Text Prediction in Android - With Rust 🚀

Perform next-word prediction with text-autocompletion, all in Android. The library uses Rust internally, to bring text-suggestions within a few-milliseconds. See the rust branch for more details.

Installation

1. Download text-predictor.aar from the latest release. (See Releases)
2. Move the AAR to app/libs.
3. In module-level build.gradle, add the dependency,

dependencies {
    ...
    implementation files('libs/text-predictor.aar')
    ...
}

Usage

To generate suggestions while text is being entered in a text-widget (could be a EditText or TextField), we use the stream method available in the TextPredictor class. The stream method must be called inside on a onTextChanged or a similar callback that provides a string entered by the user.

For a Compose TextField,

val textPredictor = TextPredictor( this , results )

var inputString by remember{ mutableStateOf("") }
TextField(
    modifier = modifier,
    value = inputString,,
    onValueChange = {
        textPredictor.stream(it)
        inputString = it
    },
    singleLine = true,
)

private val results: ((List<String>) -> Unit) = { suggestions ->
    // Handle UI changes that display `suggestions`
}

For a View-based EditText,

val textPredictor = TextPredictor( this , results )

editText.addTextChangedListener { it ->
    textPredictor.stream( it.toString() )
}

private val results: ((List<String>) -> Unit) = { suggestions ->
    // Handle UI changes that display `suggestions`
}
