To make the code more concise and idiomatic, you can use the let scope function with an elvis operator to handle the nullable chooserResult.

            chooserResult?.let {
                Log.i(TAG, "isShortcut: ${it.isShortcut}")
                Log.i(TAG, "type: ${typeToString(it.type)}")
                Log.i(TAG, "componentName: ${it.selectedComponent}")
            } ?: Log.i(TAG, "chooserResult is null")

} else {
// This ComponentName represents the Activity that has received the data we shared.
val componentName: ComponentName? = IntentCompat.getParcelableExtra(
intent,
Intent.EXTRA_CHOSEN_COMPONENT,
ComponentName::class.java,
)
Log.d(TAG, "componentName: $componentName")
}
}

private fun typeToString(type: Int): String {
return when (type) {
CHOOSER_RESULT_SELECTED_COMPONENT -> "SELECTED_COMPONENT"
CHOOSER_RESULT_COPY -> "COPY"
CHOOSER_RESULT_EDIT -> "EDIT"
CHOOSER_RESULT_UNKNOWN -> "UNKNOWN"

The when expression can be simplified. The CHOOSER_RESULT_UNKNOWN case is redundant because the else branch already handles it and any other unknown values by returning "UNKNOWN". Removing the explicit case makes the code more concise.

        return when (type) {
            CHOOSER_RESULT_SELECTED_COMPONENT -> "SELECTED_COMPONENT"
            CHOOSER_RESULT_COPY -> "COPY"
            CHOOSER_RESULT_EDIT -> "EDIT"
            else -> "UNKNOWN"
        }

}

The string "Hello, world!" is hardcoded here and also in the else branch on line 122. To follow the DRY principle and improve maintainability, extract this string into a constant (e.g. private const val PLAIN_TEXT_CONTENT = "Hello, world!") and use it in both places. You will need to update line 122 as well.

Suggested change
share.putExtra(Intent.EXTRA_TEXT,"Hello, world!")
share.putExtra(Intent.EXTRA_TEXT, PLAIN_TEXT_CONTENT)

Avoid using magic numbers for request codes. Extract 1234 into a named constant at the file level (e.g., private const val SHARE_TEXT_REQUEST_CODE = 1234) to improve code clarity and maintainability.
