level 3 @ android camp @ devent 3 by amar ashour

1. Level 3
android camp

2. Maps ,
Location-based Services
&
Telephony API

4. The location-based services facility in Android sits on two pillars:
1-mapping using the package com.google.android.maps,
2-Location-based APIs.using the package android.location
APIs

5. All we need to start is :
1-Internet connection
2-accept the terms of google
Then , let's develop :D

6. Understanding the Mapping
Package
 Obtain your MD5 fingerprint
 Obtaining a map­api Key from Google (two keys) one for
development with the emulator and another for production
 Understanding MapView and MapActivity

7. Let's get our MD5
 locate your debug certificate

8. Let's get our MD5
keytool -list -alias androiddebugkey -keystore
"FULL PATH OF YOUR debug.keystore FILE" -storepass android -keypass android
Enter the password : android
(only if asked)

9. Get your API-key now
 Use the link http://code.google.com/android/maps­
api­signup.html
 Then enter your MD5 and accept the terms

10. Now let's code :D

11. Now let's code :D
mainfest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ashour.amar.map3"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<uses-library android:name="com.google.android.maps" />
<activity
android:label="@string/app_name"
android:name=".Map3Activity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

12. Now let's code :D
add this at your layout
<com.google.android.maps.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:apiKey="0HjFnVeWB501OoE879ht4U35shuIsabH6M5UUUw"
android:clickable="true" />

13. Now let's code :D
javaActivity
public class Map2Activity extends MapActivity{
private MapView mapView;
private GeoPoint pt;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapView = (MapView)findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
}
@Override
protected boolean isLocationDisplayed() {
return true;
}
@Override
protected boolean isRouteDisplayed() {
return true;
}
}

14. TELEPHONY API
With the telephony API you can work with messages , make
calls and use the Internet to make calls VOIP

15. Now let's make SMS sender
app :D

16. Send messages
 You will use android.telephony.SmsManager class
 Dont forget to add the permission
android.permission.SEND_SMS

17. Sms code
layout code
<?xml version="1.0" encoding="utf-8"?>
<!-- This file is /res/layout/main.xml -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

setContentView(R.layout.main);
}
public void doSend(View view) {
EditText addrTxt = (EditText) findViewById(R.id.addrEditText);
EditText msgTxt = (EditText) findViewById(R.id.msgEditText);
try {
sendSmsMessage(addrTxt.getText().toString(), msgTxt.getText()
.toString());
