    Google Play Console issue: An unexpected error has occurred. Please try again. (4A3C9E78)

    Posted: 14 Jan 2021 07:26 AM PST

    Hello everyone, I'm trying to submit an app today and I keep getting this issue every time i press "Review Release". No matter if is for production, testing or whatever.

    An unexpected error has occurred. Please try again. (4A3C9E78) <--- this code changes every time.

    Did any of you try and submit a new app or update today? I'm losing it after 2 hours. Tried different browsers, incognito mode, apk instead of app bundle, nothing solves it.

    The best way to integrate WebRTC into an Android Application?

    Posted: 14 Jan 2021 12:00 AM PST

    Since Google's discontinuation of distribution of precompiled SDK of WebRTC (as described in this article), I've been looking into including the SDK directly in my application instead.

    The article states:

    Plan and aim for 2-4 upgrades a year of your libwebrtc SDK in your mobile application. Any less and you're in danger of breaking interoperability with Chrome or at the very least missing out on optimizations, improvements and new features

    However, the production/distribution cycle of the application does not allow for periodic updates as suggested in the quote. What I'm worried about is specifically the mention of "breaking interoperability with Chrome" - which means that either:

    1. Certain fundamental elements from the chromium framework already present on the device are being used, meaning that if the device's chromium gets updated, the WebRTC SDK used in my application might seize to work properly
    2. The chromium used by the WebRTC SDK is distributed inside of the SDK itself separately and therefore changes to the device's components will not affect the functionality

    A clue I might have found in this article states that:

    The checkout size is large due the use of the Chromium build toolchain and many dependencies

    Which to me sounds as if the second answer to my question is the correct one.

    I am inclined as to whether anyone has some experience with how these SDKs work and what course of action should I take going forward.

    All my competition is offering rewards in exchange for reviews in their apps

    Posted: 14 Jan 2021 06:11 AM PST

    Hello,

    I have noticed that most of the apps that are the competition of my app are getting reviews by offering rewards and unlocks in exchange within the app.

    Is this allowed? If not, how can I report it?

    It's hard to compete against this :(

    My team doesn't agree on to use DataBinding or not. So we decide for it, it's up to dev to choose. How about your team?

    Posted: 14 Jan 2021 06:18 AM PST

    As the title, my Android team has a long discussion about DataBinding.

    - I prefer keep using ViewBinding for its simplicity, build speed. Although DataBinding is powerful, but write logic inside XML is not my favorite code style. I choose write Java/Kotlin code to update code manually.

    - Other guy loves Data Binding because it is powerful & helps us to write less code.

    We cannot convince each others, thus finally let the devs in team free to choose any approach they likes, and will review it next quarter.

    I wonder in your team, do you force to use DataBinding, or let devs free to choose whatever they like?

    What happened to the 'Early Access' section Play Store App?

    Posted: 13 Jan 2021 11:33 PM PST

    In my Play Store app, under Apps, there was a tab called 'Early Access' along with other tabs like 'Top charts', 'Family' etc. But it is no longer there. Does anyone have an idea on why it is gone?

    Why does Signal use Java and not Kotlin for it's android mobile app?

    Posted: 14 Jan 2021 02:59 AM PST

    I've been reading a lot of good things about Kotlin for native android development and how developers prefer it over Java so I have to ask. Is there a security reason as to why Signal uses Java, or is it just preference?

    OnboardingSupportFrament vs. Custom onboarding

    Posted: 14 Jan 2021 04:45 AM PST

    I am currently working on adding an onboarding message to my app so new users can have an easier time understanding how to start. I found android's OnboardingSupportFragment, but aftering trying to implement it and failing I decided that I would just make my own custom dialog. Has anyone used OnboardingSupportFragment? And if so, do you have an example of its usage?

    Best way to view different settings screens?

