    I created a library to help determine when the app UI is visible

    Posted: 11 Aug 2021 06:06 AM PDT

    I wanted to determine when the app UI was visible, and take actions based on that. My main purpose for doing this was to stop unnecessary background work when my app was no longer visible.

    It provides an Observable<Boolean> that tells you when the app UI is visible - true means some activity of the app is visible, and false means none of the apps' activities are currently visible.

    Here's the link - https://gitlab.com/sandeep_r_89/appvisible

    It's under the MIT license so you can modify it and incorporate it in your apps as you wish. I chose to use RxJava 3 and the Jetpack startup library, but you can change it to whatever you want to use.

    Please let me know if you have any concerns, questions, suggestions or bugs to report.

    How do you guys manage forms?

    Posted: 11 Aug 2021 02:49 AM PDT

    A little bit about myself, I'm the sole Android dev in my company and I've made and shipped many apps throughout the years. I like Android dev a lot. Started around 2013.

    My work involves data collection so a considerable amount of the apps I've made/maintain include long forms. I'm talking forms that take at least 10 minutes to fill and span multiple pages. I separate them into different pages to improve performance. Many forms also require having dynamic fields that can be added or removed as the user wishes.

    I use MVVM and the usual suspects (Retrofit, Hilt, Moshi, Jetpack Navigation, kotlin, coroutines, room…) but form validation is always done "manually" since there are so many requirements and edge cases in the form. I thought it would be a good idea to get input from fellow Android devs and get an idea of how different people do things.

    I guess my question is, how do you guys manage forms? Do you put fields in an array and validate them in bulk? DataBinding is great but I've realized that when the form contains dynamic fields it doesn't help at all.

    How I do it: when possible, without affecting the UX, I group edit texts together and then loop through them and raise an error if they're empty, but there are individual fields with edge cases such as phone numbers which must start with a specific country code, national ids with specific starting numbers… those must be verified too. Then for components such as radio buttons or checkboxes I use their change listeners and update the data model as they change. I also use the change listeners to hide/show content as needed.

    For dynamic forms, I inflate a custom layout view and add it to a linearlayout and a view arraylist. when the user wishes to remove that item, I clear it from the linearlayout and from the view arraylist as well. When they tap submit, I loop through all views in the dynamic list and using the ids of the fields inside them I can validate them accordingly and rise errors if something is not properly filled.

    So far, I haven't had a problem with this approach. After all, the apps work even on low end phones with no lag. Just wondering how you guys do things :)

    Newbie question on when to use SQLite

    Posted: 11 Aug 2021 07:31 AM PDT

    I have only been using MySQL and totally new to SQLite.
    From reading some online descriptions, my impression is that a SQLite DB is available for each Android's app through class MyOwnSQLiteDB extends SQLIteOpenHelper and the database is local to that app only. It is a relational database to local data vs SharePreferences being key/value with limited capacity.

    Hence, when data are stored in it using execSQL("INSET INTO friends (friend1, friend2) VALUES ('trump', 'biden')"), those data are only available to that app on that phone. So SQLite is suitable for apps that extensively use local data such as a ContactManager, Calendar, etc, but unsuitable for apps like a social network whose data like a friends table must be synchronized/centralized across all users. Is that understanding right?

    Play Store submission - promote directly from internal testing to production or create alpha first?

    Posted: 11 Aug 2021 08:41 AM PDT

    When submitting a new app to Play Store, I first submitted it in the internal release track.

    Then the dropdown showed an option to promote to production. So I directly promoted the internal testing release to prod.

    ​

    1. Was this the right approach?
    2. Should I have promoted it to alpha first?
    3. It is still under review for 3 days. Is it advisable at this stage to promote from the same testing release to alpha first?

    So I tried asking Google to delete some of my old Apps.

    Posted: 10 Aug 2021 02:36 PM PDT

    Just leaving this here in case anyone is curious.

