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
