It is sort of hack, you can use accessibility service to receive call. To enable accessibility service, you must enable your service on Setting - Accessibility - Your service.

First, add typeWindowContentChanged to accessibilityEventTypes.

And do something with event or "displayed text" or "contents description".

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {

    // Do something with Click or Focused event
    final int eventType = event.getEventType();
    String eventText = null;
    switch(eventType) {
        case AccessibilityEvent.TYPE_VIEW_CLICKED:
            eventText = "Focused: ";
            break;
        case AccessibilityEvent.TYPE_VIEW_FOCUSED:
            eventText = "Focused: ";
            break;
    }
    eventText = eventText + event.getContentDescription();


    // Traverse all items in screen. 
    // Do something with text.

    AccessibilityNodeInfo info = getRootInActiveWindow();

    int index;
    int count = info.getChildCount();
    AccessibilityNodeInfo child;

    for (index = 0; index < count; index++) {
        child = info.getChild(index);
        if (child.getText() != null)
            Log.d(TAG, "text: " + child.getText().toString() + " " + child.getContentDescription());

        // perform Click
        //if (child.isClickable());
            //child.performAction(AccessibilityNodeInfo.ACTION_CLICK);
    }
}

Yes, I know this is not a graceful way to solve your problem. It is a kind of hack.
