LG Smart TV Emulator From Command Line
If you wonder if there is a way to run or debug your LG Smart TV application outside of LG IDE, lets say from command line (or Ant), I have some good news for you. It took me some time to discover the necessary requirements but thanks to WMIC and some luck I was able to run and debug the app in emulator with the web inspector.
Requirement for this process is to have LG SDK/IDE including Emulator properly installed. Natively LG IDE (eclipse) handles the process of running or debugging the app in emulator pretty smooth. Once you click run or debug button the eclipse starts local server listening on port 8080 (root is c:/*ECLIPSE-WORKSPACE*/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/*PROJECT*/), starts Safari (installed with LG SDK) within a debug perspective and opens an emulator…
All of these steps can be done manualy from command line:
lets consider you already have an local server installed, keep in mind that emulator can target your local server at IP 10.0.2.2
Web inspector is a javascript application (part of LG SDK) that can remotely listen and debug a html app running in emulator. You can run it as simple as open it in any browser (chrome worked for me)
emulator is an executable file that takes some arguments
Run In Emulator
To run the application in emulator use following .bat
SET "SDK_PATH=C:/Program Files (x86)/LG_Smart_TV_SDK"
SET APP_PATH=http://google.com
"%SDK_PATH%/Resources/jre64/launch4j-tmp/LG_Smart_TV_Emulator_2013.exe" ^
-classpath "%SDK_PATH%/LG_Smart_TV_Emulator_2013/LG_Smart_TV_Emulator_2013.exe;.;lib/vboxjmscom_4.1.jar;lib/vboxjmscom_4.2.jar;lib/jacob.jar;lib/commons-compress-1.3.jar;lib/log4j-1.2.16.jar" ^
com.dtvsdk.emul.VmEmulatorManager -b ^
%APP_PATH%If your OS is 32 bit, replace “jre64” by “jre”.
Debug In Emulator
Prior being able to use web inspector console for debugging javascript, you need to download jWebSocket and run it with proper config.
visit jwebsocket.org and download “Server” version
unzip somewhere on your drive
merge default jWebServer/conf/jWebServer.xml config file with the one from LG_Smart_TV_SDK/Resources/jWebSocket-1.0/conf/jWebServer.xml
run jWebServer
run web inspector
run emulator
It seems to be sufficient to merge following things in default jWebServer.xml file:
for each engine:
<domain>*</domain>for user with guest role
<loginname>LG_IDE</loginname>
<password>LG_IDE</password>for user with user role
<loginname>LG_DTV</loginname>
<password>LG_DTV</password>Now run the jWebServer with following attributes
SET "SDK_PATH=C:/Program Files (x86)/LG_Smart_TV_SDK"
SET "JWEBSOCKET_PATH=c:/Program Files (x86)/jWebSocket/jWebSocket-1.0"
java -jar "%JWEBSOCKET_PATH%/libs/jWebSocketServer-1.0.jar" ^
-home "%JWEBSOCKET_PATH%" ^
-bootstrap "%SDK_PATH%\Resources\jWebSocket-1.0\conf\Resources\bootstrap.xml" ^
-config "%JWEBSOCKET_PATH%\conf\jWebSocket.xml"To debug the application in emulator using web inspector use:
SET "SDK_PATH=C:/Program Files (x86)/LG_Smart_TV_SDK"
SET APP_PATH=http://10.0.2.2/your/app/index.html
"%SDK_PATH%/Resources/LGInspectorForIDE/NetCast4/inspector.html"
"%SDK_PATH%/Resources/jre64/launch4j-tmp/LG_Smart_TV_Emulator_2013.exe" ^
-classpath "%SDK_PATH%/LG_Smart_TV_Emulator_2013/LG_Smart_TV_Emulator_2013.exe;.;lib/vboxjmscom_4.1.jar;lib/vboxjmscom_4.2.jar;lib/jacob.jar;lib/commons-compress-1.3.jar;lib/log4j-1.2.16.jar" ^
com.dtvsdk.emul.VmEmulatorManager -d ^
%APP_PATH%Both, inspector and the application running in emulator connects to your jWebSocker server. It means you can remotely debug any website (e.g. google.com) running in emulator with web inspetor. For debugging the app on real TV device it may require some different steps but I will cover that in another blog post.
