Hi, i implemented language change on my app, everything works fine but i received report about problem on Android 5.1, on this version is language change do nothing, just refresh activity and whole content remain in default language.

Does anybody face similar issue ? or this version and lower are not supported ?
Thanks upfront for any help :)

I just discovered on a device by Xiaomi with MIUI12 that translations may be missing if you publish the app on Google Play as AAB (Android App Bundle). After changing to the traditional APK everything was OK. I believe, when using AAB Google Play only installs the language which is used by the device - as the idea of AAB is to save storage space.

Maybe this should be mentioned in the documentation.

Здравствуйте
Я использую вашу библиотеку в своем приложении, но на некоторых устройствах в некоторых местах текст не меняется. В этих устройствах всё хорошо работает, если полностью закрою приложение и заново в него войду. У себя в проекте я использую библиотеку Conductor вместо фрагментов. Мы про тестировали это на нескольких устройствах. Могу скинуть скриншоты и марку телефонов на которых оно проявляется.

Код Application класса как я инициализироваю Lingver:

@Override
    public void onCreate() {
        super.onCreate();
        Lingver.init(this, new PreferencesHelper(this, new Gson()).getLocale()); 
}

Это код после смены языка пользователем:

@Override
    public void changeLanguage(@NotNull String lang) {
        Lingver.getInstance().setLocale(binding.getRoot().getContext(), lang);
        getActivity().recreate();
    }

target 30 not working

In some recently-released phones, users cannot change the language inside the app which is using lingver, the language is not independent of the OS language.

This happens in samsung A10, api 29 and xiaomi redmi k20 pro api 29
But It works fine in Samsung j7Pro api 28

Maybe it's an issue in api level?

Hi,
I've testing the library to change language programatically and it works perfectly. The problem is when I put the app on Google Play. The same app doesn't work, doesn't change the language.

I've tried 2 times, it's exactly the same app on local and Google Play.

Anyone with same issue?

Thanks a lot!

I've set the locale with this code:
Lingver.getInstance().setLocale(requireContext(), "fa")
It use RTL layout direction. Everything works great, but when I use the app in split screen mode and then maximize it again layout direction resets to LTR (but it uses farsi strings).

How can I fix the issue?

I don't know if this is a problem with me using this library in Java project, or am I missing something? I just want to get default system locale (the phone's locale).

Lingver.getInstance().systemLocale.getLanguage();

error: systemLocale has private access in Lingver

I also tried:

Lingver.defaultLocale.getLanguage();

error: defaultLocale has private access in Lingver

Then there is getSystemLocale$com_yariksoffice_lingver_library():

Usage of Kotlin internal declaration from different module

We're seeing a lot of ANRs being reported that are caused by Lingver init call. This is occurring during the process creation time (cold start), when calling Lingver.init(context) on the Application.onCreate

Unable to repro this. Is there any resolution to this?

            overrideConfiguration.uiMode = uiMode;
        }
        super.applyOverrideConfiguration(overrideConfiguration);
    }
}

After Changing the Language it look like this.

I have checked for missing translations. But all the strings are there . But not loading some of the strings. How to solve this issue

@YarikSOffice @RumataEstorish Last few months jitpack is continuing down for many hours. It would be more nice if you move your library to maven central https://github.com/jitpack/jitpack.io/issues/5239#issuecomment-1362481235

Hello,

I have Serbian language in the app. It can be "Latin" or "Cyrillic".
It's not possible to change this using this library.

For example to change letters to "Latin", you have to do this:
Lingver.getInstance().setLocale(context, new Locale.Builder().setLanguage("sr").setScript("Latn").build());

But it's not working as expected.
In this case this code is resetting the app language to default system language, English in my case.

This one is working fine when ".setScript("Latn")" is not being used:
Lingver.getInstance().setLocale(context, new Locale.Builder().setLanguage("sr").build());

Could you fix this bug please?

components of the app that use strings directly in xml eg the layouts correctly respond to language changes, however, Strings pulled by getString(R.string.xxx) remain to the system locale language

I was quite surprised when I realized that isFollowingSystemLocale is false by default. Let me explain my use case, maybe I'm missing something. I want my app locale to match system locale, unless the user specified otherwise explicitly in the app settings. So if the user just launches the app, then changes the system locale, I want the app to automatically change the locale to the system one. If the user then changes the app locale to a different one in settings, I want that locale to stick, so now system locale doesn't matter anymore.
If isFollowingSystemLocale was 'true' by default, everything would work naturally. I would use Lingver.setLocale() only when the user changes the locale in app settings. But since isFollowingSystemLocale is false by default, the first call to Lingver.init() on the first app run persists the locale, and subsequent system locale changes don't have any effect. So to achieve what I want, I need to call setFollowSystemLocale(true), but only on the first app run. Which is doable, but a bit annoying.

