"noinspection" keyword list in Android Studio

Question

In Android Studio I sometimes use this kind of comment to disable an inspection warning on a specific line of code that I already handled, for example:

if(Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
    //noinspection deprecation
    textView.setBackgroundDrawable(ContextCompat.getDrawable(mContext, R.drawable.calendar_item_separator));
} else {
    textView.setBackground(ContextCompat.getDrawable(mContext, R.drawable.calendar_item_separator));
}

In this example I used the keyword "deprecation" but I cannot find the full list of available keywords.

Did anyone find out?

Thanks!

Answer 1

I finally succeeded to get the keywords list from this Github source code.

I paste it here just in case:

For a reason I still don't know, the use of the comment //noinspection <keyword> does not work all the time.

To be able to use the keyword UnusedDeclaration I had to write this line before my variable declaration:

/** @noinspection UnusedDeclaration */
private static final String TAG = "DateTools";

I might be wrong, but I think the closest you can get is the Inspections view in Android Studio's settings. Hit Ctrl + Alt + S, choose Editor -> Inspections.

It will not show you the list of available noinspection keywords, but it'll provide you the full list of inspections available in Android Studio.

BTW, why would you need that in the first place? Any time the warning is shown in the Android Studio, there is this quick-fix option available by Alt + Enter which shows you how this warning can be suppressed.
