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:

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?

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

I was using def lifecycle_version = "2.3.1" ,

implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version") .

but I had to update version to def lifecycle_version = "2.4.0-alpha03" to use some features, but ViewModelProvider.Factory class doesn't work after I use def lifecycle_version = "2.4.0-alpha03".

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?

I create an app from the template, and populate with some Logs as below

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.

Today for some reason with no changes at all to the code, I am starting to see errors on the test run:

While upload my app in Google playstore I get this error; We've detected this app uses an unsupported version of Play billing. Please upgrade to Billing Library version 3 or newer to publish this app.

Below are the dependencies on my android studio app, which of them is the billing library to change?
