Installation

StarMgsIO SDK library supports Maven Repository and AAR file. Please link library that suits your application configuration.

Use Maven Repository

1. Insert following code in app/build.gradle.

dependencies {
    implementation 'com.starmicronics:starmgsio:starmgsioVersion'
    ...
}

Please refer to app/build.gradle in SDK for the latest library version.

Use AAR File

1. In your app, please link starmgsio.aar located in Software/Distributables/.

2. Insert following code in app/build.gradle.

dependencies {
    implementation files('../../Distributables/starmgsio.aar')
    ...
}

Configuration

1. Please give permissions below in your AndroidManifest.xml. (These settings are related by BLE. (Required))
   Please turn ON location permission(App info -> Permissions -> Location), or make your app to ask users to turn on the permission.
   

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-permission
        android:name="android.permission.BLUETOOTH"
        android:maxSdkVersion="30" />
    <uses-permission
        android:name="android.permission.BLUETOOTH_ADMIN"
        android:maxSdkVersion="30" />

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"
        android:maxSdkVersion="30" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"
        android:maxSdkVersion="30" />

    <uses-permission
        android:name="android.permission.BLUETOOTH_SCAN"
        android:usesPermissionFlags="neverForLocation"
        tools:targetApi="31" />
    <uses-permission 
        android:name="android.permission.BLUETOOTH_CONNECT"
        tools:targetApi="31" />

    <!-- Declare this required feature if you want to make the app available to BLE-capable
         devices only.  If you want to make your app available to devices that don't support BLE,
         you should omit this in the manifest.  Instead, determine BLE capability by using
         PackageManager.hasSystemFeature(FEATURE_BLUETOOTH_LE) -->
    <uses-feature 
        android:name="android.hardware.bluetooth_le" 
        android:required="true"/>

    <application>
        ...
    </application>

</manifest>

2. Add about use of USB connection. (Optional)
   In case of check on the checkbox of connection permission dialog, then the dialog will not be displayed even if the cable is inserted or removed unless the application is reinstalled. In addition, the sample application will automatically launch when you insert the cable.

Create “device_filter.xml” in res folder.

<?xml version="1.0" encoding="utf-8"?>

<resources>
    <usb-device vendor-id="1305" product-id="4100" />
    <usb-device vendor-id="1305" product-id="4101" />
    <usb-device vendor-id="1305" product-id="4102" />
    <usb-device vendor-id="1305" product-id="4136" />
    <usb-device vendor-id="1305" product-id="4137" />
    <usb-device vendor-id="1305" product-id="4138" />
    <usb-device vendor-id="1305" product-id="4139" />
    <usb-device vendor-id="1305" product-id="4140" />
    <usb-device vendor-id="1305" product-id="4141" />
</resources>

And add next text in manifest.xml.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.starmicronics.starmgsiosdk">

    ...

    <application
        ...>
