Steps:-
- Open
Eclipse and create a new Android project.
The first thing that we will handle is the import of Google Map classes. To get
the Google Maps files we need to download the last version of Google Play
Services via the Android SDK Manager.
- After
you downloaded the Google Play Services, restart Eclipse and
in the Package Explorer Right-Click –> Import….
In the opened windows choose “Existing Android Code into Workspace” and
click “Next”.
Click the “Browse…” Button and head to the location of your
SDK folder. In it find the following folder: \extras\google\google_play_services\libproject\google-play-services_lib
and press “OK”,
check the V next to it in the window and press the “Finish” button.
- Now you added Google Play Services to
your work space, we have to create a reference
from our project to this library. Right-Click your project and choose “Properties” go
to the Android section, in the lower part press the “Add…” button
and add a reference
to that library. Your result should be as in the screen shot bellow:
Note:
If you try to reference google-play-service library
and you receive a red X next to this reference, what you
should do is to move the .jar file to a location where it’s path will be
shorter and then reference it again.
- Another
import we have to make in order to make our application work on Operation
system prior to API11 is to import the support library this can be done very
easily using Eclipse: Right-Click you project and choose “Android
Tools” and then choose “Add Support Library…”:
When you finish those imports you
should have the following libraries (Red) in the Android
Dependencies folder (Green) of your project:
- We
are now ready for some coding: First of all open the Android Manifest file:
add the following permissions:
<permission android:name="your.application.package.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<uses-permission android:name="your.application.package.permission.MAPS_RECEIVE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Important:
Replace
your application package instead of the current “your.application.package” string.
- Next,
Google Maps uses OpenGL so we have to add OpenGL support to our application
by adding this to the Manifest file:
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
- Finally add your key to you application right
before you close your “application” node
in the Manifest file:
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Your Google Maps API V2 Key" />
- Now create an Activity that
extends from “FragmentActivity”:
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class MapActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_layout);
}
}
- Finally for map_layout,
XML layout file that was set as a content view of the map activity write the
following:
<?xml version="1.0" encoding="utf-8"?>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Steps to getting the Map API Key from the Google Map:
- Select
services for the project. Here we need a Google Maps Android API v2 service. Search this service in list and ON this
service.
- Get
SHA1 Fingerprint form this command
C:\Users\pavan.p>keytool -list -alias androiddebugkey
-keystore default-keystore-file
-storepass android -keypass android
androiddebugkey, Jun 25, 2012,
PrivateKeyEntry,
Certificate fingerprint (SHA1):
67:3C:9D:----Gen SHA1 Key----:E8
In my case:-
default-keystore-file : C:\Users\pavan.p\.android\debug.keystore
Or find it in the Eclipse Window ->
Preferences -> Android -> Build -> here you will found the both SHA1
and MD5 fingerprint.
- Go
to API Access tab from the console. Here we show the one key Key for browser apps (with referrers). We want to get API Key for android
then click on create New Android Key button. The opened dialog asks for SHA1
fingerprint and package name followed by semicolon.
Enter your SHA1 fingerprint and
package name,
In my case input is
67:3C:9D:3B:AB:00:D0:ED:6D:94:28:B9:63:EF:E0:33:32:E7:6D:E8;sample.sample
- Use
this key in the Manifest file:
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Your Google Maps API V2 Key" />
- One
important thing about the Android Google map v2 is , When
your application is in debugging mode the map works fine but when we create
.apk of the application the Google map needs the Release Key for that. With
version 2 API's you can use the same key for release and debug. In your google
api's console edit your allowed android apps and on each line put your debug/release
key, and then your app name. You can use multiple lines, then it will work with
both keys.
- To
export the apk, see the bottom of the manifest file with link as “Use the
Export Wizard”
Follow
all the instructions:-
- When
apk is generated at the same time MD5 fingerprint and SHA1 generated in the
console as follow
- Copy the SHA1 key, go to Google API Console and Click
on Edit allowed Android apps... link, add the SHA1 key in the dialog box with
package name. Make sure that generated the API key and Manifest key is same.
Hope
all the steps helpful to you.
Happy Reading and Happy coding.. :-)
