Welcome back everyone. So it's time to demo the application we made. First, of course, we're gonna deploy it to the board or at least go over a slide that kind of outlines what we did to deploy it to the board. Randy put something good together for you. >> So just in case you need a reminder, because remember we've done this before multiple times in the previous courses, previous lessons, previous modules, etc., everything. So, after you've pulled the code from the repository, you wanna go ahead and load it up in Android Studio. And in Android Studio you have a run button at the top or you can go straight, at the top there's a little play button, or you can go to the drop down menu and click Run. On most systems you can also do Ctrl+R, which is the default key binding to run the app. And then you wanna make sure your device is plugged in. So power it on, make sure you're in developer mode. >> USB debugging has to be activated. >> Yeah, and then plug in your device. Your device should appear on the window and go ahead and deploy it. >> Yeah, so if you need a refresher on this, go back to course two where we set up the whole development environment >> And maybe check out some of the videos again, get familiar with ADB again. You'll be fine, we've done it plenty of times, so you should be familiar with it by now. So that being said, we already actually pushed our application onto our DragonBoard. So we are sitting pretty right now. All right, now we wanna show you a demo, right? >> Yeah, we're gonna go ahead and- >> Yeah, we talked about Linphone earlier in this course. We wanted to show you how our application can actually communicate with other SIP based VoIP application. So Linphone being a SIP based application. We're going to pull up a Linphone app on an iPhone, actually. And then we are going to communicate with the application that we made on the DragonBoard. So let's take a look at the DragonBoard screen here, and then we're gonna actually kind of show you both of these screens so you'll get a chance to see everything that's happening here. So we have the DragonBoard screen. Should have the other phone screen right here, and we're gonna make this call. So I'm gonna open up the application that we made as a VoIP demo. Now what do we have to put up here? >> So, If I remember in the previous lesson, I mentioned for one level security we have the authorization code. So you need to enter that in. >> That's password, right? >> Yeah, don't tell anyone. So password. It'll unlock the app, and you can use it, make the calls and what not. >> And then I'm gonna call you, right? So yours is calit? >> Yeah, it's calit2tester- >> 2? tester 2? And so it already has all of the suffixes. >> Yeah, it automatically appends and puts things like the at siv- >> At siv.linphone and everything in there. So, all right, so now I'm gonna make the call. And we're not gonna answer this call, we're just gonna show you that it's connecting. So real time right here, make call, boom. >> Here we go. >> So he could answer that. You know I have this nifty headset on. He's not gonna answer it, just gonna hit end. But I could talk here or go into the DragonBoard through the Internet all the way to his phone. >> Yeah, so that means you also, communicate with other computers because there's a desktop Linphone version as well. It's pretty neat. >> Yeah, so now what we wanna do is we wanna show you something that's even cooler. We wanna take our application. We put our application on his Android phone. And then we have the exact same application on the DragonBoard. So we're gonna kinda pull up the same thing again. We're gonna take a look at the DragonBoard screen here. >> Okay, so now we're gonna go ahead and demo it on an Android device, so you guys can just pretend it's a DragonBoard, right? >> Yeah, so essentially, this is Android, we're running Android on the DragonBoard. If you had two DragonBoards, you could put this application on both DragonBoards and talk to each other. So what, you already got the authorization set up in there? >> I got the authorization set up and I have the account I'm gonna call, which is on there, so that's MOOC SIP. And you've ended the call that we previously did before, and go ahead and make call and bam. >> All right, so yeah, as you can see, I have the the phone is picking up. That's his calit2_buddy, I can accept this. You're not gonna really hear anything. We're not hooked up that way. But if you did this at home you would be talking to your friend. Or maybe a partner that you're developing DragonBoard 410c stuff with. >> Yeah, sweet. >> Yeah, awesome. Yeah, we're all set. So what we do wanna go over with, we wanna go back to the slide show. We wanna talk to you about some stuff that you could add into this application that we gave. >> Yeah, remember I mentioned multiple times, this app's pretty bare bones. You can just call somebody or receive calls from someone else. The security level is pretty weak, because a lot of things are hard-coded in and you just have one simple password request. So here on the slides, you guys can just check it out, pause video, or load up the slides yourselves. And maybe there's some suggestions for ways to improve the app. Make it better, make more of a buzz, make it cooler, make it more like Linphone maybe or like improved version Linphone, improved version- >> Yeah, we went over this in a previous lesson, in this particular module in fact, where we talked about Linphone. All the cool features they have in there, it's open source. They have open source Android. So, you can go in there, take out a bunch of features, throw them in this application, create new classes, do all sorts of cool stuff. Make your version of this application more robust. We'd love to see it on the discussions as well too, so if you have any cool stuff to share with us. >> Yeah, share it around, maybe everyone can just contribute a little bit. You have your own developing pool for an awesome VoIP application. >> Yeah, great, so we will see you in the next videos coming up. I think we have one more lesson in this module. So, I hope you enjoyed seeing the VoIP application, and stay tuned.
