Signing your Android applications
All Android packages (the apk files) are signed by a certificate or a keystore file to enable their installation on a device. When you are debugging/developing your application, your package is automatically signed by a development certificate that was generated by the Android SDK. It is fine to use this certificate for development or even beta testing; however, it cannot be used on an application distributed to Google Play.
To create a production certificate, we can use a command-line tool included with the Android SDK named keytool. To create your own keystore file, run the following line in a terminal window:
keytool -genkey -v -keystore <filename>.keystore -alias <key-name> -keyalg RSA -keysize 2048 -validity ...Get Xamarin: Cross-Platform Mobile Application Development now with the O’Reilly learning platform.
