Having keystore error while migrating project from appybuilder to android studio

Question

I made an app from appybuilder and published it on google play, now I want to release its update that I developed using android studio. Now, I am trying to sign my app with keystore that was generated by appybuilder, but I am getting the error-

Error:Execution failed for task ':app:packageRelease'.

> com.android.ide.common.signing.KeytoolException: Failed to read key 
keystore from store "E:\New folder\Work\android (2).keystore": Keystore was 
tampered with, or password was incorrect. 

help me to fix this error. I know I will not be able to publish its update without the sign of previous release.

when I tried to upload apk without app signing it gives me the error

Upload failed
You uploaded a debuggable APK. For security reasons you need to disable 
debugging before it can be published in Google Play. Learn more about 
debuggable APKs.
You uploaded an APK that is signed with a different certificate to your 
previous APKs. You must use the same certificate. Your existing APKs are 
signed with the certificate(s) with fingerprint(s):
[ SHA1: ****( previous SHA1 key)**** ]
and the certificate(s) used to sign the APK you uploaded have 
fingerprint(s):
[ SHA1: 60:50:E5:C5:6F:DA:4C:13:4E:C4:99:65:E6:13:CA:08:37:BB:55:22 ]

Is there any way to change fingerprint to desired sha1 fingerprint?

Answer 1

at last I found the solution. it was a error for alias, keystore password and key password. when I used the default values for them as

key store password - android

alias - androidkey

key password - android

Hope it will help someone. Thank you everyone.
