Is it necessary to make these uppercase? Will Android make the button text
uppercase automatically? For instance, R.string.login_dialog_ok_button_label in
LoginPrompt.java is not uppercase.

In the Play Store, the green button of "INSTALL" is uppercase, and I guess this
is where Sam's UI design initially comes from?

[pkotwicz, 2017/06/06 15:21:47]

I meant: Won't the Android framework make the word uppercase on the button even
if the word is lowercase here?

Yes, it is auto converted to uppercase. I still think it is safer to use the
uppercase here to avoid any unexpected things during translation.
