how to import jks file in visual studio 2019 as existing keystore

I want to update an App on Google Play. I lost the Keystore password, after contacting google support I followed the below-given commands, and they reset the upload key for me.

 1. keytool -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks                 

 2. keytool -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks

Now I have the keystore.jks file. Now here Problem comes.

I am following these steps in Visual Studio 2019.

Right-click on Myproject.Android > Archive then getting apk file Bundle Format: apk

Click Distribute > Google Play > Import

then Import an Existing Keystore dialog box it is expecting with an extension of .keystore file to import but I have .jks tried to convert it to .keystore as well but not succeded.

Here is the error I am getting

   at Xamarin.AndroidTools.PublicationUtilities.KeyManagement.<>c__DisplayClass13_0.<ImportKeyAsync>b__0(Task`1 t) in C:\A\1\34\s\External\androidtools\Xamarin.AndroidTools\PublicationUtilities\KeyManagement.cs:line 313

Is there anything I am missing?

How I can use keystore.jks to update my App?

Solution

  • I thought I should post how I resolved this issue if someone else would be facing this issue he might solve it by following these steps.

    After getting keystore.jks file copy your project.Android.apk and keystore.jks files to C:\Program Files (x86)\Android\android-sdk\build-tools\30.0.2 location.

    run Command Prompt as administrator in given location C:\Program Files (x86)\Android\android-sdk\build-tools\30.0.2

    Now you need to zipalign the apk file manually, run the following commands.

    run zipalign -v -p 4 com.project.Android.apk com.projectAligned.Android.apk

    then you have to sign apk.

    apksigner sign --ks keystore.jks --out com.projectRelease.Android.apk com.projectAligned.Android.apk
