Lib usbserial for Qt Android (No need root device)

JAVA Wrapper with Qt6's QJniObject Class

1. Add library to your project:

Add jitpack.io repository to your root build.gradle:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Starting with gradle 6.8 you can alternatively add jitpack.io repository to your settings.gradle:

dependencyResolutionManagement {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add library to dependencies

dependencies {
    implementation 'com.github.mik3y:usb-serial-for-android:3.4.6'
}

2. If the app should be notified when a device is attached, add device_filter.xml to your project's res/xml/ directory and configure in your AndroidManifest.xml.

<activity
    android:name="..."
    ...>
    <intent-filter>
        <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
    </intent-filter>
    <meta-data
        android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
        android:resource="@xml/device_filter" />
</activity>

3. Add folder jniusbserial to your project's andorid/src/org/qtproject/ directory and androidserial to project directory.

4. Use it like Qt's QtSerialPort library, which is just enough for basic functions.

The app uses the usb-serial-for-android library.
