By default, the notification's text content is truncated to fit one line. If you want your notification to be longer, for example, to create a larger text area, you can do it in this way:

A. var builder = NotificationCompat.Builder(this, CHANNEL_ID).setContentText("Much longer text that cannot fit one line...").setStyle(NotificationCompat.BigTextStyle()

.bigText("Much longer text that cannot fit one line..."))

...

B. var builder = NotificationCompat.Builder(this, CHANNEL_ID)

.setContentText("Much longer text that cannot fit one line...")

.setLongText("Much longer text that cannot fit one line..."))

...

C. var builder = NotificationCompat.Builder(this, CHANNEL_ID).setContentText("Much longer text that cannot fit one line...").setTheme(android.R.style.Theme_LongText); ...

As an example. In an Activity we have our TimerViewModel object (extended ViewModel), named mTimerViewModel. mTimerViewModel.timer method returns a LiveData value. What can be a correct way to set an observer to change UI in case if data was changed?

A. mTimerViewModel!!.timer.value.toString().observe (Observer { aLong -> callAnyChangeUIMethodHere(aLong!!) })

B. mTimerViewModel!!.timer.observe (this, Observer { aLong -> callAnyChangeUIMethodHere(aLong!!) })

C. mTimerViewModel.observe (Observer { aLong -> callAnyChangeUIMethodHere(aLong!!) })

For example, we have a file in our assets folder app/src/main/assets/sample_teas.json. To get an InputStream for reading it, from out Context context, we can try do this:

A. val input = context!!.resources.openRawResource(R.raw.sample_teas)

B. val input = context!!.assets.open("sample_teas.json")

C. val input = context!!.resources.assets.open("sample_teas.json")
