Android Telephony Manager

Android Tutorials for Beginners

 Telephony Manager

Telephony Manager provides access to information about the telephony services on the device. Applications can use the methods in this class to determine telephony services and states, as well as to access some types of subscriber information. Applications can also register a listener to receive notification of telephony state changes.

You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE).

Permission Required: 

To work with Telephony Manager and to read the phone details we need
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>           permission.So  add this permission in  your manifest file.

Accessing the Telephony Manager:

TelephonyManager  telephonyManager=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

Reading Details of your Phone:

int phoneType = telephonyManager.getPhoneType();
switch (phoneType) {
case (TelephonyManager.PHONE_TYPE_CDMA): break;
case (TelephonyManager.PHONE_TYPE_GSM) : break;
case (TelephonyManager.PHONE_TYPE_NONE): break;
default: break;
}


How to Get IMEI number of the Phone

Getting  Network Details

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

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

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

// Get the type of network you are connected with 
int 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;

 

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.

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 code
String simCountry = telephonyManager.getSimCountryIso();
// Get the operator code of the active SIM (MCC + MNC)
String simOperatorCode = telephonyManager.getSimOperator();
// Get the name of the SIM operator
String simOperatorName = telephonyManager.getSimOperatorName();
// -- Requires READ_PHONE_STATE uses-permission --
// Get the SIM’s serial number
String simSerial = telephonyManager.getSimSerialNumber();
}
}

Dialog With CheckBox In Android

We can also add check boxes in Alert Dialog and we can check multiple, it is used when we want mutiple option to be selected.

Handling the Click Events on CheckBoxes:

when a Checkbox is clocked means it is checked or unchecked obClick() method is called and the index of the selected item is passed, we can use this index to get the item which is checked

final CharSequence[] items = {" Easy "," Medium "," Hard "," Very Hard "};
                // arraylist to keep the selected items
                final ArrayList seletedItems=new ArrayList();
              
                AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setTitle("Select The Difficulty Level");
                builder.setMultiChoiceItems(items, null,
                        new DialogInterface.OnMultiChoiceClickListener() {
                 @Override
                 public void onClick(DialogInterface dialog, int indexSelected,
                         boolean isChecked) {
                     if (isChecked) {
                         // If the user checked the item, add it to the selected items
                         seletedItems.add(indexSelected);
                     } else if (seletedItems.contains(indexSelected)) {
                         // Else, if the item is already in the array, remove it
                         seletedItems.remove(Integer.valueOf(indexSelected));
                     }
                 }
             })
              // Set the action buttons
             .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                 @Override
                 public void onClick(DialogInterface dialog, int id) {
                     //  Your code when user clicked on OK
                     //  You can write the code  to save the selected item here
                   
                 }
             })
             .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                 @Override
                 public void onClick(DialogInterface dialog, int id) {
                    //  Your code when user clicked on Cancel
                  
                 }
             });
      
                dialog = builder.create();//AlertDialog dialog; create like this outside onClick
                dialog.show();
        }


here dialog is an Object of AlertDialog and declared ass

Create Option Menu In Android

Option Menu:
Option Menu is a drop down menu containing   options, and appears when a users clicks on Menu button.
For Ex:
 

                                              

We can create an Option Menu with following :

1. Create a menu xml
2. Register the menu in Activity
3. Write code to Handle the Clicks on menu items

1: Create xml for menu

     Create a new folder named "Menu" in res folder
     inside this  Menu folder create .xml    file

here I have created option.xml   xml for the option menu in  above  Image

           <?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
   
     <item android:id="@+id/ChangeColor"
          android:icon="@drawable/setting"
          android:title="Settings"
          />
    <item android:id="@+id/phoneInformation"
          android:icon="@drawable/phone"
          android:title="My Phone Information" />
   
    <item android:id="@+id/callInfo"
          android:icon="@drawable/callinfo"
          android:title="In and Out Call Info" />

   
    <item android:id="@+id/email"
          android:icon="@drawable/mail"
          android:title="Mail to Developer" />
   
 </menu>

android:id

A resource ID that's unique to the item, which allows the application can recognize the item when the user selects it.

android:icon

An image  to use as the item's icon.

android:title

A tittle to show.

2: Register In Activity

Override onCreateOptionMenu   method and inflate the .xml (here options.xml) inside method

            @Override
                     public boolean onCreateOptionsMenu(Menu menu) {
                            MenuInflater inflater = getMenuInflater();
                            inflater.inflate(R.menu.options, menu);
                            return true;
                     }

3: Handle Click Events

When the user selects an item from the options menu (including action items in the action bar), the system calls your activity's onOptionsItemSelected() method. This method passes the MenuItem selected. You can identify the item by calling getItemId(), which returns the unique ID for the menu item (defined by the android:id attribute in the menu resource

 To Handle click events override  onOptionsItemSelected  method


                               @Override
                     public boolean onOptionsItemSelected(MenuItem item) {
                         // Handle item selection
                        
                      
                         switch (item.getItemId()) {
                             case R.id.ChangeColor:
                                                              // write code to execute when clicked on this option
                                                                return true;   

                             case R.id.phoneInformation:
                                                             // write code to execute when clicked on this option
                                                             return true;
                            
                              case R.id.callInfo:
                                                              // write code to execute when clicked on this option
                                                             return true;
                                
                             case R.id.email:
                                                            // write code to execute when clicked on this option
                                                              return true;
                                
                               default:
                                                   return super.onOptionsItemSelected(item);
                         }
                     }

To create a context menu:

1. Register the View to which the context menu should be associated by calling registerForContextMenu() and pass it the View. Here we have used Context Menu with ListView
   
   
2. Implement the onCreateContextMenu() method in your Activity When the registered view receives a long-click event, the system calls your onCreateContextMenu()method. This is where you define the menu items, usually by inflating a menu resource.

1:  Registering The View(here List View)  for Context menu.

We have to register the ListView for ContextMenu in onCreate  method


@Override
            public void onCreate(Bundle savedInstanceState)
            {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.show_contacts);
              
                    listViewSmartContacts=(ListView)findViewById(R.id.listSmartContacts);
                    //getList();
                    contactListAdapter=new ContactListAdapter(this);
                    listViewSmartContacts.setAdapter(contactListAdapter);
       
                    // Register the ListView  for Context menu
                    registerForContextMenu(listViewSmartContacts);
       }

2: Implement the onCreateContextMenu()

When the registered view receives a long-click event, the system calls your onCreateContextMenu() method. 

             @Override
            public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
            {
                    super.onCreateContextMenu(menu, v, menuInfo);
                    menu.setHeaderTitle("Select The Action"); 
                    menu.add(0, v.getId(), 0, "Call"); 
                    menu.add(0, v.getId(), 0, "Send SMS");
    
            } 

MenuInflater allows you to inflate the context menu from a menu resource 

3: Implement onContextItemSelected method



When the user selects a menu item, the system calls this method so you can perform the appropriate action.


             @Override 
            public boolean onContextItemSelected(MenuItem item)
            { 


                        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
                       
               
                
                                if(item.getTitle()=="Call")
                                {
                
                                   // Code to execute when clicked on This Item
                                 } 
                                else if(item.getTitle()=="Send SMS")
                                {
                                   
                                  // Code to execute when clicked on This Item                                    } 
                                else
                                {return false;} 
                                return true; 
                        }
                                   
                  }
