Description

(copied from stackoverflow) https://stackoverflow.com/questions/71751365/error-msb6006-java-exited-with-code-2-on-xamarin-android?noredirect=1#comment126818451_71751365

I know this question has been asked several times- My Xamarin Android package builds just fine, and gives me this error- I can't run ANY project (including fresh new projects) on any emulator or my own physical Android- Runs totally fine on IOS. I'm on Mac

I've tried everything I could find online

  • Reinstalling VS 2019

  • Using VS 2022

  • Reinstalling Xamarin and all emulators as well as Java SDKs and Android SDKs

  • Enabling/disabling multidex or Appkey signing with debug.keystore and other custom made keys ( this gives error MSB6006: "java" exited with code 1.) on both debug and release

Sometimes with different parameters, I get "error ADB0010 The package was not properly signed (NO_CERTIFICATES)."

Also not able to find a solution for that

This problem came about after updating an app on google play console, but I don't see why this would have anything to do with it

If anybody could help, it'd be greatly appreciated- I'm completely unable to test my xamarin projects on Android at all and it's driving me crazy.

Edit:
The code that is supposedly the culprit is:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(2309,2)

Which is

<AndroidApkSigner Condition=" '$(AndroidUseApkSigner)' == 'true' "
	ApkSignerJar="$(ApkSignerJar)"
	ApkToSign="%(ApkAbiFilesAligned.Identity)"
	KeyStore="$(_ApkKeyStore)"
	KeyAlias="$(_ApkKeyAlias)"
	KeyPass="$(_ApkKeyPass)"
	StorePass="$(_ApkStorePass)"
	PlatformKey="$(AndroidSigningPlatformKey)"
	PlatformCert="$(AndroidSigningPlatformCert)"
	ToolPath="$(JavaToolPath)"
	ToolExe="$(JavaToolExe)"
	ManifestFile="$(IntermediateOutputPath)android\AndroidManifest.xml"
	AdditionalArguments="$(AndroidApkSignerAdditionalArguments)"
/>

Edit 2:

When ASB00100 shows up here's the error log:
