有条件地将元数据包含在Android清单文件中 [英] Conditionally include meta-data in Android manifest file

问题描述

是否可以根据Gradle中设置的值在Android清单文件中有条件地包含meta-data元素.我能够执行以下操作(在build.gradle中使用resValue设置<some_value>)，但无法找到方法来包含/排除完整的meta-data元素.

Is there way to conditionally include meta-data element in Android manifest file based on value set in Gradle. I am able to do following (using resValue to set <some_value> in build.gradle) but haven't been able to find way to include/exclude complete meta-data element.

    <meta-data
        android:name="<some_setting>"
        android:value="@string/<some_value>" />

推荐答案

某种程度上，但我能够解决此问题的唯一方法是在build.gradle(我在具有不同构建风格的情况下使用了此功能，但并不依赖于此)...我认为围绕清单合并可以做一些其他的聪明事，这也将使它变得更干净. myFlag来自我作为Fastlane脚本一部分传递的project.hasProperty()值

Somewhat of a hack but only way I've been able to address this is by having something like following (have changed names in example) in build.gradle (am using this in context of having different build flavors as well but isn't dependent on that)...I think there's probably some additional smarts that can be done around manifest merging that would make this a bit cleaner as well. myFlag is coming from a project.hasProperty() value I'm passing in as part of Fastlane script

        sourceSets {
            flavor1 {
                if (myFlag == "true") {
                    manifest.srcFile "src/flavor1_flag/AndroidManifest.xml"
                } else {
                    manifest.srcFile "src/flavor1/AndroidManifest.xml"
                }
            }
        }
