Windows

For Debug Builds

Locate the Xamarin debug.keystore file that is used to sign the app. By default, the keystore that is used to sign debug versions of a Xamarin.Android application can be found at the following location:

C:\Users\USERNAME\AppData\Local\Xamarin\Mono for Android\debug.keystore

Information about a keystore is obtained by running the keytool.exe command from the JDK. This tool is typically found in the following location:

C:\Program Files (x86)\Java\jdkVERSION\bin\keytool.exe

Add the directory containing keytool.exe to the PATH environment variable. Open a Command Prompt and run keytool.exe using the following command:

keytool.exe -list -v -keystore "%LocalAppData%\Xamarin\Mono for Android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

When run, keytool.exe should output the following text. The MD5: and SHA1: labels identify the respective signatures:

Alias name: androiddebugkey
Creation date: Aug 19, 2014
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[1]:
Owner: CN=Android Debug, O=Android, C=US
Issuer: CN=Android Debug, O=Android, C=US
Serial number: 53f3b126
Valid from: Tue Aug 19 13:18:46 PDT 2014 until: Sun Nov 15 12:18:46 PST 2043
Certificate fingerprints:
         MD5:  27:78:7C:31:64:C2:79:C6:ED:E5:80:51:33:9C:03:57
         SHA1: 00:E5:8B:DA:29:49:9D:FC:1D:DA:E7:EE:EE:1A:8A:C7:85:E7:31:23
         SHA256: 21:0D:73:90:1D:D6:3D:AB:4C:80:4E:C4:A9:CB:97:FF:34:DD:B4:42:FC:
08:13:E0:49:51:65:A6:7C:7C:90:45
         Signature algorithm name: SHA1withRSA
         Version: 3

For Release / Custom Signed Builds

The process for release builds that are signed with a custom .keystore file are the same as above, with the release .keystore file replacing the debug.keystore file that is used by Xamarin.Android. Replace your own values for the keystore password, and alias name from when the release keystore file was created.

When the Visual Studio Distribute wizard is used to sign a Xamarin.Android app, the resulting keystore resides in the following location:

C:\Users\USERNAME\AppData\Local\Xamarin\Mono for Android\alias\alias.keystore

For example, if you followed the steps in Create a Create a New Certificate to create a new signing key, the resulting example keystore resides in the following location:

C:\Users\USERNAME\AppData\Local\Xamarin\Mono for Android\chimp\chimp.keystore

For more information about signing a Xamarin.Android app, see Signing the Android Application Package.

Once you've got the keystore from Xamarin then you can just simply import it by following these instructions.

This is specified in your Gradle build file, copy the keystore file into your Android Studio project structure, I chose to create a new directory under app called keystores: /app/keystores/release.keystore

signingConfigs {
    debug {
        storeFile file('keystores/debug.keystore')
    }
    release {
        storeFile file('keystores/release.keystore')
        keyAlias ...
        storePassword ...
        keyPassword ...
    }
}
buildTypes {
    debug {
        signingConfig signingConfigs.debug
        debuggable true
    }
    release {
        signingConfig signingConfigs.release
        debuggable false
    }
}
