Question

I am learning Android, and I have what I think is a weird problem.

in /res/values/strings.xml I have:

<string name="titleStatus">Status Update</string>

in /res/layout/activity_status.xml I have:

<!-- Title TextView-->
<TextView android:layout_width="match_parent"
  android:layout_height="wrap_content" android:gravity="center"
  android:textSize="30sp"
  android:layout_margin="10dp" android:text="@string/titleStatus"/>

However, when viewing activity_status.xml I am getting error:

Error: No resource found that matches the given name (at ‘text’ with
value ‘@string/titleStatus’). activity_status.xml

I then figured it could possibly help use “Project | Clean”, but I get the same problem (and now without the auto-generated R.java class)

I am following this tutorial/book:

Whenever you add something to a resource file and try to use it in another without saving it first, you will get an error.

The normal ctrl+s just saves the file you’re in, so compilation will occur without the changes in the other file.

Pressing ctrl-shift-s saves changes in all open files (same as going to File -> Save All).

Personally, I hit ctrl-shift-o, ctrl-shift-f and ctrl-shift-s everytime I need to save some changes to organize the imports, format the code to fix indenting etc. and to save all changes.
