Kotlin Multiplatfom app for Droidcon Events

Sessionize/Droidcon Mobile Clients

General Info

This project has a pair of native mobile applications backed by the Sessionize data api for use in events hosted by the Sessionize web application. These are specifically for Droidcon events, but can be forked and customized for anything run on Sessionize.

Building

The apps need a Firebase account set up to run. You'll need to get the google-services.json and put it in android/google-services.json for Android, and the GoogleService-Info.plist and put that in ios/Droidcon/Droidcon/GoogleService-Info.plist for iOS.

Compose UI for both!

We're running a very early version of Compose UI for iOS as the iOS interface. It mostly shares the screen code with the Android app. While Native Compose UI is obviously experimental, it works surprisingly well.

Fragment navigation transition

Add slide transition when going from schedule to session, and session to speaker. iOS is doing this now, if you need a model.

Add room to schedule view

Building sqldelight

Hello,
whilst building the android project, I get this error:

Could not resolve com.squareup.sqldelight:gradle-plugin:1.0.0-kn0.9.1-a2.
> Could not parse module metadata https://dl.bintray.com/touchlabpublic/kotlin/com/squareup/sqldelight/gradle-plugin/1.0.0-kn0.9.1-a2/gradle-plugin-1.0.0-kn0.9.1-a2.module
> Unsupported format version '0.3' specified in module metadata. This version of Gradle supports format version 0.4 only.

I ran the command ./gradlew generateSqlDelightInterface too.

Any ideas how to solve it?

Replace kotlinx.serialization

We have the source directly copied into the app code, but that was from quite a while ago.

Rsvp dot needs to move down a bit on time row

Add "my schedule" to android

Android currently shows the full schedule, but needs a "my schedule" view. Wire the params to the fragment and pass into the model data pipeline.

Schedule view doesn't retain selected tab when navigating back from detail view

When you select day 2 and navigate to a session, going back resets the selected tab. It looks like the tab control just "forgets" the current selection. Probably something in the fragment lifecycle.

Port speaker view

The layout and logic for the speaker view should be ported over. In the original app, we have a different endpoint to update speaker info, but it really doesn't change that often, so we can skip that. Just pull speaker info from the db and assume updates will be recent enough from global data load.

Unsupported format version '0.3' specified in module metadata

When I open the project in android studio 3.3 canary 6 with gradle version 3.3.0-alpha06, I am facing this error "Unsupported format version '0.3' specified in module metadata. This version of Gradle supports format version 0.4 only". The project doesn't sync and build.

Rsvp indicator doesn't always refresh after being clicked.

Sometimes when you click the rsvp fab it'll clear the icon but never show the new state

Add analytics events

The most important event is the rsvp event. We want to write whenever an rsvp is performed. Should write event (rsvp/unrsvp) and the session id. We'll use that data to gauge interest in sessions. Other events can be added later, but we're not super interested in actually tracking anything.

Unable to `./gradlew build`

When trying to runs with ./gradlew build (based on IOSDEV.md steps no. 5), the ktlint works as expected (failing if there's file violate the rules), due to a lot of file violated, I'm commenting the ktlint plugin, and re-run the ./gradlew build afterwards following error happened:

Only one Kotlin framework can be loaded currently

After running the app on Android, it works fine.

But on iOS, application crashes with following:
Only one Kotlin framework can be loaded currently.

Maybe it is because of two frameworks linked - main and lib.

It has also been reported here, but I'm curious if you have any solution:

Async way to getData from Firestore

Hi, first of all thank you for this library!

But I have a question, is there any way to get data from Firestore without callbacks? Are you thinking to develop it?

getFirebaseInstance()
                .collection("sponsors-sf-2019")
                .orderBy("displayOrder")
                .get_()
                .addListeners(...)

App routinely forgets "My Agenda"

I'm at Droidcon right now, and am trying to track my planned schedule in this app. I am using the "My Agenda" feature, and have marked sessions and workshops for all three days.

The app has forgotten my schedule twice already, and I have to find the sessions again, so I can add them to "My Agenda" again.

I do not know what causes this, but it could be related to internet connectivity problems. I am using this app on a phone without a SIM card (--> phone has no internet if it isn't connected to WiFi).

Phone: Samsung Galaxy A71, running Android 11 / OneUI 3.1 with the August 2021 security patch.

Add Sponsors view

This involves both the data download and the view copies. The views can all come from the existing droidcon app.

"Pass" on a session feedback

Should be a way to pass on specific feedback but not shut down "feedback".

Session Block Padding

On Android the lists have zero padding/margins and therefore the items all run together, making it hard to see relevant information at a glance.

