Follower - background movement tracker with OpenStreetMap (osmdroid) used for observing tracks

follower's Issues

Empty state in TrackListFragment

Add layer responsible for mapping empty state (no items at all) in TrackListFragment and proper handling changing of this state on adding new one and deleting the last one.

NPE while no import file selected and back tapped

Steps to reproduce:

1. Go to TrackList screen
2. Tap "import" button
3. Click back
4. Observe NPE

In Low Battery Notification mechanism fix Notifier to be audiable

For now at least on some phones sound is not playing during notifications

Move Low Battery notification feature to separate module

Move mechanism responsible for notifiying of low battery state to separate module. Add documentation (including high-level article). Add tests, including E2E tests.

Custom attributes of dependency's dependency creates problems with application's compilation

Dependency Loggy uses ExpandableLayout dependency to render error logs in dashboard. ExpandableLayout have custom attributes declared, such as el_duration and el_expanded. If application doesn't have ExpandableLayout dependency (doesn't matter is it used in exact application itself or not), project won't copile:
ERROR:/home/user/.gradle/caches/transforms-2/files-2.1/e7492b61a/loggy_sdk-debug/res/layout/item_error_log.xml:57: AAPT: error: attribute el_duration (aka dev.liinahamari.follower:el_duration) not found.
The only workaround found for this moment is duplicate dependency in application itself too.

Current track shown when tracking is on

When tracking is on, current track is showing for a moment in TrackListFragment. By design current track always hidden until it will be saved. Investigate why.

Feature: apply gradual way of fetching local data from Database while displaying to a User

In LogsFragment and TrackListFragment here's a lists of items to be displayed to a User. For a moment, before showing it to a User, we fetch all the data containing in the database. For better UX it's needed to fetch data step-by-step. Paging3 should help.

Opening JSON file representing Track from the outside of application

Should be possible to open file representing track via Follower application itself (not only importing from the application). Consider own file extension to be declared.

Feature: first-meet intro describing app's features

When user opens up application first time he\she should see slideshow describing app's core features.
Every slide should contain title, description, picture (representing device screen with specific application state) and some unique (comparing to other slides) background color.
User should be able to skip intro.
Title and description should be translated to app's provided languages.
This functionality, definitely, should be implemented via AppIntro library.
Some UI tests should be added.
TODO: Think about "splash screen" proxy with as fast as possible screen drawing mechanism.

Track Tags

User should be able to add tag to distinct groups of tracks.
TODO: think about redesign TrackListFragment accordingly tag functionality.

Improvement: automatic cache purging politics

Investigation is needed: which practices used to use open-source application to deal with increasing cache amount? Maybe some automatic time-to-time cache purging mechanisms should be presented.

Feature: backups & track sharing

• explore Storage Access Framework functionality and file access of it in particular;
• investigate .gpx file format of OpenStreetMap, it's impact and tracks' sharing guidelines;
• provide to end user options of creating, saving, updating, deleting and sharing* tracks;
• test saved in the App tracks in other applications supporting .gpx files (such as OsmAnd).

* sharing of traces is optional for now, the separate ticket is needed on demand.

Feature: cache delete

Investigate which possibilities exist to clear app's cache and provide section in settings which clears all the cache (or split different type of cache delete between multiple sections).

Migrate from kotlinx.synthetic to ViewBinding

Kotlin Android Extensions is deprecated, which means that using Kotlin synthetics for view binding is no longer supported. If your app uses Kotlin synthetics for view binding, use this guide to migrate to Jetpack view binding.

In Low Battery Notification mechanism consider replacing AlarmManager with Worker

To achieve lack of notifications in case device charging.

Database encryption

Database encryption in case of storing Tracks should be presented. Write documentation with test cases presented as well.

Intro screen's refactoring

Improve code base accordingly to AppIntro library guidelines.

• IntroActivity shouldn't be first one in the list of activities in AndroidManifest.xml
• AppIntroFragment is better in our case to use insted of self-written Slide fragments.
• Screen configuration should be added.

Feature: bunch delete tracks in TrackListFragment

Find out nice way to select multiple items in Track list to perform deleting. Possibly, swipe to left, because long clicks reserved for cascade menu.

Make low battery notifications' setup configurable by end-user

Add:

• possibility to turn off notifications at all
• respect\ignore DND mode
• possibility for notification to be silent
• possibility to change notification's timeout

Make splash screen smooth

Right now due to usage IntroActivity and RouteActivity there's a flickering white on application launch. There's a possibility to make UX more smooth using application themes.

Setting up ACRA-server

Don't forget to create map file for stacktraces and check it's working.

Fix issue which definitely related to in-app language enforcement

Feature: auto-uploading tracks \ observing FTP server's content

For a moment there's a possibility to upload JSON file containing some Track to FTP server manually. This operation should be performed also it tracking mode too.
Also, on a "client" there should be a possibility to observe FTP server's content in "real time" or by request.
Write documentation.

Map rendering problem

Investigate possible workarounds to deal with fuzzy map view using osmdroid library.

Singleton class PreferenceRepository

All the operations with SharedPreferences should be presented in one @Singleton class.

PIN support

For a moment app has Fingerprint protection of Tracks to being showed (impossible to perform such operations such as deleting, if on). For various reasons Fingerprint API might not be available, so PIN support should be presented.

Implement track distance

Track distance should be displayed for every Track element in TrackListFragment's list.

Paging for AddressTraceFragment's data

Implement paging for data exposed in AddressTraceFragment via Paging3 library.

Update WorkManager dependency to 2.7.1

WorkManager's API change, research is needed.

Long cold start on some phones

Investigate and profile long MainActivity initialization.
