| Posted: 23 May 2022 11:36 PM PDT Hi everyone! So I've been reading and trying to understand about UseCase in android and I'm beginning to get the idea of its usefulness. However one thing keeps bugging me. Imagine if a ViewModel needs to perform Create, Read, Update, and Delete operations and these operations are encapsulated within their respective usecases. Does this mean the ViewModel would need all 4 createUseCase, updateUseCase, readUseCase, and deleteUseCase passed to the constructor of the view model. Why can't I just use a single repository class that contains all these CRUD functions and still maintain "clean architecture"? Most online articles I've read use maximum of 2 usecases within the constructor of the view model for the sake of brevity, but none have talked about when a ViewModel needs a bunch of usecases to duly perform their functions [link] [comments] | ||

| Posted: 23 May 2022 03:47 AM PDT Hello all! I have created a simple android application that shows how to share instances between application, activities, and fragments. If you wonder how components - modules are managed in some special-simple cases(Subcomponents, Provider Interfaces, etc.) in Vanilla Dagger, you can get insight from the codebase. All the commit descriptions contain the case and the implementation details. I tried to keep the application as simple as possible to highlight dagger usage. Any feedback will be appreciated.

| I am building an MVVM project and I am getting this Runtime Exception. Posted: 23 May 2022 10:14 PM PDT java.lang.RuntimeException: Unable to instantiate application com.example.cryptofinaltest.NotesApplication package com.example.cryptofinaltest: java.lang.ClassNotFoundException: Didn't find class "com.example.cryptofinaltest.NotesApplication" on path: DexPathList[[zip file "/data/app/~~8oktCt4HIuTEMZiEBv1i1g==/com.example.cryptofinaltest-9D7IWH6gUFsApYfmQk21ew==/base.apk"],nativeLibraryDirectories=[/data/app/~~8oktCt4HIuTEMZiEBv1i1g==/com.example.cryptofinaltest-9D7IWH6gUFsApYfmQk21ew==/lib/x86_64, /system/lib64, /system_ext/lib64]] The debug text is this https://pastebin.com/gCe5DAxK please help...

| Custom extension to include existing ones Posted: 23 May 2022 09:20 PM PDT Is it possible for a custom extension to act as if multiple existing ones? For example with compose previews I always copy paste the same list of '@Preview' for light/dark mode, rtl layout, big font etc. Is it possible to create @CustomPreview which could replace all of them?

| Posted: 23 May 2022 07:54 PM PDT I _know_ I did a codelab where I implemented a navigation drawer, I just cant find it. If anyone has done the codelabs in this course, and knows where I can find it please let me know. https://developer.android.com/courses/android-basics-kotlin/course?utm_source=gDigital&utm_medium=website&utm_campaign=gwgsite [link] [comments] | ||
| Best Practices: Are we building apps for everyone? Posted: 23 May 2022 09:15 AM PDT According to Google, over 1 billion people live with some form of disability.
Start adding the contentDescription for all the user interface elements as common practice. if the image is decorative and does not add any relevant information, it's not necessary to add a description, and we can set the contentDescription attribute to null. Another option is to hide it from screen readers altogether using the importantForAccessibility attribute. This way, the image will not receive focus and will be ignored by TalkBack.

| Posted: 23 May 2022 09:11 AM PDT Hey Guys, I am a web dev and want to learn Android Dev as well and I was confused about the app flow of an android app. Let's suppose I build my backend using NodeJS/Express and I use my Android app as front-end, What is the "Middle Man" between the View and the data that is sent from the back-end? Backend - "Middle Man" - Activity Please help me out. If this sounds confusing just let me know. [link] [comments] | ||

| Single source file native app (without native_app_glue) Posted: 23 May 2022 06:18 AM PDT Simple example of a native app without Java/Kotlin, resources, glue code, Loopers, unnecessary synchronisation, standard UI, etc. https://github.com/jbendtsen/stuff/blob/master/android-colors.c Could be useful as a starting point for writing low-level cross-platform apps with visual parity.

| Published beta watch face and have an issue Posted: 23 May 2022 04:49 AM PDT Hi everyone. After a few years designing watch faces for Tizen I moved to wear OS and have an issue. I rolled out a beta version for a new watch face. The watch face is not available under my dev page within the store, even when I filter by watches ( Device). If I follow the link available in Play console it takes me to the watch face page but says "Your device is not supported". Searching the watch face at the store doesn't show any results. It is not the first time I roll out an app to the play store ( But first watch face). Did I miss something? Thank you. [link] [comments] | ||

| An open standard to replace GMS? Posted: 23 May 2022 03:57 AM PDT I'm sure I can't be the first to think of this, so is there an OSS replacement for GMS in the works already? I had the idea because I've been using the P40 Pro for over a year now, and there are a surprising amount of apps that require GMS. And some are not just convenient but actually quite necessary for my commute f.e. Yeah, there are workarounds like GSpace or running a container like VPhoneGaGa. But those are slow to start, cumbersome and I ask myself more and more, WHY do we even need this? [link] [comments] | ||
| Survey about app marketing services Posted: 23 May 2022 12:36 AM PDT Hi Everyone, I am Ravi. My team and I are conducting a small survey to get an idea about different Mobile App Marketing services taken by different App Developers, Publishers, and Owners or services provided by various App Marketing Agencies. It is also to see whether they are satisfied with App Marketing agencies' services or not. Kindly fill out this short form. It will just take 30 seconds. PS: Even if you have not conducted any such activities, please fill out the form. It will help us to know about the trends in the market. [link] [comments] | ||
| About Jetpack Navigation Component Posted: 22 May 2022 08:39 PM PDT So google encourage the devs to use Single Activity Architecture when making an application that uses Navigation Component, but I'm not too familiar with it and wonder I think it will be so much pain if we're using Single Activity Architecture like hiding certain views when moving between Fragments (ex: Hide Bottom Navigation View that bound to an activity), no onActivityResult-like function. But it also has its advantages like easy data sharing between fragments by using ViewModel, safe args etc. So I'm a bit confused would you recommend other devs to use Jetpack Navigation Component and Single Activity Architecture when building a new project?

| How do you guys handle credentials provided to Google for app review? Posted: 22 May 2022 11:55 PM PDT So i have added test user credentials to the play console as my app uses google login and the reviewer asked me to provide login credentials. But can I do anything about the fact that the reviewer might be unable to login to the app using his device as google might say its an untrusted device. Any thoughts on this? [link] [comments] | ||
| what are the best solutions to rebuild/remake an old app made with old Java? Posted: 23 May 2022 05:34 AM PDT So at my new job they gave me a really old app.. I was supposed to optimize it.. but the code is in Java an lots of libraries used are deprecated.. the android api target is level 27. Any advice or insight is the most welcome [link] [comments] | ||
