    Weekly Questions Thread - November 23, 2020

    Posted: 23 Nov 2020 02:56 AM PST

    This thread is for simple questions that don't warrant their own thread (although we suggest checking the sidebar, the wiki, our Discord, or Stack Overflow before posting). Examples of questions:

    • How do I pass data between my Activities?
    • Does anyone have a link to the source for the AOSP messaging app?
    • Is it possible to programmatically change the color of the status bar without targeting API 21?

    Important: Downvotes are strongly discouraged in this thread. Sorting by new is strongly encouraged.

    Large code snippets don't read well on reddit and take up a lot of space, so please don't paste them in your comments. Consider linking Gists instead.

    Have a question about the subreddit or otherwise for /r/androiddev mods? We welcome your mod mail!

    Also, please don't link to Play Store pages or ask for feedback on this thread. Save those for the App Feedback threads we host on Saturdays.

    Android Studio 4.1 icon for Windows without the white background disc

    Posted: 23 Nov 2020 05:22 AM PST

    If you're like me and disliked how the AS 4.1 update added the Androidesque white disc background to the icon, you might like this altered ICO file that enlarges the main icon and removes the background:

    ICO file

    Example before vs after

    Finally an encouragement to the Android developer team: please follow the design guidelines of the host OS, not the target OS.

    Simulating WiFi device in emulator with mac80211_hwsim kernel module

    Posted: 23 Nov 2020 05:50 AM PST

    I am looking to simulate an additional WiFi device in a rooted android emulator (to simulate a device my company makes). So far I have found the linux kernel module, mac80211_hwsim, which seems like it would help me create virtual networks like this. I believe this is also the mechanism that the emulator uses to create its fake wifi network already.

    If this is in fact the right way forward, once I create some more channels for that kernel module, I want to be able to connect to a program on my local computer after connected to this other WiFi network (similar to how 10.0.2.2 maps to the host computer). (https://developer.android.com/studio/run/emulator-networking looks helpful with the redir command)

    Does this sound reasonable and does anyone have some tips going forward? It's been challenging to find information that is relevant to Android in this area.

    Developer account transfer

    Posted: 23 Nov 2020 12:47 AM PST

    Hello everyone, I want to transfer my applications to another google account, and then I have questions that I could not find on the Internet. Perhaps if they answer me well here, this article will be very useful for many.

    1. Does the developer's reputation carry over to the new account? (I have one blocked app)

    2. I have money in my account, will it be transferred to the new account? (I have a paid app)

    3. I have 5 applications, but I want only 3 to be transferred, can the other two be deleted? (not important)

    4. Will the applications disappear from the search during the transfer? (temporarily)

    I have already transferred the Admob and Firebase services in advance to a new account. Thank you all in advance.

    My app is blocked. Reason: A similar application (it is not.) I wrote in support and have been waiting for an answer for more than 5 months, terrible. Because of this, I want to create a new account.

    [Hilt] + navigation scoped viewModels savedStateHandle bug

    Posted: 23 Nov 2020 07:46 AM PST

    Relating to this issue on dagger hilt repository.
    Does anyone know about any workarounds to make it work as expected, except scoping it to activity instead of navigation graph, and giving each fragment its own viewModel ?

    Is Google Play publish review being delayed due to Christmas is near?

    Posted: 23 Nov 2020 07:14 AM PST

    We made some hotfix on some critical bug.

    But it is pending for 2 days.

    Usually, it only take a few hours.

    I was wondering, is it the publishing review process being delayed, due to Christmas is near?

    Do you experience the same thing?

    Update of preloaded Apps without google account

    Posted: 23 Nov 2020 07:06 AM PST

    Hi folks,

    recently I stumbled over this blogpost https://www.androidpolice.com/2019/02/15/google-plans-to-let-preloaded-apps-update-via-google-play-even-if-you-dont-log-in/

    It say's that preloadeded apps on a Android device can be updated even when the user is currently not logged in with a valid google account. My guess is that this is not valid for Apps which where installed from the Playstore?

    In general I found only little information about this. What is a system app / preloaded app, can I make my own system app / preloaded app, do I have to create my own ROM for it and so on.

    Maybe here is someone who could shed some light on this topic.

