Cordova 5: Building signed Android applications

Even though signing Android applications is quite simpler than signing iOS applications, it’s sometimes annoying to set it up and reliably automate it (without using Phonegap or comparable services). Recently I tried automating singing a Cordova application for Android and struggled finding a reliable documentation.

The official Cordova documentation states, that you can easily append a bunch of arguments to the build command to automatically sign your Android application:

Keystore (--keystore): Path to a binary file which can hold a set of keys.
Keystore password (--storePassword): Password to the keystore
Alias (--alias): The id specifying the private key used for singing.
Password (--password): Password for the private key specified.
Type of the keystore (--keystoreType): pkcs12, jks (Default: auto-detect based on file extension)

The catch is, you need to append these arguments as platformopts (POPTS):

cordova build [PROD] [TARGET] [EXP] [PLATS] [BUILDCONFIG] [-- POPTS]

  PROD:   --debug|--release
  TARGET: --device|--emulator|--target=FOO
  EXP:    --experimental [EXPERIMENTALFLAGS]
  POPTS:  platformopts

Therefore the command to build a signed Cordova android application becomes:

cordova build --release android -- --keystore=my.keystore --storePassword=K3ySt0reP4ssw0rd --alias=foobar --password=K3yP4ssw0rd

Alternatively, you could specify them in a build configuration file (build.json) using (–buildConfig) argument.

     "android": {
         "release": {
             "keystore": "my.keystore",
             "storePassword": "K3ySt0reP4ssw0rd",
             "alias": "foobar",
             "password" : "K3yP4ssw0rd",
             "keystoreType": ""

and respectively

cordova build --release android --buildConfig=buildConfig.json

I tested all those commands with Cordova 5.4.0
