1 # Demo Mode for the Android System UI 2 *Demo mode for the status bar allows you to force the status bar into a fixed state, useful for taking screenshots with a consistent status bar state, or testing different status icon permutations. Demo mode is available in recent versions of Android.* 3 4 ## Enabling demo mode 5 Demo mode is protected behind a system setting. To enable it for a device, run: 6 7 ``` 8 adb shell settings put global sysui_demo_allowed 1 9 ``` 10 11 ## Protocol 12 The protocol is based on broadcast intents, and thus can be driven via the command line (```adb shell am broadcast```) or an app (```Context.sendBroadcast```). 13 14 ### Broadcast action 15 ``` 16 com.android.systemui.demo 17 ``` 18 19 ### Commands 20 Commands and subcommands (below) are sent as string extras in the broadcast 21 intent. 22 <br/> 23 Commands are sent as string extras with key ```command``` (required).
