This is a step that should only be performed However, this keystore is not recognized as a valid keystore for theįor this reason, a private keystore must be created and used for The emulator or to devices configured to use debuggable applications.

Xamarin.Android application, as Android will not run applications thatĭuring development, Xamarin.Android uses a debug keystore to sign theĪpplication, which allows the application to be deployed directly to Create a Private KeystoreĪ keystore is a database of security certificates that is createdįrom the Java SDK.

It assumes that an APK has already beenĪpplications that are built using an older version of the Android SDKīuild Tools must use jarsigner as described in This guide will focus on using apksigner from the Android SDK build If it is necessary to use jarsigner to sign the APK, then it is important to first sign the APK and then run zipalign.

When using apksigner, it is important to first zipalign the application, and then to sign it with apksigner. The order of the steps is important and is dependent on which tool used to sign the APK. Both of these tools will be discussed in more detail below. Applications that are developed with older versions of the Android SDK build tools prior to v24.0.3 will use the jarsigner app from the JDK. Sign the APK – This step involves using the apksigner utility from the Android SDK and signing the APK with the private key that was created in the previous step. Xamarin.Android conductsĪ check at runtime, and will not allow the application to run if More efficiently with the APK at runtime. Zipalign the APK – Zipalign is an optimization process A private key is necessary to digitally sign the APK.Īfter the private key has been prepared, this step can be skipped The following steps are involved with signing an APK:Ĭreate a Private Key – This step needs to be performed This process is typically handled with the IDE, however there are some situations where it is necessary to sign the APK manually, at the command line. After the application has been built for release, the APK must be signed prior to distribution so that it can be run on an Android device.
