| Posted: 27 Nov 2021 12:44 PM PST I've been working with compose on a new project for the past half year now, and I mostly like it. The learning curve is minimal and I quite like the declarative approach to building UI. I'm working with a small team and one thing I'm having a problem with is how to organise the code, with the traditional way the XML views were quite heavily coupled with the associated Fragment/Activity it was usually quite easy to run the app, look at what was on the screen and then find the corresponding piece of UI/code in the app. But with compose, the UI code can literally be fucking anywhere, the deadlines for this project have been tight also so we've been sloppy with things like code review and we've not really had any conversations about UI architecture with the new compose approach and so I'm coming to the conclusion that it is much easier to write complete spaghetti with compose, and when several different people are throwing their spaghetti into the mix it can make for a not so fun time when diving into the UI. So if there was going to be a question here it would be, is there anything out there regarding architecture when using compose? How best should composable functions be organised?

| Posted: 27 Nov 2021 09:34 AM PST I have an activity which contains a fragment to show feeds in list and there is a tab layout, having two tabs in this fragment and they show different list, and when there is no data for the selected tab ,error image with some text show on the screen.So,what would be a better approach here using two different fragment or just changing the adapter according to the tab selected?

| Telemetry library for Android suggestions Posted: 27 Nov 2021 10:39 AM PST I'm writing an Android app that will interact with a backend API I'm hosting on a cloud provider. I'd like to understand how users use my app, so I'd like to build in telemetry that tells me what the user did when and have that uploaded to my API periodically. Are there any prebuild solutions that do this, or get most (or even part) of the way there? OpenTelemetry seems to be designed to solve this, but I've been clicking on links there and it just goes deeper and deeper into marketing buzzwords and I have yet to see actual concrete implementations.

| Encrypting user data in-transit for User Messaging Platform SDK for Android Posted: 26 Nov 2021 11:43 PM PST Does User Messaging Platform SDK for Android encrypts user data in transit ? Data safety form in Play Console asks if all of the user data collected by your(my) app encrypted in transit. Information here does not explain how user data were transfered: https://developers.google.com/admob/ump/android/quick-start [link] [comments] | ||
| Posted: 27 Nov 2021 04:52 AM PST I was implementing a side drawer in my app, the problem is that I have to swipe from the far left of the screen to open the drawer. Is there any way to set a larger margin to swipe on? [link] [comments] | ||
| Is a dedicated GPU relevant for emulator performance? Posted: 27 Nov 2021 06:36 AM PST Hello fellow devs, I'm currently collecting requirements for a new work laptop and I was wondering if I would need a dedicated GPU at all. The only thing I could think of was running the emulator for Android development, which is what I currently spend most of my working hours on. I usually never used the emulator on laptops and preferred my desktop at home, as the performance was too bad to get anything done. My former laptops had ok specs and did well for other dev tasks but never had a dedicated GPU, which is why I'm wondering. Does anyone know more about this or has good reading suggestions? Thanks in advance! [link] [comments] | ||
| Typical use of inline functions in Android apps? Posted: 26 Nov 2021 02:45 PM PST Hi :) Can you share where do you use inline fun() in your projects? What is best practice to use them? Any thoughts on inline functions will be appreciated. [link] [comments] | ||

| Is it a good practice to cache AlertDialogs and AlertDialog.Builders? Posted: 26 Nov 2021 10:31 AM PST I was thinking whether creating new dialogs and dialog builders are actually heavy tasks to perform or not and whether caching them is going to be helpful or not because caching itself needs memory and finding the proper dialog to use later on needs iteration over cached dialogs. What do you think? [link] [comments] | ||
| Kaspresso 1.4.0: Jetpack Compose support (early access) Posted: 26 Nov 2021 03:28 AM PST Kaspresso now officially supports Jetpack Compose (early access)! Protection from flakiness, waiting for elements to appear, logging, convenient DSL, etc. Everything as you like =) Your test may look like below: ```kotlin class ComposeSimpleFlakyTest : TestCase( kaspressoBuilder = Kaspresso.Builder.withComposeSupport() ) { } ``` Read additional information here.

