在清单中使用变量

本文介绍了在清单中使用变量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在Android中集成某些库(例如Branch-io)需要在项目清单中定义元数据.其中一些变量类似于TestMode

Integrating some libraries like Branch-io in Android need to define meta-data in project manifest. some of this variable is like TestMode

<meta-data android:name="io.branch.sdk.TestMode" android:value="true" />

因此，当我们要发布应用程序时，应将其更改为False.

So, when we want to publish the application we should change it to False.

有什么方法可以根据BuildType在某处定义变量并将其分配给该变量的元数据吗?

Is there any way to define a variable somewhere according to BuildType and assign it to the Meta-data to that?

推荐答案

您可以通过添加清单占位符到您的 build.gradle 文件:

You can do it by adding manifestPlaceholders to your build.gradle file:

android { ... buildTypes { debug { manifestPlaceholders = [isBranchSdkInTestMode:"true"] ... } release { manifestPlaceholders = [isBranchSdkInTestMode:"false"] ... } } ... }

在 AndroidManifest.xml 中，您可以将其用作${isBranchSdkInTestMode}:

In AndroidManifest.xml, you can use it as ${isBranchSdkInTestMode}:

<meta-data android:name="io.branch.sdk.TestMode" android:value="${isBranchSdkInTestMode}" />
