Application not showing the Arab language stored in local

Question

I am totally stuck.Please help me . I developed a hospital application which runs in two languages English and Arab. I allow the users to select language on two sections. 1.After login stage. 2.On the setting page. Whenever user selects the language ,the app runs on that language(English or Arab). The app is changing language when I run it on locally.I published the app on google playstore for testing.After that I downloaded it.When I select the arab language application is not reading the arabic values stored locally on values-ar folder. I searched the internet for two days.I did not find any answers....

I am giving you my codes....

both button click you can set prefManager.languageSelection(1); is ok or not — Pratik18, Dec 18 '18 at 05:11
Nope.On that case I am checking whether user selected any one of the two languages.If selected 1 is assigned and user navigates to home page. — Harikrishnan Jayachandran, Dec 18 '18 at 05:18
That value is stored on preference manager.Suppose user never log out the app. — Harikrishnan Jayachandran, Dec 18 '18 at 05:20
User just exit the app by clicking back button.On the next time launch I check whether user selected any one of the languages.If selected user will navigate directly from splash screen to home page. — Harikrishnan Jayachandran, Dec 18 '18 at 05:22
Otherwise I will show the language selection screen again. Bascically prefManager.languageSelection(1) is used to check whether user selected any one of the languages. — Harikrishnan Jayachandran, Dec 18 '18 at 05:24
you can try change your text, res and etc as programmatically — Pratik18, Dec 18 '18 at 05:30
you can send select language to next activity and there call setLocale method. — Pratik18, Dec 18 '18 at 05:40
Setting page is actually a fragment,Where I am restarting the home activity from fragment — Harikrishnan Jayachandran, Dec 18 '18 at 05:57
Does it work when you change the local of the device rather ten of the app? — lionscribe, Dec 18 '18 at 05:57
@HarikrishnanJayachandran can you tell me which **OS** are you testing. — Ratilal Chopda, Dec 18 '18 at 06:00

I suspect that you are uploading the app to Google as an App Bundle. When you do that, only necessary language resources for the user are installed. As the user has a non-arabic device, the Arabic resources are not installed. So changing the app locale to Arabic doesn't help, as there are no Arabic resources. If user changes device locale, then Google will download and install language, but changing app locale may be different. The simple solution is to upload to Google as APK, so that all languages are installed for all users. If you want to continue using App Bundles, you can disable the language splitting feature as per this post by adding following to build.gradle

android { 
    bundle { 
        language { 
        // Specifies that the app bundle should not support 
        // configuration APKs for language resources. These 
        // resources are instead packaged with each base and 
        // dynamic feature APK. 
        enableSplit = false 
        } 
    } 
}
