How to utilize Firebase both in Flutter as well as native android within the same project? I have a project in flutter that relies on Firebase for authentication, db, and functions. However, I have a receiver class that extends BroadcastReceiver and runs in the background, on the android side of my application. Within this receiver class I utilize Firestore, Analytics, Auth and Cloud_Functions. Given this unique android setup, I need to instantiate the following dependencies in my app level build.gradle file: implementation 'com.google.firebasefirebase firestore24.3.1'...

Android Kotlin function with multiple optional parameters, call function only with parameters at specific place So I have this function that has 8 optional parameters (yes I know it's bad practice to have that much, this is legacy code :D).

Appropriate use of coroutines for parallel API calls I'm trying to learn the right way to use Kotlin coroutines to do some parallel API calls. I've been able to get the expected results/process, but am wondering if there is a "more correct" way to do so. Here's my contrived example of what I'm trying to do. Use case is essentially an inbound web request, and that request in turn needing to make a couple of API calls. Digging around led me to using launch or async: // using launch var recordExists = false var otherRecordExists = false...

JPA entity mapping for performance I have a Parent table which usually has less than 10 child records. So I am fine with EAGER fetch and don't need filtering/pagination/etc. In this case, a bidirectional mapping is recommended as it will have better performance compared to a unidirectional mapping. Correct? This is the kotlin code below. Is this considered as a bidirectional mapping because I used the mappedBy field even though I did not explicitly mention the @ManyToOne annotation in child class? SQL: create table employee (...

Android Bitmap pixels become slightly rectangular for larger width/height ratios I am working on a pixel art editor for Android, and I noticed that when I create Bitmaps with more obscure width/height ratios, for example 3x300 or 5x90 (or the other way round) the pixels become slightly rectangular. I've tried for a week or two to find out what exactly I am doing 'wrong' with the sizing calculations, but I have no idea how to fix this issue. This issue is not recreatable when creating Bitmaps with similar width/height ratios. Below is the code that handles the sizing of...

ActivityThread.handleStartActivity crash happening in release variant What is the crash? This is specifically happening in release version of the app. I can see the logs in Crashlytics, and this is one of the early crash which happens as soon as the user is opening the app. Also, this happens only uniquely once for very small group of users who all are on Android 12 with Samsung Devices. What have I tried so far? To be honest, I'm clueless as to why this might be happening. I think the suspect might be a condition on launcher activity that decides whether to...
