Langkah-langkah membuat Google Maps pada Android yaitu sebagai berikut :
Yang pertama yang harus kita lakukan untuk membuat aplikasi ini adalah melakukan Generate Google Maps API Key. Untuk mendapatkan API key kita perlu melakukan generate SHA-1 fingerprint yakni file debug.keystore yang terdapat di direktori C:\Users\Nama_User\.android. menggunakan java keytool. Cara generate kode-nya cukup mudah, kita bisa menggunakan Command Prompt dan mengektikkan kode di bawah ini.
keytool.exe -list -alias androiddebugkey –keystore “C:Users\Nama_user\.android\debug.keystore” -storepass android -keypass android
Jika berhasil langkah selanjutnya adalah
- Buka Link berikut https://code.google.com/apis/console/?noredirect#project:451713360833:overview
- Pilih services dan aktifkan “Google Maps Android API v2″
- Klik “API Acces“
- Pilih “Create New Android Key“
- Lalu masukkan kode SHA1 kita tadi pada kolom yang tersedia lalu Klik Create
- Setelah itu akan ditampilkan Key for Android apps (with certificates)
Setelah melakukan langkah-langkah diatas. Selanjutnya membuat aplikasi baru seperti biasa dengan cara sebagai berikut :
- Membuat Aplikasi Android Project Baru yaitu File – New – Android Application Project. Masukkan nama project yang akan di buat
- Konfigurasi Proyek Aplikasi Android
- Membuat Desain Aplikasi Launcher Icon untuk tampilannya
- Membuat Aktivitas Kosong
- Masukkan Main Rincian Kegiatan
- Edit File AndroidManfiest.xml
<?xml version=”1.0″ encoding=”utf-8″?>
<manifest xmlns:android=”http://schemas.android.com/apk/res/android”
package=”com.example.desimaps”
android:versionCode=”1″
android:versionName=”1.0″ >
<uses-sdk
android:minSdkVersion=”8″
android:targetSdkVersion=”18″ />
<permission
android:name=”com.example.hendramaps.permission.MAPS_RECEIVE”
android:protectionLevel=”signature”/>
<uses-permission android:name=”com.example.desimaps.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_FINE_LOCATION”/>
<uses-feature
android:glEsVersion=”0x00020000″
android:required=”true”/>
<application
android:allowBackup=”true”
android:icon=”@drawable/ic_launcher”
android:label=”@string/app_name”
android:theme=”@style/AppTheme” >
<activity
android:name=”com.example.desimaps.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>
<meta-data
android:name=”com.google.android.maps.v2.API_KEY”
android:value=”YOUR_API_KEY”/>
</application>
</manifest>
- Edit file activity_main.xml untuk menampilkan Google Map menggunakan SupportMapFragment
<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android”
xmlns:tools=”http://schemas.android.com/tools”
android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:paddingBottom=”@dimen/activity_vertical_margin”
android:paddingLeft=”@dimen/activity_horizontal_margin”
android:paddingRight=”@dimen/activity_horizontal_margin”
android:paddingTop=”@dimen/activity_vertical_margin”
tools:context=”.MainActivity” >
<TextView
android:id=”@+id/tv_location”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content” />
<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:layout_below=”@id/tv_location”
class=”com.google.android.gms.maps.SupportMapFragment” />
</RelativeLayout>
- Edit MainActivity.java menjadi sebagai berikut
package com.example.desimaps;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.widget.TextView;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
public class MainActivity extends FragmentActivity implements LocationListener {
GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Getting Google Play availability status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
// Showing status
if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}else { // Google Play Services are available
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
// Enabling MyLocation Layer of Google Map
googleMap.setMyLocationEnabled(true);
// Getting LocationManager object from System Service LOCATION_SERVICE
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
// Creating a criteria object to retrieve provider
Criteria criteria = new Criteria();
// Getting the name of the best provider
String provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location
Location location = locationManager.getLastKnownLocation(provider);
if(location!=null){
onLocationChanged(location);
}
locationManager.requestLocationUpdates(provider, 20000, 0, this);
}
}
@Override
public void onLocationChanged(Location location) {
TextView tvLocation = (TextView) findViewById(R.id.tv_location);
// Getting latitude of the current location
double latitude = location.getLatitude();
// Getting longitude of the current location
double longitude = location.getLongitude();
// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude);
// Showing the current location in Google Map
googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
// Zoom in the Google Map
googleMap.animateCamera(CameraUpdateFactory.zoomTo(15));
// Setting latitude and longitude in the TextView tv_location
tvLocation.setText(“Latitude:” + latitude + “, Longitude:”+ longitude );
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
- Aktifkan GPS dan jalankan aplikasi
