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:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: Mono.AndroidTools.InstallFailedException: The package was not properly signed (NO_CERTIFICATES). /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at Mono.AndroidTools.Internal.AdbOutputParsing.CheckInstallSuccess (System.String output, System.String packageName) [0x000de] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/external/androidtools/Mono.AndroidTools/Internal/AdbOutputParsing.cs:338 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at Mono.AndroidTools.AndroidDevice+<>c__DisplayClass100_0.<InstallPackage>b__0 (System.Threading.Tasks.Task`1[TResult] t) [0x00016] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/external/androidtools/Mono.AndroidTools/AndroidDevice.cs:803 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at System.Threading.Tasks.ContinuationTaskFromResultTask`1[TAntecedentResult].InnerInvoke () [0x00024] in <e068e2227ab74c1bb3d724ebaab0e3ff>:0 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at System.Threading.Tasks.Task.Execute () [0x00000] in /Users/builder/jenkins/workspace/build-package-osx-mono/2020-02/external/bockbuild/builds/mono-x64/external/corert/src/System.Private.CoreLib/src/System/Threading/Tasks/Task.cs:2319 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: --- End of stack trace from previous location where exception was thrown --- /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at AndroidDeviceExtensions.PushAndInstallPackageAsync (Mono.AndroidTools.AndroidDevice device, PushAndInstallCommand command, System.Threading.CancellationToken token) [0x001cf] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/external/androidtools/Xamarin.AndroidTools/Devices/AndroidDeviceExtensions.cs:206 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at AndroidDeviceExtensions.PushAndInstallPackageAsync (Mono.AndroidTools.AndroidDevice device, PushAndInstallCommand command, System.Threading.CancellationToken token) [0x0042f] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/external/androidtools/Xamarin.AndroidTools/Devices/AndroidDeviceExtensions.cs:223 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at Xamarin.Android.Tasks.FastDeploy.InstallPackage (System.Boolean installed) [0x001c0] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/Tasks/FastDeploy.cs:338 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at Xamarin.Android.Tasks.FastDeploy.InstallPackage (System.Boolean installed) [0x0032d] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/Tasks/FastDeploy.cs:355 /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.Debugging.targets(604,5): error ADB0010: at Xamarin.Android.Tasks.FastDeploy.RunTaskAsync () [0x002fb] in /Users/builder/azdo/_work/1/s/xamarin-android/external/monodroid/tools/msbuild/Tasks/FastDeploy.cs:212

DId you also try things like these? https://stackoverflow.com/questions/63530855/xamarin-app-cant-deploy-to-android-11-emulator

I think ultimately this is a problem in your setup and more a Xamarin.Android thing

Thanks for responding-
Yes, I tried that one as well, I'm afraid

This is one of those things that is very hard to debug if there is no reproduction and we can't just sit next to each other to figure it out I guess 😅

I understand-
Luckily on a whim, I checked to see if I had an older debug.keystore to replace the current one with. The current one was a size of 0kb and something was wrong with it.
Doing that fixed it and I can test my Android apps again, so it's all fixed!
Thanks for trying to help- Big fan of your youtube channel, btw.
