After a phone call ends, I must open another Activity.
However, it doesn't catch the "call end signal".
I've used mTelManager in BroadcastReceiver and Service, but it doesn't work.
When Activity is opened by a Service or BroadcastReceiver, it shows the MainActivity and not the targeted one instead.
Source code:
public class MainService extends Service{
TelephonyManager mTelManager;
PhoneStateRead pListener;
String TAG = "Call State catch";
boolean callOutState = false; //calling state
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate() {
Log.i(TAG, "ServiceReceiver->onReceive();");
pListener = new PhoneStateRead();
mTelManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
mTelManager.listen(pListener, PhoneStateListener.LISTEN_CALL_STATE);
if(callOutState){ //if call end
Intent showRecord = new Intent(getBaseContext(), Call_Out_Record_Activity.class);
showRecord.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(showRecord);//open Call_Out_Record_Activity
}
}
public class PhoneStateRead extends PhoneStateListener {
private final String TAG = "Phone State Read";
#Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> CALL_STATE_IDLE "+incomingNumber);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> CALL_STATE_OFFHOOK "+incomingNumber);
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> CALL_STATE_RINGING "+incomingNumber);
break;
default:
Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> default -> "+Integer.toString(state));
break;
}
CatchCallState(state);
}
}
private void CatchCallState(int state){
if(state == TelephonyManager.CALL_STATE_OFFHOOK || state == TelephonyManager.CALL_STATE_RINGING)
callOutState = false;
else if(state == TelephonyManager.CALL_STATE_IDLE)
callOutState = true;
}
}
So it looks like you have a couple problems here. First, you are trying to start your activity when you start your Service - you should do this code:
if(callOutState){ //if call end
Intent showRecord = new Intent(getBaseContext(), Call_Out_Record_Activity.class);
showRecord.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(showRecord);//open Call_Out_Record_Activity
}
in the CallStateListener. Or just put it in your CatchCallState method.
Next, notice that there is not a "call end signal" - the phone will go from "OFF_HOOK" to "IDLE" so you need flags to track that. Also, notice that "RINGING" happens on incoming calls, but not outgoing calls. So you may want to display different messages depending on incoming or outgoing calls.

I'm developing an app that will only be used in house for testing purpose. I have searched a lot and tried different suggestions as suggested in different post but none seems to be working for me.
I'm open to any suggestions like Reflections, Accessibility Service, root or any other hack. Please help.

TRY THIS
Set all required permission in manifest.xml file.
Call this class in Service
public class PhoneListener extends PhoneStateListener {
private static PhoneListener instance = null;
/**
* Must be called once on app startup
*
* #param context - application context
* #return
*/
public static PhoneListener getInstance(Context context) {
if (instance == null) {
instance = new PhoneListener(context);
}
return instance;
}
public static boolean hasInstance() {
return null != instance;
}
private final Context context;
private CallLog phoneCall;
private PhoneListener(Context context) {
this.context = context;
}
AtomicBoolean isRecording = new AtomicBoolean();
AtomicBoolean isWhitelisted = new AtomicBoolean();
/**
* Set the outgoing phone number
* <p/>
* Called by {#link MyCallReceiver} since that is where the phone number is available in a outgoing call
*
* #param phoneNumber
*/
public void setOutgoing(String phoneNumber) {
if (null == phoneCall)
phoneCall = new CallLog();
phoneCall.setPhoneNumber(phoneNumber);
phoneCall.setOutgoing();
// called here so as not to miss recording part of the conversation in TelephonyManager.CALL_STATE_OFFHOOK
isWhitelisted.set(Database.isWhitelisted(context, phoneCall.getPhoneNumber()));
}
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE: // Idle... no call
if (isRecording.get()) {
RecordCallService.stopRecording(context);
phoneCall = null;
isRecording.set(false);
}
break;
case TelephonyManager.CALL_STATE_OFFHOOK: // Call answered
if (isWhitelisted.get()) {
isWhitelisted.set(false);
return;
}
if (!isRecording.get()) {
isRecording.set(true);
// start: Probably not ever usefull
if (null == phoneCall)
phoneCall = new CallLog();
if (!incomingNumber.isEmpty()) {
phoneCall.setPhoneNumber(incomingNumber);
}
// end: Probably not ever usefull
RecordCallService.sartRecording(context, phoneCall);
}
break;
case TelephonyManager.CALL_STATE_RINGING: // Phone ringing
// DO NOT try RECORDING here! Leads to VERY poor quality recordings
// I think something is not fully settled with the Incoming phone call when we get CALL_STATE_RINGING
// a "SystemClock.sleep(1000);" in the code will allow the incoming call to stabilize and produce a good recording...(as proof of above)
if (null == phoneCall)
phoneCall = new CallLog();
if (!incomingNumber.isEmpty()) {
phoneCall.setPhoneNumber(incomingNumber);
// called here so as not to miss recording part of the conversation in TelephonyManager.CALL_STATE_OFFHOOK
isWhitelisted.set(Database.isWhitelisted(context, phoneCall.getPhoneNumber()));
}
break;
}
}
}
And use Broadcast Receiver
public class MyCallReceiver extends BroadcastReceiver {
public MyCallReceiver() {
}
static TelephonyManager manager;
#Override
public void onReceive(Context context, Intent intent) {
Log.i("JLCreativeCallRecorder", "MyCallReceiver.onReceive ");
if (!AppPreferences.getInstance(context).isRecordingEnabled()) {
removeListener();
return;
}
if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) {
if (!AppPreferences.getInstance(context).isRecordingOutgoingEnabled()) {
removeListener();
return;
}
PhoneListener.getInstance(context).setOutgoing(intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER));
} else {
if (!AppPreferences.getInstance(context).isRecordingIncomingEnabled()) {
removeListener();
return;
}
}
// Start Listening to the call....
