Did you build your xamarin.android app before doing the steps in the document? – Quentinquercetin

Hi sorry for the late reply, no I installed visual studio and tried to get SHA-1 signature to first connect the project with firebase. – Danikadanila

Answer 1

Have just encountered this problem. In my case it was with an existing Xamarin Android project on a new machine, new VS2019 install.

The solution:

Create a new Android project, and deploy it to the emulator. This process seemingly creates the keystore.

I just used the template Single View App. Create the new project, select emulator, deploy. It fires up and ... does nothing.

I was then able to return to my real app, and deploy as required.

We're now using Rider and it seems that there's yet another location:

~/Library/Application Support/Xamarin/Mono for Android/debug.keystore

On my machine (which has Android Studio, Visual Studio for Mac and Rider) I have three different Android debug keystores:

• ~/Library/Application Support/Xamarin/Mono for Android/debug.keystore
• ~/.local/share/Xamarin/Mono for Android/debug.keystore
• ~/.android/debug.keystore

maybe you/it changed during install so the path is diffrent?

try browsing your appdata/local folder and see if you can find the xamarin mono map, and then use the whole path directly instead of %LocalAppData%

if you cant find it, or it still doesnt work, try checking the build log when you build in debug, the path for the keystore will be logged in the console during the build process.

This is what it loooks like when i build an example project, in the "deploy to device console"

Signed android package 'bin/Debug/com.project.theProjectName-Signed.apk'

as you can see, on the two last lines in the snippet, it show me that the path for my debug.keystore is "/Users/theusername/.local/share/Xamarin/Mono for Android/debug.keystore"

Hi, I checked and didn't find the Xamarin mono unfortunately the problem was not solved. – Danikadanila

did you find the folder but it did not have the file, or did you not even find the folder? – Troche

i have updated my answer with an example of my log when i build to device with debug, where i can see the path for the keystore file. – Troche

sorry for the late reply , I searched everywhere but the folder Mono for Android does not exist – Danikadanila

Answer 4

I have run into the similiar problem. Please verify if the following path exist with a debug.keystore file:

/Users/theusername/.local/share/Xamarin/Mono for Android/debug.keystore

If it does not exist, create a new solution in Visual Studio and run it. This will create the keystore and you can afterwards return to your original project.
