Multi lingual support for Android 7.0 and above does not work

Starting in Android 7.0, Android language and locale support for multilingual users was improved.

https://developer.android.com/guide/topics/resources/multilingual-support.html

But it does not work exactly what I thought.

Here is res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.tistory.httphckim999.languageprioritytest.MainActivity"
    android:orientation="vertical">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/first_test" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/second_test" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/third_test" />
</LinearLayout>

Here is res/values/strings.xml

<resources>
    <string name="app_name">Language Priority Test</string>
    <string name="first_test">first default</string>
    <string name="second_test">second default</string>
    <string name="third_test">third default</string>
</resources>

Here is res/values-ko/strings.xml

<resources>
    <string name="first_test">first ko</string>
</resources>

Here is res/values-zh/strings.xml

<resources>
    <string name="second_test">second zh</string>
</resources>

And here is res/values-ja/strings.xml

<resources>
    <string name="third_test">third ja</string>
</resources>

And my test devices locale setting priority is "ko > zh > ja"

I think it should be print like this.

first ko

second zh

third ja

But it was printed like this

first ko

second default

third default

I can't understand why it was printed like this.

I upload my test project here.

https://github.com/kimhc999/LanguagePriorityTest

I tested it in Galaxy S7(7.0), PIXEL(8.0 Preview 3), and emulators(7.0, 7.1, 8.0). But all of them have same result.

Can anyone help me?

Thank you.

It is working in expected way, you are perceiving it in wrong way. In your app default language is English and you placed all values in strings.xml as following

<resources>
    <string name="app_name">Language Priority Test</string>
    <string name="first_test">first default</string>
    <string name="second_test">second default</string>
    <string name="third_test">third default</string>
</resources>

Language of your phone is ko and you placed only 1 value for that

Here is res/values-ko/strings.xml

<resources>
    <string name="first_test">first ko</string>
</resources>

When you run the application it will first search for value in values-ko folder and if value isn't available there then default value will be picked from values/strings.xml which is english in your case.

As only first_test is available in values-ko so for second_test and third_test it will pick values from default values folder and you are getting right result:

first ko

second default

third default
