flutter admob issues on m1 mac for android

Admob for Android emulator IPixel_2_API_S:5554) hangs a lot with errors/warnings. It looks like something to do with com.google.android.gms.chimera, which I believe is connected to Firebase.
I'm not using Firebase, so I shouldn't be getting Firebase issues, it would seem...
I've updated everything I can think of: xcode, flutter, android studio (to m1 mac version)(I'm using vscode for development), sdks, and emulators. I also removed the gem pod (1.10.x) and installed the newer version using homebrew (1.11.3). (that helped a lot, actually - prior to that it didn't work at all...)
This is on an m1 Air with 16gb of memory and 500gb ssd, mostly empty - I don't think I'm running into resource issues.
Here's the initialization debug output:

It eventually shows the ad after three more long hangs, and then brings up a banner: 'Google Play Store Keeps Stopping' (don't know how that got into the act...)
It works great for the IOS emulator - no issues, no hangs, no warnings, no errors.
It also works fine (for android) on a Linux dev environment (Fedora), so that's a workaround until this gets fixed.

Why Android Volley library is unable to connect asp.net web api?

I am trying to call asp.net web api from Android Client using Volley library. The .net API is working fine and listening ports are:
http://localhost:5000 and https://localhost:5001 in my local machine.
But,When, I try to run android client keeping the base url as http://10.0.2.2:5000/api/login
I found below error in console->

New Android App failing on repeated launch

I'm running through this tutorial on building an android app with google maps built in. The first run I made was successful, but when I run the same thing successively, it crashes and cannot load.
Included here are the log for the successful run, and from the unsuccessful run:
- a non-exiting runtime exception
- the fatal unimplemented / null object reference exception
- a log about accessing hidden fields that's much longer than the equivalent message in the "correct" log
I'm unsure about what data is necessary, but there's a size limit on these questions, so let me know if there's any other info that could be helpful here.
Successful Launch:

From what is seems in the Fatal Exception where it reads
java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference
at line 4, you try to get the width of a drawable which is loaded to null (probably an ImageView not defined (correctly) in the xml file).
Can you verify that all Views are defined correctly?

DeviceClient error when it calls method open

I'm using this sample code for Android from this page.
Just replaced the content of connstring from line 29 with "Hostname=<myHostname>.azureiotcentral.com;DeviceId=<myDevice>;SharedAccessKey=<myPrimaryKey>";
I'm using SAS Authentication.
The first error is when it tries to call client.open() (line 138).
It's giving me the following error each time when it's trying sending messages (line 122).
Connected to process 20170 on device '7.3_Foldable_API_30 [emulator-5554]'.

What protocol are you using? Is that a MQTT? Also please check the version of the device client are you using.
Second thing that you can do is to try on a different device and see if the issue persists. at time certain devices do exhibit issues like this.

At the end I tried this library. It works.

Emulators can't load "libGLES_emulation" driver

I am in the process of setting up FirebaseUI using Google's guide but I suddenly got an error I can't seem to find a solution for. I'm pretty sure it has to do with my gradle, because I've tried commenting changes in my Java files, using my phone instead of an AVD, and other emulators to no avail. I've included what I got in the Run console, Manifest, and gradles. If you need more information, please let me know. Thanks!
EDIT: For those with the same issue, I think I fixed it by updating Google Play services on the API Q emulator (you have to sign in to Google Play first), then I added the following to the app-level gradle:
android {
...
compileOptions {
...
sourceCompatibility = 1.8
targetCompatibility = 1.8
...
}
...
}
I don't know how it worked, but I hope it does for you too.
