How can I detect outgoing call is connected in Android

Question

how I can detect when outgoing call is connected. My code is below but when have incomingcall it get in this if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING))

when there is not activity it get in this

else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE))

when incomingcall is answer it will get in this and outgoingcall it will get in this.

else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK))

and now when outgoingcall it's state is offhook how can i know when my outgoingcall is connected.

Thank you

@Override
public void onReceive(Context context, Intent intent) {
    // TODO: This method is called when the BroadcastReceiver is receiving
    // an Intent broadcast.
    if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)){
        String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        Toast.makeText(context, "Call From : " + incomingNumber, Toast.LENGTH_LONG).show();

    }
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE)){
        Toast.makeText(context,TelephonyManager.EXTRA_STATE_IDLE,Toast.LENGTH_LONG).show();
    }
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
        Toast.makeText(context,TelephonyManager.EXTRA_STATE_OFFHOOK,Toast.LENGTH_LONG).show();
    }
}

Add this in Android Manifest file. Declare Broadcast receiver.

    <receiver
        android:name=".OutCallLogger"
        android:enabled="true"
        android:exported="true" >
            <intent-filter>
                <action android:name="android.intent.action.PRECISE_CALL_STATE" />
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
    </receiver>

Add below permissions in android manifest file.

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.READ_PRECISE_PHONE_STATE" />

Also add this line in manifest file.

<uses-feature android:name="android.hardware.telephony">
</uses-feature>

And this is your class which will be used for getting precised call state for outgoing calls.

public class OutCallLogger extends BroadcastReceiver {
public OutCallLogger() {
}
TelephonyManager Tm;
ITelephony telephonyService;
Class c = null;
Method methodGetInstance = null;
Method methodGetActiveFgCallState=null;
String TAG="Tag";
Object objectCallManager=null;
Context context1;
Class<?> classCallManager;

Class telephonyClass;
Class telephonyStubClass;
Class serviceManagerClass;
Class serviceManagerStubClass;
Class serviceManagerNativeClass;
Class serviceManagerNativeStubClass;

Method telephonyCall;
Method telephonyEndCall;
Method telephonyAnswerCall;
Method getDefault;

Method[] temps;
Constructor[] serviceManagerConstructor;

// Method getService;
Object telephonyObject;
Object serviceManagerObject;
private Timer timer= null;

@Override
public void onReceive(Context context, Intent intent) {
    // TODO: This method is called when the BroadcastReceiver is receiving
    // an Intent broadcast.



    this.context1= context;
    try {
        //String serviceManagerName = "android.os.IServiceManager";
        String serviceManagerName = "android.os.ServiceManager";
        String serviceManagerNativeName = "android.os.ServiceManagerNative";
        String telephonyName = "com.android.internal.telephony.ITelephony";


        telephonyClass = Class.forName(telephonyName);
        telephonyStubClass = telephonyClass.getClasses()[0];
        serviceManagerClass = Class.forName(serviceManagerName);
        serviceManagerNativeClass = Class.forName(serviceManagerNativeName);

        Method getService = // getDefaults[29];
                serviceManagerClass.getMethod("getService", String.class);

        Method tempInterfaceMethod = serviceManagerNativeClass.getMethod(
                "asInterface", IBinder.class);

        Binder tmpBinder = new Binder();
        tmpBinder.attachInterface(null, "fake");

        serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
        IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
        Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
        Method[] aClassMethods = telephonyClass.getDeclaredMethods();
        for(Method m : aClassMethods)
        {
            //Log.e("MEthods", m.getName());
        }
        telephonyObject = serviceMethod.invoke(null, retbinder);
        //telephonyCall = telephonyClass.getMethod("call", String.class);
        telephonyEndCall = telephonyClass.getMethod("getPreciseCallState");
        //telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");
        Log.e("CallState",telephonyEndCall.invoke(telephonyObject).toString());
        Toast.makeText(context1, " "+telephonyEndCall.invoke(telephonyObject).toString(), Toast.LENGTH_LONG).show();

        telephonyEndCall.invoke(telephonyObject);

    } catch (Exception e) {
        e.printStackTrace();

    }

}
