Good afternoon. I have an application, I used to sign the following signature key:
keytool -genkey -v -keystore mykeystore.keystore -alias aliasname -keyalg RSA -validity 999999.
The key was created, but an error occurred at the end:
Warning:The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using “keytool -importkeystore -srckeystore mykeystore.keystore -destkeystore mykeystore.keystore -deststoretype pkcs12”. ( I do not know how to fix it)
Next, the app compiles perfectly, but when you try to install it on your device, it doesn’t open! I thought it was because it’s not in the Play Market, but when I uploaded it there, the error persisted. Maybe something is wrong with the key or with java. I really hope for your help!
