To identify all unused resources:

• Open Menu > Analyze > Run Inspection by Name...
• Select "Unused Resources"
• Make sure Whole project is checked, then press OK.
• Look through the list. You can always rerun the Inspection with the Rerun button.

There is no really easy way in Android Studio (v 1.0) to remove a resource string for all locales. However, you can search and replace in files. Fortunately, the translation files use only a single line in most cases so this works pretty well.

In Android Studio:

• Start with no changes pending in your source control (makes it way easier to check and back out if this goes wrong).
• Open Menu > Edit > Find > Replace in Path...
• In Text to find: .*name="obsoletestring".*\n
• In Replace with: (empty)
• Check Regular expression
• Press the Find button.
• Inspect the results. If okay, press the "All files" button.
• You will probably have to remove the comment in res/values/strings.xml manually.
• Make sure your project still builds.
• Take a look at the diff of your project in your source control to ensure the change is really what you intended...