At the same time I realize that you probably can't change the default value now, because all apps with Lingver that didn't change followSystemLocale explicitly would start behaving differently.

And thank you for creating the library and publishing that blog post!

i add
maven { url 'https://jitpack.io' }

implementation "com.github.YarikSOffice:lingver:1.3.0"

but

Execution failed for task ':app:dataBindingMergeDependencyArtifactsDebug'.
> Could not resolve all files for configuration ':app:debugCompileClasspath'.
   > Could not find com.github.YarikSOffice:lingver:1.3.0.
     Required by:
         project :app

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

Library is working fine in debug build but after making the release build with dexguard library does not work.
I also keep the package in dexguard rules.
-keep class com.yariksoffice.lingver.** { *; }
But still not working

can you update the library, such that the App name in Notification gets updated when a locale is changed?

https://i.stack.imgur.com/qZKbq.png

I have notice that this library does not change the locale for all languages, for example Tagalog (iso code tl or tl-rPH in Android Studio) doesn't work.

Attached an example project to demonstrate the issue.
LocaleTest.zip

You'd get the following error if you use Robolectric for unit testing. The current workaround is to catch IllegalStateException.

java.lang.IllegalStateException: Already initialized
at com.yariksoffice.lingver.Lingver$Companion.init(Lingver.kt:192)
at com.yariksoffice.lingver.Lingver$Companion.init(Lingver.kt:182)
at com.yariksoffice.lingver.Lingver.init(Lingver.kt)

This happens because Robolectric calls Application#onCreate() on each test.

This Library in Khmer (Cambodia) Language not Working

When having single activity application (but it's not a must) and forcing locale change, when entering a fragment/activity with webview, the language is changed to the default .
This is the case described in stack overflow post - https://stackoverflow.com/questions/40398528/android-webview-language-changes-abruptly-on-android-7-0-and-above/40480347#40480347
It would be nice to add it to your project

How to check instance is initialized or not
like Lingver.getInstance().isInitialized

Steps to reproduce:

0. Have Android 9 (maybe 10 too)
1. Add languages in device. F.e. English and Russian
2. Switch device to Russian
3. Switch application to English.
4. Observe

Expected result:

1. App language is English
2. Actual result: app language is Russian (maybe partially)

Notes:
I think problem still is in "setLocaleForApi24".

EDIT 1:
further investigation lead me, that problem appears if I use language like "en_US", not just "en".

EDIT 2:
This case:

I am seeing some unexpected behavior even after calling
Lingver.getInstance().setLocale(this, language)
properly. The new language locale strings won`t show up unless app is exited and started again.
I guess it is related to the point mention in notes "Note that you need to update all already fetched locale-based data manually. Lingver is not responsible for that."
What exactly means by updating already fetched data manually and how to do it? What will be the best-practice for this ?

I'm investigating using Lingver from my project, but that would require it to be published somewhere other than jitpack. Would you be able to publish to either JCenter or Maven Central?

When app in release mode, aab file do not support arabic translation.
In app gradle I already have -
bundle { language { enableSplit = false } }
In proguard file, I have
-keep class com.yariksoffice.lingver.** { *; }

I am calling below method on Message Recieved(Push notification is received)
Lingver.getInstance().setLocale(this, Lingver.getInstance().getLanguage());

please suggest @YarikSOffice

Is there any advantage/disadvantage of initializing the library on a background thread?

I get this build error when I add the dependency:
More than one file was found with OS independent path 'META-INF/library_release.kotlin_module'

I'm using Android Studio 3.5.2 with Kotlin 1.3.50.

Firstly, thank you for the library.

While I debug on my computer everything is working fine, when I publish to Play Store, and I download from there, then, if the default language of the device is English, the library is not working. If the default language is Russian, everything is working fine.

