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 `` 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.
You can tell lint (and other tools) which language is the default
language in your `res/values/` folder by specifying
`tools:locale="languageCode"` for the root `` element in your
resource file. (The `tools` prefix refers to the namespace declaration
`http://schemas.android.com/tools`.)
!!! Tip
This lint check has an associated quickfix available in the IDE.

The above example was automatically extracted from the first unit test
found for this lint check, `TranslationDetector.testTranslation`.

(##) Suppressing
You can suppress false positives using one of the following mechanisms:
* Adding the suppression attribute `tools:ignore="MissingTranslation"`
on the problematic XML element (or one of its enclosing elements).
You may also need to add the following namespace declaration on the
root element in the XML file if it's not already there:
`xmlns:tools="http://schemas.android.com/tools"`.
* Using a special `lint.xml` file in the source tree which turns off
the check in that folder and any sub folder. A simple file might look
like this:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<lint>
<issue id="MissingTranslation" severity="ignore" />
</lint>
```
Instead of `ignore` you can also change the severity here, for
example from `error` to `warning`. You can find additional
documentation on how to filter issues by path, regular expression and
so on
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).
* In Gradle projects, using the DSL syntax to configure lint. For
example, you can use something like
```gradle
lintOptions {
disable 'MissingTranslation'
}
```
In Android projects this should be nested inside an `android { }`
block.
* For manual invocations of `lint`, using the `--ignore` flag:
```
$ lint --ignore MissingTranslation ...`
```
* Last, but not least, using baselines, as discussed
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
