how to detect phone call broadcast receiver in android

how to detect phone call broadcast receiver in android - android

I am building an application in android, which will perform an action when any phone call will come in my phone. I have tried this with broadcast receiver and phone state listener. But it is not working. If i use activity then phone state listener works well and good but it is not working with Broadcast receiver. What i am doing wrong? Please any body help....
Thanks & Regards

Here is an example from a Chinese BBS.
public class PhoneStatReceiver extends BroadcastReceiver{
private static final String TAG = "PhoneStatReceiver";
private static boolean incomingFlag = false;
private static String incoming_number = null;
#Override
public void onReceive(Context context, Intent intent) {
//如果是拨打电话
if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
incomingFlag = false;
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "call OUT:"+phoneNumber);
}else{
//如果是来电
TelephonyManager tm =
(TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
switch (tm.getCallState()) {
case TelephonyManager.CALL_STATE_RINGING:
incomingFlag = true;//标识当前是来电
incoming_number = intent.getStringExtra("incoming_number");
Log.i(TAG, "RINGING :"+ incoming_number);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if(incomingFlag){
Log.i(TAG, "incoming ACCEPT :"+ incoming_number);
}
break;
case TelephonyManager.CALL_STATE_IDLE:
if(incomingFlag){
Log.i(TAG, "incoming IDLE");
}
break;
}
}
}
}
Register it in your AndroidManifest.xml.
<receiver android:name=".filter.PhoneStatReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>

You can find some base code for that in this posts:

How to block calls in android

<receiver android:name="ClassName">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE">/action>
</intent-filter>
</receiver>
Its working!!

I have read here
https://gist.github.com/ftvs/e61ccb039f511eb288ee
It works fine for me. Android version 5.0.
My task had consisted next.
My application must observer all calls events. And distinguish incoming, outgoing calls. Any time when the incoming call has finished it must create the new outgoing call. Phone number specified in settings number. This phone number is the number of gate controller. (https://www.pal-es.com/3g-eng)
It is cheating for opening automatic gates for users, not in the whitelist. This application works into a standalone smartphone and is used decided for this task only.
And some features you can find here too.
For example:
how update textView value from Runnable thread
I make outgoing
call not from BroadcastReceiver class, because it impossible. It
need make from MainActivity. Havy fun))) Try it.

I experienced the same thing initially but then i add the following permission to my manifest.
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
of-course in my code i was just displaying a toast when i got a call.
So, you'll probably have to add other permissions corresponding to your requirement.

onReceive method doesn't get called on the first launch of application

I am trying to perform some implementation against the phone call. by following this link. Everything works fine except the onReceive method from PhonecallReceiver doesn't get called on the first launch of the application, afterward, it works fine. Thanks for your time and help.
PhonecallReceiver
public class PhonecallReceiver extends BroadcastReceiver {
//The receiver will be recreated whenever android feels like it. We need a static variable to remember data between instantiations
private static int lastState = TelephonyManager.CALL_STATE_IDLE;
private static Date callStartTime;
private static boolean isIncoming;

#Override
public void onReceive(Context context, Intent intent) {
//We listen to two intents. The new outgoing call only tells us of an outgoing call. We use it to get the number.
String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
int state = 0;
if(stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)){
state = TelephonyManager.CALL_STATE_IDLE;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
state = TelephonyManager.CALL_STATE_OFFHOOK;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING)){
state = TelephonyManager.CALL_STATE_RINGING;
}
onCallStateChanged(context, state, number);
}
//Derived classes should override these to respond to specific events of interest
protected void onIncomingCallReceived(Context ctx, String number, Date start){}
public void onCallStateChanged(Context context, int state, String number) {
if(lastState == state){
//No change, debounce extras
return;
}
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
isIncoming = true;
callStartTime = new Date();
savedNumber = number;
onIncomingCallReceived(context, number, callStartTime);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
//Transition of ringing->offhook are pickups of incoming calls. Nothing done on them
break;
case TelephonyManager.CALL_STATE_IDLE:
//Went to idle- this is the end of a call. What type depends on previous state(s)

My English expression may not be very good, I hope you can understand
You can make it as `
PhoneStateReceiver phoneStateReceiver = new PhoneStateReceiver();
IntentFilter intentFilter = new IntentFilter();
for (String action : actions) {
intentFilter.addAction(action);
}
c.registerReceiver(phoneStateReceiver,intentFilter);
`
but not register as static,It well be work?
Or
If your application implement InCallService.
Use call.registerCallback(Call.Callback),the Callback worked No abnormality

Required permissions(READ_PHONE_STATE, CALL_PHONE) were being asked separately in the activity(not a better way)
if (Build.VERSION.SDK_INT >= 23) {
if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_PHONE_STATE},
//MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
11);
}
if (getApplicationContext().checkSelfPermission(Manifest.permission.CALL_PHONE)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CALL_PHONE},
//MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
12);
}
}
And as the request for these permissions is asked collectively then the receiver started to invoke on the first launch of the application
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {
Manifest.permission.CALL_PHONE,
Manifest.permission.READ_PHONE_STATE,
};
private void checkPermissions(){
if (!hasPermissions(this, PERMISSIONS)) {
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
}
public static boolean hasPermissions(Context context, String... permissions) {
if (context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;

Broadcast receiver not working in android oreo

My Broadcast receiver is not working on oreo but its working below oreo it's working fine, I searched a lot regarding this but could not find the suitable solution. Does anyone face the same problem, here is my code regarding my service in which broadcast has been implemented. Kindly suggests me that how I can make in working in oreo.

