I have never set any passwords to my keystore and alias, so how are they created?

Question

As I was going through some posts on the Internet learning more about signing your Android app, I got post like how to sign the app, and something

Answer 1

Better than all options, you can set your signingConfig to be equals your debug.signingConfig. To do that you just need to do the following:

android {
  ...
  buildTypes {
    ...
    wantedBuildType {
      signingConfig debug.signingConfig
    }
  }
}

With that you will not need to know where the debug.keystore is, the app will work for all team, even if someone use a different environment.
