@jgw96 though you have closed the issue. I would really appreciate if you could please just share some information. I am following this post to automatically sign my apk. https://baxeico.wordpress.com/2015/05/20/how-to-automatically-sign-your-android-apk-using-ionic-framework-and-crosswalk/ After that I use zip align tool to optimize the APK. As per the docs (https://developer.android.com/studio/command-line/zipalign.html) it really matters when the zipalign is perform whether before signing or after signing apk. And that depends on the signing tool using to sign. For apksigner, zipalign must only be performed before the APK file has been signed. For jarsigner, zipalign must only be performed after the APK file has been signed.

Can you please share, does automatic apk signing process described in above post also perform zipalign? If not can you please guide which apk signing tool is use in case of automatic signing apk signer or jarsigner.

Thanks for posting! Unfortunately this is not an Ionic issue but instead a support question regarding distributing apps on google play. I would recommend going to our forum and asking around on there. There are a bunch of awesome devs on our forum who will be able to help you. Thanks for using Ionic!