Noting is in coming inside receiever,Can anyone help me out in this?
New Additions as per discussion
Manifest data :-
Permission used :-
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Reciver:-
<receiver android:name="com.example.dialer.AppUtils.StartUpBootReceiver" android:enabled="true" android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />

#Override
public void onReceive(Context context, Intent intent) {
mContext= context;
String action = "START";
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
context.startForegroundService(new Intent(context, PhoneStateService.class));
}
else
{
context.startService(new Intent(context, PhoneStateService.class));
}
}
}
private boolean isServiceRunning(Class<?> serviceClass) {
ActivityManager manager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
if (serviceClass.getName().equals(service.service.getClassName())) {
return true;
}
}
return false;
}
}
Rest the same service will get the call, but the problem is i still does not get call in receiver.And m primary point is that service should only get called once user tap on button , not automatically as i have to pass some values in the service.
Thanks

Broadcast Limitations
If an app registers to receive broadcasts, the app's receiver consumes resources every time the broadcast is sent. This can cause problems if too many apps register to receive broadcasts based on system events; a system event that triggers a broadcast can cause all of those apps to consume resources in rapid succession, impairing the user experience. To mitigate this problem, Android 7.0 (API level 25) placed limitations on broadcasts, as described in Background Optimization. Android 8.0 (API level 26) makes these limitations more stringent.
Apps that target Android 8.0 or higher can no longer register broadcast receivers for implicit broadcasts in their manifest. An implicit broadcast is a broadcast that does not target that app specifically. For example, ACTION_PACKAGE_REPLACED is an implicit broadcast, since it is sent to all registered listeners, letting them know that some package on the device was replaced. However, ACTION_MY_PACKAGE_REPLACED is not an implicit broadcast, since it is sent only to the app whose package was replaced, no matter how many other apps have registered listeners for that broadcast.
Apps can continue to register for explicit broadcasts in their manifests.
Apps can use Context.registerReceiver() at runtime to register a receiver for any broadcast, whether implicit or explicit.
Broadcasts that require a signature permission are exempted from this restriction, since these broadcasts are only sent to apps that are signed with the same certificate, not to all the apps on the device.
From the Official Documentation

The problem comes with the service you're trying to run, services or persistent background services are not permitted to run for long for apps targeting Oreo and above.
Check this guide and this as well for migrating your app to support Oreo.

I also had this kind of issue, but I found a better solution:
Class MyReceiver
#BroadcastReceiverActions({
"android.intent.action.SCREEN_ON",
"android.intent.action.SCREEN_OFF",
"android.intent.action.DREAMING_STARTED",
"android.intent.action.DREAMING_STOPPED",
"android.intent.action.ACTION_POWER_DISCONNECTED",
"android.intent.action.ACTION_POWER_CONNECTED",
"android.net.conn.CONNECTIVITY_CHANGE"
})
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
super();
}
#Override
public void onReceive(Context context, Intent intent) {
Session.getGlobalReceiverCallBack(context, intent);
//Log.e("dfd", "" + intent.getAction());
}
}
Class AppController
public class AppController extends Application {
private BroadcastReceiver receiver;
MyReceiver mR;
#Override
public void onCreate() {
super.onCreate();
mR = new MyReceiver();
receiver = DynamicReceiver.with(mR)
.register(this);
}
}
Class MainActivity
public class MainActivity extends AppCompatActivity implements GlobalReceiverCallBack {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Session.setmGlobalReceiverCallback(this);
}
#Override
public void onCallBackReceived(Context context, Intent intent) {
Toast.makeText(context, "" + intent.getAction(), Toast.LENGTH_LONG).show();
}
}
For complete reference you can see also https://github.com/devggaurav/BroadcastReceiver-For-Naught-and-Oreo-devices

Register your broadcast receiver in activity on create method rather than in manifest and unregister it on destroy method. Hope this will work on android 9.

Android 8.0 offers several improvements to JobScheduler that make it easier to replace services and broadcast receivers with scheduled jobs:
https://developer.android.com/about/versions/oreo/background
In many cases, apps that previously registered for an implicit broadcast can get similar functionality by using a JobScheduler job. For example, a social photo app might need to perform cleanup on its data from time to time, and prefer to do this when the device is connected to a charger. Previously, the app registered a receiver for ACTION_POWER_CONNECTED in its manifest; when the app received that broadcast, it would check whether cleanup was necessary. To migrate to Android 8.0 or higher, the app removes that receiver from its manifest. Instead, the app schedules a cleanup job that runs when the device is idle and charging.

