    Weekly Questions Thread - March 30, 2020

    Posted: 30 Mar 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.

    What do you use to design your app?

    Posted: 30 Mar 2020 06:22 AM PDT

    I've been using Lunacy for a while now and was wondering how you do it for your apps? What's your process of coming up with a good design?

    Posted: 30 Mar 2020 02:27 AM PDT

    Hi,

    I had some free time and I made a simple app that displays current info about Covid cases.

    Maybe someone will find this code useful, every feedback appreciated.

    App is using Kotlin (flow + coroutines), MPAndroidChart, Koin, Navigation and more (complete info in GitHub readme).

    More tests are coming soon :D

    New Android Developer. Is it worth it to team up with someone else and develop an app together or is that a bad idea?

    Posted: 30 Mar 2020 10:49 AM PDT

    Just like in your opinion. Would you do this?

    EDIT: And where would one find a partner or team for this?

    Looking for Android Dev topics to write on. Need suggestions!

    Posted: 30 Mar 2020 07:00 AM PDT

    I regularly write about android development on my blog, but have recently ran out of ideas.

    What do you guys think would be a good topic that would help everyone? I'd be willing to learn it and write an article about it!

    Let me know in the comments.

    Anyone else have a 90% drop in ad CPM since mid-March?

    Posted: 30 Mar 2020 06:20 AM PDT

    Title pretty much sums it up. Since the Covid-19 outbreak hit the fan in mid-March the only numbers that have changed for any of my apps is the ad CPM. I am getting just absolutely f*cked. If this continues I doubt I'll even break the $100 payout threshold in April.

    Anyone else having the same experience?

    If I want to start learning to code for any platform, but have a current project idea for Android specifically, would it be adequate to use e.g. Python, or should I just focus on Kotlin?

    Posted: 30 Mar 2020 09:36 AM PDT

    If there are adequate tools/libraries to run compile Python code to (native?) Android apks (like BeeWare? Is it good enough and being maintained?), then I think I should stick to Python, but please let me know.

    Not searchable on Google Play

    Posted: 30 Mar 2020 09:32 AM PDT

    I took a look at stack overflow earlier to see it there was a quick answer, but there dosent seem to be. I uploaded my app (Imperium) to the play store about a week ago. It's a full release, so it's not a beta or anything, but searching for it on the play store, it doesn't show up (it is compatible with my device and available in my country). However it is on the play store, it can be accessed just fine by link, it just can't be searched even with quotes around it. If there's any thing that I'm missing, please let me know!

    I added data retention to Firebase UI's FirestorePagingAdapter

    Posted: 30 Mar 2020 01:54 AM PDT

    This is pretty basic for what I need, I'm hoping a better way will be added on 6.3.0:

    ViewModel:

    // Use your preffered config private val config = PagedList.Config.Builder() .setEnablePlaceholders(false) .setPrefetchDistance(2) .setPageSize(2) .build() // firestoreRepo.getPets() is a Firestore Query private val factoryPetShop = FirestoreDataSource.Factory(firestoreRepo.getPets(), Source.DEFAULT) val liveDataPetShop = LivePagedListBuilder(factoryPetShop, config).build() 

    FirestorePagingOptions:

    fun build(data : LiveData<PagedList<DocumentSnapshot>>, parser: ClassSnapshotParser<T>): FirestorePagingOptions<T> = FirestorePagingOptions(data, parser, DefaultSnapshotDiffCallback(parser), mOwner) 

    I use the LiveData from my ViewModel to pass it to FirestorePagingOptions.Builder.

    This way, the data is still retained upon fragment destroy and FirestorePagingAdapter doesn't have to query for the data again, so I can save my recycler view's scroll position.

    Here's the GitHub issue in Firebase-UI

    Trying to do an internal test on playstore with email list of testers, just checking this won't inadvertently deploy to production?

    Posted: 30 Mar 2020 03:22 AM PDT

    Trying to do an internal test on playstore with email list of testers, just checking this won't inadvertently deploy to production?

    So the app is not released yet and I just want my email list of testers to be able to access it.

    So far my email testers have not got any email yet, and I'm wondering if I need to click 'release to production' (see screenshot). To 'release to production' means release to the entire world and not to your test group, but in this context maybe that's what google play means? Just checking it's safe to click that button. 2 part screenshot cause I couldn't fit it on 1 page.

    Also I have filled out the email list and it is under 'testers' in the below screenshot. Also not sure what the difference is between internal and alpha test or are they the same thing? Think there was a button where 'release to production' is now that I thought was going to email my testers with a link, but it did not. Any advice appreciated. thanks

    edit: ok just checked the main application page now and the app is showing as 'pending publication', perhaps my testers will be notified when that goes through? i didnt put much effort into the screenshots, icon cover image etc because this is just a prototype so just want to get it quick and dirty up and running. hopefully playstore will not block it because of that

    edit2: ok thanks to the replies i understand now. i need to wait until it has passed 'pending publication' and then will be able to send off opt-in link to my testers. cheers

    What kind of business service (app dev market industry) is this?

    Posted: 30 Mar 2020 09:16 AM PDT

    Hey guys, hope you all are doing good.

    I'm not a developer but was trying to understand a pre-app-development (I'm sure the term is not right) business market I stumbled upon recently.

    I'd like to know what kind of business service is this website? What is this market? What are any google searches someone will use to land on these kind of sites?

    So far I have been able to grasp some keyword ideas and searchable phrases for this specific area.

    These are as follows - Pre app development, app bundle, application bundle, clone development, professional app developer, build app bundle, clone app design, professional app development , custom app creation.

    Would really appreciate your help on this!

    I am trying to read text from a .txt file in my internal storage in android studio

    Posted: 30 Mar 2020 08:55 AM PDT

    TextView textid; textid = findViewById(R.id.textid); File file = new File("/storage/emulated/0/hey.txt"); StringBuilder text = new StringBuilder(); try { BufferedReader br = new BufferedReader(new FileReader(file)); String line; while((line = br.readLine())!=null) { text.append(line); text.append("\n"); } Log.i("text", text); textid.setText(text); } catch (Exception e) { e.printStackTrace(); } 

    According to my requirements I need to mention the path of the file in the code itself. This isnt working, moreover, I dont see anything in the logs too. How would i implement this? Also, how would i write into a file with a specified path?

    App to find Emergency Essentials

    Posted: 30 Mar 2020 06:33 AM PDT

    I just finished developing an Android app that allows users to find and submit locations where they can obtain emergency essentials. The app is called I See TP, it just hit the store yesterday and is in beta mode. I would love for you to download it and give me your feedback, comments, critiques, bug reports, inquiries, etc.

    Items that the app currently tracks are toilet paper, masks, sanitizer, lysol wipes, water, rice, ramen, and milk. This is a live production version so chances are there aren't any locations in your area yet. If you do add a location, please add one that you were at recently. Users are allowed to submit, edit, and report locations without creating an account.

    The app can be downloaded from the Google Play Store here: https://play.google.com/store/apps/details?id=net.heinousgames.app.iseetp&hl=en_US.

    We also have a website at: https://www.iseetp.com

    You can leave comments here or email feedback to [stevenhanus@iseetp.com](mailto:stevenhanus@iseetp.com).
