1. Android Manifest

3. Buat Keystore
Di dalam cmd folder project tulis perintah :
keytool -genkey -v -keystore keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key


4. Reference Keystore

• Buat file android/key.proprerties :

storePassword=<password from previous step>

keyPassword=<password from previous step>

keyAlias=key

storeFile=<location of the key store file, e.g. /Users/<user name>/key.jks>

5. Ubah Gradle

• Buka android/app/build.gradle
• Ubah defaultConfig:

defaultConfig {

   applicationId "id.athalon.hello" //nama package

   minSdkVersion 16

   targetSdkVersion 27

   versionCode 1 //version code

   versionName "1.0" //version code

   testInstrumentationRunner        "android.support.test.runner.AndroidJUnitRunner" }

• Ubah bagian ini :

android {

Menjadi :
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
   keystoreProperties.load(new FileInputStream(keystorePropertiesFile)) 
}
android {

• Ubah bagian ini :

buildTypes {

   release {

      signingConfig signingConfigs.debug

   }

}

Menjadi :
signingConfigs {
   release {
      keyAlias keystoreProperties['keyAlias']
      keyPassword keystoreProperties['keyPassword']
      storeFile file(keystoreProperties['storeFile'])
      storePassword keystoreProperties['storePassword']
   }
}

buildTypes {
   release {
      signingConfig signingConfigs.release
   }
}
