6

Telephony Manager

o Get IMEI Number of Phone

String IMEINumber=tm.getDeviceId();

o Get Subscriber ID

String subscriberID=tm.getDeviceId();

o Get SIM Serial Number

String SIMSerialNumber=tm.getSimSerialNumber();

o Get Network Country ISO Code

String networkCountryISO=tm.getNetworkCountryIso();

o Get SIM Country ISO Code

String SIMCountryISO=tm.getSimCountryIso();

7

Accessing the Telephony Manager

o Get the device software version

String softwareVersion=tm.getDeviceSoftwareVersion()

o Get the Voice mail number

String voiceMailNumber=tm.getVoiceMailNumber();

o Get the Phone Type CDMA/GSM/NONE/ /Get the type of network you are connected with

int phoneType=tm.getPhoneType();

switch (phoneType){

case (TelephonyManager.PHONE_TYPE_CDMA):// your code

break;case (TelephonyManager.PHONE_TYPE_GSM)

// your codebreak;

case (TelephonyManager.PHONE_TYPE_NONE):// your code

break;}

o Get the SIM state/Details

int SIMState=tm.getSimState();switch(SIMState){

case TelephonyManager.SIM_STATE_ABSENT :// your codebreak;

case TelephonyManager.SIM_STATE_NETWORK_LOCKED :// your codebreak;

case TelephonyManager.SIM_STATE_PIN_REQUIRED :// your codebreak;

case TelephonyManager.SIM_STATE_PUK_REQUIRED :// your codebreak;

case TelephonyManager.SIM_STATE_READY :// your codebreak;

case TelephonyManager.SIM_STATE_UNKNOWN :// your codebreak;

}10


o Getting SIM Details :Using the Object of Telephony Manager class we can get the details like SIM Serial number, Country Code, Network Provider code and other Details.

11

int simState = telephonyManager.getSimState();switch (simState){

case (TelephonyManager.SIM_STATE_ABSENT): break;case (TelephonyManager.SIM_STATE_NETWORK_LOCKED): break;case (TelephonyManager.SIM_STATE_PIN_REQUIRED): break;case (TelephonyManager.SIM_STATE_PUK_REQUIRED): break;case (TelephonyManager.SIM_STATE_UNKNOWN): break;case (TelephonyManager.SIM_STATE_READY):{

// Get the SIM country ISO codeString simCountry = telephonyManager.getSimCountryIso();// Get the operator code of the active SIM (MCC + MNC)

String simOperatorCode = telephonyManager.getSimOperator();// Get the name of the SIM operatorString simOperatorName = telephonyManager.getSimOperatorName();// -- Requires READ_PHONE_STATE uses-permission --// Get the SIM’s serial numberString simSerial = telephonyManager.getSimSerialNumber();

}}


o Getting Network Details

// Get connected network country ISO codeString networkCountry = telephonyManager.getNetworkCountryIso();

// Get the connected network operator ID (MCC + MNC)String networkOperatorId = telephonyManager.getNetworkOperator();

// Get the connected network operator nameString networkName = telephonyManager.getNetworkOperatorName();

// Get the type of network you are connected withint networkType = telephonyManager.getNetworkType();switch (networkType){case (TelephonyManager.NETWORK_TYPE_1xRTT) :" Your Code ":break;case (TelephonyManager.NETWORK_TYPE_CDMA) :" Your Code ":break;case (TelephonyManager.NETWORK_TYPE_EDGE) : " Your Code ":break;case (TelephonyManager.NETWORK_TYPE_EVDO_0) :" Your Code ":break;

12


o Find whether the Phone is in Roaming, returns true if in roaming

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

16

<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.example.incomingcallreciever"android:versionCode="1"android:versionName="1.0" >

<uses-sdkandroid:minSdkVersion="8"android:targetSdkVersion="16" />

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" >

<receiver android:name=".IncommingCallReceiver" android:enabled="true"><intent-filter>

public class IncommingCallReceiver extends BroadcastReceiver {Context mContext;

@Overridepublic void onReceive(Context mContext, Intent intent) {

try{

String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){

Toast.makeText(mContext, "Phone Is Ringing", Toast.LENGTH_LONG).show();// Your Code

}if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){

SMS ManagerA very useful feature in Android is the SmsManager API which you can use to send an SMS from inside your own Application. Actually there are two way you can send an SMS from your Application:

Using SmsManager API Using the build in SMS activity of Android API

o Using the built in Application is fairly easy, because you don’t have to do anything special really. You just have to call the built in Activity.

o But using the SmsManagerAPI, you can customize your own Activity the way you want and use it in any manner you choose, so it’s much more flexible. So, in this tutorial we are going to examine both ways.

22

1. Using the build in SMS activity of Android API

Using the built in Application is fairly easy, because you don’t have to do anything special really. You just have to call the built in Activity.

23

Intent smsIntent = new Intent(Intent.ACTION_VIEW);smsIntent.putExtra("sms_body", “Hello sisoft");smsIntent.setType("vnd.android-dir/mms-sms");startActivity(smsIntent);

2.Using SmsManager API

• But using the SmsManagerAPI, you can customize your own Activity the way you want and use it in any manner you choose, so it’s much more flexible. So, in this tutorial we are going to examine both ways.

24

SmsManager smsManager = SmsManager.getDefault();smsManager.sendTextMessage(phoneNo, null, sms, null, null);

Example 1: Send an SMS using the SmsManager APICreate the main Layout of the Application : Open res/layout/main.xml file :

25

• And paste the following code in order to set the appropriate SMS permission for the Application

26

Example 1: Send an SMS using the SmsManager API

Go to the java file that contains the code of the activity you’ve just created

27

Example 1: Send an SMS using the SmsManager API

Example 2: Send an SMS using the Built-in SMS application

1. Create the main Layout of the Application

Open res/layout/main.xml file :

28

Example 2: Send an SMS using the Built-in SMS application• Go to the java file that contains the code of the activity you’ve just created:
