Error: "app_name" is not translated in af

In your ADT go to window->Preferences->Android->Lint Error Checking

Find there MissingTranslation and change its Severity to Warning.

With Android Studio, you can prevent lint from checking the MissingTranslation warning. Add the following to your app/build.gradle:

To ignore this in a gradle build add this to the android section of your build file:

android {    ...    lintOptions {       disable 'MissingTranslation'    }    ...}

For Android Studio you can use either of the below ways to solve this issue

Method 1. Disable MissingTranslation check in build.gradle with

android {     lintOptions {        disable 'MissingTranslation'    }}

Method 2. Ignore the MissingTranslation in you resource strings file with

<?xml version="1.0" encoding="utf-8"?><resources  xmlns:tools="http://schemas.android.com/tools"  tools:ignore="MissingTranslation" >  <!-- your strings here; no need now for the translatable attribute --></resources>

Method 3. Set translatable to false on specific string with

<string name="hello" translatable="false">hello</string>
