Question

I followed all the steps from generating a key - updating the key.properties with the typed password,

I added link where the key that was created. but still I have problem so I need the solution

Answer 1

Error you got is caused by incorrect path to keystore. Path to this file is determined by storeFile property in android/key.properties. It looks like this:

storePassword=a
keyPassword=b
keyAlias=c
storeFile=../key.jks

Other thing is that this path is not absolute, but relative to android/app/build.gradle. To fix your problem place keystore.jks inside project folder and reference it using relative path.