I have faced the similar issue when implementing call recording app,
I have added the following code in the AndroidManifest.xml file, then the register is working normally
<receiver android:name=".Services.Receiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
<action android:name="android.intent.action.ANSWER"/>
<action android:name="android.intent.action.CALL_BUTTON"/>
<action android:name= "android.intent.action.NEW_OUTGOING_CALL"/>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

All broadcasts registered for incoming calls [duplicate]

I'm trying to make an app like, when a call comes to the phone I want to detect the number. Below is what I tried, but it's not detecting incoming calls.
I want to run my MainActivity in background, how can I do that?
I had given the permission in manifest file.
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Is there anything else should I provide in the manifest?
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);
}
public class myPhoneStateChangeListener extends PhoneStateListener {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
if (state == TelephonyManager.CALL_STATE_RINGING) {
String phoneNumber = incomingNumber;
}
}
}
}

Here's what I use to do this:
Manifest:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
My base reusable call detector
package com.gabesechan.android.reusable.receivers;
import java.util.Date;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
public abstract class PhonecallReceiver extends BroadcastReceiver {
//The receiver will be recreated whenever android feels like it. We need a static variable to remember data between instantiations
private static int lastState = TelephonyManager.CALL_STATE_IDLE;
private static Date callStartTime;

}
else{
onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());
}
break;
}
lastState = state;
}
}
Then to use it, simply derive a class from it and implement a few easy functions, whichever call types you care about:
public class CallReceiver extends PhonecallReceiver {
#Override
protected void onIncomingCallReceived(Context ctx, String number, Date start)
{
//
}
#Override
protected void onIncomingCallAnswered(Context ctx, String number, Date start)
{
//
}
#Override
protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
#Override
protected void onOutgoingCallStarted(Context ctx, String number, Date start)
{
//
}
#Override
protected void onOutgoingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
#Override
protected void onMissedCall(Context ctx, String number, Date start)
{
//
}
}
In addition you can see a writeup I did on why the code is like it is on my blog. Gist link: https://gist.github.com/ftvs/e61ccb039f511eb288ee
EDIT: Updated to simpler code, as I've reworked the class for my own use

private MyPhoneStateListener phoneStateListener = new MyPhoneStateListener();
to register
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
and to unregister
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);

With Android P - Api Level 28:
You need to get READ_CALL_LOG permission
Restricted access to call logs
Android P moves the CALL_LOG, READ_CALL_LOG, WRITE_CALL_LOG, and PROCESS_OUTGOING_CALLS permissions from the PHONE permission group to the new CALL_LOG permission group. This group gives users better control and visibility to apps that need access to sensitive information about phone calls, such as reading phone call records and identifying phone numbers.
To read numbers from the PHONE_STATE intent action, you need both the READ_CALL_LOG permission and the READ_PHONE_STATE permission.
To read numbers from onCallStateChanged(), you now need the READ_CALL_LOG permission only. You no longer need the READ_PHONE_STATE permission.

UPDATE: The really awesome code posted by Gabe Sechan no longer works unless you explicitly request the user to grant the necessary permissions. Here is some code that you can place in your main activity to request these permissions:
if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS},
MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
}
ALSO: As someone mentioned in a comment below Gabe's post, you have to add a little snippet of code, android:enabled="true, to the receiver in order to detect incoming calls when the app is not currently running in the foreground:
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>

Just to update Gabe Sechan's answer. If your manifest asks for permissions to READ_CALL_LOG and READ_PHONE_STATE, onReceive will called TWICE. One of which has EXTRA_INCOMING_NUMBER in it and the other doesn't. You have to test which has it and it can occur in any order.
https://developer.android.com/reference/android/telephony/TelephonyManager.html#ACTION_PHONE_STATE_CHANGED

this may helps you and also add require permision
public class PhoneListener extends PhoneStateListener
{
private Context context;
public static String getincomno;
public PhoneListener(Context c) {
Log.i("CallRecorder", "PhoneListener constructor");
context = c;
}
public void onCallStateChanged (int state, String incomingNumber)
{
if(!TextUtils.isEmpty(incomingNumber)){
// here for Outgoing number make null to get incoming number
CallBroadcastReceiver.numberToCall = null;
getincomno = incomingNumber;
}
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d("CallRecorder", "CALL_STATE_RINGING");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
}
}
}

Here is a simple method which can avoid the use of PhonestateListener and other complications.
So here we are receiving the 3 events from android such as RINGING,OFFHOOK and IDLE. And in order to get the all possible state of call,we need to define our own states like RINGING, OFFHOOK, IDLE, FIRST_CALL_RINGING, SECOND_CALL_RINGING.
It can handle every states in a phone call.
Please think in a way that we are receiving events from android and we will define our on call states. See the code.
public class CallListening extends BroadcastReceiver {
private static final String TAG ="broadcast_intent";
public static String incoming_number;
private String current_state,previus_state,event;
public static Boolean dialog= false;

