  <pre><code>"common_google_play_services_unknown_issue" is not translated in af, am, ar, be, bg, ca, cs, da, de, el, en-rGB, es, es-rUS, et, fa, fi, fr, hi, hr, hu, in, it, iw, ja, ko, lt, lv, nb, nl, pl, pt, pt-rPT, ro, ru, sk, sl, sr, sv, sw, th, tl, tr, uk, vi, zh-rCN, zh-rTW, zu
  
  Issue: Checks for incomplete translations where not all strings are translated Id: MissingTranslation
  
  If an application has more than one locale, then all the strings declared in one language should also be translated in all other languages.
  
  If the string should not be translated, you can add the attribute translatable="false" on the &lt;string&gt; element, or you can define all your non-translatable strings in a resource file called donottranslate.xml. Or, you can ignore the issue with a tools:ignore="MissingTranslation" attribute.
  
  By default this detector allows regions of a language to just provide a subset of the strings and fall back to the standard language strings. You can require all regions to provide a full translation by setting the environment variable ANDROID_LINT_COMPLETE_REGIONS.
