I want to develop a missed call detector .Which notify through broadcast reciver I found the code from the following link
public abstract class PhoneCallReceiver extends BroadcastReceiver {
static CallStartEndDetector listener;
#Override
public void onReceive(Context context, Intent intent) {
savedContext = context;
if(listener == null){
listener = new CallStartEndDetector();
}
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
}
public class CallStartEndDetector extends PhoneStateListener {
int lastState = TelephonyManager.CALL_STATE_IDLE;
boolean isIncoming;
public PhonecallStartEndDetector() {}
//Incoming call- IDLE to RINGING when it rings, to OFFHOOK when it's answered, to IDLE when hung up
//Outgoing call- from IDLE to OFFHOOK when dialed out, to IDLE when hunged up
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
if(lastState == state){
//No change
return;
}
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
isIncoming = true;
//incoming call started
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
//Transition of ringing->offhook are pickups of incoming calls. Nothing down on them
if(lastState != TelephonyManager.CALL_STATE_RINGING){
isIncoming = false;
//outgoing call started
}
break;
case TelephonyManager.CALL_STATE_IDLE:
//End of call(Idle). The type depends on the previous state(s)
if(lastState == TelephonyManager.CALL_STATE_RINGING){
//toast here for missed call
}
else if(isIncoming){
//incoming call ended
}
else{
//outgoing call ended
}
break;
}
lastState = state;
}
}
}
The above code woking fine .But when i got the missed call from same no it repeat the missed call detection . How i will got the toast only once please help
Hi everyone I have got the solution now its working fine with missed call.
Here my Class code MyCallListener extended by BroadcastReciever
private static boolean ring=false;
private static boolean callReceived=false;
private String callerPhoneNumber;
private Context saveContext;
#Override
public void onReceive(Context mContext, Intent intent)
{
saveContext=mContext;
// Get the current Phone State
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state==null){
return;
}
Bundle bundle = intent.getExtras();
number= bundle.getString("incoming_number");
Calendar calendar=Calendar.getInstance();
currentTimeStamp=calendar.getTimeInMillis();
// If phone state "Rininging"
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
ring =true;
// Get the Caller's Phone Number
}
// If incoming call is received
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
callReceived=true;
}
// If phone is Idle
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
// If phone was ringing(ring=true) and not received(callReceived=false) , then it is a missed call
if(ring==true&&callReceived==false)
{
Toast.makeText(mContext, "missed call : "+number, Toast.LENGTH_LONG).show();
//workingWithFunctions();
ring=false;
}
callReceived=false;
}}
dont forgot to define receiver in manifest file
<receiver android:name="com.abc.broadcastrecivers.MyBroadcastReciver" />
in the application tag
public class callServiceReceiver extends BroadcastReceiver
{
TelephonyManager telephonyManager;
#Override
public void onReceive(Context context, Intent intent)
{
phoneStateListener phoneListener = new phoneStateListener(context);
telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
}`enter code here`
public void onDestroy() {
telephonyManager.listen(null, PhoneStateListener.LISTEN_NONE);
}
}
public class phoneStateListener extends PhoneStateListener
{
private Context mContext;
private static boolean ringing =false;
private static boolean call_received =false;
//Constructor
public phoneStateListener(Context context)
{
mContext = context;
}
#Override
public void onCallStateChanged(int state, String incomingNumber)
{
super.onCallStateChanged(state, incomingNumber);
try
{
switch (state)
{
case TelephonyManager.CALL_STATE_RINGING:
ringing = true;
// Get the Caller's Phone Number
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
call_received =true;
break;
case TelephonyManager.CALL_STATE_IDLE:
// If phone was ringing(ringing=true) and not received(call_received=false) , then it is a missed call
if(ringing ==true&& call_received ==false)
{
Toast.makeText(mContext, "missed call : "+incomingNumber, Toast.LENGTH_LONG).show();
ringing =false;
}
call_received =false;
break;
}
}catch (Exception e)
{
e.printStackTrace(System.err);
}
}
}
<receiver android:name=".callServiceReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>

My app is has a simple service, i need to pause that service when user makes or receive a call and service has to resume after call has ended.
