Build Unsigned APK with Gradle

Question

Currently I\'m trying to learn Gradle to build Android APKs. How to set an option in gradle to build an unsigned APK?

Answer 1

To generate an unsigned apk do the following:

• define a signingConfig with empty configuations like this:

  signingConfigs{
      unsigned{
          storePassword = ""
          keyAlias = ""
          keyPassword = ""
      }
  }
  

• define in the buildTypes for your release Version with the unsigned Configuration:

  buildTypes{
      release{
          signingConfig signingConfigs.unsigned
      }
  }
  

I get this from the adt-dev group, where Xavier Ducrohet write:

The current behavior is to check that the signing config is fully configured(*) and if it is, it generates a signed APK, otherwise an unsigned APK.

(*) fully configured right now means the value for store, alias and passwords are present, but does not include that the keystore is present.

As withoutclass mentioned this doesn't work with the gradle plugin version 0.6.3.

Anyway it's possible to generate an unsigned APK with gradle: just let the signingConfig entry of a flavor or buildType empty. It should look like this:

productFlavors{
    // with this config you should get a "MyProject-flavorUnsigned-release-unsigned.apk"
    flavorUnsigned{
        versionCode = 9
        packageName defaultPkgName
    }
}

buildTypes{
    // with this config you should get a "MyProject-release-unsigned.apk"
    release{
        packageNameSuffix '.release'
    }
}
