GSOC proposal 2021
AnkiDroid is a free Android flashcards app which makes remembering things easy. It is a space repetition software for Android. Because it's a lot more efficient than traditional study methods, you can either greatly decrease your time spent studying, or greatly increase the amount you learn.
Anyone who needs to remember things in their daily life can benefit from Anki. Since it is content-agnostic and supports images, audio, videos and scientific markup (via LaTeX), the possibilities are endless.
For example:
- Learning a language
- Studying for medical and law exams
- Memorizing people's names and faces
- Brushing up on geography
- Mastering long poems
- Even practicing guitar chords!
We are proud to have 4.8 stars on the play store, and 2 million active installs (as of january 2021). It has an active community of developers, with 34 contributors to code in 2020, two new maintainers, and even new localizations. An important part of the contributors discovered android programming with AnkiDroid and we are always happy to help someone contribute, independently of Google Summer of Code.
You can reach us on Ankidroid’s forum, on the Anki's subreddit, or on the discord #dev-ankidroid.
This list of projects is not exhaustive. Discussion with the intern may lead to new projects. In particular, if the intern uses the app and wants some feature, we may consider helping them create those features. Not all projects have the same difficulty level. We will choose a project to work on first, and if the intern does the project quickly we’ll be happy to work on a second simple project.
(ticketed - but we can do much better here by moving it all in-app)
A deck is a set of questions and answers that you want to learn. For example, a list of all countries in the world or the 1,000 most used words in French. Currently, you need to download a deck first and then import it. So, in this feature, the idea is to allow users to download decks with deck download url, deck id, deck name etc. in order to browse, download, update and import that deck directly into AnkiDroid which improves user experiences.
Another potential feature to consider is to share decks directly from AnkiDroid and add it to the repositories of all shared decks. Currently, this can only be done from the website.

(PR) Questions and answers are displayed in WebView using HTML/CSS/JS. Buttons are already present to allow the user to do basic formatting such as italic, bold, adding images etc. That was found to be acceptable when the app was created ten years ago, when we expected most users to create questions using the computer. Nowadays, people have smartphones and don’t necessarily have the app on their computer, thus, allowing more advanced tools becomes more important. This project already started but is not yet fully functional. The intern would work on moving this project to production.

(ticketed - needs GUI) Currently, AnkiDroid allows only to import decks in the format .apkg, a format used only by Anki. While it is great to share a deck that already exists, it is not always ideal to create a new deck. As an example, let’s say that you want a deck to help you learn Chinese and your mother tongue is Persian. There may not already exist a Chinese-Persian deck. You may want to create a CSV file, that is, a text file which contains a list of words you want to learn, adding on each line “Chinese word, Persian word”. It is easy to create manually and also easy to generate automatically.
Currently, this feature exists only on the (free) computer version of the app.
The goal of this project is to add an option to import such a list of questions/answers in AnkiDroid. Option in AnkiDroid to import CSV or TSV files and add notes to database using those files

Currently, most of the documentations are created for users who want to learn with our app. However, there is a lack of centralized documentation toward developers and deck creators. Questions can have the full power of HTML/JavaScript, and use a template system that is highly parameterizable. More documentation of the advanced features, and of the concept behind the app, would be extremely appreciated.

Onboarding helps new users to introduce the app. The new users may need to understand the user interface of the app. The user may even don’t know about space repetition software. So, the idea is to tell about the advantages of using the app in learning and memorising things and how AnkiDroid will help in memorising things easier.

We list other ideas, we would be happy to discuss them with a potential intern if they find them more interesting, but expect that the above-listed projects should already give an idea of what kind of projects the intern may participate in.
We have various users on the Play Store suggesting that that application could improve both its UX and its UI
The app will receive less negative criticism about its user interface

Variable: Easy-Hard, depending on how large the scope of the change will be
This is vital to the project continuation
Google Play will enforce that apps target API 30 (Android 11) later on this year. After this date, we will not be able to release upgrades to AnkiDroid on the Google Play Store until we upgrade the app.
We currently run using the requestLegacyExternalStorage flag. Once we target API 30, this flag will no longer work on Android 11 devices.
For us to support this flag, I believe that we need to migrate to Scoped Storage: https://developer.android.com/about/versions/11/privacy/storage. The outcome of this will change how AnkiDroid's storage works, likely moving the publicly accessible AnkiDroid folder, which may mean changes to:
- Collection database
- Sync outputs (collection & media)
- Camera/Microphone Outputs
- "Save Whiteboard"
- AnkiDroid API usage
Mentors are less likely to know these new Storage APIs so this will involve collaboration and an aspect of experimentation and independent research.
Likely Hard
Google has introduced a new library for Preferences, we should move our Preferences and Deck Options screen to use this

Google has developed a UI/Application Exerciser Monkeyy which performs automated actions to test for bugs in an application. It would improve our testing process if this is included in GitHub actions.
Care must be taken to ensure that this does not cause actions affecting external services (for example: spamming AnkiWeb/our translations services with requests).
AnkiDroid has much more stronger testing suite, and there is less chance of a crash bug being seen by the public

- Donation drive from corporations rather than focusing on individuals (to discuss)
(ticketed - needs GUI + GUI design)
- Milestone notifications (encourage users to share/like/donate at given intervals. Need to discuss with others on the project as it's not in Anki Desktop and don't want it to be spammy)
- Press Pack/Support for Academics using Anki(Droid) for research
