Getting Started with a Launcher.JSON
Launcher Setup
The most streamlined method for configuring a fleet of devices for BlueFletch Enterprise, or for updating any number of those devices simultaneously, is through the BlueFletch Portal website and Playbook Agent application. The launcher.json file can be written in an editor wizard on the Portal. Detailed directions for the process can be found here. However, there may come be some instance when you need to manually write the launcher.json file and install the JSON and Launcher application directly onto a device, for which we have provided the following guide.
Build Configuration
To start, you need a launcher.json file. Using the BlueFletch Portal, this can be easily generated. The Portal will pre-fill the current license key and organization ID; if creating the launcher.json manually, the license key and organization ID can be found on the Organization page of the Portal, within the Admin tab.
There is an example configuration in the Configurations documentation and another one at the bottom of this page.
Setup the License Key
Retrieve your license key from the BlueFletch Portal, or ask your BlueFletch contact for it, and place it in the configuration file as follows:
{
"configVersion" : "2020-01-01-start",
"license" : "paste license key here",
...
}
It is suggested that the configVersion is updated each time the configuration file is touched. This field is for reference only.

Applications
To assign applications to display in specific groups, identify the groups that will be returned from your Identity Provider. In the example below, we expect to get both Supervisor and Associates as the named groups. Set up these user groups in the layout fields. To add a package to a group, add a JSON object with the package field.
...
"layouts" : {
"Supervisor": [
{ "package" : "com.bluefletch.ems.support" },
{ "package" : "com.android.calculator2" }
],
"Associates" : [ ... ],
"*" : [ ... ]
},
...
In the above example:
- Supervisors will see the two apps from the 'Supervisor' array.
- Associates will see apps from 'Associates' array only.
- Non logged-in users will see the apps in the '*' or open zone section.

Web Shortcuts
To specify a website shortcut, add a JSON object that defines a label and url, and any optional values as desired, inside of a layout:
...
"layouts" : {
"Supervisor": [
{
"label" : "BlueFletch Web",
"url" : "https://bluefletch.com",
"icon" : "/sdcard/DCIM/icons/bluefletch_logo.png"
}
],
"Associates" : [ ... ],
"*" : [ ... ]
},
...

Folders
To create a folder, you will need to specify the label and the contents, which will contain the different apps in the folder. You can use the same syntax for the application object inside the contents of the folder. This example puts some Supervisor applications inside "App Folder":
...
"layouts" : {
"Supervisor": [
{
"label" : "App Folder",
"contents" : [
{ "package" : "com.bluefletch.ems.support" },
{ "package" : "com.android.calculator2" },
{ "label" : "BlueFletch Web", "url" : "https://bluefletch.com",
"icon" : "/sdcard/DCIM/icons/bluefletch_logo.png"
}
]
},
{ "package" : "com.google.calendar" }
],
"Associates" : [ ... ],
"*" : [ ... ]
},
...

Install Configuration
Copy the launcher.json file to the following location:
/sdcard/Download/ems/launcher.json
Launcher will pick this file up and copy it to:
/sdcard/Android/data/com.bluefletch.launcher/files/blueLauncher/launcher.json
Additionally the Launcher will monitor for any changes to these locations and reapply to the application.
Install Application
Download the Launcher APK from the BlueFletch Portal Downloads page, and install the APK via your MDM or sideload via ADB.
adb install ./launcher.apk
The package com.bluefletch.launcher will be installed.
It is suggested that Permissions be granted prior to launching the application.
Permissions via ADB
adb shell pm grant com.bluefletch.launcher android.permission.READ_PHONE_STATE
adb shell pm grant com.bluefletch.launcher android.permission.RECEIVE_BOOT_COMPLETED
adb shell pm grant com.bluefletch.launcher android.permission.READ_EXTERNAL_STORAGE

afw_set_permission_grant_state com.bluefletch.launcher android.permission.NFC allow
afw_set_permission_grant_state com.bluefletch.launcher android.permission.SYSTEM_ALERT_WINDOW allow
Start Launcher
To start, use com.bluefletch.launcher.Launcher
Example ADB Command
adb shell am start -n com.bluefletch.launcher/com.bluefletch.launcher.Launcher
Example AirWatch Command
mode=explicit,action=android.action.intent.MAIN,package=com.bluefletch.launcher,class=com.bluefletch.launcher.Launcher,broadcast=false
On first execution, the Enterprise Launcher APK will set itself as the default launcher and reboot the device.