public void onReceive(Context context, Intent intent) {
//Log.d("intent_log", "Intent" + intent);
dialog=true;
this.context = context;
event = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
incoming_number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.d(TAG, "The received event : "+event+", incoming_number : " + incoming_number);
previus_state = getCallState(context);
current_state = "IDLE";
if(incoming_number!=null){
updateIncomingNumber(incoming_number,context);
}else {
incoming_number=getIncomingNumber(context);
}
switch (event) {
case "RINGING":
Log.d(TAG, "State : Ringing, incoming_number : " + incoming_number);
if((previus_state.equals("IDLE")) || (previus_state.equals("FIRST_CALL_RINGING"))){
current_state ="FIRST_CALL_RINGING";
}
if((previus_state.equals("OFFHOOK"))||(previus_state.equals("SECOND_CALL_RINGING"))){
current_state = "SECOND_CALL_RINGING";
}
break;
case "OFFHOOK":
Log.d(TAG, "State : offhook, incoming_number : " + incoming_number);
if((previus_state.equals("IDLE")) ||(previus_state.equals("FIRST_CALL_RINGING")) || previus_state.equals("OFFHOOK")){
current_state = "OFFHOOK";
}
if(previus_state.equals("SECOND_CALL_RINGING")){
current_state ="OFFHOOK";
startDialog(context);
}
break;
case "IDLE":
Log.d(TAG, "State : idle and incoming_number : " + incoming_number);
if((previus_state.equals("OFFHOOK")) || (previus_state.equals("SECOND_CALL_RINGING")) || (previus_state.equals("IDLE"))){
current_state="IDLE";
}
if(previus_state.equals("FIRST_CALL_RINGING")){
current_state = "IDLE";
startDialog(context);
}
updateIncomingNumber("no_number",context);
Log.d(TAG,"stored incoming number flushed");
break;
}
if(!current_state.equals(previus_state)){
Log.d(TAG, "Updating state from "+previus_state +" to "+current_state);
updateCallState(current_state,context);
}
}
public void startDialog(Context context) {
Log.d(TAG,"Starting Dialog box");
Intent intent1 = new Intent(context, NotifyHangup.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);
}
public void updateCallState(String state,Context context){
sp = PreferenceManager.getDefaultSharedPreferences(context);
spEditor = sp.edit();
spEditor.putString("call_state", state);
spEditor.commit();
Log.d(TAG, "state updated");
}
public void updateIncomingNumber(String inc_num,Context context){
sp = PreferenceManager.getDefaultSharedPreferences(context);
spEditor = sp.edit();
spEditor.putString("inc_num", inc_num);
spEditor.commit();
Log.d(TAG, "incoming number updated");
}
public String getCallState(Context context){
sp1 = PreferenceManager.getDefaultSharedPreferences(context);
String st =sp1.getString("call_state", "IDLE");
Log.d(TAG,"get previous state as :"+st);
return st;
}
public String getIncomingNumber(Context context){
sp1 = PreferenceManager.getDefaultSharedPreferences(context);
String st =sp1.getString("inc_num", "no_num");
Log.d(TAG,"get incoming number as :"+st);
return st;
}
}

I fixed Gabe Sechan answer, I used the following code and it worked properly.
I noticed when a receiver intent has the "incoming_number" key, I can get the phone number. So I filtered incoming intent and used EXTRA_INCOMING_NUMBER and EXTRA_PHONE_NUMBER to get the phone number.
public class ChangeCallStateListener extends BroadcastReceiver {
private static String lastState = TelephonyManager.EXTRA_STATE_IDLE;
private static Date callStartTime;
private static boolean isIncoming;
private static String savedNumber; //because the passed incoming is only valid in ringing
#Override
public void onReceive(Context context, Intent intent) {
Log.d("CallObserver", "CallReceiver is starting ....");
List<String> keyList = new ArrayList<>();
Bundle bundle = intent.getExtras();
if (bundle != null) {
keyList = new ArrayList<>(bundle.keySet());
Log.e("CallObserver", "keys : " + keyList);
}
if (keyList.contains("incoming_number")) {
String phoneState = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String phoneIncomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
String phoneOutgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
String phoneNumber = phoneOutgoingNumber != null ? phoneOutgoingNumber : (phoneIncomingNumber != null ? phoneIncomingNumber : "");
if (phoneState != null && phoneNumber != null) {
if (lastState.equals(phoneState)) {
//No change, debounce extras
return;
}
Log.e("CallObserver", "phoneState = " + phoneState);
if (TelephonyManager.EXTRA_STATE_RINGING.equals(phoneState)) {
isIncoming = true;
callStartTime = new Date();
//
lastState = TelephonyManager.EXTRA_STATE_RINGING;
if (phoneNumber != null) {
savedNumber = phoneNumber;
}
onIncomingCallStarted(context, savedNumber, callStartTime);
} else if (TelephonyManager.EXTRA_STATE_IDLE.equals(phoneState)) {
if (lastState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
//
lastState = TelephonyManager.EXTRA_STATE_IDLE;
onMissedCall(context, savedNumber, callStartTime);
} else {
if (isIncoming) {
//
lastState = TelephonyManager.EXTRA_STATE_IDLE;
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
} else {
//
lastState = TelephonyManager.EXTRA_STATE_IDLE;
Log.d("CallObserver", "onOutgoingCallEnded called !! : ");
onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
} else if (TelephonyManager.EXTRA_STATE_OFFHOOK.equals(phoneState)) {
if (lastState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
isIncoming = true;
} else {
isIncoming = false;
}
callStartTime = new Date();
savedNumber = phoneNumber;
//
lastState = TelephonyManager.EXTRA_STATE_OFFHOOK;
onOutgoingCallStarted(context, savedNumber, callStartTime);
}
}
}
}
protected void onIncomingCallStarted(Context ctx, String number, Date start) {
Log.d("CallObserver", "onIncomingCallStarted : " + " number is : " + number);
}
protected void onOutgoingCallStarted(Context ctx, String number, Date start) {
Log.d("CallObserver", "onOutgoingCallStarted : " + " number is : " + number);
}
protected void onIncomingCallEnded(Context context, String number, Date start, Date end) {
}
protected void onOutgoingCallEnded(Context context , String number, Date start, Date end) {
}
protected void onMissedCall(Context context, String number, Date start) {
}
}
Don't forget to get run time permission.
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

