Hello, I’ve installed the app to google play store. However, when I wanted to open a new version again, I got an application signing error.

I’ve increased the Version code once.
But it didn’t work. Application signing error has exhausted me.

Please help me. I’ve tried many times.

How do I check the format.

As per the post:

keytool -list -keystore [keystore_name]

I’ve been trying for a month. Please help me.
