=== Enable remote control in custom build === | |||
Remote control is for Firefox OS TV, so it's only available when you add the following line to mozconfig: | |||
ac_add_options --enable-remote-control-service | |||
Gecko uses the macro '''MOZ_B2G_REMOTECONTROLSERVICE''' to enable remote control in following files: | |||
* b2g/app/b2g.js | |||
* b2g/installer/package-manifest.in | |||
* b2g/chrome/jar.mn | |||
* b2g/chrome/content/shell.html | |||
* b2g/moz.build | |||
* b2g/components/moz.build | |||
* toolkit/modules/AppConstants.jsm | |||
Use '''AppConstants.MOZ_B2G_REMOTECONTROLSERVICE''' in following file: | |||
* b2g/chrome/content/settings.js | |||
== Architecture Design == | |||
=== Service start/stop === | |||
# shell.html includes chrome://b2g/content/remote_control.js | |||
# remote_control.js reads Gecko preference '''remotecontrol.service.enabled''', if true, start service | |||
# remote_control.js monitors the preference to start/stop service | |||
=== Gaia MozSettings mapping === | |||
User can use remote control app to start/stop service. But the app only write changes to MozSettings, service monitors Gecko preference to start/stop. | |||
In settings.js, function '''setupRemoteControlSettings''' monitors MozSettings '''remote-control.enabled''' and write the value to Gecko preference '''remotecontrol.service.enable'''. | |||