#Gabe Sechan, thanks for your code. It works fine except the onOutgoingCallEnded(). It is never executed. Testing phones are Samsung S5 & Trendy. There are 2 bugs I think.
1: a pair of brackets is missing.
case TelephonyManager.CALL_STATE_IDLE:
// Went to idle- this is the end of a call. What type depends on previous state(s)
if (lastState == TelephonyManager.CALL_STATE_RINGING) {
// Ring but no pickup- a miss
onMissedCall(context, savedNumber, callStartTime);
} else {
// this one is missing
if(isIncoming){
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
} else {
onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
// this one is missing
break;
2: lastState is not updated by the state if it is at the end of the function. It should be replaced to the first line of this function by
public void onCallStateChanged(Context context, int state, String number) {
int lastStateTemp = lastState;
lastState = state;
// todo replace all the "lastState" by lastStateTemp from here.
if (lastStateTemp == state) {
//No change, debounce extras
return;
}
//....
}
Additional I've put lastState and savedNumber into shared preference as you suggested.
Just tested it with above changes. Bug fixed at least on my phones.

Please use the below code. It will help you to get the incoming number with other call details.

while (managedCursor.moveToNext()) {

String callType = managedCursor.getString(type);
String callDate = managedCursor.getString(date);

switch (dircode) {
case CallLog.Calls.OUTGOING_TYPE:

break;
case CallLog.Calls.INCOMING_TYPE:

break;
case CallLog.Calls.MISSED_TYPE:

break;
}
sb.append("\nPhone Number:--- " + phNumber + " \nCall Type:--- "

public boolean onCreateOptionsMenu(Menu menu) {

}
}
and in your manifest request for following permissions:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.READ_LOGS"/>

You need a BroadcastReceiver for ACTION_PHONE_STATE_CHANGED This will call your received whenever the phone-state changes from idle, ringing, offhook so from the previous value and the new value you can detect if this is an incoming/outgoing call.
Required permission would be:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
But if you also want to receive the EXTRA_INCOMING_NUMBER in that broadcast, you'll need another permission: "android.permission.READ_CALL_LOG"
And the code something like this:
val receiver: BroadcastReceiver = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
Log.d(TAG, "onReceive")
}
}
override fun onResume() {
val filter = IntentFilter()
filter.addAction("android.intent.action.PHONE_STATE")
registerReceiver(receiver, filter)
super.onResume()
}
override fun onPause() {
unregisterReceiver(receiver)
super.onPause()
}
and in receiver class, we can get current state by reading intent like this:
intent.extras["state"]
the result of extras could be:
RINGING -> If your phone is ringing
OFFHOOK -> If you are talking with someone (Incoming or Outcoming
call)
IDLE -> if call ended (Incoming or Outcoming call)
With PHONE_STATE broadcast we don't need to use PROCESS_OUTGOING_CALLS permission or deprecated NEW_OUTGOING_CALL action.

Refer to the answer by Gabe Sechan. As mentioned, in the case of an Outgoing call, we have the following state change: IDLE -> OFFHOOK -> IDLE. In Gabe's original answer, savedNumber is only set if the phone state becomes RINGING which won't be true for an Outgoing call. A small fix to to also set savedNumber when the phone state becomes OFFHOOK:
case TelephonyManager.CALL_STATE_OFFHOOK:
if(lastState != TelephonyManager.CALL_STATE_RINGING){
//IDLE to OFFHOOK for example.
isIncoming = false;
callStartTime = new Date();
savedNumber = number;
onOutgoingCallStarted(context, savedNumber, callStartTime);
}
...
This fix allows the dialed number to be passed to Outgoing call methods in the same way that the incoming number is passed to Incoming call or Missed call methods.

Hack Alert :)
If you are just interested in the incoming call event, consider using the AudioManager and listening to focus changes.
Advantage - no permission is required.
Disadvantage - won't work in silent mode... in that case, we will increase the volume of the incoming call to the minimum to still get the Audio focus event.
/**
* Register a callback to [AudioManager] to identify an incoming call.
*/
private fun registerAudioFocusChangeListener(){
val audioManager = getSystemService(Context.AUDIO_SERVICE) as AudioManager
val incomingCallVolume = audioManager.getStreamVolume(AudioManager.STREAM_RING)
if(incomingCallVolume == 0) {
// Hack Alert :)
// The user has muted the phone calls, if we still want to intercept the event,
// we set the volume of the incoming call to Minumum otherwise we will not get
// Audio focus event...
try {
audioManager.adjustVolume(
AudioManager.ADJUST_UNMUTE,
AudioManager.FLAG_ALLOW_RINGER_MODES
)
audioManager.setStreamVolume(
AudioManager.STREAM_RING,
audioManager.getStreamMinVolume(AudioManager.STREAM_RING),
0
);
} catch (e : SecurityException){
// DND (Don't Disturb Mode) is probably ON, we are not allowed to set the volume
// in this scenario, But in this case no incoming call is possible anyway.
}
}
val requestBuilder = AudioFocusRequest.Builder(AudioManager.AUDIOFOCUS_GAIN)
requestBuilder.setOnAudioFocusChangeListener { _ ->
Handler(Looper.getMainLooper()).postDelayed({
val mode = audioManager.mode
if(mode == AudioManager.MODE_RINGTONE || mode == AudioManager.MODE_IN_CALL){
//Ring Ring, do your thing
}
}, 100)
}
audioManager.requestAudioFocus(requestBuilder.build())
}

How to detect incoming calls, in an Android device?

