Cordova Android


Example

Step 1: Go to root directory of project and open command line prompt

 cordova build --release android

This generates an unsigned apk under \platforms\android\build\outputs\apk with the name

android-release-unsigned.apk

Step 2: Key generation for obtaining signed apk

Syntax:

 keytool -genkey -v -keystore <keystoreName>.keystore -alias <Keystore AliasName> -keyalg <Key algorithm> -keysize <Key size> -validity <Key Validity in Days>

Example:

keytool -genkey -v -keystore ExampleApp.keystore -alias TestExampleApp -keyalg RSA -keysize 2048 -validity 10000


keystore password? : xxxxxxx
What is your first and last name? :  xxxxxx
What is the name of your organizational unit? :  xxxxxxxx
What is the name of your organization? :  xxxxxxxxx
What is the name of your City or Locality? :  xxxxxxx
What is the name of your State or Province? :  xxxxx
What is the two-letter country code for this unit? :  xxx

The keystore is generated in the same folder with the name ExampleApp.keystore

Step 3: Move the generated keystore to \platforms\android\build\outputs\apk

Run the jarsigner tool in the command prompt under \platforms\android\build\outputs\apk

Syntax:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore <keystorename <Unsigned APK file> <Keystore Alias name>   

Example:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ExampleApp.keystore android-release-unsigned.apk TestExampleApp

This generates the signed apk with the same name.

Step 4: zip align tool to optimize the APK

 zipalign -v 4 android-release-unsigned.apk android.apk

The zipalign is located under \Android\sdk\build-tools\23.0.3\zipalign

This generates a signed apk with the name android.apk which can now be uploaded to app store