Here is my Main Activity looks like:-
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(getApplicationContext(), MyService.class);
startService(intent);
TelephonyManager TelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
TelephonyMgr.listen(new TeleListener(),
PhoneStateListener.LISTEN_CALL_STATE);
}
class TeleListener extends PhoneStateListener {
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
Toast.makeText(getApplicationContext(), "CALL_STATE_IDLE",
Toast.LENGTH_LONG).show();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Toast.makeText(getApplicationContext(), "CALL_STATE_OFFHOOK",
Toast.LENGTH_LONG).show();
break;
case TelephonyManager.CALL_STATE_RINGING:
Toast.makeText(getApplicationContext(), incomingNumber,
Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(), "CALL_STATE_RINGING",
Toast.LENGTH_LONG).show();
break;
default:
break;
}
}
}}
Here is my Service class file:-
public class MyService extends Service {
private static final String TAG = "MyService";
private boolean isRunning = false;
#Override
public void onCreate() {
Log.i(TAG, "Service onCreate");
isRunning = true;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(TAG, "Service onStartCommand");
new Thread(new Runnable() {
#Override
public void run() {
for (int i = 0; i < Integer.MAX_VALUE; i++) {
try {
Thread.sleep(1000);
} catch (Exception e) {
}
if (isRunning) {
Log.i(TAG, "Service running");
}
}
stopSelf();
}
}).start();
return Service.START_STICKY;
}
#Override
public IBinder onBind(Intent arg0) {
Log.i(TAG, "Service onBind");
return null;
}
#Override
public void onDestroy() {
isRunning = false;
Log.i(TAG, "Service onDestroy");
}}
From the TeleListener class in MainActivity i'm able to fetch the phone state. My problem is when the TelephonyManager is equal to CALL_STATE_OFFHOOK i need to pause the MyService and when the TelephonyManager is equal to CALL_STATE_IDLE i need to resume the MyService
you need to use onCallStateChanged method.
put this lines in your onCreate() method,it will initialize object of TelephonyManager and will setup listener for you.
TelephonyManager tManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
ListenToPhoneState listener = new ListenToPhoneState()
tManager.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
class definition of innerclass ListenToPhoneState will be looking like this,
private class ListenToPhoneState extends PhoneStateListener {
boolean callEnded=false;
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
UTILS.Log_e("State changed: " , state+"Idle");
if(callEnded)
{
//you will be here at **STEP 4**
//you should stop service again over here
}
else
{
//you will be here at **STEP 1**
//stop your service over here,
//i.e. stopService (new Intent(`your_context`,`CallService.class`));
//NOTE: `your_context` with appropriate context and `CallService.class` with appropriate class name of your service which you want to stop.
}
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
UTILS.Log_e("State changed: " , state+"Offhook");
//you will be here at **STEP 3**
// you will be here when you cut call
callEnded=true;
break;
case TelephonyManager.CALL_STATE_RINGING:
UTILS.Log_e("State changed: " , state+"Ringing");
//you will be here at **STEP 2**
break;
default:
break;
}
}
}
Explaination: While the call,your listener will go through following states,
Step 1: TelephonyManager.CALL_STATE_IDLE
initially your call state will be idle that is why the variable callEnded will have the value false.
Step 2: TelephonyManager.CALL_STATE_RINGING
now you are waiting for the receiver person to receive your call
Step 3: TelephonyManager.CALL_STATE_OFFHOOK
you cut the call
Step 4: TelephonyManager.CALL_STATE_IDLE
idle again
NOTE: If you don't want to know when the call ends and what should be done after ending the call then just remove callEnded variable and stop the service whenever you enter in the block of TelephonyManager.CALL_STATE_IDLE
I hope it will be helpful !!
You cannot pause or resume a service, you can start your service again when call ends. Inside PhoneStateListener's TelephonyManager.CALL_STATE_OFFHOOK constant, start your service again! Using different states of PhoneStateListener as mentioned by #Tijo, you can decide when to start or stop your service.
I have used TelephonyManager.CALL_STATE_OFFHOOK but unfortunately it gets called every time I touch the call button, i.e before the call is actually made.
my code:
public void onReceive(Context context, Intent intent) {
this.context = context;
listener = new CallStateListener();
if(intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")){
Log.e("Aditya", "Broadcast listner");
//Currently no use
}
TelephonyManager tm = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
tm.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);
}
public class CallStateListener extends PhoneStateListener {
int lastState = TelephonyManager.CALL_STATE_IDLE;
#Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
// called when someone is ringing to this phone
Toast.makeText(context,"Pioneer Contacts+ Updated",Toast.LENGTH_LONG).show();
Log.e("Aditya", "ringing");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Toast.makeText(context,"Pioneer Contacts+ Updated",Toast.LENGTH_LONG).show();
Log.e("Aditya", "offhook");
break;
}
}
}
The Log Log.e("Aditya", "offhook"); gets printed before the call gets connected. I want to appear it after the call is disconnected.
