Detect Missed Call In Android

How to detect a Missed Call in Android

Prerequisite:You should know how to handle Incoming Call. if not, read the post  Handle Incomig Calls using BroadCastReceiver

How to approach :
whenever there as an incoming Phone goes in "RINGING" state, and if the person has not picked/received the call Phone Rings till a particular time and then goes in "IDLE" state.   So we have to monitor the Phone State and check the State accordingly.

Permission Required: 

Following permission is required to listen/monitor the Phone State.
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
Declare the above permission in manifest file.

Listening Phone State:

We use a BroadcastReceiver class that will monitor the Phone State, whenever there is a change in Phone State, the onReceive() method of BroadcasrReceiver will be called, and in onReceivee(),  we check for the condition, See the Code below

do not forget to register the BroadcastReceiver in manifest  (see the manifest file at the bottom )

IncommingCallReceiver.java

public class IncommingCallReceiver extends BroadcastReceiver
 {
   
      static boolean ring=false;
      static boolean callReceived=false;
     
     
      @Override
      public void onReceive(Context mContext, Intent intent)
      {
         
             // Get the current Phone State
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
           
            if(state==null)
                return;

            // If phone state "Rininging"
            if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
            {           
                      ring =true;
                     // Get the Caller's Phone Number
                     Bundle bundle = intent.getExtras();
                     callerPhoneNumber= bundle.getString("incoming_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, "It was A MISSED CALL from : "+callerPhoneNumber, Toast.LENGTH_LONG).show();
                       }
          }
       
}

 Your manifest should look like follows

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.missedcall"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />
   
       <!--  declare the permission -->
        <uses-permission android:name="android.permission.READ_PHONE_STATE" />
   

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
              
        <!-- Register the Broadcast receiver  -->
        <receiver android:name=".IncommingCallReceiver" android:enabled="true">
            <intent-filter>
                    <action android:name="android.intent.action.PHONE_STATE" />
                </intent-filter>
           </receiver>
    </application>

</manifest>
