android – Intent to be fired when a call ends?

Posted by: admin June 15, 2020 Leave a comment


I have an already built application and I want to add a feature that has to be started when a call ends.
How can I achieve that?
I thought that declaring in my manifest something like this

<activity android:name="Filter">
            <category android:name="android.intent.SOMETHING" />

could be enough, but what kind of Intent I have to put on the filter?

Looking in the documentation I found only the intents that detects when a call is started.

Is what I’m looking for possible?

How to&Answers:

You can use the PhoneStateLisenter to listen out for changes in the call state.

So you listen for the LISTEN_CALL_STATE change.

With the onCallStateChanged method.

So when the state changes from OFFHOOK to IDLE start your application


I have done this using a broadcast receiver. Works! code looks like this –


<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <receiver android:name=".IncomingCallTracker">
                <action android:name="android.intent.action.PHONE_STATE" />


The IncomingCallTracker code snippet looks like –

public class IncomingCallTracker extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {

        Bundle bundle = intent.getExtras();

            Set<String> keys = bundle.keySet();
        for (String key : keys) {
                Log.i("MYAPP##", key + "="+ bundle.getString(key));


You can look for the key ‘state’ in the bundle. When its value is ‘IDLE’ it means call has ended and you can perform whatever action you want to based on this.
