在android中检测传入的视频通话

Question

I want to know how to detect an incoming Video call on android device? Actually there are lots of documentation on detecting incoming phone calls but I couldn't find any information on detecting incoming native video calls in android?
I found source code of Samsung Phone.apk and find this method localConnection.getCall().isVideoCall() or this.mPhone.getForegroundCall().isVideoCall() that detect VideoCall but this method needs import com.android.internal.telephony.* and this is not allowed for third party applications.
I think to call this classes need use reflection.
So may you let me know on this?


and excuse me i cant speak English very well but i think you understand me.

Answer 1

Like @Ankit is saying you can use iTelephony just like in the AutoAnswer code but you have to add a line to this file (that you have to put on your project) :

/**
 * Return TRUE, if current call is video call
 * First active call has priority
 */
boolean isVideoCall();

and then you can use it like this:

private Boolean isVideoCall(Context context) {

    Class<?> c;
    try {
        c = Class.forName(manager.getClass().getName());
        Method m = c.getDeclaredMethod("getITelephony");
        m.setAccessible(true);
        telephonyService = (ITelephony) m.invoke(manager);

    return telephonyService.isVideoCall();
    } catch (Exception e) {
        telephonyService = null;
        e.printStackTrace();
return false;
    }
}

Just detect the incoming call like the code that is on auto-answer and then do this check to see if it is video.

Answer 2

FIrst of all your english is Good, so dont worry.

Yes if you think accessing telephony apis let you do this, then here is an example which uses internal telephony apis directly from user space applicatoin..

Auto_answer app using internalTelephony by reflection

Android does not have a built in system for video calls. Yes, the API's are there to access the cameras, but there's no native app to handle video calls. What video calls do you want to capture? Video calls using Google Hangouts? Skype? Yahoo! Messenger? All these apps allow for video calls, so you need to support those independently if they offer their own API's.
