__NOTOC__
== Introduction ==
The following document will highlight the steps needed to run Browser SDK (BSDK) on Samsung Smart TV using TIzen Studio for app development.
The tutorial should be used in conjunction with the documentation at [https://docs.tizen.org/application/web/get-started/tv/first-samsung-tv-app/ Create Your First Samsung Smart TV Web Application] to build an app with BSDK integration for content measurement. In this tutorial we will create a native app and highlight the different permissions required to run the BSDK.

== Step 1: Install Tizen Studio ==

Navigate [https://developer.tizen.org/development/tizen-studio/download here] and install Tizen Studio.
During installation make sure to install the '''TV Extensions package''' from the Package Manager.

== Step 2: Generate Security Profile ==

Navigate [https://docs.tizen.org/application/tizen-studio/common-tools/certificate-registration here] and generate the security profile in order to run applications.

== Step 3: Create Basic Project ==

Follow the [https://docs.tizen.org/application/web/get-started/tv/first-samsung-tv-app/ step-by-step guide] and create the Basic Project template.
Replace the code in the<syntaxhighlight>index.html</syntaxhighlight>file with the code snippet below and update the App ID with a Nielsen provided App ID during SDK initialization.

==Step 4: Run Project==
<syntaxhighlight lang="javascript">Right click on the project > Run As > Tizen Web Simulator Application (Samsung TV)</syntaxhighlight>
<br>
[[File:Tizen 1 Step4.png||600px|center|]]
<br>
Extra configurations must be done to run and debug the application on a Target Device, please reference the following [[TizenTv_Debugging|guide]] for more information

== Step 5: Debug App==
Right click anywhere in the Simulator to open the Web Inspector > navigate to the Console tab > check for BSDK initialization and content measurement.
[[File:Tizen 1 Step5.png||600px|center|]]

Debug Logging: Disable logging by deleting <syntaxhighlight lang="javascript">{nol_sdkDebug: 'debug'}</syntaxhighlight> from initialization call

== Remote control events ==
Build out the app further by including [https://developer.samsung.com/smarttv/develop/guides/user-interaction/remote-control.html remote control events] and attaching the player events to corresponding <syntaxhighlight lang="javascript">keyCode </syntaxhighlight> or using Tizen registered keys:
<syntaxhighlight lang="javascript">

var media = document.querySelector('video');
window.addEventListener("keydown", function (e) {
switch (e.keyCode) {
case 10252: // MediaPlayPause
if(!media.paused) {
media.pause(); // pause video
nSdkInstance.ggPM("pause", playheadPosition); // SDK call
break;
}

media.play(); // play video
nSdkInstance.ggPM("play", contentMetadata); // SDK call
break;
case 10009: // Back
nSdkInstance.ggPM("stop", playheadPosition); // SDK call
break;
...
default:
break;
}
});

</syntaxhighlight>
