Exception when running instrumented tests with Hilt and App Startup

I am starting to setup some instrumented tests on my project, but when I run them, I get the following exception on logcat:

My real codebase is much more complex, but I created a much simpler project where I am able to reproduce the issue HERE.
From what I understood, when running the instrumentation tests, the startup code is first executed, even before anything on the test class (before #Before and #BeforeClass methods).
What is the best way to handle this?

Need Help Diagnosing why Kivy Android App Crashes on Launch

I've developed a KivyMD app which runs fine on my Windows machine. However, my company has locked down all my USB ports, so I'm not able to "deploy" the app for testing with Buildozer. Instead, I'm using Android Studio to emulate Android. I'm able to install my APK file (produced with Buildozer) on the virtual device, but when I launch the app I only see a Kivy splash screen which says "Loading..." for a second and then it crashes.
Android Studio provides the following log, but as far as I can tell it offers no clue to what the problem is.

How can I get address information using latitude and longitude?

I made this tutorial for get user's address and location but I got error when I changed AVD's location. When I didn't call getCityName function at getLastLocation function, I can get user's location but when I call it, it gave that error. How can I solve it?
it was give an error which was :

Edit:
I tried real device, location services working well I can get city name, street name etc. But in simulator it was give error again. I tried to change AVD's location after that it was going to crash. I believe solution is simple but I don't know how can I search this situation.

Try run the operation in a new Thread, and then if I need to update some UI view I'll do it on runOnUiThread.

React Native app crashing at startup on Android: Didn't find class "com.facebook.react.devsupport.DevSupportManagerImpl"

I am using React Native v 0.62.2 and I am trying to get my project running on Android as well. Up until now, I had focussed development on iOS and therefore did never run the Android app. Now I wanted to run the android app but the app crashes on startup right after the splash screen was shown with the following stacktrace:

I searched the web for solutions or at least hints but did unfortunately not find any solution or even any idea of what could be done to fix this issue.
Does anyone have any idea? Also please let me know if you need any further information in order to be able to answer the question.
Thanks a lot!

For all who are struggling with this issue as well - after a long period of research plus try and error, I got it finally fixed.
It seems that this issue actually is correlated to OK HTTP. The steps that made me get it running were the following:
Enable MultiDex but also keep attention on going for the AndroidX solution (as I use the latest version of React Native which already leverages AndroidX) as stated in the following answer:
https://stackoverflow.com/a/56875424/9055450
Follow the instructions given in the following comment adding ProGuard files: https://github.com/facebook/react-native/issues/9043#issuecomment-298832659

Ionic Capacitor firebase push notification, error:Default FirebaseApp is not initialized in this process

I am new to Capacitor and have migrating my Cordova project to Capacitor.
I trying to get my notification messages working. Therefore i followed the steps shown in
https://capacitor.ionicframework.com/docs/guides/push-notifications-firebase/
Once i build my project, i am opening the project and Android Studio starts. I preform a run, and the app the starts to get downloaded on to my phone, which i then run.
And i get this error message shown below when it comes registering my phone for notification messages.
Am i missing a step?
The google-services.json is also placed in Andriod-->App
Thanks

I had the same problem. In my case I forgot to put google-services.json in android/app folder.
Verify:
google-services.json be in android/app folder and your Android package name should match the appId from your capacitor.config.json file.
We used com.mydomain.myappname for this Capacitor app ID, so that is what we’ll use for this entry.
capacitor.config.json has PushNotifications setup:
{
...
"plugins": {
"SplashScreen": {
...
},
"PushNotifications": {
"presentationOptions": ["badge", "sound", "alert"]
}
},
...
}
Then build your js project and sync.
npx cap sync android
npx cap open android
And build your Android app or test in an emulator.
