I have a Xamarin Android application that I want to generate a signed APK for using the Azure DevOps build pipeline.
Right now, I receive a java.io.IOException: Invalid keystore format.
I generated the keystore file from the command line with the following command:
keytool.exe -genkeypair -v -keystore myAppName.keystore -alias myAppNamekey -keyalg RSA -keysize 2048 -validity 10000
This keystore works on my local device.
I also tried adding the default debug.keystore file to the azure pipeline, and that works successfully.
I added the key to my (already working) CI build pipeline in Azure DevOps, under the "Signing and Aligning" section.
When it reaches this section, I receive the following error:
Failed to load signer "signer #1" java.io.IOException: Invalid
keystore format
[error]Error: The process 'C:\Program Files (x86)\Android\android-sdk\build-tools\24.0.3\apksigner.bat' failed
with exit code 2

I think I found a solution to this. But I changed two things so it could be either of these things.\n\n\nI had a '!' in my keystore password. I removed that because I saw that their where issues with having special characters. (This is probably not the change that fixed it but I wanted to add this just to be sure)\nI re-generated a key with jdk1.8.0_13 version. This is path to the keytool I used \"C:\\Program Files (x86)\\Java\\jdk1.8.0_131\\jre\\bin\\keytool.exe\" \n\n\nWhen doing these two things the signing task worked. Hope this helps!",
