Usage with Jetpack Compose?

[Myzel394]

I don't know whether this is a mistake on my side, but I don't know how create a State with Jetpack Compose.

So I got a audio recording app and I want the user to be able to detect what state it is currently running.

@TaskerInputRoot
class AudioRecorderInput(
    @field:TaskerInputField(VAR_STATE, labelResIdName = "ui_audioRecorder_recordingState_label") var state: String? = null
) {
    companion object {
        const val VAR_STATE = "audioRecorderState"
    }
}

@TaskerOutputObject
class AudioRecorderOutput(
    @get:TaskerOutputVariable(VAR_STATE, labelResIdName = "ui_audioRecorder_recordingState_label") val state: String = RecorderState.IDLE.name
) {
    companion object {
        const val VAR_STATE = "audioRecorderState"
    }
}

Then, in the runner I check whether the given state by the user matches the current state:

class AudioRecorderRunner : TaskerPluginRunnerConditionState<AudioRecorderInput, AudioRecorderOutput>() {
    override fun getSatisfiedCondition(context: Context, input: TaskerInput<AudioRecorderInput>, update: Unit?): TaskerPluginResultCondition<AudioRecorderOutput> {
        return if (state.name == input.regular.state)
            TaskerPluginResultConditionSatisfied(context)
        else TaskerPluginResultConditionUnsatisfied()
    }

    companion object {
        var state: RecorderState = RecorderState.IDLE
        fun change(context: Context, newState: RecorderState) {
            state = newState
            AudioRecorderActivity::class.java.requestQuery(context)
        }
    }
}

This is the helper:

class AudioRecorderHelper(config: TaskerPluginConfig<AudioRecorderInput>) : TaskerPluginConfigHelper<AudioRecorderInput, AudioRecorderOutput, AudioRecorderRunner>(config) {
    override val runnerClass = AudioRecorderRunner::class.java
    override val inputClass = AudioRecorderInput::class.java
    override val outputClass = AudioRecorderOutput::class.java
}

and in the activity I show a dropdown for the user to select from - but how do I pass that information back to Tasker?

class AudioRecorderActivity : AppCompatActivity(), TaskerPluginConfig<AudioRecorderInput> {
    override val inputForTasker: TaskerInput<AudioRecorderInput>
        get() = TaskerInput(AudioRecorderInput(selectedState.name))

    override val context: Context
        get() = applicationContext

    override fun assignFromInput(input: TaskerInput<AudioRecorderInput>) {
        // println("test") // Does not seem to be called
        input.regular.run {
            selectedState = RecorderState.valueOf(state ?: RecorderState.IDLE.name)
        }
    }

    var selectedState by mutableStateOf(RecorderState.IDLE)

    override fun onStart() {
        super.onStart()

        WindowCompat.setDecorFitsSystemWindows(window, false)

        setContent {
            var selectedState by remember { mutableStateOf(RecorderState.IDLE) }

            AlibiTheme {
                Column(
                    modifier = Modifier
                        .fillMaxSize()
                        .background(MaterialTheme.colorScheme.background)
                        .padding(horizontal = 16.dp, vertical = 32.dp),
                    horizontalAlignment = Alignment.CenterHorizontally,
                    verticalArrangement = Arrangement.SpaceBetween,
                ) {
                    Box {}
                    Text(
                        "Configure Audio Recorder State",
                        style = MaterialTheme.typography.headlineLarge,
                        color = MaterialTheme.colorScheme.onBackground,
                        textAlign = TextAlign.Center,
                    )
                    Box {}

                    var opened by remember { mutableStateOf(false) }
                    Column {
                        Box {
                            Button(
                                onClick = {
                                    opened = true
                                },
                                colors = ButtonDefaults.filledTonalButtonColors(
                                    containerColor = MaterialTheme.colorScheme.surfaceColorAtElevation(
                                        4.dp
                                    ),
                                ),
                                shape = MaterialTheme.shapes.small,
                            ) {
                                Text(

                                )
                            }
                            DropdownMenu(
                                expanded = opened,

Hi! I'm very sorry for taking so long to respond. I must've missed this somehow! Were you able to figure it out?

Looking at your code real quick it seems like you're doing it right... You should call finishForTasker() which will then get your input from inputForTasker.

Let me know, thanks!

Unfortunately, I was not able to figure it out. It's been a while since I've worked on the code, but I will definitely take a look at it later as I still would like to add Tasker support :D

Won't happen today or tomorrow, I'll ping you once I've tried it out and taken a closer look at it.

[joaomgcd]

Thanks :) But I think you have the right idea. Must be something small that's missing somewhere...

Very late, but I'm pretty sure your issue is that you have selectedState defined again inside setContent {}. Kotlin supports name shadowing and selects the variable in the smallest possible scope, so that second selectedState is what you're updating in the UI. Deleting that should work.
