Kudan sample app not launching - android-studio

I have problem with launching Kudan sample app on my phone. I am using Kudan in Android Studio.
I created project as was described on website, checked is matches bundeID in my app and on the website(I know key wont be working if they are not the same), Studio doesnt show any errors or warning during compilation, but I cant still launch it on my phone.
Anyone any ideas what might cause it?

How to debug a website in Android Studio?

I've suspected for a while that my website doesn't work on Android WebView. Trying to debug this, I've installed Android Studio, and fired up some emulators. Sure enough, my website does not behave properly when viewed in WebView in the emulator.
But, I'm not an app developer, and I've never used Android Studio before. Predictably, all of the docs are focused on creating apps :).
How can I debug what's happening in the WebView? Do I need to create an empty project? Is there some DevTools equivalent? Or maybe some way to dump what it's doing to a log file?
I just need a starting point, and am happy to read docs if I'm pointed in the right direction.

Problem with Android Studio emulator, keep missing (maybe crashing)

I tried to find some solution on StackOverflow but seems like there is no similar problem, I am new to android studio development. The emulator keeps missing after running for a while or I click a few things on the emulator or in my own built application. It is like a crash but does not show any crash messages, the emulator will directly go missing and show this picture below. May I know what's the problem? I tried the solution of wiping all the data on the virtual device, still had the problem
Problem with the emulator
The issue is still not solved yet, but I decided to use React Native with the android studio emulator, it works without crashing.

Flutter not building app without error at all

My Flutter project was working just fine. I lost my Internet connection for a bit and when it came back I got a pop up talking about an Android Configuration found for the project, I clicked Add, then it started showing me two Device slots on the Upper tab where it shows what devices are connected.
Now if I need to run my app on my device, Flutter simply tries to run the project, then stops without any output in the Run Tab of Android Studio. This is really giving me a headache... I wish it gave an error or something. Someone please help me so i can resume development.
if you have not changed anything in the android directory the easiest thing to do is to delete it, then run in the terminal
flutter create .
if you have changed a lot of things in the android you can copy your changes and do the same or can go an revert the gradle configurations manually.

How to fix app emulator on Android Studio

I am using android studio and whenever I try to open the app emulator to view the current app the previous app I was working on comes up instead of the current.
Is there a way to refresh it?
I also haven't been able to find any similar questions online.

How to resolve symbols #mipmap and #style in Flutter project?

A while ago my designed Flutter app was running like it should in simulation (virtual device) in Android Studio. After some updates of both Flutter as Android studio I am not able to get the app in simulation. I am new to Flutter and Android studio (have a little knowledge of Xcode, 2 apps in the store) so I have looked at stackoverflow first to find a solution. All tried suggestions did not worked for me and I am hoping somebody can help me.
I have an original version of the project which was running in simulation mode. Now I am working in a duplicated version to find out how to get things up and running again. It worked before but why does Flutter or Android Studio give an error now? The folders and content do exist. Perhaps it is a simple thing to solve but it is not in my knowledge.
What to do to solve the error message I get as shown in the screendump?
The problem seems to be with the resources,
this should help.
Android Studio error: cannot resolve symbol in Xml
Or try to run "flutter clean" (usually solves many problems)
Flutter studio sometimes does not resolve those (no idea why).
Try opening the same Android project in Android studio and check it from there.
Once back, try File->Invalidate Caches/Restart
If they exist and the name is right (without extension), then it could be it.