when i tryed to start activity when phone stops ringing and it force closes all the time.
so here's my broadcast reciever
public class Incoming extends BroadcastReceiver {
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
MyPhoneStateListener phoneListener=new MyPhoneStateListener();
TelephonyManager telephony = (TelephonyManager)
arg0.getSystemService(Context.TELEPHONY_SERVICE);
phoneListener.context = arg0;
telephony.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);
}
}
And this should start activity
public class MyPhoneStateListener extends PhoneStateListener {
int prevstate;
public void onCallStateChanged(int state,String incomingNumber){
if(prevstate==TelephonyManager.CALL_STATE_OFFHOOK && state == TelephonyManager.CALL_STATE_IDLE){
Log.i("PARm","Here the activity should start");
}
else if(prevstate==TelephonyManager.CALL_STATE_RINGING && state == TelephonyManager.CALL_STATE_IDLE){
Log.i("PARM","Here the activity should start");
}
switch(state){
case TelephonyManager.CALL_STATE_IDLE:
Log.d("DECallNoteActivity.get getContext();BUG", "IDLE");
prevstate = state;
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("DEBUG", "OFFHOOK");
prevstate = state;
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d("DEBUG", "RINGING");
prevstate = state;
break;
}
}
}
i would be pleased if you could tell me how to get context in this case to start Activity or another way how to start it.
Thank you.
The broadcast receiver's context is only valid for the duration of the onReceive call: you can't save it and reuse it later. If you need to start an Activity this way what you will need to so is start a Service from the BroadcastReceiver's onReceive method, and have that service create the phone state listener and launch the required Activity: once it has launched the Activity it can stop itself.
I need a way to get the the status when a outgoing call is answered. However, in the OFFHOOK state I am also using to call for the outgoing call(ACTION_CALL). How can I add the awnsered state without overriding the outgoing call activity?
public class OutgoingBroadcastReceiver extends BroadcastReceiver {
private Intent mIntent;
private String phonenumber = null;
public static boolean wasRinging;
#Override
public void onReceive(Context context, Intent intent) {
mIntent = intent;
MyPhoneStateListener phoneListener = new MyPhoneStateListener(context);
TelephonyManager telephony = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
}
public class MyPhoneStateListener extends PhoneStateListener {
private final Context context;
public MyPhoneStateListener(Context context) {
this.context = context;
}
#Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
wasRinging = true;
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.e("%%%%%%%%%%%%%%%%%%%%%%%%%%%t", "OFFHOOK");
if (UIUDialer.isOutgoingCall() == true) {
//Do my work when outgoing call is detected
}
else if (!wasRinging)
{
Log.e("%%%%%%%%%%%%%%%%%%%%%%%%%%%t", "WASRINGING");
//Do my work when outgoing call is awnsered
}
context.sendBroadcast(new Intent("finish_incoming"));
wasRinging = true;
break;
case TelephonyManager.CALL_STATE_RINGING:
wasRinging = true;
break;
}
}
}
}
There is no public API available for this.
Why don't you just use the boolean wasRinging?
(you'll have to make it static and remove the initialization, though)
This is my BroadcastReceiver
public class PlayAudio extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
tm.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);
}
}
This is my Custom PhoneStateListener Class
public class CustomPhoneStateListener extends PhoneStateListener {
Context context;
public CustomPhoneStateListener(Context context) {
super();
this.context = context;
}
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
Log.d("PHONEA", "IDLE");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("PHONEA", "OFFHOOK");
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d("PHONEA", "RINGING");
Intent intent = new Intent(this.context, AudioService.class);
context.startService(intent);
break;
default:
break;
}
}
}
and this is my service
public class AudioService extends Service{
private static final String TAG = "PHONEA";
MediaPlayer player;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
Log.d(TAG, "onCreate -> TODO");
}
}
My question is that every time I receive data in Broadcast receiver I create a new instance of the TelephonyManager. So when I view the logcat the first time I get "RINGING", the second time "RINGING" "RINGING" and so on. When should I create my telephonylistener in order to have only one instance?
Regards,
Nicos
You are getting call on your receiver(Asssuming you are listening for PhoneState) every time the phone state change.
You should put some check in your receiver and instatiate the TelephonyManager for the first time only.
