With ADT 16 you can do it as simple as possible. Update to ADT 16 and use Android Lint. It is really amazing tool. It can find all unused resources (not only strings) and many more. From its official site:

有了adt16，你可以做的尽可能简单。更新到adt16并使用Android Lint。这是一个非常棒的工具。它可以找到所有未使用的资源(不仅仅是字符串)和更多的资源。从其官方网站:

Here are some examples of the types of errors that it looks for:

- Missing translations (and unused translations)
- Layout performance problems (all the issues the old layoutopt tool used to find, and more)
- Unused resources
- Inconsistent array sizes (when arrays are defined in multiple configurations)
- Accessibility and internationalization problems (hardcoded strings, missing contentDescription, etc)
- Icon problems (like missing densities, duplicate icons, wrong sizes, etc)
- Usability problems (like not specifying an input type on a text field)
- Manifest errors
and many more.

In my case "Run Inspection by Name" didnt work, despite the fact I was using "Remove unused resources".

在我的例子中，“按名称运行检查”不起作用，尽管我正在使用“删除未使用的资源”。

Solution:

解决方案:

Open strings.xml
打开strings.xml
Secondary click
二次点击
Refactor --> Remove Unused Resources
重构——>删除未使用的资源

I have no clue why "Remove Unused Resources" works one way but not the other.

我不知道为什么“删除未使用的资源”是一种方式，而不是另一种方式。

Take a look at my question: Find out if resource is used

看看我的问题:看看是否使用了资源

As nobody had a real answer, I programmed a script to search for unused resources which includes strings, too.

由于没有人有真正的答案，我编写了一个脚本来搜索包含字符串的未使用资源。

Hope that helps you.

Run this script from root of your project.

从项目的根目录运行这个脚本。

for resourcefile in `find res/values/*.xml`; do
  for stringname in `grep '.*/\1/g'`; do
    count1=`grep -rc "R.string.${stringname}" src | egrep -v ':0$' | wc -l`
    count2=`grep -rc "@string/${stringname}" res/layout | egrep -v ':0$' | wc -l`
    count3=`grep -rc "@string/${stringname}" res/menu | egrep -v ':0$' | wc -l`
    count4=`grep -rc "@string/${stringname}" AndroidManifest.xml | egrep -v '^0$' | wc -l`
    count5=`grep -rc "@string/${stringname}" res/xml | egrep -v ':0$' | wc -l`
    if [ $count1 -eq 0 -a $count2 -eq 0 -a $count3 -eq 0 -a $count4 -eq 0 -a $count5 -eq 0 ]; then
      echo $resourcefile : $stringname
    fi
  done
done

for resourcename in `find res/drawable* -type f -name '*.???'`; do
  resource=`echo $resourcename | xargs basename | sed "s/^\(.*\)\....$/\1/g"`
  count1=`grep -rc "R\.drawable\.${resource}" src | egrep -v ':0$' | wc -l`
  count2=`grep -rc "@drawable/${resource}" res/layout | egrep -v ':0$' | wc -l`
  count3=`grep -rc "@drawable/${resource}" res/drawable*/*.xml | egrep -v ':0$' | wc -l`
  count4=`grep -rc "@drawable/${resource}" res/menu | egrep -v ':0$' | wc -l`
  count5=`grep -rc "@drawable/${resource}" AndroidManifest.xml | egrep -v '^0$' | wc -l`
  if [ $count1 -eq 0 -a $count2 -eq 0 -a $count3 -eq 0 -a $count4 -eq 0 -a $count5 -eq 0 ]; then
      echo $resourcename
  fi
done

for resourcename in `find res/layout/*.xml`; do
  resource=`echo $resourcename | xargs basename | sed "s/^\(.*\)\....$/\1/g"`
  count1=`grep -rc "R\.layout\.${resource}" src | egrep -v ':0$' | wc -l`
  if [ $count1 -eq 0 ]; then
      echo $resourcename
  fi
done

It gives me this kind of output:

它给了我这样的输出:

res/values/activity_strings.xml : activity_more
res/values/activity_strings.xml : activity_as_reply_to
res/values/db_strings.xml : sql_backlog_count
res/values/db_strings.xml : sql_backlog_update_last_resend
...
