Screen data

Updated

Advanced functionality can be configured by special variables added to screen data. Data variables are listed below:

 

Name Default Example Description
showStatusIcon false true Show a small status icon in the bottom right when downloading media or there are communications problems.
blackCondition false time.between("18:00", "06:59") When condition is true no images or videos will be displayed and the screen output will be black. CL
standbyCondition false   When condition is true the app will exit. Please note the device will not enter standby and turn off the screen until the sleep period configured in the Android OS. The app will restart after standbyPeriod and check the condition again. CL
standbyPeriod 3600000   The period to remain in standby. After this period the app will resume.
restartTime   03:00 The time the app should restart. Comma separated list supported. DS Loader version 12.3+ and Player version 10.7+ required. Ignored until app active for 1 minute to prevent restart loops. System clock and time zone must be correct.
exitTime   19:00 As above except app exits and does not restart.
rebootTime   00:00 As above except reboot command issued. Requires rooted device and support for reboot shell command.
background #000000 #FFFFFF The background colour to display behind other content. Also sets a colour for the video blanker which masks black video when starting and stopping videos.
videoBlankerPeriod 250 100 The period in milliseconds when a video starts and stops to display the video blanker. (requires background)
internetBlobsCondition true time.hour() == 3 When true images and videos will be downloaded from the Internet if not available on the local network. CL
intranetBlobsCondition true   When true images and videos will be downloaded from other devices on the local network. CL
blobstoreInternal true   When true internal storage will be used to store images and videos.
blobstoreExternal true   When true external storage will be used to store images and videos when the internal storage has less than 128MB available. Please note, on modern devices external storage is a second internal partition. To use an SD card or USB mass storage device you must specify the full path using blobstoreDir.
blobstoreDir   /mnt/external_sd Additional paths suitable for storing blobs. This path will be used if internal and external locations are disabled or have less than 128MB available. It is recommended that you create a directory on the storage device and use the full path because the root may be limited to 512 files. Multiple additional paths can be specified using blobstoreDir_0, blobstoreDir_1 etc.
blobTransferRateMin   10240 (10 KiB/s) The minimum acceptable transfer rate for downloading. If the transfer rate drops below this value the download will be terminated and retried later.
blobTransferRateMax   104857600 (100 MiB/s) The maximum acceptable transfer rate for downloading. Some devices can not play HD video content at full frame rate while downloading at high speed. For these devices try reducing to 1 MiB/s (1048576).
widthOverride   640 The width of the desired output. (widthOverride and heightOverriderequired)
heightOverride   480 The height of the desired output. (widthOverride and heightOverriderequired)
xOverride   100 The x position of the desired top left of output. (widthOverride and heightOverriderequired)
yOverride   100 The y position of the desired top left of output. (widthOverride and heightOverriderequired)
collectedDataTarget     A server endpoint to POST collected data such as email addresses.
webviewAllow   https://www.example.com/* Only allow the webview to access websites matching this pattern. To add multiple, suffix with a number starting with _0. E.g. webviewAllow_0=... webviewAllow_1=.... This setting restricts main address and iframe addresses but not resources loaded by the page.
webviewReuse   10 The number of WebView components to cache and reuse. Speeds up rendering web pages that display more than once. Set to 0 to disable.
webviewReusePeriod   600000 The period in milliseconds a cached WebView should reuse content and avoid reloading the page.
maxBitmapCacheSize   20000000 The maximum RAM (in bytes) that will be used to cache bitmap images. Default is half memMax.
manageSystemUiVisibility true false Attempt to hide the System UI. Disable this option if touch events are ignored.
password   password Adds a password field to the exit dialog. Password typed must match this password to exit.
encryptPlayerComms   true Forces player communications to use an encrypted and digitally signed connection.

CL = Conditional logic supported, for example time.between("18:00", "06:59") will automatically enable the setting between 6pm and 6:59am.

Screen data sent by players

Devices will periodically send the following data to the server. This data can be used in conditions to control if an item displays. For example the condition screenWidth > 1000 would ensure the item only displays if the width of the screen is greater than 1000 pixels.
