Pre-requirements

SUNMI POS Model number is P1N or P1-4G or P2PRO or P2 Lite SE (Check Seeting-->About-->Mode number)
SUNMI PayHardware Service (SPHS) SDK. Version 3.3.0 or the lastest version. SunmiPayHardwareService_v3.3.0_release.apk
- Go to Setting in the Device → Then search in the bar “SunmiPayHardwareService” → Click on it → Click on the button Advanced → In the advanced section, check the version of the SPHS SDK.

Android Studio Quick integrate, Put the PayLib-release-xxx.aar package under the libs folders of your App.

repositories {
      flatDir {
      dirs 'libs'
  }
}
dependencies {
  ......
  compile(name: 'PayLib-release-xxx', ext: 'aar')
}

Warning

PayLib-release-xxx.aar package: This is a package which must be used carefully. Only use it to disable the Android Nav Bar, not for any other function (example payments functions). In case you have any doubt please reach out the PayXpert teams.
If merchant app/integrator disables the navigation bar, they will need to implement a fonctionality that will allow to activate it temporary. Otherwise, the POS will be blocked in case there is a manual intervention that needs to be done on the POS Device.

The variable to desactivate the Nav Bar via SUNMI is shared between merchant app and payXpress app.
By Default, PayXpress app deployed in the P2 LITE SE / P2 PRO devices will activate the Nav Bar in the standbyscreen (initial screen) and then it will disable it during the payment transaction. Once the payment has been finalize it will be activated it back automatically.
