Unable to open keystore in AndroidStudio - "Redundant length bytes found"

I also got the same error and I fixed it by following Solution 1 below. you can try Solution 1 to resolve it. Else follow the other Solutions.

Solution 1

Updating JDK from 7 to 8

You can run the following command to list the content of your keystore file:

keytool -list -keystore .keystore

If you are looking for a specific alias, you can also specify it in the command:

keytool -list -keystore .keystore -alias foo

If the alias is not found, it will display an exception:

 keytool error: java.lang.Exception: Alias does not exist

In order to get all the details I had to add the -v option

keytool -v -list -keystore <FileName>.keystore

It will surely help you to solve the error or you can get the contents of your keystore and can generate a new keystore of your app.