I'm trying to make an app like, when a call comes to the phone I want to detect the number. Below is what I tried, but it's not detecting incoming calls.
I want to run my MainActivity in background, how can I do that?
I had given the permission in manifest file.
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Is there anything else should I provide in the manifest?
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);
}
public class myPhoneStateChangeListener extends PhoneStateListener {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
if (state == TelephonyManager.CALL_STATE_RINGING) {
String phoneNumber = incomingNumber;
}
}
}
}

Here's what I use to do this:
Manifest:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>

Then to use it, simply derive a class from it and implement a few easy functions, whichever call types you care about:
public class CallReceiver extends PhonecallReceiver {
#Override
protected void onIncomingCallReceived(Context ctx, String number, Date start)
{
//
}
#Override
protected void onIncomingCallAnswered(Context ctx, String number, Date start)
{
//
}
#Override
protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
#Override
protected void onOutgoingCallStarted(Context ctx, String number, Date start)
{
//
}
#Override
protected void onOutgoingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
#Override
protected void onMissedCall(Context ctx, String number, Date start)
{
//
}
}
In addition you can see a writeup I did on why the code is like it is on my blog. Gist link: https://gist.github.com/ftvs/e61ccb039f511eb288ee
EDIT: Updated to simpler code, as I've reworked the class for my own use

private MyPhoneStateListener phoneStateListener = new MyPhoneStateListener();
to register
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
and to unregister
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);

With Android P - Api Level 28:
You need to get READ_CALL_LOG permission
Restricted access to call logs
Android P moves the CALL_LOG, READ_CALL_LOG, WRITE_CALL_LOG, and PROCESS_OUTGOING_CALLS permissions from the PHONE permission group to the new CALL_LOG permission group. This group gives users better control and visibility to apps that need access to sensitive information about phone calls, such as reading phone call records and identifying phone numbers.
To read numbers from the PHONE_STATE intent action, you need both the READ_CALL_LOG permission and the READ_PHONE_STATE permission.
To read numbers from onCallStateChanged(), you now need the READ_CALL_LOG permission only. You no longer need the READ_PHONE_STATE permission.

UPDATE: The really awesome code posted by Gabe Sechan no longer works unless you explicitly request the user to grant the necessary permissions. Here is some code that you can place in your main activity to request these permissions:
if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS},
MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
}
ALSO: As someone mentioned in a comment below Gabe's post, you have to add a little snippet of code, android:enabled="true, to the receiver in order to detect incoming calls when the app is not currently running in the foreground:
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>

Just to update Gabe Sechan's answer. If your manifest asks for permissions to READ_CALL_LOG and READ_PHONE_STATE, onReceive will called TWICE. One of which has EXTRA_INCOMING_NUMBER in it and the other doesn't. You have to test which has it and it can occur in any order.
https://developer.android.com/reference/android/telephony/TelephonyManager.html#ACTION_PHONE_STATE_CHANGED

this may helps you and also add require permision
public class PhoneListener extends PhoneStateListener
{
private Context context;
public static String getincomno;
public PhoneListener(Context c) {
Log.i("CallRecorder", "PhoneListener constructor");
context = c;
}
public void onCallStateChanged (int state, String incomingNumber)
{
if(!TextUtils.isEmpty(incomingNumber)){
// here for Outgoing number make null to get incoming number
CallBroadcastReceiver.numberToCall = null;
getincomno = incomingNumber;
}
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d("CallRecorder", "CALL_STATE_RINGING");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
}
}
}

