    Which technologies would you recommend for a simple 2D game?

    Posted: 31 Dec 2020 05:52 AM PST

    Hi all,

    I'm starting a little project consisting of a Tamagotchi-like virtual pet, and I'd need some advice on how to get started. I've only ever developed native apps on Android Studio with Jetpack, but I assume I'd need some sort of lightweight framework to build a game...

    Thanks in advance for any help you can provide!

    Google Play's new policy for News apps

    Posted: 31 Dec 2020 04:31 AM PST

    Let us know whether your app is a news app

    You must let us know whether your app is a news app by January 25, 2021, or you might be blocked from releasing updates. This helps us make sure you comply with the Google Play News policy.

    This policy requires news apps to show clear ownership of the app and provide ownership information about in-app news content

    There is also the option where we can choose if our app is a News App or Not.

    What if your app is an RSS aggregator app and what will happen if we select the app as not News App?

    What is the best procedure to deal with passwords of user accounts?

    Posted: 30 Dec 2020 09:58 PM PST

    I am working on a app which will have user accounts, hence passwords to deal with. The app will have a Firebase backend and I thought storing the passwords in the firebase database might be an option.
    Storing passwords as plaintext is too dumb of a practice. Hence I surely need to hash it. However, which method should be appropriate? (I know basics of MD5 which is no longer dependable, SHA1 and SHA256)
    Also, I have no knowledge about salting hashes.

    Work with publisher for mobile game?

    Posted: 31 Dec 2020 03:36 AM PST

    Hey. I am an Indie Dev for like half a year now and I'm about to finish a mobile game, that in my opinion is good enough to promote etc.

    I already googled a bit and stuff but would like to hear some personal opinions here.

    all I want is, that many people play my game and have fun with it. it's not about the money for me. which is why I think of writing to some publishers like voodoo etc. the thing is I heard many bad things about them. especially about voodo. For example, that if you send in a game, that they reject you're idea and then like copy your idea and make a cheap copy of it and release it as if it would be theirs.

    also, I read in some places, that they often take your money. I read from people, that released their mobile game with a publisher and then they made 2000 dollars with it (2000 dollars for the dev) and that they saw any of their money.

    I also know, that my game would never in any way get many players if I would try to publish it alone. It's no triple-A title. it's just a small funny game.

    so do you guys have any advice for me and maybe know some good publishing companies to work with?

    Related to App Revenue

    Posted: 30 Dec 2020 09:05 PM PST

    App revenue has fallen drastically in December

    We have been doing so well since June 2020. Our app was growing with a 10-15% MOM rate.

    December hasn't been so kind. Our app revenue has fallen by 30% when compared to last month. So far we got the same number of installs and the budget for marketing is also the same.

    What could be the reason for this? Can you guys share some insights?

    How do you decide whether your unit test should be local unit test, or instrument unit test?

    Posted: 30 Dec 2020 09:26 PM PST

    Recently, we just newly exposed to instrument unit test. We notice that it is quite useful in the sense, it is able to capture bugs, which are not able to be detected by local unit test.

    ​

    For instance, during DB migration unit test https://stackoverflow.com/a/65508502/72437 , instrument unit test is way more reliable than local unit test. Robolectric not able to emulate DB behaviour correctly.

    ​

    So, I was wondering, how does you/ your team decide whether a test should be local unit test, or instrument unit test?

    ​

    Currently, our strategy is, we have 2 exact copies of unit tests. One is for local unit test, another is for instrument test (With all the PowerMocks being removed, as we want to emulate as closed as possible to real Android runtime)

    ​

    The problem of such approach is maintenance. As, if we add a test/ modify a test, we need to make sure it is being done in both local unit test and instrument unit test.

    ​

    I was wondering, what is your/ your team strategy, so that you have a set of testing strategy, to avoid bug from escaping into production?

    ​

    Thanks.

