【中文标题】我想创建一个密钥库来签署应用程序,但每次我得到这个错误时说啥?【英文标题】:I want to Create a keystore to Signing the app but everytime m getting this error which says?我想创建一个密钥库来签署应用程序,但每次我得到这个错误时说什么? 【发布时间】:2020-12-20 20:35:35 【问题描述】:出了什么问题: 评估项目 ':app' 时出现问题。
没有方法签名:java.lang.String.isNumber() 适用于参数类型:(整数)值:[1] 可能的解决方案:isNumber()、isInteger()
【问题讨论】:
你能分享你的 build.gradie 应用文件吗? 这里是请检查.... ***.com/a/63693278/12757102 这可能会有所帮助:***.com/questions/57238933/… 【参考方案1】:更改这些行
versionCode flutterVersionCode.isNumber(1)
versionName flutterVersionName "1.0"
到这里:
versionCode 1
versionName "1.0"
或者这个:
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
【讨论】:
【参考方案2】: def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists())
localPropertiesFile.withReader('UTF-8') reader ->
localProperties.load(reader)
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null)
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null)
flutterVersionCode = '1'
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null)
flutterVersionName = '1.0'
