Launcher Settings
Overview
The Launcher Settings screen provides controls for configuring the device wide user interface while using Datalogic Launcher, as well as management of configuration settings. The screen operates similar to the Android Settings application, and can be reached from the Home Screen by tapping on the Launcher Settings icon.
Allowed Packages Settings
Tapping the Allowed Packages group presents a list of all packages which are installed on the device. Items are shown in alphabetic order (by name), along with their icon. The package name is listed underneath its friendly name (if present) for easier identification of a specific package listed in a Logcat error message.
Some packages are dimmed in the listing and cannot be modified . These are packages which are already allowed by some other means. This could be due to any of the following:
- Inclusion in the Allowed Apps list. If any URLs are defined, this includes the default browser.
- Allow apps to launch other apps is enabled.
- Certain system-level packages are always allowed.
Add/Remove a package to/from the list
To add an application to the allowed list, tap the toggle to the right of the package to mark it as included.
Disabling an application from the list does not uninstall the application from the device. It only removes the entry from the list of packages the launcher allows to be run.
User Interface Settings
Tapping the User Interface group presents a screen which controls the overall user interface of the device while the launcher is running.
Home Screen Title
The Home Screen Title controls the presence of a title bar on the Home Screen and the text it displays. When empty, the title bar is not shown. Otherwise, the title bar is displayed at the top of the Home Screen.
In addition to general text, some device information may also be displayed in the title bar. To achieve this, include the appropriate tag (not case sensitive) with the text of the Home Screen Title. When detected in the title, tag is substituted for the actual information value from the device running Datalogic Launcher.
The following tags are supported:
| Information Tag | Device Value |
|---|---|
| $sn | Device serial number |
| $dev | Device name |
| $ip | IP (v4) address of Wi-Fi network |
| $eth_ip | IP (v4) address of Ethernet network |
For IP addresses, if the device does not have an IP address on the network, the result is "Disconnected". Examples of Home Screen titles are shown here:
| Title Value | Title Displayed |
|---|---|
| Warehouse Management | Warehouse Management |
| $sn | I19G00068 |
| $dev | Floor 42 |
| $dev S/N $sn | Floor 42 S/N I19G00068 |
| $ip / $eth_ip | 10.24.1.131 / Disconnected |
