How to file a bug for the AOSP?

this isn't directly a question about android development, but about how to file a bug report if you found a bug within the android OS.
I have seen this documentation link: https://source.android.com/docs/setup/contribute/report-bugs
which finally leads to this bug-tracking system:
https://issuetracker.google.com/issues?q=status:open%20componentid:190923
I created a bug report there, however, after creating it I get an error message saying:
New issue created: 259508180 (view access not granted)
Am I missing something? Thanks in advance for the help!

Xamarin Android error on DeviceInfo.Model

I have a Xamarin for Android app that has been working until today. I needed to make a change but before I did, I ran a test to ensure no VS or Nuget package updates caused an issue. I have Xamarin.Essentials in my app and this line worked before, not sure what is happening now.
if(DeviceInfo.Model == "TC72"){scannerIndex = 1;}
Exception Unhandled:
Xamarin.Essentials.NotImplementedInReferenceAssemblyException: 'This
functionality is not implemented in the portable version of this
assembly. You should reference the NuGet package from your main
application project in order to reference the platform-specific
implementation.'
Any insight would be helpful. TIA

I changed the DeviceInfo.Model to Build.Model and get the same info I was expecting. That fixed my issue. If anyone has a different suggestion, happy to entertain them.
Added 8/11/21 3:25pm CT
I also found that changing my Compile Target to 10.0 fixed the Xamarin.Essentials issues. So far the application is working on 8.1 on the device (Zebra MC3300).

Unable to resolve “expo-app-loading” from “App.js”

I am getting this error:
Failed building JavaScript bundle. Unable to resolve
“expo-app-loading” from “App.js”
when I ran my project after a couple of months. Earlier it was working fine but not now.
Can someone please help me out?

If you recently updated SDK versions (expo upgrade), please be sure to review the breaking changes carefully as is advised when you complete the install.
For instance, SDK-40 which was released in December has breaking changes notes about expo-app-loading that probably addresses what you're seeing perfectly.
Read this page : https://blog.expo.io/expo-sdk-40-is-now-available-d4d73e67da33
Look for section title: AppLoading has been extracted from the expo package

There were two problems:
expo-app-loading was not in my package.json, so I just installed it again and boom, it was in my packege.json then.
I was importing 'AppLoading' the wrong way. I wrote
import {AppLoading} from "expo-app-loading"; //wrong way
Which was breaking. Then I corrected it to
import AppLoading from "expo-app-loading"; //correct way
Which solved the issue.

PhoneGap 2.0 Upgrade Errors - JSCallback Error / Could not find class

I updated my Phonegap (Cordova) project from 1.9 to 2.0 and am receiving the following two new errors:
Web Console
JSCallback Error: Request failed. at file file://android_assets/www/js/cordova-2.0.0.js:3698
and
dalvikvm
Could not find class 'android.webkit.WebResourceResponse', referenced from method org.apache.cordova.CordovaWebViewClient.generatedWebResourceResponse
Is this a known problem? I have searched but can't find a solution that addresses these issues. I have tried creating a new blank project and I am getting the same errors. I have also ensured Eclipse and the SDK manager are up to date.
Any help would be much appreciated.
Thank you.

Not sure about the first question as I need to know what you are doing when that log appears.

App Engine Connected Android Project - Could not find ...RequestFactorySource

I'm unable to run even the default App Engine connected Android app, since updating my SDK. I've gone as far as deleting eclipse and all of my libraries and reinstalling them with no success. I've followed Google's tutorial to the letter and verified the validation tool is in my build path. This is the error I'm getting (and yes requestfactory-client.jar is in my library).
dalvikvm(375): Could not find method com.google.web.bindery.requestfactory.vm.RequestFactorySource.create, referenced from method com.Util.getRequestFactory
dalvikvm(375): VFY: unable to resolve static method 84: Lcom/google/web/bindery/requestfactory/vm/RequestFactorySource;.create (Ljava/lang/Class;)Lcom/google/web/bindery/requestfactory/shared/RequestFactory;
I'm completely lost at this point and about to pull some hair out, please help. Thanks

In my case it's an issue with the new ADT 17 and how it handles library projects. This post is a good explanation on how to fix it:

I, too, was going crazy on this. Hope this helps.
The validation step can be important too (like you did):