Here is a simple method which can avoid the use of PhonestateListener and other complications.
So here we are receiving the 3 events from android such as RINGING,OFFHOOK and IDLE. And in order to get the all possible state of call,we need to define our own states like RINGING, OFFHOOK, IDLE, FIRST_CALL_RINGING, SECOND_CALL_RINGING.
It can handle every states in a phone call.
Please think in a way that we are receiving events from android and we will define our on call states. See the code.
public class CallListening extends BroadcastReceiver {
private static final String TAG ="broadcast_intent";
public static String incoming_number;
private String current_state,previus_state,event;
public static Boolean dialog= false;
private Context context;
private SharedPreferences sp,sp1;
private SharedPreferences.Editor spEditor,spEditor1;
public void onReceive(Context context, Intent intent) {
//Log.d("intent_log", "Intent" + intent);
dialog=true;
this.context = context;
event = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
incoming_number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.d(TAG, "The received event : "+event+", incoming_number : " + incoming_number);
previus_state = getCallState(context);
current_state = "IDLE";
if(incoming_number!=null){
updateIncomingNumber(incoming_number,context);
}else {
incoming_number=getIncomingNumber(context);
}
switch (event) {
case "RINGING":
Log.d(TAG, "State : Ringing, incoming_number : " + incoming_number);
if((previus_state.equals("IDLE")) || (previus_state.equals("FIRST_CALL_RINGING"))){
current_state ="FIRST_CALL_RINGING";
}
if((previus_state.equals("OFFHOOK"))||(previus_state.equals("SECOND_CALL_RINGING"))){
current_state = "SECOND_CALL_RINGING";
}
break;
case "OFFHOOK":
Log.d(TAG, "State : offhook, incoming_number : " + incoming_number);
if((previus_state.equals("IDLE")) ||(previus_state.equals("FIRST_CALL_RINGING")) || previus_state.equals("OFFHOOK")){
current_state = "OFFHOOK";
}
if(previus_state.equals("SECOND_CALL_RINGING")){
current_state ="OFFHOOK";
startDialog(context);
}
break;
case "IDLE":
Log.d(TAG, "State : idle and incoming_number : " + incoming_number);
if((previus_state.equals("OFFHOOK")) || (previus_state.equals("SECOND_CALL_RINGING")) || (previus_state.equals("IDLE"))){
current_state="IDLE";
}
if(previus_state.equals("FIRST_CALL_RINGING")){
current_state = "IDLE";
startDialog(context);
}
updateIncomingNumber("no_number",context);
Log.d(TAG,"stored incoming number flushed");
break;
}
if(!current_state.equals(previus_state)){
Log.d(TAG, "Updating state from "+previus_state +" to "+current_state);
updateCallState(current_state,context);
}
}
public void startDialog(Context context) {
Log.d(TAG,"Starting Dialog box");
Intent intent1 = new Intent(context, NotifyHangup.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);
}
public void updateCallState(String state,Context context){
sp = PreferenceManager.getDefaultSharedPreferences(context);
spEditor = sp.edit();
spEditor.putString("call_state", state);
spEditor.commit();
Log.d(TAG, "state updated");
}
public void updateIncomingNumber(String inc_num,Context context){
sp = PreferenceManager.getDefaultSharedPreferences(context);
spEditor = sp.edit();
spEditor.putString("inc_num", inc_num);
spEditor.commit();
Log.d(TAG, "incoming number updated");
}
public String getCallState(Context context){
sp1 = PreferenceManager.getDefaultSharedPreferences(context);
String st =sp1.getString("call_state", "IDLE");
Log.d(TAG,"get previous state as :"+st);
return st;
}
public String getIncomingNumber(Context context){
sp1 = PreferenceManager.getDefaultSharedPreferences(context);
String st =sp1.getString("inc_num", "no_num");
Log.d(TAG,"get incoming number as :"+st);
return st;
}
}

I fixed Gabe Sechan answer, I used the following code and it worked properly.
I noticed when a receiver intent has the "incoming_number" key, I can get the phone number. So I filtered incoming intent and used EXTRA_INCOMING_NUMBER and EXTRA_PHONE_NUMBER to get the phone number.
public class ChangeCallStateListener extends BroadcastReceiver {
private static String lastState = TelephonyManager.EXTRA_STATE_IDLE;
private static Date callStartTime;
private static boolean isIncoming;
private static String savedNumber; //because the passed incoming is only valid in ringing
#Override
public void onReceive(Context context, Intent intent) {
Log.d("CallObserver", "CallReceiver is starting ....");
List<String> keyList = new ArrayList<>();
Bundle bundle = intent.getExtras();
if (bundle != null) {
keyList = new ArrayList<>(bundle.keySet());
Log.e("CallObserver", "keys : " + keyList);
}
if (keyList.contains("incoming_number")) {
String phoneState = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String phoneIncomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
String phoneOutgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
String phoneNumber = phoneOutgoingNumber != null ? phoneOutgoingNumber : (phoneIncomingNumber != null ? phoneIncomingNumber : "");
if (phoneState != null && phoneNumber != null) {
if (lastState.equals(phoneState)) {
//No change, debounce extras
return;
}
Log.e("CallObserver", "phoneState = " + phoneState);
if (TelephonyManager.EXTRA_STATE_RINGING.equals(phoneState)) {
isIncoming = true;
callStartTime = new Date();
//
lastState = TelephonyManager.EXTRA_STATE_RINGING;
if (phoneNumber != null) {
savedNumber = phoneNumber;
}
onIncomingCallStarted(context, savedNumber, callStartTime);
} else if (TelephonyManager.EXTRA_STATE_IDLE.equals(phoneState)) {
if (lastState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
//
lastState = TelephonyManager.EXTRA_STATE_IDLE;
onMissedCall(context, savedNumber, callStartTime);
} else {
if (isIncoming) {
//
lastState = TelephonyManager.EXTRA_STATE_IDLE;
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
} else {
//
lastState = TelephonyManager.EXTRA_STATE_IDLE;
Log.d("CallObserver", "onOutgoingCallEnded called !! : ");
onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
} else if (TelephonyManager.EXTRA_STATE_OFFHOOK.equals(phoneState)) {
if (lastState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
isIncoming = true;
} else {
isIncoming = false;
}
callStartTime = new Date();
savedNumber = phoneNumber;
//
lastState = TelephonyManager.EXTRA_STATE_OFFHOOK;
onOutgoingCallStarted(context, savedNumber, callStartTime);
}
}
}
}
protected void onIncomingCallStarted(Context ctx, String number, Date start) {
Log.d("CallObserver", "onIncomingCallStarted : " + " number is : " + number);
}
protected void onOutgoingCallStarted(Context ctx, String number, Date start) {
Log.d("CallObserver", "onOutgoingCallStarted : " + " number is : " + number);
}
protected void onIncomingCallEnded(Context context, String number, Date start, Date end) {
}
protected void onOutgoingCallEnded(Context context , String number, Date start, Date end) {
}
protected void onMissedCall(Context context, String number, Date start) {
}
}
Don't forget to get run time permission.
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

