flutter 配置安卓的签名

背景

最近遇到一个需求，需要实现app的热更新,了解了一下热更新方案时间的时间有点久，就做了个app升级的过渡版本，然后遇到问题真机安装遇到签名不一致的问题

如下

安装过程

版本升级的代码如下

 ///版本更新检查static Future<VersionEntity> checkVersionUpdate() async {if (isWeb) {return VersionEntity(need: false);}PackageInfo packageInfo = await PackageInfo.fromPlatform();String version = packageInfo.version;// String jsonStr = await rootBundle.loadString('assets/json/version.json');// Map<String, dynamic> jsonData = json.decode(jsonStr);Map<String, dynamic> jsonData = await getVersion();VersionEntity versionEntity = VersionEntity.fromJson(jsonData);Version latestVersion = Version.parse(versionEntity.version ?? version);Version currentVersion = Version.parse(version);print(1);if (latestVersion > currentVersion) {_toUpdate(versionEntity);} else {return VersionEntity(need: false);}/// 非强制更新// if (versionEntity.data!.need! && !(versionEntity.data!.necessary!)) {//   _toUpdate(versionEntity);// } // 强制更新// else if (versionEntity.data!.need! && versionEntity.data!.necessary!) {//   _toUpdate(versionEntity);// } else {//   // KLogUtil.d('无需更新');// }return versionEntity;}///版本更新弹窗static _toUpdate(VersionEntity versionEntity) {// 进度String progress = '';double downloadProgress = 0.0;bool downloadStart = false;// 禁止返回bool disBack = versionEntity.necessary!;Get.bottomSheet(isDismissible: !(versionEntity.necessary!),enableDrag: !(versionEntity.necessary!),StatefulBuilder(builder: (context, state) {String fileAddress = '';return WillPopScope(onWillPop: () => _onBackPressed(disBack),child: AppToast.bottomSheetContainer(padding: EdgeInsets.fromLTRB(20.w, 5.h, 20.w, 20.h),height: 429.h,bgColor: const Color(0xFF25272B),child: Column(children: [Container(width: 36.w,height: 4.h,decoration: BoxDecoration(color: versionEntity.necessary!?

}

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

storePassword=789asd
keyPassword=789asd
keyAlias=LH
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"}}}
