Brackets "trick" (good or bad?)

So.. in this lesson we using brackets trick to make double value String //mHumidityValue.setText(mCurrentWeather.getHumidity() + ""); In new Android Studio warning message appears:

  • Do not build messages by concatenating text chunks. Such messages can not be properly translated.

Q: Is it normal to use such transformation in TextView.setString() method (and others)?

The error doesn't apply to what you're doing. It's saying that if you had something in the double quotes - like "% humidity" - then that text would always be in English; it couldn't be translated using the standard Android practice of string resource files for each language.

It's fine for what you're doing (no text - just an empty string). Check out Android string resources if you want more info.