#Gabe Sechan, thanks for your code. It works fine except the onOutgoingCallEnded(). It is never executed. Testing phones are Samsung S5 & Trendy. There are 2 bugs I think.
1: a pair of brackets is missing.
case TelephonyManager.CALL_STATE_IDLE:
// Went to idle- this is the end of a call. What type depends on previous state(s)
if (lastState == TelephonyManager.CALL_STATE_RINGING) {
// Ring but no pickup- a miss
onMissedCall(context, savedNumber, callStartTime);
} else {
// this one is missing
if(isIncoming){
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
} else {
onOutgoingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
// this one is missing
break;
2: lastState is not updated by the state if it is at the end of the function. It should be replaced to the first line of this function by
public void onCallStateChanged(Context context, int state, String number) {
int lastStateTemp = lastState;
lastState = state;
// todo replace all the "lastState" by lastStateTemp from here.
if (lastStateTemp == state) {
//No change, debounce extras
return;
}
//....
}
Additional I've put lastState and savedNumber into shared preference as you suggested.
Just tested it with above changes. Bug fixed at least on my phones.

Please use the below code. It will help you to get the incoming number with other call details.

switch (dircode) {

break;
case CallLog.Calls.INCOMING_TYPE:

break;
case CallLog.Calls.MISSED_TYPE:

}
}
and in your manifest request for following permissions:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.READ_LOGS"/>

You need a BroadcastReceiver for ACTION_PHONE_STATE_CHANGED This will call your received whenever the phone-state changes from idle, ringing, offhook so from the previous value and the new value you can detect if this is an incoming/outgoing call.
Required permission would be:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
But if you also want to receive the EXTRA_INCOMING_NUMBER in that broadcast, you'll need another permission: "android.permission.READ_CALL_LOG"
And the code something like this:
val receiver: BroadcastReceiver = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
Log.d(TAG, "onReceive")
}
}
override fun onResume() {
val filter = IntentFilter()
filter.addAction("android.intent.action.PHONE_STATE")
registerReceiver(receiver, filter)
super.onResume()
}
override fun onPause() {
unregisterReceiver(receiver)
super.onPause()
}
and in receiver class, we can get current state by reading intent like this:
intent.extras["state"]
the result of extras could be:
RINGING -> If your phone is ringing
OFFHOOK -> If you are talking with someone (Incoming or Outcoming
call)
IDLE -> if call ended (Incoming or Outcoming call)
With PHONE_STATE broadcast we don't need to use PROCESS_OUTGOING_CALLS permission or deprecated NEW_OUTGOING_CALL action.

Refer to the answer by Gabe Sechan. As mentioned, in the case of an Outgoing call, we have the following state change: IDLE -> OFFHOOK -> IDLE. In Gabe's original answer, savedNumber is only set if the phone state becomes RINGING which won't be true for an Outgoing call. A small fix to to also set savedNumber when the phone state becomes OFFHOOK:
case TelephonyManager.CALL_STATE_OFFHOOK:
if(lastState != TelephonyManager.CALL_STATE_RINGING){
//IDLE to OFFHOOK for example.
isIncoming = false;
callStartTime = new Date();
savedNumber = number;
onOutgoingCallStarted(context, savedNumber, callStartTime);
}
...
This fix allows the dialed number to be passed to Outgoing call methods in the same way that the incoming number is passed to Incoming call or Missed call methods.

Hack Alert :)
If you are just interested in the incoming call event, consider using the AudioManager and listening to focus changes.
Advantage - no permission is required.
Disadvantage - won't work in silent mode... in that case, we will increase the volume of the incoming call to the minimum to still get the Audio focus event.
/**
* Register a callback to [AudioManager] to identify an incoming call.
*/
private fun registerAudioFocusChangeListener(){
val audioManager = getSystemService(Context.AUDIO_SERVICE) as AudioManager
val incomingCallVolume = audioManager.getStreamVolume(AudioManager.STREAM_RING)
if(incomingCallVolume == 0) {
// Hack Alert :)
// The user has muted the phone calls, if we still want to intercept the event,
// we set the volume of the incoming call to Minumum otherwise we will not get
// Audio focus event...
try {
audioManager.adjustVolume(
AudioManager.ADJUST_UNMUTE,
AudioManager.FLAG_ALLOW_RINGER_MODES
)
audioManager.setStreamVolume(
AudioManager.STREAM_RING,
audioManager.getStreamMinVolume(AudioManager.STREAM_RING),
0
);
} catch (e : SecurityException){
// DND (Don't Disturb Mode) is probably ON, we are not allowed to set the volume
// in this scenario, But in this case no incoming call is possible anyway.
}
}
val requestBuilder = AudioFocusRequest.Builder(AudioManager.AUDIOFOCUS_GAIN)
requestBuilder.setOnAudioFocusChangeListener { _ ->
Handler(Looper.getMainLooper()).postDelayed({
val mode = audioManager.mode
if(mode == AudioManager.MODE_RINGTONE || mode == AudioManager.MODE_IN_CALL){
//Ring Ring, do your thing
}
}, 100)
}
audioManager.requestAudioFocus(requestBuilder.build())
}

NFC Intent Filter - Sending Message Non-Main Activity

I am sure this is simple but I cannot figure it out. All I am trying to do is send a message via NFC. The code I have work perfectly if I am sending it to the main activity, but I don't know how to send it to a different activity. I have looked over both the NFC and Intent Filter articles on the Android Developer pages but am still not sure exactly how to do this. I am trying to send it to a NFC activity, I will post my manifest and NFC class below.
