:androiddebug.keystore"
-storepass android -keypass android

http://mobiforge.com/developing/story/using-google-maps-android
#CatDroid


Copy the MD5 certificate fingerprint and navigate your web browser to:

http://code.google.com/android/maps-api-signup.html

Follow the instructions on the page to complete the application and obtain the
Google Maps key.

#CatDroid

Editing AndroidManifest.xml

To use the Google Maps in your Android application, you need
to modify your AndroidManifest.xml file by adding the <uses-
library> element together with the INTERNET permission:
<…>
<application android:icon="@drawable/icon" android:label="@string/app_name">
<uses-library android:name="com.google.android.maps" />
<activity android:name=".MapsActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
</...>

#CatDroid

Displaying the Map
To display the Google Maps in your Android application, modify the
main.xml file located in the res/layout folder. You shall use the
<com.google.android.maps.MapView> element to display the Google
Maps in your activity. In addition, let's use the <RelativeLayout> element to
position the map within the activity:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<com.google.android.maps.MapView
android:id="@+id/mapView"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="0l4sCTTyRmXTNo7k8DREHvEaLar2UmHGwnhZVHQ"
/>
</RelativeLayout>

#CatDroid

Displaying the Map
In the MapsActivity.java file, modify the class to extend from the
MapActivity class, instead of the normal Activity class:

package net.learn2develop.GoogleMaps;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;

public class MapsActivity extends MapActivity
{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}

#CatDroid

Displaying the Zoom View
First, add a <LinearLayout> element to the main.xml file as shown below:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent">
<com.google.android.maps.MapView
android:id="@+id/mapView"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="0l4sCTTyRmXTNo7k8DREHvEaLar2UmHGwnhZVHQ"
/>
<LinearLayout android:id="@+id/zoom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>

#CatDroid

In the MapsActivity.java file, add the following imports:
import com.google.android.maps.MapView.LayoutParams;
import android.view.View;
import android.widget.LinearLayout

...and add the following code after the line setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.mapView);
LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);
View zoomView = mapView.getZoomControls();

zoomLayout.addView(zoomView,
new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
mapView.displayZoomControls(true);

#CatDroid

Alternatively, you can also programmatically zoom in or out of the map
using the zoomIn() and zoomOut() methods from the MapController
class:
public class MapsActivity extends MapActivity {
MapView mapView;

public boolean onKeyDown(int keyCode, KeyEvent event) {
MapController mc = mapView.getController();
switch (keyCode) {
case KeyEvent.KEYCODE_3:
mc.zoomIn();
break;
case KeyEvent.KEYCODE_1:
mc.zoomOut();
break;
}
return super.onKeyDown(keyCode, event);
}

// … the rest of the class
