下面是解决签名不一致的问题 解决方案
keytool -genkey -v -keystore ./key.jks -keyalg RSA -keysize 2048 -validity 20000 -alias HL
很多会遇到 原因是keytool 是java的库 需要配置java环境 或者 在java目录下进行操作
bash: keytool: command not found
在java环境目录 打开cmd 执行后 复制key.jks 到你的安卓目录下 (android/)
在安卓目录下(android/) 新增key.properties 文件
写入 密码是你自己设置的密码
storePassword789asd
keyPassword789asd
keyAliasLH
storeFile../key.jks
最后在你 (android/app) 下的build.gradle 配置 buildTypes
// 最上面
def keystorePropertiesFile rootProject.file(key.properties)
def keystoreProperties new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))//签名信息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.debuggable falseminifyEnabled true// signingConfig signingConfigs.debugsigningConfig signingConfigs.releasendk{ // 必须加入这部分否则可能导致编译成功的release包在真机中会闪退abiFilters armeabi-v7a}}debug {ndk {//这里要加上否则debug包会出问题,后面三个为可选x86建议加上不然部分模拟器回报错abiFilters armeabi, armeabi-v7a, arm64-v8a, x86}}}
flutter build apk --release
这样就解决了升级遇到的签名版本不一致的问题
