Answer : The link you are referring to seems to work with strings generated at runtime. The strings from strings.xml are not created at runtime. You can get them via String mystring = getResources().getString(R.string.mystring); getResources() is a method of the Context class. If you are inside a Activity or a Service (which extend Context) you can use it like in this snippet. Also note that the whole language dependency can be taken care of by the android framework . Simply create different folders for each language. If english is your default language, just put the english strings into res/values/strings.xml . Then create a new folder values-ru and put the russian strings with identical names into res/values-ru/strings.xml . From this point on android selects the correct one depending on the device locale for you, either when you call getString() or when referencing strings in XML via @string/mystring . The ones from res/values/strings.xml are the fallback ones, if y

The :defined CSS pseudo-class represents any element that has been defined. This includes any standard element built in to the browser, and custom elements that have been successfully defined (i.e. with the CustomElementRegistry.define() method). /* Selects any defined element */ :defined { font-style : italic ; } /* Selects any instance of a specific custom element */ simple-custom:defined { display : block ; } Syntax :defined Examples Hiding elements until they are defined The following snippets are taken from our defined-pseudo-class demo ( see it live also).

Answer : In my case in Android 2.2, for some reason, Firebase was selected by default in the dropdown box marked above. So logs didn't drop. I just needed to change it to No Filters . Then it worked. I even tried restarting the logcat, that didn't work too. No Filters did the magic. Hope this helps someone. Edit : You can as well select Show only selected application for logcat to show only the current debugging process, i.e your app. You may be hiding it, try pressing Alt + 6 to open Log tab. Look at the log level:- it must be verbose. Restart adb. If that doesn't works restart the android studio. In Logcat window reselect your device then reselect your app if it didn't appear restart adb using two commands: adb kill-server adb start-server Happy debugging :)
