• Four separate databases are used to store lectures, meta, alarms, highlights (aka. favorites).
• Databases are accessed via custom classes extending SQLiteOpenHelper.
• SQL code fragments is spread throughout the applications.

Target state

• Encapsulate database within its own Android Studio module.
• Provide abstraction layer (repository) to access the database module.
• One database is used.
• Database is accessed via Room.

Hi,
in version 1.33.1, events with a yellow-ish background become hard to read, when added to favorites (white text on a bright yellow background).
Items in all other colors are easy to read.

See the attachment; I'm using a Nexus 5x.

During MRMCD17, I received multiple push notifications for any single schedule update. The first notification would display the correct changes. Every following notification would display "0 changes".

System:

• OS: Android 6.0
• Manufacturer / Model: LG G4 H815

When using the app in portrait orientation the swiping gesture to move to the next/previous room is very slow. This leads to usually swiping too fast and switching all the way to the first/last room.

System:
Nexus 5X
LineageOS 14.1, Android 7.1.2

Version:
1.33.0

Once you've chose the talks you want to attempt, it looks straight forward to be asked which talks you really attended.

Then, a common usage I noticed during the 34c3 is to spend time each of the last days of the event to download the talks you wanted to be in, but missed… So what about downloading All selected talks or All missed talks from the EventFahrplan app directly on your phone ? (to watch the talks later, for instance in the return train).

Currently, the favorites fragment can be added more then once to the backstack.

How to reproduce

1. Open favorites from the toolbar menu
2. Open any event details by clickling on an event
3. Open favorites from the overflow menu
4. Press back to pop the favorites and see the event details again
5. Press back again

Observed behavior

• Favorites are shown

Expected behavior

• Full schedule is shown, event details are closed

Play Services are not acceptable for all congress users

F-Droid doesn't allow arbitrary jar files in the source tree, because it needs to ensure that the source code for the entire app is available and free.

It seems that TraceDroid-1.1.jar is coming from https://github.com/ligi/tracedroid

Why don't you simply include it like this instead of using a jar?

dependencies {
    compile 'org.ligi:tracedroid:1.4'
}

Is it possible to get the F-Droid app in sync with the playstore app on android so it shows the small rooms as well?

Background

• Meet Google Play's target API level requirement

Target state

• targetSdkVersion 24
• Remove/replace deprecated code with new APIs.
• Probably update Notification implementation.
• Check app in split-screen mode.
• Replace android.net.conn.CONNECTIVITY_CHANGE in AndroidManifest.

During the congress, we are encouraged to rate the talks. Right now, this seems to only be possible via the link provided on https://events.ccc.de/, but not natively from inside the app.
Unfortunately, rating via the web site is pretty clunky and not optimized for mobile.
Would it be possible to add this feature?

Problem

Currently, some database columns such as for the "lectures" table define the data type "STRING". This is not a native SQLite data type. By the rules of column affinity this is mapped into the storage class "NUMERIC".

Error scenario

In the following scenario this behavior causes an error. Given there is a room named "008" and this information is stored in a database column typed as "STRING" the room name value becomes 8. When the schedule is updated the old and new room names are compared. Due to loosing the leading zeros this lecture is always marked as changed, falsely.

Recommended solutions

• For updates of existing apps the specific column types should be altered via database migrations.
• For new apps all column types defined as "STRING" should be changed to "TEXT".

• Android documentation on DeadSystemException

The status bar at the top of the detail screen shows the time, place and identifier of an event as show in the screenshot:

TODOs

• Add meaningful and clear icons for each element.
• Icons must be vector drawables, based on SVG.
• Define custom colors for ccc35c3 and cccamp2019 flavors.
• Test with long room names
• Test on device/emulator running Android 4.0 (API level 14) and Android 10 (API level 29).

AFAIK that is the first year when room status is available thought API at https://sojourner.loomchild.net/#/tracks

It would be grateful to incorporate it into the app somehow, so people could make more confident decisions attending the tracks.

Is there information available to update infos on past talks with links to https://media.ccc.de / chaosflix?

If so, the app would remain a very valuable tool after the last conference to rewatch favourites or discover more.

Hi,

the Fahrplan is updated quite often with many new Talks and Information about those. Unfortunately its hard to see these changes, because the "changelog" is showing all changes and not only the information for events running now or in the Future which would be more relevant.

It would be nice to have an option to remove past events from the "changelog"

• Issue #106: add option to show notification for changes in favorites only

At least for angels it was nice if there was an iCal export for the system calendar. Then you could add your shifts and favourite talks to the calendar an immediately see collisions. If you could subscribe to your favourites (in order to get updates) this was even better.

Hello there
In the overview, could you please change white on yellow to a more readable black on yellow or switch to a different BG color?
Not really good to read on OnePlus 5 and other bright screens.

• The following feature replaces the existing favorites feature of the app.