    I used the support (?) on the top right of the Dev Console, searched for Delete App then skipped the FAQ and selected Contact Us, one of the recommended options you can select in issue is Delete App, skip FAQ again, choose Email, then you should get a form to fill out the Apps you want to delete etc.

    All the Apps I asked them to delete had ZERO current installs because I had unpublished them years ago, but it turns out you can only delete Apps that have never been installed by anyone ever so pretty much Apps which you release by mistake and realize immediately.

    Here is part of the response:

    Hi ,

    Thanks for contacting Google Play Developer Support.

    We can process an app deletion only if the app meets all of the following criteria:

    • App must be in good standing (not rejected, removed, or suspended)

      App must have 0 lifetime installs (Bolding theirs)

      *App must not be in review

      *App must be unpublished for 24 hours

    As all of the apps for deletion have install statistics, we are not able to delete the following apps at this time:

    com.package.id

    com.anotherpackage.id

    Please let me know if you have any other questions or concerns about the >Play Console. Regards

    How to choose app to work on if you suffer from analysis-paralysis?

    Posted: 11 Aug 2021 02:47 AM PDT

    I'm working in a small team of app devs for a few years now on a single app and we want to create a new game app or utility app.

    Problem is: there are many games we could work on or utility apps, but we just can't choose which one is best to focus on.

    Any tips, videos, articles how to make the choice?

    Anyone have examples or resources to learn about app architectures that support offline mode using "deltas"?

    Posted: 10 Aug 2021 08:16 PM PDT

    I'm trying to get better at mobile system design, specifically related to android. I saw this great blog post by dropbox from 2014 that talks about how they implemented offline mode using a concept of a "delta" object: https://dropbox.tech/mobile/building-carousel-part-i-how-we-made-our-networked-mobile-app-feel-fast-and-local

    I then found an article from Trello where they also talked about building an offline mode for the app using "deltas"

    Does anyone know if there are some tutorials somewhere, or github projects that would be good to learn about this concept? I know it's quite a complicated topic and there probably aren't many tutorials but perhaps someone here knows of something.

    If you have multiple accounts then link all those accounts.

    Posted: 10 Aug 2021 10:17 PM PDT

    If you have multiple accounts then link all those accounts in given form otherwise google will suspend those accounts of yours under "associated account" because google will consider this action of yours as deceiving google to get 15% discount(from its new policy) on your each accounts.

    While Google is giving 15% discount only to one account even if you have multiple accounts. Having multiple accounts isn't against Google's policy but not letting know google about your associated accounts will put you in trouble against the policy of deceiving google to get discounts on each accounts of yours.

    Singleton alternatives

    Posted: 10 Aug 2021 11:23 AM PDT

    I am building an SDK library and have read that singletons are evil, especially in android so here is my dilema.

    I have an SDK:

    public class CoolSDK { public static void init(Context context, String client_id) { ... } public static void doSomeCoolStuff(){ ... // needs client id } public class ClientActivity extends Activity { public void onCreate(){ CoolSDK.init(this, "client69"); } } public class SomeActivity extends Activity { public void onCreate(){ CoolSDK.doSomeCoolStuff(); } }

    So if I can use singletons I can create one that will hold the client id and now every time when the client calls doSomeCoolStuff() from anywhere (fragment, activity, service whatever) I can get the client_id from that singleton and use it whenever the client app is requesting the method, how can I achieve that without singletons ? (also note that doSomeCoolStuff() is using a retrofit client thats coming from a singleton so I dont have to create a new one every time)

    Someone offering to buy my dev account.

    Posted: 10 Aug 2021 10:04 AM PDT

    I just got an email that when translated is someone trying offering to buy my developer account.

    I have no intention of selling, my apps weren't even good and it's just not worth my time. Plus it's the account name is literally my IRL name.

    But I am wondering what sort of scam this is? Someone trying to get access to a valid account so they can push to play store? Or maybe they I Want to confirm my email to scam me.
