1 Praktikum X Pokok Bahasan: Membuat Aplikasi Google Map Android Location API Google Map Tujuan Belajar: Setelah mempelajari modul ini mahasiswa diharapkan mengetahui: Cara membuat aplikasi Google Map Mengenal Koordinat pemetaan (Longitude dan Latitude) Teori Dasar Salah satu ciri mobile phone /tablet pc adalah portabilitas, sehingga tidak mengherankan bahwa beberapa fitur android sangat menarik seperti layanan yang memungkinkan anda menemukan, mencari serta menvisualisasikan posisi kita ke dalam peta lokasi fisik (google maps). Percobaan 1: 1. Buat project baru 2. Tambahkan coding berikut pada main.xml <LinearLayout xmlns:android=" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/textview1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="latitude:" android:textsize="20dip"/> <TextView android:id="@+id/txtlat" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="" />

2 <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="longitude:" android:textsize="20dip"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="" /> </LinearLayout> 3. Tambahkan coding dibawah pada file activity: package com.locationapi; import android.location.criteria; import android.location.location; import android.location.locationlistener; import android.location.locationmanager; import android.os.bundle; import android.widget.textview; import android.widget.toast; import android.app.activity; import android.content.context; public class LokasiActivity extends Activity implements LocationListener { private TextView latitutefield; private TextView longitudefield; private LocationManager locationmanager; private String protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.main); latitutefield = (TextView) findviewbyid(r.id.txtlat);

3 longitudefield = (TextView) findviewbyid(r.id.txtlong); locationmanager=(locationmanager) getsystemservice(context.location_service); Criteria criteria = new Criteria(); provider = locationmanager.getbestprovider(criteria, false); Location location = locationmanager.getlastknownlocation(provider); if (location!= null) { System.out.println("Provider " + provider + " has been selected."); onlocationchanged(location); else { latitutefield.settext("lokasi tidak tersedia"); longitudefield.settext("lokasi tidak tersedia"); protected void onresume() { super.onresume(); locationmanager.requestlocationupdates(provider, 400, 1, this); protected void onpause() { super.onpause(); public void onlocationchanged(location location) { // TODO Auto-generated method stub float lat = (float) (location.getlatitude()); float lng = (float) (location.getlongitude()); latitutefield.settext(string.valueof(lat)); public void onproviderdisabled(string provider) { // TODO Auto-generated method stub Toast.makeText(this, "Disabled provider " + provider, Toast.LENGTH_SHORT).show();

4 @Override public void onproviderenabled(string provider) { // TODO Auto-generated method stub Toast.makeText(this, "Enabled new provider " + provider, public void onstatuschanged(string provider, int status, Bundle extras) { // TODO Auto-generated method stub 4. Tambahkan 3 uses-permission berikut pada AndroidManifest.xml: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android=" package="com.locationapi" android:versioncode="1" android:versionname="1.0" > <uses-permission android:name="android.permission.access_coarse_location" /> <uses-permission android:name="android.permission.access_fine_location" /> <uses-permission android:name="android.permission.internet" /> <uses-sdk android:minsdkversion="8" android:targetsdkversion="17" /> <application android:allowbackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/apptheme" > <activity android:name="com.locationapi.lokasiactivity" 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> </manifest>

5 5. Pilih DDMS > Emulator Control > ubah nilai Longitude dan Latitude > klik Send > amati perubahan yang terjadi pada emulator.

6 Percobaan 2: Persiapan Device 1. Install Google Play Service pada Android SDK manager 2. Import project yang berada dalam sdk\extras\google\google_play_services\libproject Dengan cara File > Import > adroid > Existing android project into workspace > browse > pilih folder libproject tersebut. 3. Buka command prompt dan ketik: keytool -list -v -alias androiddebugkey -keystore C:\Users\<nama user>\.android\debug.keystore - storepass android -keypass android

7 4. Buka pilih services dan aktifkan Google Maps Android API v2. 5. Pilih API Access > Create new Android key

8 6. Isi kode SHA1 yang terdapat pada cmd beserta nama package project yang akan dibuat. 7. Jalankan Android Virtual Device dan install google play service melalui cmd setelah AVD selesai booting:

9 Pembuatan Program 1. Buat android project baru: 2. Tambahkan Project library yang telah didownload.

10 3. Activity_Main.xml <RelativeLayout xmlns:android=" xmlns:tools=" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".mapactivity" > <fragment android:name="com.google.android.gms.maps.mapfragment" android:layout_width="match_parent" android:layout_height="match_parent" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:onclick="onclick_unsada" android:text="unsada" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparenttop="true" android:layout_centerhorizontal="true" android:layout_margintop="14dp" android:onclick="onclick_rsj" android:text="rsj" /> <Button android:layout_width="wrap_content"

11 android:layout_height="wrap_content" android:onclick="onclick_ragunan" android:text="ragunan" /> </RelativeLayout> 4.
