Android构建gradle文件版本号自动递增

Question

如何在每次获取发布包时自动增加 android 构建 gradle 文件中的版本号

Answer 1

You can add Version details in the version.properties file. But, I recommended you can update the version code and version number manual because each time you build it increased by one. One more thing with that if you want to release a major update then you also need to update manually. In conclusion, the manually update version provides more controls on your updates.

compileSdkVersion 25
buildToolsVersion "25.0.2"

def versionPropsFile = file('version.properties')

if (versionPropsFile.canRead()) {
    def Properties versionProps = new Properties()

    versionProps.load(new FileInputStream(versionPropsFile))
    def name = versionProps['VERSION_NAME']
    def code = versionProps['VERSION_CODE'].toInteger() + 1
    versionProps['VERSION_CODE']=code.toString()
    versionProps.store(versionPropsFile.newWriter(), null)

    defaultConfig {
        applicationId "com.bsupits.example.autoincrement"
        versionName name
        versionCode code
        minSdkVersion 15
        targetSdkVersion 25
    }
}
else {
    throw new GradleException("Could not read version.properties!")
}