    Top 10 Android Intermediate - Advanced Developpment books 2020/2021?

    Posted: 30 Dec 2020 10:30 AM PST

    Hello,

    can someone recommend me some books which are not outdated and which are good to enhance my knowledge and skills in the android development field?

    I don't use Kotlin for programming, so I would prefer it to be a book about android development in Java.

    Thanks in advance :)

    Displaying files from ACTION_OPEN_DOCUMENT_TREE in UI

    Posted: 30 Dec 2020 02:52 PM PST

    Hi everyone, I'm currently working on an app that (as a first step) should display filenames from a user-chosen directory. So far I've got the following basic structure:

    • Use intent ACTION_OPEN_DOCUMENT_TREE to have the user select a directory and save the resulting URI with its permissions.
    • Use methods from DocumentsContract to build the child documents URI (incl. buildChildDocumentsUriUsingTree).
    • Use ContentResolver.query method to get a Cursor to the files.

    My problem is: How can I display the results from that Cursor in my UI? I've already tried quite a bit of stuff and am unsure about how to proceed:

    • Use SimpleCursorAdapter and ListView - this fails because DocumentsProvider doesn't have the necessary column _ID. In addition, I would really like to use RecyclerView instead because of its advantages.
    • Implement my own adapter for RecyclerView - this requires a lot of complicated and costly comparisons between each element for when the Cursor changes (i.e. the query is refreshed) in order to get the animations right.
    • Use the Paging library - this requires me to set limit and offset parameters on the ContentResolver.query call, which doesn't seem to work and looks more like a hack anyway for API <26.

    I'm sure that at least some of those ways could work, I just don't know the right one. Can anyone here point me in the right direction?

    Should I build my group chat app with cloud functions now or later?

    Posted: 30 Dec 2020 11:34 AM PST

    This is my first real app that I will be putting on the market. I've dabbled in some other Java app projects, but wouldn't even call myself a mobile developer's brother. I've been working in Kotlin and building it slowly so far when I found a 12-video "Get to know Cloud Firestore" series on youtube. In it, the guy explains that it is safer to use cloud functions. At this point I'm like 25% done with the app. Should I switch to doing everything with cloud functions to optimize for security or finish the app using all client side code?

    Copyright protections, app theft, duplications of apps.

    Posted: 30 Dec 2020 09:04 AM PST

    Hi Android Dev community,

    I've been building a fitness app in my free time and close to having a testable version. What is increasingly concerning me is that my app may not find any success at all, but not for being unique with a lot of science/backend development.

    Does anyone have some insights on to how to protect your app's IP, source code, and generally the way it functions? I can imagine my UI design could be adapted and used fairly easily, but I have a lot of back-end (SQLite/firebase) functions that really make it an app that I think stands out, and I've put my heart and soul into it. It would crush me if someone decided to make a clone and it became succesful.

    Any tales, resources, or other guidance would be extremely helpful.

    Cheers,

    Is Kotlin Multiplatform Mobile worth the hassle for new projects?

    Posted: 30 Dec 2020 08:30 AM PST

    I recently read the article https://www.techyourchance.com/kotlin-multiplatform-expert-opinion/

    It got me to rethink about KMM, I know there are following issues with KMM and some are being sorted out.

    • Memory management (being sorted out)
    • Slow build speeds
    • Lack of mature ecosystem
    • Slow performance on iOS

    Jetbrains seems committed improving KMM

    But I am wondering whether KMM worth the hassle for medium size new project at the current state which will be ported to iOS later?

    Posted: 30 Dec 2020 11:37 AM PST

    Hi there, i searched and found out that we can reset reviews on play store for new releases:

    "You told us you wanted a rating based on what your app is today, not what it was years ago, and we agree,"

    https://techcrunch.com/2019/05/08/google-play-is-changing-how-app-ratings-work/

    But i can not find in New play console where to reset or how does it work. Does anyone here knows or had any experience on this ?
