8. 打包

加上首頁啟動 icon

• 準備一張 1024X1024 的圖檔
• 到app icon網站自動產生需要的icon檔 https://appicon.co/
• 把檔案放到以下的資料夾 <app dir>/android/app/src/main/res/

App 金鑰

• Mac

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

• Windows

  keytool -genkey -v -keystore ./key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias key

• 在 android 資料夾中制作一個 <app dir>\android\key.properties 檔案

  storePassword=密碼
  keyPassword=密碼
  keyAlias=key
  storeFile=../../key.jks

•  編輯 <app dir>\android\app\build.gradle 檔

  略
  
  def keystoreProperties = new Properties()
  def keystorePropertiesFile = rootProject.file('key.properties')
  if (keystorePropertiesFile.exists()) {
      keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
  }
  android {
      略
  
      defaultConfig {
          略
      }
  
      signingConfigs {
          release {
              keyAlias keystoreProperties['keyAlias']
              keyPassword keystoreProperties['keyPassword']
              storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
              storePassword keystoreProperties['storePassword']
          }
      }
  
      buildTypes {
          release {
              // TODO: Add your own signing config for the release build.
              // Signing with the debug keys for now, so `flutter run --release` works.
              signingConfig signingConfigs.release
          }
      }
  }

   

•  到<app dir>/android/app/src/main/AndroidManifest.xml修改app 顯示名稱

編譯 APK 檔

flutter build apk --split-per-abi --target-platform android-arm,android-arm64,android-x64
