How to auto accept calls on android?

Question

Is it possible to Answer the call programmatically and accept DTMF input on phone? Think about it as small hard-coded IVR on mobile device. I tried looking for docs but could find any.

Answer 1

This only really answers part of your question but you will need a BroadcastReceiver that will receive notifications of call state. For example you would have something like following in AndroidManfest.xml and then, in broadcast receiver, check for TelephonyManager.EXTRA_STATE_RINGING state.

    <receiver
        android:name="MyPhoneStateReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
    </receiver>