if (null == manager) {
manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
}
if (null != manager)
manager.listen(PhoneListener.getInstance(context), PhoneStateListener.LISTEN_CALL_STATE);
}
private void removeListener() {
if (null != manager) {
if (PhoneListener.hasInstance())
manager.listen(PhoneListener.getInstance(null), PhoneStateListener.LISTEN_NONE);
}
}
}
I hope you get some help from this code.
Thanks
You can use accessibility events to detect the call duration and from that you can detect if the outgoing call is answered or not..
I have answered it in detail in Here` you can check that.
You need this permission in manifest
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
TelephonyManager has a listener to get phone state. implement this tho know if the phone is ringing or in a call.
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
PhoneStateListener callStateListener = new PhoneStateListener() {
public void onCallStateChanged(int state, String incomingNumber) {
// TODO React to a incoming call.
try {
if (state == TelephonyManager.CALL_STATE_RINGING) {
Toast.makeText(getApplicationContext(), "Phone Is Ringing" + incomingNumber, Toast.LENGTH_LONG).show();
number = incomingNumber;
//g.setPhoneNo(incomingNumber);
AndroidNetCommunicationClientActivity.mMsgSendRequest("CommandMsgCallIncoming" + number);
} else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
Toast.makeText(getApplicationContext(), "Phone is Currently in A call" + incomingNumber, Toast.LENGTH_LONG).show();
//number = mIntent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
number = incomingNumber;
} else if (state == TelephonyManager.DATA_DISCONNECTED) {
number = "";
CallID = "";
}
} catch (Exception e) {
// TODO Auto-generated catch block
//conn.MessageBox(MainActivity.this, e.getMessage());
e.printStackTrace();
}
super.onCallStateChanged(state, incomingNumber);
}
};
telephonyManager.listen(callStateListener, PhoneStateListener.LISTEN_CALL_STATE);
I am trying to delete a particular incoming number from call log when phone hang-up. I tried as i can do but that code not working the number still remain in call log.
it is working properly when broadcast invoke but this is not deleting number of incoming call.
Thanks in Advance.
public class ListenPhoneState extends BroadcastReceiver {
private boolean isPressOffHock = false;
static private String incomingNumberToDelete;
#Override
public void onReceive(Context context, Intent intent) {
try {
// TELEPHONY MANAGER class object to register one listner
TelephonyManager tmgr = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
//Create Listner
MyPhoneStateListener PhoneListener = new MyPhoneStateListener();
// Register listener for LISTEN_CALL_STATE
tmgr.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
} catch (Exception e) {
Log.e("Phone Receive Error", " " + e);
}
if(incomingNumberToDelete != null)
{
String queryString="NUMBER="+incomingNumberToDelete;
context.getContentResolver().delete(CallLog.Calls.CONTENT_URI,queryString,null);
Log.d("Delete", "Delete Number " + incomingNumberToDelete );
}
}
private class MyPhoneStateListener extends PhoneStateListener {
public void onCallStateChanged(int state, String incomingNumber) {
if(state == TelephonyManager.CALL_STATE_RINGING)
{
incomingNumberToDelete = incomingNumber;
Log.d("Check", "income " + incomingNumberToDelete );
}
switch(state) {
case TelephonyManager.CALL_STATE_IDLE:
//Log.d("IDLE", state + "incoming" + incomingNumber);
isPressOffHock = true;
break;
case TelephonyManager.CALL_STATE_RINGING:
//Log.d("RINGING", state + "incoming" + incomingNumber);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
String msg = "New Phone Call Event. Incomming Number : "+incomingNumber;
// Log.d("CALL_STATE_OFFHOOK",msg );
break;
}
}
}
}
Usually there is a delay between the broadcast of a phone state and the system data that is written or system activities (such as call logs or phone ringing). Right now, your receiver is probably trying to delete the call log before it is present.
