    How can I secure my game from fraud and abuse?

    Posted: 03 Jun 2021 06:43 AM PDT

    I have a game uses Firestore, When the player complete the certain level the game will give him 50 points and will be save the data in Firestore.

    Let's suppose someone did reverse engineering for my game and made change from 50 points to 1000 points in code and he rebuild the APK and play my game with the same Firestore database, Now when the player complete certain level the game will give him 1000 points and will be save the data in Firestore and that considered hacked data.

    I don't care if someone did reverse engineering of my game and republish it as new game with his own Firestore, But I care about hackers who changed the data on my Firestore

    How can I secure my game from fraud and abuse.

    Account banned from Google Play

    Posted: 03 Jun 2021 03:50 PM PDT

    Hello guys, I started making Android apps a few months ago. I saw many apps such as wallpapers apps, fake call apps, soundboard apps on Google Play and they had a lot of downloads so I decided to give it a try and uploaded some fake call celebrities apps. Everything was ok at first until I received some warnings on AdMob; it was because I used AppGeyser service to quickly make a « fishing » game. They basically gave me a template but I guess tons of other devs used this template and Google flagged this as a « copycat ». They removed this app from the Google Play store but not the other « fake call » and « wallpaper » apps. I received a few other warnings for mistakes in ads implementation (problems with the banner size, interstitials popping up at the wrong moment) but nothing about copyright or my content itself. I was making around 30$/day on AdMob and reached around 40k installs when suddenly I got banned from AdMob for « invalid activity ». It seems I forgot to use test ads when testing my apps (even though I never « self clicked » on my apps it seems I generated fake impressions). But at least I still had my Google Play account. Then about 2 weeks later I got my Google Play Developer account suspended. I know that as a junior developer I made some mistakes (didn't use test ads, used copyrighted content). But they didn't tell me exactly why I got banned. Repetitive content ? Problems of copyright in the photos/videos ? Use of celebrities names in the metadata ? Absence of GDPR policy in my apps ? I know I did things wrong but I would like to know precisely what went wrong to avoid making the same mistakes later. Now I'm asking myself a few questions. 1. It seems there is tons of apps infringing copyright on the Google Play Store. This is why I thought I could do the same kind of apps myself. It seems that these apps stay around for a few months until the developer gets banned. Do you guys know about this phenomenon ? It seems that this kind of app generate a lot downloads. I would have prefered Google to refuse my app and explain me why at first rather than telling me that everything was ok and before banning me. Plus it seems that they will keep the money that I generated with AdMob ! 2. Now what to do ? I have another google play account under my companies' name (the account that was banned was under my personal name) without any app for the moment. I also have an other AdMob account under my company's name, but I linked some ad units of this account to the apps that were banned. Are they going to ban my other Google Play developer and AdMob accounts ? Will I be able to re-open an account and upload apps again one day ? I appealed the ban from Google Play store but I know it is useless. I really hate the way they work ! At least they should give people a second chance ! I really wanted to do good things and respect the policies. I just lacked of knowledge and experience and for this reason now I'm banned forever. Last question: do you guys have any experience with other ad networks ? Facebook audience network for exemple ? I might have to make only iOS apps and avoid AdMob for monetization... Thanks a lot for your help.

    How do I figure out the monthly fee I should charge my users for premium access in order to make my app profitable?

    Posted: 03 Jun 2021 03:05 PM PDT

    My app that will be available for both Android and iOS will use the following paid services:

    • Firebase Cloud Firestore
    • Firebase Cloud Functions
    • Firebase Cloud Storage
    • Firebase Realtime Database
    • Spoonacular API (using Edamam Recipe Search API right now, but most likely will switch to Spoonacular because it's far more affordable)

    With all of these services in use, how do I figure out how much the monthly fee for the premium subscription should be so my app is profitable? Right now I've decided to limit the freemium model to four API calls every 24 hours for every user, but if the user upgrades to premium then it's unlimited for them.

    Starting in late 2021, when a user opts out of interest-based advertising or ads personalization, the advertising identifier will not be available. You will receive a string of zeros in place of the identifier.

    Synchronize stored data locally with the Rest API continuously

    Posted: 03 Jun 2021 05:14 AM PDT

    Hi there, this is the first question for me here so I'm excited to hear your opinions.

    Now I'm wokring on an app that comunicate with Rest API, There are some data that I need for multiple screen always sush as (user info) so I will save them into Room(local database), but these data maybe changed in Rest API at any time, then the data which exists in Room will be Mismatched with the API data.

    So I'm wondering what is the best practise to make the data in Room matched Rest Api data always, in other words, I want to reflect any change oocurr in Rest Api to Room database as soon as occurred in somehow.

    sorry for bad english and big thank to google translate :)

    App having FIS_AUTH_ERROR issues for some - we can't replicate in house - need help

    Posted: 03 Jun 2021 09:20 AM PDT

    Fatal Exception: com.google.android.gms.tasks.RuntimeExecutionException
    java.io.IOException: FIS_AUTH_ERROR

    We did a release with updated Google Firebase libraries and are getting this in the field. I updated to absolute latest libraries and grabbed lates google-services.json file from the firebase console and did a hot-fix. Still having issues.

    Then I backed it all out with original Firebase Library versions and original google-services.json files did a hot-fix and STILL having the crash.

    Right now I am fully reverting everything so going back a full version of our app to get people back to working.

    Looking for ideas on how to replicate this problem. We have tried fresh installs, updates, etc. on all the hardware we have available but have never run into this issue. I find references to is out on Stack Overflow on what not but never have found a way to replicate it so we know in the future if we have actually fixed the problem.

    Trying to download internal test track, keep getting live version instead

    Posted: 03 Jun 2021 08:05 AM PDT

    Hi friends, I'm not a developer, but I'm trying to download an internal test track version of an app.

    I was shared the link, and it clearly says on the goolge playstore screen Appname (Internal Beta), but when I click download, I keep getting the live version. (my email is added on the console as a tester)

    What do you think may be the issue? thanks

    Your suggestions about a recipe app

    Your suggestions about a recipe app

    Hello,I'm developing a recipe app without API. Basically there'll be a clickable list in a fragment and that lead us to details fragment.I'm very beginner level to MVVM,Room,Hilt etc.I'm planning to use Firebase to save my recipe datas and images.

    I want to know your suggestions like "This isn't best way to do this so try this one" or "You can't do this with MVVM" because I'm confused right now.I watched a instructor and he was using model class to fetch data from API but I don't know how to fetch data and show in a fragment in MVVM.

    Thanks(I'm Kotlin user)
