As is too hard to build the project for checking, I think this is due to you didn't call Glide.clear(thumbnailImageView); in VideoStepFragment.onDestroyView(), as a result NPE occured.

You can reproduce this issue by fast swiping between video steps.

Hello I am interested in your project and would like to add it to Izzy repository. But There is one requirement I wish for.
Could you add the .apk file to your releases. He said it is needed so he could add it.

Hi. We've already translated Stepik's website into Belarusian. And now want to contribute translations for the Android app.

I'm not an Android developer though, so it would be nice to clarify some moments before diving in.

As far as I get, the workflow should be the following:

1. Create a fork
2. Translate strings in XML-files from \app\src\main\res\values-ru\
3. Place translated files into \app\src\main\res\values-be. Any other configs should be made?
4. Create a pull request into master-branch (or any other?)

Please check if everything is right. Thanks.

Hi Team

In the recent Play Store policy, it will become mandatory for you to fill out the Data Safety Section. Since this is an OSS Android app, it will make sense to have it as a part of the repository as well.

I have run the scan using my tool here on your repo, attached are
the scan results. I found the following:

• 7 data types
• 0 SDK.

If this is helpful, do use our free tool to generate Play Store Data Safety report: https://github.com/Privado-Inc/privado

Also, do share your feedback & thanks for the OSS app 😄

I chose TOEFL vocabulary and when I press play the audio does not start playing.

Hi,

Since this app is Apache v2 licensed, are you considering the fact to add it to F-Droid? There is a strong community behind, that do not use Google Play nor anything else, except F-Droid.

You can find some documentation here.

Otherwise, if you don't want to work on the inclusion of this app by yourself, would it be ok for you if someone else do it for you?

Is this a fully open-source app? If so, why "buildsystem\secret.gradle" cannot be read?

Столкнулся с проблемой - не могу собрать проект из-за файла buildsystem\secret.gradle
Судя по всему этот файл зашифрован.
Нужна инструкция как начать работать с этим файлом.

Can I contribute burmese translation to the app?

I tried to use stackoverflow solutions but it did not help

I want to start to contribute but the project gives this error. How to solve it?
