如何用gradle执行ionic build android

Answer 1

如何用gradle执行ionic build android –release的时候自动签名

假设android的platform和keystore已经有了，我们可以看到如下目录结构

其中release-signing.properties这个时候应该是没有的，现在我们新建一个release-signing.properties

storeFile=YiShangpu.keystore
key.store.password=your password
key.alias=YiShangpu
key.alias.password=your password

为什么要新建这个文件呢？

可以参考官方的文档https://cordova.apache.org/docs/en/edge/guide_platforms_android_tools.md.html

cdvReleaseSigningPropertiesFile (default: release-signing.properties)

Path to a .properties file that contains signing information for release builds. The file should look like:

storeFile=relative/path/to/keystore.p12
storePassword=SECRET1
storeType=pkcs12
keyAlias=DebugSigningKey
keyPassword=SECRET2

storePassword and keyPassword are optional, and will be prompted for if omitted.

对比我们新建的内容和官方文档是有出入的，那为什么我们的需要用key.store.password这种写法呢？

我们回到项目中，打开build.gradle，找到 addSigningProps。

def addSigningProps(propsFilePath, signingConfig) {
def propsFile = file(propsFilePath)
def props = new Properties()
propsFile.withReader { reader ->
props.load(reader)
}

def storeFile = new File(props.get('key.store') ?: privateHelpers.ensureValueExists(propsFilePath, props, 'storeFile'))
if (!storeFile.isAbsolute()) {
storeFile = RelativePath.parse(true, storeFile.toString()).getFile(propsFile.getParentFile())
}
if (!storeFile.exists()) {
throw new FileNotFoundException('Keystore file does not exist: ' + storeFile.getAbsolutePath())
}
signingConfig.keyAlias = props.get('key.alias') ?: privateHelpers.ensureValueExists(propsFilePath, props, 'keyAlias')
signingConfig.keyPassword = props.get('keyPassword', props.get('key.alias.password', signingConfig.keyPassword))
signingConfig.storeFile = storeFile
signingConfig.storePassword = props.get('storePassword', props.get('key.store.password', signingConfig.storePassword))
def storeType = props.get('storeType', props.get('key.store.type', ''))
if (!storeType) {
def filename = storeFile.getName().toLowerCase();
if (filename.endsWith('.p12') || filename.endsWith('.pfx')) {
storeType = 'pkcs12'
} else {
storeType = signingConfig.storeType // "jks"
}
}
signingConfig.storeType = storeType
}

红色的部分便是原因了。

注意：keystore的路径需要根据实际情况设置。

最后我们执行如下命令即可获得签名后的apk文件。

$ ionic build android —release

your password