| Share your experience on handling API request errors :) Posted: 26 Nov 2021 02:41 PM PST Hi Android devs! Stack: Retrofit, Okhttp, RxJava2 Imagine next: You have request to get list of cars objects, you have typical code: disposable.add(apiService .getListOfCars() .subscribe(cars -> { // Success response }, throwable -> { // Error response // Handle error // Check for error cause? }) ); Questions: 1. In your apps do you check for error type, like HttpError, IOException, etc? 2. Do you post every error in onError() to Crashlytics as logException()? (we do and thus we have many non fatal errors like "Dns.class" which means user just had no connection) 3. Do you implement smth like RxJava Error CallAdapter? 4. Any best practice on this topic? Thanks! [link] [comments] | ||

| Posted: 26 Nov 2021 07:25 AM PST This is kind of an open question and a pretty long one. First a quick TL;DR:
I want to able to: * create multiple files in a directory of my or user's choice * "pre-selecting" one of those files for user, by storing its uri/path and displaying its name and/or path to user * have file's location easily accesible to user, by either: - showing him meaningful path to currently selected file - showing only file's name, but showing file's location immediately, when user tries to select another file (done with use of Intent with ACTION_OPEN_DOCUMENT action and DocumentsContract.EXTRA_INITIAL_URI extra) * preferably use Intent with ACTION_OPEN_DOCUMENT_TREE for selecting those files, to have system default's DocumentsProvider (file browser) be used, instead of implementing some custom file browser.
For whatever reason I am unable to find a solution fulfilling all above requirements. Full description
In my app in one of the settings, user has an option to provide custom configuration file instead of using default settings. To make things easier, a few example configuration files are created when he chooses this option for the first time and one of them is selected as a default. At this moment user should see on the settings screen which file is selected and should be able to easily find it in phone's storage, in case he wants to "play" with it. User is also able to select another file to be used in app (done by Intent with ACTION_OPEN_DOCUMENT action).
For some reason, this pretty simple scenario seems to be almost impossible to achieve with SAF or generally on apps targeting Android 11+. Why? First let's list requirements of above scenario: 1. App has to create multiple files at once. 2. User should be able to easily navigate to the generated files location on his own, so he needs to know where are they stored. 3. App's behavior shouldn't depend on whether currently selected file was selected by the user, or was selected by default when files were created - it should display similar info and show similar location, when choosing to select another file.
I tried multiple approaches and each of them either has a major drawback or simply is unable to fulfill one of above points. Below I list all of them:
First problematic approach - creating files with use of ContentResolver
This solution for creating multiple files in Android 11+ I found on StackOverflow.
It seems to be nice and clean, allowing as to create files in system directories like Documents. Sounds good. What is the problem? This creation method returns Uri in format of: content://media/external/file/123 We can get file's name from this Uri, but not its location. I hoped at least when selecting a new file user could be first shown location of the currently selected one (this way learning its location) with use of DocumentsContract.EXTRA_INITIAL_URI for ACTION_OPEN_DOCUMENT action Intent, but unfortunately it is not working for Uri generated this way. So 3) is not satisfied.
Sum up: Problem with finding the custom files by the user.
Second problematic approach - creating files in getExternalFilesDir() directory
Method Context.getExternalFilesDir() returns path to our app's folder, in which we can create files directly without problems and any permissions.
Problems: 1. Path to app's directory is long and difficult to read. Uri's path for a file (Uri.fromFile(file) ) created there would look like below: /storage/emulated/0/Android/data/my.app.package.name.is.long/files/customFile.txt Even with /storage/emulated/0/ part somehow removed, we are left with long and incoveniant path. Also user has to find our folder among tens of other apps' folders.
Sum up: I feel it might be confusing for less tech savvy users.
Third problematic approach - let user choose folder in which files are create, using Intent.ACTION_OPEN_DOCUMENT_TREE
It is a nice approach, because we get Uri to a directory in which we will be able to create all the files we need and Uri's to those files will allow for usage of DocumentsContract.EXTRA_INITIAL_URI when selecting new custom file. Meaning, the user will have easy way of locating currently selected file (including the default one selected in beginning) and we won't have to deal with all different kind of paths, just showing file's name without a path.
