How to generate signed and unsigned APK's using gradle?

Question

I need to generate both unsigned and signed release apks using gradle command line (gradlew assembleRelease is the command im using now)

The apks must be aligned. I checked this: Build Unsigned APK with Gradle but it seems to be an old way to achieve this, now it does not work and something has changed in lastest versions of android and gradle compilation. And also i need to generate both apks at same time, not only release mode or unsigned mode

I know it's pretty old answer but it still might help someone gain your goal without adding extra flavour (even as in my case it might be challenging because many dependencies in the project).

android {
  signingConfigs {
    release { ... }
  }

  productFlavors {
    signed { 
      signingConfig (checkUnsigned() ? null : signingConfigs.release)

    }
}

def checkUnsigned ()  {
    return project.hasProperty("unsigned")
}

In order to use it just use

gradle assembleRelease

or

gradle assembleRelease '-Punsigned'

for creating unsigned (quotes for CI, otherwise it might not be needed)

Disadvantage of the solution is just when you want to assemble several flavours in one line ie

gradle assembleRelease assembleDebug assembleRelease '-Punsigned'

assembleRelease checks all properties in command line, so first assembleRelease will be callse also with param '-Punsigned' I resolved this CI issue by using 2 commands - one for signed, other for unsigned versions

gradle assembleRelease assembleOtherFlavour '-Punsigned'
gradle assembleDebug assembleRelease assembleOtherFlavour
