            Android: Iterative queue-based flood fill algorithm 'expandToNeighborsWithMap()' function is unusually slow
            Asked 2021-Dec-30 at 04:27

            (Solution has been found, please avoid reading on.)

            I am creating a pixel art editor for Android, and as for all pixel art editors, a paint bucket (fill tool) is a must need.

            To do this, I did some research on flood fill algorithms online.

            I stumbled across the following video which explained how to implement an iterative flood fill algorithm in your code. The code used in the video was JavaScript, but I was easily able to convert the code from the video to Kotlin:


            Here is an excerpt of the JavaScript code from the video:

            Converted code:



            Answered 2021-Dec-29 at 08:28

            I think the performance issue is because of expandToNeighbors method generates 4 points all the time. It becomes crucial on the border, where you'd better generate 3 (or even 2 on corner) points, so extra point is current position again. So first border point doubles following points count, second one doubles it again (now it's x4) and so on.

            If I'm right, you saw not the slow method work, but it was called too often.



            Mandatory Consent for Admob User Messaging Platform
            Asked 2021-Dec-12 at 16:09

            I switched from the deprecated GDPR Consent Library to the new User Messaging Platform, and used the code as stated in the documentation.

            I noticed that when the user clicks on Manage Options then Confirm choices, ads will stop displaying altogether (Ad failed to load, no ad config), and I can't find anyway to check if the user didn't consent to the use of personal data.

            This is problematic as my app relies purely on ads, and I will be losing money if ads don't show up, so I want to make it mandatory for users to consent to the use of their personal data, otherwise the app should be unusable.

            I have made a test project on Github so everyone can test this behavior. If you are not using an emulator, then you need to change the "TEST_DEVICE_ID" to yours.

            How can I achieve this?



            Answered 2021-Nov-02 at 17:50

            I found a workaround for this, but this is no final official solution.

            It seems that if a user consented to Personalized ads, a string in SharedPreferences, which key is IABTCF_VendorConsents, will contain ones and zeros corresponding to some vendors (I think). If he didn't consent, this string will be equal to 0.



            Huawei auth service integration with .net core 3.1, unable to validate JWT
            Asked 2021-Nov-12 at 17:04

            We have a react-native application running in production with firebase phone auth. Lately, we received feedback from users owning new Huawei devices not being able to authenticate with their phone numbers using firebase.

            Since a lot of users started having this issue, we decided to implement Huawei auth services only for devices under HarmonyOS and keep the regular firebase phone authentication for other users.

            After integrating the Huawei App Gallery Connect Auth SDK in our react-native app, we are able to receive the OTP and sign the user in using credentialWithVerifyCode and we are also able to retrieve the user's token using

            Android 12: How to prevent activity restart on changing phone wallpaper?
            Asked 2021-Nov-06 at 05:20

            On Android 12,

            1. If we open an activity

            2. Go to the home screen of the phone to change the wallpaper

            3. Switch back to our activity, the activity restarts.

            It seems it is related to the Material You theming.

            I would like to disable the restarting of activity when my app comes to the foreground. Is there a way?



            Answered 2021-Oct-31 at 18:39

            It is a non-traditional configuration change. By "non-traditional", I mean that it cannot be blocked by android:configChanges — your activity will be destroyed and recreated whether you like it or not.

            If you have Configuration objects from before and after the change, you can determine that this scenario occurred by calling diff() on the newer Configuration to compare it to the older one:



            Why did Android Application start 3 times on single launch?

            Answered 2021-Nov-05 at 03:21

            Apparently, it's an Android Studio filtering issue. I'm having the Tracking there to filter the log. And it shows multiple log of the same type.

            When I remove a character from the log, then the filter get corrected. After putting back the character, the filter is still okay.

            I'm starting to get errors when I am executing a test for a release variant which was always working fine. The code has always been executed in a Docker container so we can ensure that the build will always be clean.

            Answered 2021-Sep-03 at 11:31

            I've found the issue and I was able to fix it.

            The issue was that one of the external libraries the app depends on has a dependency on androidx.core:core-ktx:+ which meant that was always compiling with the latest version. My app is still working on SDK 28, but the latest version of androidx.core:core-ktx has the minimal SDK of 31, which resulted in this conflict.
