1. 生成一个签名密钥
可以用keytool命令生成一个私有密钥。在Windows上keytool命令放在JDK的bin目录中（比如C:\Program Files\Java\jdkx.x.x_x\bin），你可能需要在命令行中先进入那个目录才能执行此命令。
$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
2. 创建key.properties文件（your_project/android/key.properties）
#创建KEY时输入的密钥库密码
storePassword=666666
#创建KEY时输入的密钥密码
keyPassword=666666
#密钥名称[默认是key，这里我设置为my-key-alias]
keyAlias=my-key-alias
#签名的存放路径【我把生成的my-release-key.keystore文件扔到了d盘】
storeFile=D:/my-release-key.keystore
3. 修改your_project/android/app/build.gradle
...
def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
android {
...
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
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.debug
signingConfig signingConfigs.release
}
}
}
4. 生成apk
$ flutter build apk
生成的
app-release.apk在项目的your_project/build/output/apk/release目录下
5. 安装
$ adb install app-release.apk