    Posted: 14 Jan 2021 07:03 AM PST

    I work on an app that gathers travel traces for users, especially when they're not actively engaged with their phones. I put in some high-level checking to see if location services are on for the phone, allowed for the app, allowed in background mode, is in high accuracy mode, etc. It's now time to do a couple of things - I want to tailor the messages about what settings need to change to what the user sees (by Android version, manufacturer, carrier?, ...?), and to be able to explore settings when things go wrong - things like 'battery saving' have caused trouble, and I'm sure there'll be others...

    I know there are services with emulators, but I doubt those would have options for manufacturer, etc. - good assumption?

    The other option I was thinking about were testing services that use actual devices, but I wasn't sure if I'd get access to the settings screens through those.

    Anyone have experience with this, and recommendations?

    Building an app for my rPi meteo station.

    Posted: 14 Jan 2021 12:55 AM PST

    To begin with, I am an absolute novice and have no prior knowledge to the topic of Android developing. The only thing I want to ask you, the experienced ones: Would it be posible to build an Android app from scratch (preferably with Python) for my raspberry pi powered meteo station? To be more precise: I would like to have my app on the Play Store and all it would offer is the data from my sensors on the raspberry pi meteo station. Is this legally and technically possible?

    Thank you and sorry if this is a stupid or inappropriate question.

    Phones with biometric face unlock

    Posted: 13 Jan 2021 11:55 PM PST

    For testing purposes I need a device with biometric face unlock (not only face lock screen but "real" biometric face unlock that is available in the biometric prompt). Does anybody have a list of phones that have this feature?

    google admob ids

    Posted: 13 Jan 2021 11:29 PM PST

    I have an app in the Google Play and would like to add a ads banner. The code is published to github and my question is if it is safe to upload the banner id (from layout files) and app id (from Android Manifest). I did not notice any notes telling that one should not give the ids to anyone else.

    What is a clean and fast Android Emulator for Windows PC - with NO focus on gaming

    Posted: 13 Jan 2021 10:51 PM PST

    Hi, I'm in need of a clean and good performance Android Emulator, but most of the ones I find on the internet are focused on gaming (and a lot of ads). Is there something you can suggest that is as clean as stock Android and just allows me to install and run most Android apps? Thanks ...

    My app was suspended, what can I do so my account and apps don't fall in problems?

    Posted: 14 Jan 2021 05:29 AM PST

    Today, I got email that one of my was suspended. It's because one of my screenshots hurts policy, somehow promotes self-harm, they said.

    It was a meme, I never understood that it could be counted as self harm promotion until someone in discord told me. 2days ago, I submitted app update and it resulted into suspension even though google didn't note this in the previous updates.

    The screenshot

    I really feel helpless now, I appealed that it was a meme and I was about to update it, I know it was somehow my mistake. But I feel like they won't accept my request, the feeling when you see everything is against you

    Please suggest me, what should I do now

    Background location access confusion

    Posted: 13 Jan 2021 12:15 PM PST

    I knew that Google had made changes to background location access but since I don't do that I didn't worry much about it. I just got an email saying that my app is using background location.

    My app is a web browser so it only has the location permission for when a user goes to a site that asks for location. I'm guessing that doesn't count as background location usage? So what am I doing wrong?

    React native android app shows white screen when moved to background?

    Posted: 13 Jan 2021 10:11 PM PST

    When I move my React native app to background irrespective on which screen I am on, it shows white screen instead of the screen I should be in? I am using React navigation. I am not sure what code to post. This issue does not happen on ios https://preview.redd.it/yhalbullg3b61.jpg?width=720&format=pjpg&auto=webp&s=a690d3470b7923d8de64d38fa335d86257fd6612

    Best Tutorials for Learning Instrumented Tests in Java

    Posted: 13 Jan 2021 10:01 AM PST

    I've been looking around YouTube on how to do instrumented tests, and so far, almost all of them are written in Kotlin (including the official docs) or using deprecated classes.

    I'm completely new to writing tests (just learned writing unit tests a few days ago), so if there's something you can recommend that can work as a proper walkthrough, it'd be a great help.

    Thank you!
