问题


Toast does not work in Android Q. Is there any change on Toast? I couldn't find any release note for Toast.
My code is simple.

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    Toast.makeText(this, "onCreate", Toast.LENGTH_SHORT).show()
}

fun onButtonClick(view: View) {
    Toast.makeText(this, "onButtonClick", Toast.LENGTH_SHORT).show()
}

This works fine with Android Pie, but no luck with Android Q.
What happened to Toast??

As described in this Answer, make sure you haven't disabled notifications for the application. Go to App settings and see that notifications are enabled.
