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 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 jsonData = json.decode(jsonStr);
Map 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!;

} 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 false
minifyEnabled true
// signingConfig signingConfigs.debug
signingConfig signingConfigs.release
ndk{ // 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
