How to Use the Terminal's Bluetooth Printer Service

This service demonstrates how to use a set of Bluetooth APIs to print image or text. The integrity process of Bluetooth print service includes

ses a set of bluetooth PAI to provide a integrity function for Intents which are displayed as when a user long-presses on the app's launcher icon. Examples are given for registering both links both statically in XML, as well as dynamically at runtime.

Introduction You can use the shortcuts feature in Android 7.1 (API 25) to bring users from the launcher directly to key actions within your app. Users simply long-press your app's launcher icon to reveal the app's shortcuts, then tap on a shortcut to jump to the associated action. These shortcuts are a great way to engage users, and they let you surface the functionality of your app even before users launch your app.

Each shortcut references an intent, each of which launches a specific action or task, and you can create a shortcut for any action that you can express as an intent. For example, you can create intents for sending a new text message, making a reservation, playing a video, continuing a game, loading a map location, and much more.

You can create shortcuts for your app statically by adding them to a resource file in the APK, or you can add them dynamically at runtime. Static shortcuts are ideal for common actions, and dynamic shortcuts let you highlight actions based on users' preferences, behavior, location, and so on. This sample demonstrates both types of shortcuts.

You can offer up to five shortcuts in each of your apps.

After your app adds shortcuts, they're available on any launcher that supports them, such as the Pixel launcher (the default launcher on Pixel devices), the Now launcher (the default launcher on Nexus devices), and other launchers that provide support.

For more information on creating shortcuts, see the Shortcuts to App Actions developer guide.

Bluetooth printing is a service what terminal, which get a connection with buletooth printer,sending data to the printer through the connection and then the printer data printing the data.And the connection is built by terminal with SPP(Serial Port Profile). The process of the service:

open bluetooth if doesn't open.
scan and discovery the bluetooth devices surrounding
select and pair the bluetooth printer
send data that is a series of ESC command
printer print the data

The code was shown below: if (!mBluetoothAdapter.isEnabled()) {

     Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
     startActivityForResult(enableIntent, REQUEST_ENABLE_BT);

}