Could you help to solve the issue?

Steps to reproduce:

• Create fragment
• Add menu to fragment
• Rotate device

If you add something like this:
override fun onPrepareOptionsMenu(menu: Menu) {
super.onPrepareOptionsMenu(menu)
menu.clear()
MenuInflater(activity?.applicationContext).let {
it.inflate(R.menu.main_menu, menu)
super.onPrepareOptionsMenu(menu)
}
}

it solves problem, but adds new one - app:showAsAction="always" is ignored

I've created fork to test this out and maybe add some fixes if have any, but no luck.
If you want sample, please check https://github.com/RumataEstorish/lingver/tree/fragment_menu_test

Hi! When I'm changing the app language to Arabic (from English) the app is struggling with re-drawing the layout to an RTL, even after calling activity.recreate(). It does well only when I close and open the app again. Same things happening when switching RTL -> LTR. Could you please give any suggestion, how could it be fixed? Thank you.

Both English (en) and Persian (fa) switching works properly but when I try to set language to Arabic, app displays default language strings and maked LTR, also when I get language value, it returns ar!

Sorry for my bad English :)

I have:

• activity A with option "Change Language", activity B opens after click on "Change Language"
• activity B with list of languages, language is changed after click on element of list by:

 val localeCode = languageList[index]
 Lingver.getInstance().setLocale(activity.application, localeCode)
 activity.finish()/*finish activity B*/

[result]: Activity A resumed, but locale was not changed

The same behaviour is implemented at Telegram app

Hello,

Thank you for the library and the blog post. It has been very useful to me.
This is more of a question more suitable in a discussion tab but I couldnt find a discussion tab so adding it here.

I have a question that I am curious about.
While checking android docs about handling in app language changes, they mentioned using androidx AppCompat's setApplicationLocales and getApplicationLocales which seems to have a consistent api accross different api levels, and also auto persists language changes using the autoStoreLocales.

I am wondering why the library does not utilize that and instead handle different api levels differently and manages its own storage.

Are there downsides to the appcompat approach and you think the manual way offers something better or do you think the appcompat's way is actually better but did not update the code cause why fix what is already working or you don't have the time for it.

Thank you very much and if anything I said doesnt seem right, please bear in mind I am a beginner android dev

The library works fine when I install it directly from Android Studio.

However, when I create signed app bundle, upload it to play store and download it from there it stops working. Language is always in system's locale. I'm not using proguard which should change the source code.
I own devices with API 29, 23, 21 and only 21 works correctly on play store's version.
Any idea how to fix this strange behavior?

Hello,

I was reviewing the code of the library and I noticed that it's using res.updateConfiguration() (deprecated in API 25) for all API versions, instead of using the approach described in the article.

This is not an issue with lingver but more like the followup that I've never figured out.
In light of

Note that you need to update all already fetched locale-based data manually. Lingver is not responsible for that.

I understand that Lingver's responsibility ends after updating the locale using
Lingver.getInstance().setLocale(this, language)

what I have is a button in a custom ActionBar, pressing that button calls the Lingver.getInstance().setLocale(this, language) and the ActionBar is used on every activity on the project, so that on any activity the user is able to change the language at any time by pressing that button.

the main issue is when there are activities and/or fragments that are already open in the backstack.

so what's the go-to approach? how can one change the data (e.g. TextView, RecyclerView, etc...) that are already fetched in activities and fragments that are on the backstack?

I've tried to override onConfigurationChanged inside my activity class and reset my views there
but it was never called even after adding android:configChanges="locale|layoutDirection" to the activity in the android manifest

I have also tried to call recreate() after using Lingver.getInstance().setLocale(this, language)
it does work as it resets the activity but it gave me literal hell for my viewpager and fragments configuration so I'm looking for potentially better alternatives.

Hi,

first of all thanks for your Lingver library project.

Is there a way or a "special language-key" that always returns the

defaultLocale: Locale = Locale.getDefault()

from the app-start?

Thanks and Regards

This is a great lib for localization. I saw a small point: there was no res/font folder in the sample project and this means the fonts that developers set separately for each locale are not be loaded on recreating the activity, they will only be loaded and set on starting the app again. So by changing the language on a hypothetical SettingsActivity and doing a recreate(), the specific fonts for new locale will not be loaded.