You could delay the delete or take a look at this post for registering a ContentObserver:
Delete call from call log after call end
hello im using a broadcast reciever to try to find out when a call is "made" and after the call is "made" also when the made call is "connected" i searched around and came up with this code but this works when recievng a call and making a call, all i really need is when the call is made and connected, any help in guiding me in this is appreciated, thank you for your time
receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
//action for phone state changed
Toast.makeText(context, "Receiver call status", Toast.LENGTH_SHORT).show();
Log.d("reciever","entered keep going");
if(telephonyManager.getDataState() == TelephonyManager.DATA_CONNECTED){
Toast.makeText(context, "Receiver call connected", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(context, "Receiver call not connected", Toast.LENGTH_SHORT).show();
}
}
}
};
IntentFilter filter = new IntentFilter();
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
registerReceiver(receiver,filter);
Here you can find all states of call, just make handle this states, like i did:
public class PhoneState extends PhoneStateListener {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
//Some Action
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
//Some Action
break;
//case TelephonyManager.ANOTHER_STATE: ...
}
}
}
I want to pause my android application when the phone receives an incoming call. After the call ends, I want my applications to resume automatically.
How would this be implemented in an Android application?
you have to implement a Listener for the PhoneState. I did this in a private Class:
private class PhoneCallListener extends PhoneStateListener {
private boolean isPhoneCalling = false;
// needed for logging
String TAG = "PhoneCallListener";
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if (TelephonyManager.CALL_STATE_RINGING == state) {
// phone ringing
Log.i(TAG, "RINGING, number: " + incomingNumber);
}
if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
// active
Log.i(TAG, "OFFHOOK");
isPhoneCalling = true;
}
if (TelephonyManager.CALL_STATE_IDLE == state) {
// run when class initial and phone call ended,
// need detect flag from CALL_STATE_OFFHOOK
Log.i(TAG, "IDLE");
if (isPhoneCalling) {
Log.i(TAG, "restart app");
// restart call application
Intent i = getBaseContext().getPackageManager()
.getLaunchIntentForPackage(
getBaseContext().getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(i);
isPhoneCalling = false;
}
}
}
}
and you need to add the permission to the Manifest-File
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
private class EndCallListener extends PhoneStateListener {
private boolean active = false;
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if(TelephonyManager.CALL_STATE_RINGING == state) {
Log.i("EndCallListener", "RINGING, number: " + incomingNumber);
}
if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
//wait for phone to go offhook (probably set a boolean flag) so you know your app initiated the call.
active = true;
Log.i("EndCallListener", "OFFHOOK");
}
if(TelephonyManager.CALL_STATE_IDLE == state) {
//when this state occurs, and your flag is set, restart your app
Log.i("EndCallListener", "IDLE");
if (active) {
active = false;
// stop listening
TelephonyManager mTM = (TelephonyManager) m_activity.getSystemService( Context.TELEPHONY_SERVICE );
mTM.listen(this, PhoneStateListener.LISTEN_NONE);
// restart the inbox activity
//Intent intent = new Intent(m_activity, MDInboxActivity.class);
//m_activity.startActivity(intent);
}
}
}
}
And you can initialize the above class by calling the below lines:
try {
EndCallListener callListener = new EndCallListener();
TelephonyManager mTM = (TelephonyManager) m_activity.getSystemService(Context.TELEPHONY_SERVICE);
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
} catch(Exception e) {
Log.e("callMonitor", "Exception: "+e.toString());
}
I am trying to use BroadcastReceiver to receive incoming calls. I want to register call when the call is ended. Below code gives each state (idle,ringing n offhook) more than once with the same number (its not an issue of past call). Is it because phonestatelistner is called within the service.
public class IncomingCallReceiver extends BroadcastReceiver {
int stateString =0;
int prevStat = 0;
#Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
{
String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
String info = "Detect Calls sample application\nIncoming number: " + phonenumber;
Toast.makeText(context, info, Toast.LENGTH_LONG).show();
}
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
//CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener();
PhoneStateListener listener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
String p = incomingNumber;
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
prevStat = stateString;
stateString = 1;
Log.i("ON CALL STATE CHANGED","IDLE");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.i("ON CALL STATE CHANGED","OFFFHOOK");
prevStat = stateString;
stateString = 2;
break;
case TelephonyManager.CALL_STATE_RINGING:
prevStat = stateString;
stateString = 3;
Log.i("ON CALL STATE CHANGED","RINGING");
break;
}
if(prevStat == 2 && stateString == 1)
{
Log.i("REGISTER A CALLL","==" +p);
}
}
};
telephony.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
}
}
I also tried the same thing with phonestatelistener in a separate class, but it was not being called, i.e my code didn't reach there. In my manifest file I have registered receiver, but there is no declaration of phonestatelistener. Is that to be registered?
I am sorry if the solution is quite obvious but am new to android things.
Any help is appreciated :)
Yes, choose listener or received , not both of them
