Deploying the App

Android Deployment

1. Generate Keystore

   keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload

2. Configure Keystore Create/update android/key.properties:

   storePassword=<password>
   keyPassword=<password>
   keyAlias=upload
   storeFile=<path to keystore>

3. Update build.gradle In android/app/build.gradle:

   def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
   
   android {
       signingConfigs {
           release {
               keyAlias keystoreProperties['keyAlias']
               keyPassword keystoreProperties['keyPassword']
               storeFile file(keystoreProperties['storeFile'])
               storePassword keystoreProperties['storePassword']
           }
       }
   }

4. Build Release APK
