1. Introduction
Sunmi L2, P2Lite and other scan code special equipment, can be used for commercial
super, industrial, medical, agricultural trade, law enforcement, etc., L2 has two kinds of scan
specs:
NewLand：New NewLand Sweeping Pier, support code see Schedule 1；
Zebra：Zebra Sweeping Pier, support code see Schedule 1；
Honeywell: Honeywell Sweeping Pier, support code see Schedule 1;
Scan Engine is a development-free scanning device. By default, the side key triggers the
scan code function. There are three scan code output results. The default is the analog
keyboard output. The user opens any edit box. After the scan is successful, the scan result is
automatically entered in the edit box.
If the user needs the software to trigger the scan code or needs to customize the scan
code button, it can be set through the interface provided by the scan code service.
The following describes the interface documentation related to the scan code service
(currently support Aidl way and service connection).

2. Connect Service（AIDL）
2.1. AIDL
AIDL is the abbreviation of Android Interface Definition language. It is a description
language of Android's internal process communication interface. Through it, we can define the
communication interface between processes.
2.2. Use AIDL
Establishing a connection can be divided into the following 5 steps:
1. Add the AIDL file included in the resource file to your project.
2. Implement ServiceConnection in the code class that controls scan code.
3. Call ApplicationContext.bindService() and pass it in the ServiceConnection
implementation. Note: bindservice is a non-blocking call, meaning that the call is not
completed immediately after the call is completed. ServiceConnected must prevail.
4. In the ServiceConnection.onServiceConnected() implementation, you receive an IBinder
instance (the invoked Service). Call IScanInterface.Stub.asInterface(service) to convert
the argument to IScanInterface type.
5. Now you can call the methods defined in the IScanInterface interface.
Binding service example：
private static ServiceConnection conn = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
scanInterface = IScanInterface.Stub.asInterface(service);
Log.i("setting", "Scanner Service Connected!");
}
@Override
public void onServiceDisconnected(ComponentName name) {
Log.e("setting", "Scanner Service Disconnected!");
scanInterface = null;
}
};
public void bindScannerService() {

2.3. AIDL Interface
No.
Fuction
1
void sendKeyEvent(KeyEvent key)
Custom the trigger key
2
void scan()
start scan
3
void stop()
stop scan
4
int getScannerModel()
Get scanner type
Custom the trigger key
fuction：void sendKeyEvent(KeyEvent key)
parameter：
key →KeyEvent
action=KeyEvent.ACTION_UP：start scan
action=KeyEvent.ACTION_DOWN：stop scan
Example：
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
// Example: Use the X key value as the trigger sweep key.
if (event.getKeyCode() == x) {
scanInterface.sendKeyEvent(event);
}
return super.dispatchKeyEvent(event);
}
Start scan
fuction：void scan( )
Note：Need to work with the stop() method to start identifying scan codes.
Example：
scanInterface.scan();
