为每个 Build Variant 使用不同的 manifestPlaceholder

Using a different manifestPlaceholder for each Build Variant(为每个 Build Variant 使用不同的 manifestPlaceholder)

本文介绍了为每个 Build Variant 使用不同的 manifestPlaceholder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

我首先要说我对 Gradle 很陌生,所以如果这个问题已经得到解答,我深表歉意.

I will start by saying that I am very new to Gradle, so I apologize if this has already been answered.

我正在开发一个使用 API 密钥访问第三方工具的 Android 应用程序.根据应用的flavor构建类型,需要使用不同的 API 密钥.

I'm working on an Android application that uses an API key to access a 3rd party tool. A different API key needs to be used depending on both the flavor and build type of the app.

这是我正在尝试做的基本概述:

Here is a basic outline of what I'm trying to do:

android {
    defaultConfig {
        manifestPlaceholders = [ apiKey:"DEBUG_KEY" ]
    }

    buildTypes{
        debug{
            // Some debug setup
        }
        release{
            // Some release setup
        }
    }

    productFlavors {
        // List of flavor options
    }
    productFlavors.all{ flavor->
        if (flavor.name.equals("someFlavor")) {
            if (buildType.equals("release")) {
                manifestPlaceholders = [ apiKey:"RELEASE_KEY_1" ]
            } else {
                manifestPlaceholders = [ apiKey:"DEBUG_KEY" ]
            }
        } else {
            if (buildType.equals("release")) {
                manifestPlaceholders = [ apiKey:"RELEASE_KEY_2" ]
            } else {
                manifestPlaceholders = [ apiKey:"DEBUG_KEY" ]
            }    
        }
    }
}

到目前为止,manifestPlaceholders 语句在一个非常简单的情况下工作,但我不知道如何从 productFlavors 中引用 buildTypestrong> 块,以便我可以将其用作条件.

So far the manifestPlaceholders statement is working in a very simple case, but I don't know how to reference the buildType from within the productFlavors block so that I can use it as a conditional.

推荐答案

我猜你指的是Fabric ApiKey?:) 我只是花了几个小时尝试以类似的方式使用占位符并在 gradle 文件中指定 ApiKey,尽管从 com.android.tools.build:gradle:1.3.1.可以为特定风味指定占位符,但不能为风味和 buildType 指定占位符.

I would guess that you are referring to Fabric ApiKey? :) I just spent hours trying to do it in a similar way with the placeholders and specifying the ApiKey in the gradle file although it does not seem possible as of com.android.tools.build:gradle:1.3.1. It is possible to specify a placeholder for a specific flavor but not for a flavor AND buildType.

只是为了纠正你的语法,你必须这样做(如果可能的话)将是类似的,但 manifestPlaceholders 对于变体是未知的.

Just to correct your syntax, the way you would have to do it (if it was possible) would be something like that but manifestPlaceholders are unknown to variants.

applicationVariants.all{ variant->
    if (variant.productFlavors.get(0).name.equals("someFlavor")) {
        if (variant.buildType.name.equals("release")) {
            manifestPlaceholders = [ apiKey:"RELEASE_KEY_1" ]
        } else {
            manifestPlaceholders = [ apiKey:"DEBUG_KEY" ]
        }
    } else {
        if (variant.buildType.name.equals("release")) {
            manifestPlaceholders = [ apiKey:"RELEASE_KEY_2" ]
        } else {
            manifestPlaceholders = [ apiKey:"DEBUG_KEY" ]
        }    
    }
}

您真正需要做的是将密钥保留在 AndroidManifest.xml 中并使用多个清单文件处理它

What you actually need to do is to keep the key in the AndroidManifest.xml and handle it with multiple manifest file

src/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools">    
    <application>    
        <meta-data
            android:name="io.fabric.ApiKey"
            android:value="DEBUG_KEY" tools:replace="android:value"/>
    </application>    
</manifest>

src/someFlavorRelease/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools">    
    <application>    
        <meta-data
            android:name="io.fabric.ApiKey"
            android:value="RELEASE_KEY_1" tools:replace="android:value"/>
    </application>    
</manifest>

src/someOtherFlavorRelease/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools">    
    <application>    
        <meta-data
            android:name="io.fabric.ApiKey"
            android:value="RELEASE_KEY_2" tools:replace="android:value"/>
    </application>    
</manifest>

manifestMerger 将处理替换,您最终将在每个场景中获得正确的密钥.我刚刚成功实施.我只是希望你真的指的是 Fabric 密钥!:)

The manifestMerger will handle the replacement and you will end up with the proper key in every scenario. I just implemented it successfully. I just hope you were really referring to the Fabric key! :)

希望这会有所帮助!
