整理一些常用的Android Studio中gradle的配置
多个Model统一编译环境
原理很简单,将配置放在一个所有model都可以引用的地方, 在Project的build.gradle添加

文件制定model的versionName/versionCode
model的build.gradle同文件夹下创建文件, 命名为version.properties, 内容:

| versionName = 1.0
versionCode = 1
model的build.gradle中解析version.properties
android {
...
ext.versionFile = file('version.properties')
//动态加载配置文件version.properties里面的属性值
if (!versionFile.exists()) {
throw new GradleException("Required version file does not exist:versionFile.canonicalPath")
}
Properties versionProps = new Properties()
versionFile.withInputStream {
stream -> versionProps.load(stream)
}
def code = versionProps.versionCode.toInteger()
def name = versionProps.versionName
defaultConfig {
...
versionCode code
versionName name
}
}

修改编译后的项目名称, 编译后的名称添加versionName,versionCode, 以及渠道名称

if (outputFile != null && outputFile.name.endsWith('.apk')) {
if (variant.buildType.name == "release") {

}
output.outputFile = new File(outputFile.parent, fileName)
}

| signingConfigs {
debug {
storeFile file("signature/system.jks") //model通文件夹下创建文件夹signature, 放置签名文件
storePassword "****"
keyAlias "****"
keyPassword "*****"
}
release {
...
}
}
buildTypes {
debug {
...
signingConfig signingConfigs.release //应用签名的配置
}

流程 : 配置一个签名的配置—> 在buildTypes中使用签名配置, 签名文件可以在签名打包的时候创建, 如果你的签名文件不是jks, 百度一下转换方法即可
