manifestPlaceholders使用

在build.gradle的多版本中设置

            manifestPlaceholders = ["test_key": "修改的内容"]

好比如下

    productFlavors{
        dev{
            manifestPlaceholders = ["test_key": "测试版key"]
        }
        free{
            applicationIdSuffix ".free"
            manifestPlaceholders = ["test_key": "Free版key"]
        }
    }