    Posted: 23 Nov 2020 04:05 AM PST

    So imagine you want to broaden your knowledge and learn new things and ideas that you can bring into your Android development from other platforms. Which one do you think would be most beneficial and why?

    If you choose any, feel free to share your opinion or experience about that or any specific platform or language you recommend to learn.

    Translating Design to Code Battles

    Posted: 22 Nov 2020 06:33 PM PST

    I am working on an app. The designer designed the app with IOS in mind. Each step of the way in translating the design into code has been a battle. Sometimes i feel like i am losing the war.. lmao

    The latest war involves creating an inner blur radius and also an outer one with a specific color.

    It makes me wonder whether other android devs especially ones who have had years of experience also go through this

    If anyone has gone through this . i would love stories, it would help my troubled mind to have moment of calm

    App shortcut icons no longer tappable? (Pixel 5 launcher/Android 11?)

    Posted: 22 Nov 2020 07:17 PM PST

    App shortcut icons no longer tappable? (Pixel 5 launcher/Android 11?)

    Has anyone else observed that app shortcut icons are no longer tappable? See pic below. I'm able to reproduce this on my Pixel 5 running Android 11 but I'm not sure if this is due to a change in the Pixel launcher or in Android 11. I don't believe we've changed any of our code around shortcuts recently.

    It's a bit frustrating as a user because tapping the big FAB-like icon is a pretty natural thing to do. Thanks in advance for any data points or insights :)

    Recommended way to update Firebase db

    Posted: 22 Nov 2020 10:12 PM PST

    My app will register a lot of users (if it is successful) and it is all stored in the Firebase real-time DB. I will need to query the DB to look at data and give approvals. What is the recommended way to implement this? I was thinking of making an admin login in the app, where I can query the DB, I believe this is how it is commonly done. But alternatively I could query the DB directly, as a web-based solution. Would love to hear from someone with experience.

    Weird Behavior of Fragment and ListAdapter

    Posted: 22 Nov 2020 05:48 PM PST

    Hello, have anyone of you noticed that ListAdapter doesn't show update the RecyclerView when a change in the data set happened? So in my app, a dialog fragment appears to make the user input a data, then this data is returned to its parent (an activity) and the parent's viewmodel is in charge of inserting/updating it to the room database. ListAdapter doesn't show the changes, and it needs another insert/update to show both changes to the RecyclerView, but when I use ListAdapter+startActivityForResult / notifyDataSetChanged+FragmentResult is just works fine.

    please be gentle, I am new to this sort of things :)

    Android serious games on the topic of farming

    Posted: 23 Nov 2020 01:03 AM PST

    Hi everyone!

    As an android game developer, I've always wanted to explore new areas in terms of topics to build games around. Therefore, me and a colleague have decided to study the impact of serious games and are taking as sample the area of farming related educative games.

    We are currently performing research in this regard in order to shape our next android farming game.

    If you can spare 3 minutes, please answer our survey for game developers at:

    Your thoughts on DataBinding?

    Posted: 22 Nov 2020 12:24 PM PST

    In my personal projects I avoid it, but I've used it a fair bit at work and I dislike it quite a bit.

    pros:
    - Reduces LoC in your Activity/ Fragment classes

    - Works well with some libraries like Epoxy

    cons:

    - Introduces additional points of failure

    - Reduces code flexibility

    - Often requires cleaning and rebuilding your app which makes productivity suffer

    - Doesn't really clean up your code, just offloads the mess

    I wonder what your impressions are. Do you like it? Do you think I'm mistaken and/or missing the point or is DataBinding as annoying for you as it is for me.

    A question for experienced devs: Are you building apps, or simply maintaining apps?

    Posted: 22 Nov 2020 09:30 AM PST

    So many of the sources I read or study with go over the tools and skills necessary to build an app, usually something small like a news feed or a habit tracker. While understanding these concepts are surely vital to the job, are you using every single one every single day?

    This is an area I find many people trying to get into the industry have no perspective on, for obvious reasons. Of course it's important for people to understand XML, coroutines, Room, etc., but many people in this early position develop the misconception they need to, for instance, be able to build a multi-functional app instead of work with people to just maintain one.

    With that context, how should a person in this early position prepare for the workplace? I've found the Google Associate Developer certification to be a fairly reliable measurement for a junior's ability to perform, but I would love to have some greater perspective on the topic.

    Thanks in advance.
