How to delete an unused string resource for all configurations in Android Studio?
I've found an unused string resource, like:
<string name="obsoletestring">my name is null!</string>
However it is in tens of files, of different languages, in different strings.xml files in values, values-af, values-be, etc folders.
I must have missed something not to know any way to do this in Android Studio other than modifying it by hand one by one.
tl;dr How to delete an unused string resource for all configurations?
Answer
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...
