【生成Release apk】
1、使用Java SDK中的keytool生成keystore。
Java SDK一般位于：C:\Program Files\Java\jdkx.x.x_x\bin.
$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
Note: Remember to keep your keystore file private and never commit it to version control.
2、将前一步生成的 my-release-key.keystore 放置到 android/app。
3、新建 ~/.gradle/gradle.properties（~为用户目录，如 C:\Users\xxx\）
MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=*****
MYAPP_RELEASE_KEY_PASSWORD=*****
4、编辑 android/app/build.gradle
...
android {
...
defaultConfig { ... }
signingConfigs {
release {
if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
storeFile file(MYAPP_RELEASE_STORE_FILE)
storePassword MYAPP_RELEASE_STORE_PASSWORD
keyAlias MYAPP_RELEASE_KEY_ALIAS
keyPassword MYAPP_RELEASE_KEY_PASSWORD
}
}
}
buildTypes {
release {
...
signingConfig signingConfigs.release
}
}
}
...
----------------------通过以上4步，就完成了生成release apk的所有配置-----------------
5、生成 release apk
cd android && ./gradlew assembleRelease
生成的apk位于:android/app/build/outputs/apk/app-release.apk