Problem: When using Intent.ACTION_OPEN_DOCUMENT_TREE, user is shown information that the app will have full access to all files currently stored in selected location, which might be scary. Especially, that when using this Intent the DocumentsProvider will usually open in phone's main directory... It would be better to provide some starting folder at this point, like Documents/MyAppName, but it requires Uri to pass to Intent using DocumentsContract.EXTRA_INITIAL_URI and I don't see a way of getting such Uri for a newly created folder.
Sum up: might scare the user away. Also requires couple extra actions from user, like creating new folder, clicking through "On the next screen choose location in which custom files will be generated" information, etc., etc.
Not suitable approach - using Intent with ACTION_CREATE_DOCUMENT action to create custom files
That would be perfect solution, but it allows creation of a single file at a time, in effect requiring multiple "save as" processes for multiple custom files.
I spent larger part of this week working on this problem, searching for different approaches, workarounds, dirty hacks and I couldn't find anything. Anyone experienced similar problem and/or knows solution for it? [link] [comments] | ||
| Is Google committed to AR on Android? Posted: 26 Nov 2021 01:06 PM PST I'm an iOS developer trying to understand Android's version of AR and I'm a bit puzzled. With AR you have sensing - ARCore/ARKit and rendering - ?/RealityKit (AR specific rendering). Android's version of SceneKit (general rendering) seems to have been Sceneform which they have deprecated without providing a replacement and are telling users to use OpenGL or Unity. Have Google lost interest in AR or are they working on something? [link] [comments] | ||
| Directing to web payment via a landing page Posted: 26 Nov 2021 12:14 AM PST Our mobile app also has its Windows and Mac version. So, in order to promote the cross-platform feature we created a web payment system that allows access on mobile & desktop simultaneously upon purchase. We created an explanatory landing page on the website, which also contains a CTA button directing to the web payment. If I send a push notification of the link to that landing page, is it against the policy? Would I be in trouble? [link] [comments] | ||
| Porting a Linux CLI program to Android. What will the process entail? Posted: 26 Nov 2021 09:41 AM PST There was an app in Linux called MIDIComp, it allowed me to convert MIDI files into readable text. I'd like to port over MIDIComp to be able to used by an Android app. What needs to happen to make this a possibility? Thanks guys [link] [comments] | ||
| Posted: 26 Nov 2021 01:17 PM PST I'm building a chat platform, where I'm reading my list of messages from Local Room DB (ChatModel). I need to add date separators between these messages. I've to use multiple view holders and thus created a sealed class for differentiating items I require to convert the list with date separate items in between 2 models of the list, I'm not proficient with Collection functions in kotlin and confused between map/flatmap etc. [link] [comments] | ||
| Help to select software for app development Posted: 26 Nov 2021 06:24 AM PST Hello all, I want to develop an app for personal use but have little experience in programming, only know Matlab and some Python. Can you guys help me select an appropriate program to start in? The app will be mainly about inputting questions and answers that then later can be used to learn a language. For example, input a list of words with translation which you can then practice. You can only go to the next word if you get the right answer. I see there are a lot of no-code/minimal code programs but I have no idea where to start. I am willing to pay around 10 euros a month after a free trial. Thank you in advance. [link] [comments] | ||
| The Device and Network Abuse policy, section 4.8 and 4.9 of the Developer Distribution Agreement Posted: 26 Nov 2021 05:12 AM PST Hi guys, The Play Store has recently introduced a new item in it's policies:https://support.google.com/googleplay/android-developer/answer/9888379#zippy=%2Cexamples-of-common-violations Stating as an example:"Game cheating apps that affect the gameplay of other apps." I find this not very clear in how the gameplay is affected or what "affect the gameplay" of other apps means. For example,
In my opinion 2. sounds legit while the other don't directly "affect the gameplay" of other apps. What do you think ? [link] [comments] | ||
| Which Google Play distribution tracks can I access before review? Posted: 26 Nov 2021 02:46 AM PST Hey folks, Right now our app is unreviewed and distributed through Internal Testing. We would like to continue using this for ourselves (people in the team). However, we would like to open up a new Closed Testing track (Alpha) and only accept users who are in a defined list. My question is: given that our app hasn't been reviewed by Google yet, will we have access to the Closed Testing feature? What else is blocked, besides production? Also, I'm not familiar with the review process. What does it take for an app to be rejected? Can we submit for review when the app is still missing plenty of features? Thanks! [link] [comments] |
