Weekly Questions Thread - July 06, 2020

Posted: 06 Jul 2020 03:57 AM PDT

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.

Why are simple things sometimes so complex [mini rant]

Posted: 06 Jul 2020 05:39 AM PDT

So I have a spinner (drop-down select, the naming of this thing is another rant) and I have a blue background and want to change the text colour to white, sounds simple, right?

to do that I have to create TWO layout resources (one for selected item and one for dropdown) and in code declare an adapter which needs the item array (cause the reference in XML is not enough), context, and the resource for the style of the selected item. then on a separate line I have to declare a separate resource for the items in the drop-down menu.

I JUST WANTED TO CHANGE THE TEXT COLOUR!!!!! why do does this need two extra XML files and 3 lines of code!? it sometimes feels like a lot of the android API is specifically made to have as many files in a project as possible

Payment declined for ~ 70% of in-app purchases

Posted: 06 Jul 2020 04:25 AM PDT

I have an Android app with about 300k installs with in-app purchases (one time and recurring).

I have one issue though, about 60-70% of the orders are being marked as "Payment declined".

When I click on the declined orders I see "There was an issue charging the customer's payment method" and "This order could not be completed and was canceled".

They're not coming from a specific country/user, and 70% decline rate is very high.

I'd appreciate any help regarding this issue.

Building a multi-module project

Posted: 06 Jul 2020 12:29 AM PDT

Hi guys, sorry to be posting this here but couldn't find an answer for this anywhere:

What I have:

a multi-module project that works fine.
Project is stored in Git and each sub-module has it's own repository.
No problems with references or anything like that, again - functionally it works just fine.

The "problem":

My team and I work on the project by opening all the modules in the same Android Studio window, we see all the module in the same tree and we can open each one just fine (noted here since that might be related, IDK). If we change a file/class/asset/something in one of the submodules, and then want to run the application with the new change, we have to "rebuild" instead of "build" which takes extra time and doesn't happen automatically like regular "build" which occurs before each run.

If we "build" the specific sub-module that was changed, the change isn't recognised when we run the app.

Is that normal? did we miss something in the configuration? Is there a way to make the project build all the submodules with the "build" command instead of the "rebuild"? Is it not supposed to? Any input would be appreciated :)

Course for experienced developers

Posted: 06 Jul 2020 06:27 AM PDT

Hi, I am looking for an Android with Kotlin course for experienced developers. I have been in the field for 10 years and I am not wasting 60 hours listening to how to declare a variable. Do you know of any good courses? Couldn't find any by just googling.

How to do a splashscreen the right way?

Posted: 05 Jul 2020 10:13 AM PDT

I've seen countless videos where people are saying to make a splash screen occur for a set amount of time. I know this is wrong, yet I can't find any resources to do a splash screen the right way, any help?

How to best debug bluetooth connectivity?

Posted: 06 Jul 2020 02:46 AM PDT

Hey guys, I started a new job as android dev, and the app Im working on utilises BLE and iBeacon to connect to a small device. It usually works pretty well, but some users are reporting connectivity issues, constant disconnects and reconnects, cannot connect at all, etc.

I cannot replicate these issues on my own test devices, even if they are the same models being reported. My experience with BLE is pretty low, so I'd love some resources on how best to work with it on android. Any suggestions?

Can you reuse the same privacy policy

Posted: 06 Jul 2020 02:48 AM PDT

if both games are the same in terms of data collection and everything else do you need a new one for each game?

Which ViewGroup are the best to hold only one child?

Posted: 06 Jul 2020 02:43 AM PDT

Usually I'd pick LinearLayout for this, but is there any better option? Only needed for wrapping the view for UI stuff. Thanks!

What do you use for long running tasks since Loaders and AsyncTask have been deprecated ?

Posted: 06 Jul 2020 01:55 AM PDT

Hello, Loaders and AsyncTask were really easy to use and helpful classes for long running operations like performing network http requests, but since they are deprecated, I couldn't find an alternative. I know that I may use LiveData + ViewModel as Google suggests but they are not doing tasks in a separate thread, so what can we use besides them? RxJava? or sth else?

How to update single item while using paging 3 with network only ?

Posted: 06 Jul 2020 01:32 AM PDT

I wanna do something like updating the item's favorite state in UI after I updated the server with new state just for a single item of the list.
but the current paging library won't allow it.
The only solution for now is to use with database and update the db.
but there should be a solution for network only usecase too.
