I'm looking to wait for a coroutine to finish before continuing with some other processes. From what I've found in Kotlin and Android documentation,

async

would be my best bet since it returns a

Deferred

that "represents a promise to provide a result later." However, I am not looking to wait for a result to be return. While I know I could probably return a dummy value (probably a boolean to represent the coroutine finished), are there any other alternatives to

async

?

Just make the function suspend.

Code:

suspend fun extractTextFromFilePath(filePath: String): Boolean {

// code

}

class CameraViewModel(val context: Context): ViewModel() {

private var textBlocks = mutableMapOf<String, Array<Point?>>()

val textBlockString

get() = textBlocks.toString()

fun extractText(filePath: String): String {

viewModelScope.launch {

imageAnalyzer.extractTextFromFilePath(filePath)

}

Log.d(TAG, textBlockString)

return extractedText

}

}
