app-thesis's Issues

Make adding notes even faster using third party services

Potential experimental feature:
E.g send requests to https://dictionaryapi.dev/ and process the result.
This way adding notes becomes even faster and increased quality of user experience.

Change language in settings

Add localization to app

Associate pronunciation with audio from filesystem

Ability to add audio files from device to flashcards. Currently recording their own voice is the only option

Add or delete doesn't have effect on flashcards

I've removed all the default flashcards and added new one but I'm still getting the old ones and none of the new flashcards.

I can see my newly added flash cards under manage FlashCards but and I don't see the deleted ones but as I said none of the new ones are shown in review.

F-Droid inclusion

We received an inclusion request over at F-Droid. To get this app into F-Droid multiple things need to be done.

First it would be nice to have the approval of the original author (which seems to be @uestueab here).

The other things are more technical nature:

• Releases should be tagged, so that F-Droid could know which specific code they need to build the app
• Please add Fastlane filestructure so that F-Droid build servers could get the metadata of your app directly from your repo, which drastically reduces maintenance effort for the F-Droid team
• Please upgrade you gradle wrapper, which should be as simple as ./gradlew wrapper --gradle-version 6.7.1 --gradle-distribution-sha256-sum 3239b5ed86c3838a37d983ac100573f64c1f3fd8e1eb6c89fa5f9529b5ec091d

choose location of cache data

for files like recorded pronunciation, let user choose the desired path.

Adjust frequency of notification

Let the user specify an interval for the notification frequency

Smart exit

In the add notes activity, don't exit immediately when there are populated fields. Make the this selectable from within settings

Recording animation

Currently: Shows Toast on bottom when recording/stopping.
Should be: Show animation on bottom to indicate recording. Stop animation when stop button is pressed.

Or: Implement hold to record feature. E.g. record pronunciation for the duration of holding the record button, and stop when releasing the press.

Remove synonyms with checkboxes

Currently: remove button deletes the last edittext field.
Should be: A checkbox next to edittext field to delete the selected synonyms

Permissions for API level30+