Move event detail to a new activity

Currently EventFragment is opened in the MainActivity, but to make nav simpler, I think we should move this to a new activity. The app bar should show a back button, and there should be no bottom bar.

Port to new gradle plugin and KN 8.1

This is a broad change that will require dependency packaging changes as well. Should probably wait till after Droidcon

Update FirebaseMessageHandler

Some things were removed/deprecated.

Rename shared project from "notepad" to "sessionize"

The app originally came from the notepad sample we built for knarch.db. The name should be changed to sessionize, or whatever we ultimately name this. That rename includes a few tasks (see project).

Question: Is there any reason why the :sessionize:app module is in Multiplatform?

Just wondering why the sessionize module was configured as a Multiplatform Module. It seems to me that it could simply be a normal android application. Is there any special reason for this?

Add Ktor

Replace simple get with Ktor

Splash screen

Splash screen showing conference logo and basic "brought to you by" info. Needs design first.

Publish Droidcon App

not just repo, public too

Scroll position after rsvp click

Scroll sessions list, click into a session, click back. No problem. Click into a session, click rsvp, then back, and we lose position.

I suspects the database flow updating data, and that wipes the state.

Tested on ios

Move to Gradle 4.10.2

This will require republishing libraries

Can't find SQLiter dependency

Hi

I am trying to build and run the iOS app, and got two errors on running ./gradlew build. The first related to failure to find sessionize/app/release.jks, so I created that.

Following that was a failure to find co.touchlab.sqliter:sqliter:0.1.1-k1.3.0-a6, this could not be found in any of the repositories.

I assume this needs to succeed before I can build the iOS app in Xcode, because the Run Script phase there is looking for the folder sessionize/lib/build/xcode-frameworks.

Is there a missing repository for sqliter library?

Failed to build the iOS App with xcode

According to the build log, xcode with Version 10.1 (10B61) complains about "not found framework lib_umbrella".

Keep getting notifications

When I restart the phone, or turn internet on/off, not sure, but I've seen multiple notifications for all my talks come up days after the event. This happened about 3-4 times since 29 Oct.

Here's the last instance:

not able to resolve, co.touchlab.firebase.

CPU was spinning heavily on iOS

iOS app uses a lot of CPU at rest. Not sure if that's a Compose thing or not (experimental, so if so lets not worry about it...

)

Notification when session is starting soon

This has traditionally been difficult because you have to get the time zones correct and provide a way to enable/disable. If anybody wants to give it a shot, would love to have it. Just Android for now.

Failed to resolve: co.touchlab:firestore:0.2.1

Getting Failed to resolve: co.touchlab:firestore:0.2.1 error when I try to build latest code.

Support for Kotlin 1.3.41

Hey guys, this app is a great example of how a K/Mpp project can be structured and as such I guess that it's used by many people as a kind of a boilerplate project. And as such, it would be great if it could support Kotlin 1.3.41.

Make background task function with coroutines

We're almost there, but there's some issue with returning from background thread task. May not matter if multithreaded coroutines happen.

Include regular sqldelight

This won't matter until there's a release candidate, but we should replace the fork of sqldelight with the published version when it happens.

Apply style from zepplin design

The zepplin design has the basic layout for the schedule screen, as well as a style guide. Not sure of the best way to approach this, but ultimately I'd like the UI components to be from the material components library, and the style to be done in that context. I did the material components tutorial and it seems like we should be able to have a pretty minimal style definition.

Doesn’t remember scroll position in tabs when navigating

Assume this is when selecting different bottom nav, going back to the schedule resets all. Should probably implement a more standard nav control. Possibly try out the jetpack nav thing?

Add network pull

Currently we hard code the data into the app directly. We should also pull from the network on startup, and possibly at other points. Wire in the networking dependency and calls to handle this. Both platforms.

Add job to force refresh of schedule more often than app start (Android)

We refresh the schedule on app start, but it would make sense to create some type of timed job to do this later on as well. Say every day around 8am, and if morning of conference, every hour. Disable after conference.

Add analytics endpoints

Add firebase analytics clients to both Android and iOS clients, and have the actual method 'logEvent' write to them.

Prompt for feedback

Need some thoughts on what this would look like, then what to capture and where to put it. We do run a simple heroku web server that can probably accept data push, but if there are services or simpler back ends, would consider that. This will very likely not make it in for this year, but will do if we can.

Wire bottom nav

Bottom nav currently doesn't do anything. Should be wired to showing root level fragments.

About Screen

Create about screen. Can just have similar look from earlier apps.

Add crashlytics to Android

Answers is configured, and Crashlytics is working on iOS. Just need to finish on Android.

Droidcon London 2022 schedule

Hi people,

Do you plan to release 2022 schedule?

Kind Regards,