Implementation hints

• The implementation can be split into functionality (persistence, model, ..) and UI while the latter should be merged last.
• Further certain parts of the feature such as the tabbed list can be down separately once the basic functionality is implemented.

As a user I want to mark an event with different tags. The list of tags must be extendable.
A few predefined tags might be:

• "favorite" or "want to go"
• "watch later" when the recording of the event will be available
• "uninteresting"
• "attended"

Schedule view

• All events are shown
• Each event shows the tags as symbols
• Events tagged as uninteresting are less visible (the event with the thumb down icon)

Long-press

• By long-pressing an event a modal dialog appears where users can quickly assign tags or create a new one.
• Beside the tag actions there are the already existing actions. It might be helpful if the tags action are somehow grouped visually.

Event details

• The side pane shows event details and the tags

Tags

• The side pane shows all tags in a tab list and tagged the events

The actual behaviour is that the time is highlighted no matter which day is selected. That can lead to confusion and people sitting in the rooms on the wrong day.

Everytime I open the App, I see day one as default. That's not a good idea on day 2 and later.

Can you please detach this repo from the not maintained fork?

You can this either do it manually or – which I recommend – just contact the GitHub support to do it for you.

This…

1. shows that this is a real maintained project and not just a repo of someone who (once) made a pull request
2. linking to the original repo on every page does not make sense anymore as it has been discontinued/is not maintained anymore and you…
3. can (and IMHO should) still link to the original repo/website/author/… for crediting them, but you can do so in better ways (in the Readme, wiki or so)
4. allows searching in this repo on GitHub and
5. it just looks much nicer

see subject.

Day 2 of 34c3. 0:10 28.12

The current time highlighted is at the end of day 2 instead of the start

Actually it should highlight at the end of day 1

Hints

• The original schedule data of the 34C3 event can be requested from @johnjohndoe to analyze this issue.

Related

• Issue #105: Current time marker
• Issue #167: Time column not shown

The favorites screen has a lot of white space as indicated in the following screenshot:

The whitespace happens to be there when no text for the abstract has been provided.
Remove unneeded white space.

Given the app tries to fetch the schedule and the server is not reachable. Then it is not possible to cancel the fetch process.

User report

It crashed when I was switching back to the app from another app. AFAIR a talk's page was open before, not the schedule view. AFAIR I hadn't opened it for some time (>1h?). Wifi was off, used mobile data.
Switching back and forth didn't provoke it again. Has run stable since.

Related issues

• Issue #18 appears to be related.

It is 22:35, day 3 and I am browsing the talks on day 3. When I switch to day 1, the time line on the left side ends at 19:15. All the talks are displayed but after 19:15 no time.
It does not matter if I switch from day 2 or day 4 to day 1, the problem always occurs on day 1. No other day seems to have this problem. Landscape/Portrait makes no difference.

• App version 1.33.3
• Samsung T320 Tablet
• Android 4.4.2

I would like the app to select the current day by default. At the moment the app opens alsways with day one selected.

It is really beneficial for the normal user workflow to stay at the current scroll position.

At the moment, the app always scrolls back to the current time and the user has to scroll all the way down again.

Many users go through the schedule and try to decide which lectures/talks to go to.

Enviroment

• Device vendor: Lenovo/ZUK
• Device model: ZUK Z1 (Smartphone)
• Android version: 5.1.1
• Cyanogen version: 12.1-YOG4PAS9IG

1. Start the app, navigate to the main view (if necessary)
2. Scroll up or down and tap on a talk to see it's details.
3. Tap the back-button.
4. You are now at the current time again, not where you initially scrolled to.

The tablet mode (splitted with calendar + event view) could be great also on smartphone.
A settings togglebutton could force the mode.

On my Android device (7+) I cannot see any room except the 4 main halls.

Downloaded the App yesterday from the Playstore.

I Love the Sharing Feature, but it's a very long Text If you Share it over Smartphone Messenger. Can you add an option for sharing without the Links to the events and/or make less whitespace between the events?

The different views (details, favorites, changes*) are scrollable but do not show scrollbars when users scroll. The alarms screen shows scrollbars.

*not verified yet.

Today (day 1) I was browsing through the talks on the first day. The current time is marked on the left side, but after midnight it disappears. When I switch to day 2, I see the current time is marked there.

Current status

• An event can be described by the authors via two sections of text: abstract and description.
• In some cases authors simply write on text and copy parts or the whole texts into the other section.
• This causes that the same text shows up twice in the app. As a user I don't want to read the same text twice.

Target status

• Identical text paragraphs in the abstract and description texts are identified.
• The abstract text is removed if it matches the description text.

Is it possible to integrate Self organized Sesions?
Thanks for your effort.

Improve readability by using white textcolour for "dark" backgrounds.

See https://en.wikipedia.org/w/index.php?title=Web_colors&oldid=651498112#X11_color_names (*) for a nice overview (when to use black, when to use white textcolour).

(*) newer versions of this page do unfortunately not visualize the contrast differences.

See here for something different: random generation of "nice" colours:
