The Android Keystore system lets you store cryptographic keys in a container to make it more difficult to extract from the device. Once keys are in the keystore, they can be used for cryptographic operations with the key material remaining non-exportable.

Can Android use same keystore?

yes, you can use the same keystore to sign multiple apks, without a problem. You can also use the same alias (each alias is a certificate) to sign multiple apks, and it will work.
