问题描述

我已设置 Gradle 以将包名称后缀添加到我的调试应用程序中，这样我就可以在一部手机上拥有我正在使用的发布版本和调试版本.我引用了这个:http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Types

I have set up Gradle to add package name suffix to my debug app so I could have release version that I'm using and debug version on one phone. I was referencing this: http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Types

我的 build.gradle 文件如下所示:

My build.gradle file looks like this:

...
android
{
    ...
    buildTypes
    {
        debug
        {
            packageNameSuffix ".debug"
            versionNameSuffix " debug"
        }
    }
}

在我开始在我的应用程序中使用 ContentProvider 之前，一切正常.我明白了:

Everything works fine until I start using a ContentProvider in my app. I get:

Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]

我了解这是因为两个应用(发布和调试)正在注册相同的 ContentProvider 权限.

I understand that this happens because two apps (release and debug) are registering same ContentProvider authority.

我看到了解决这个问题的一种可能性.如果我理解正确，您应该能够在构建时指定要使用的不同文件.然后我应该能够将不同的权限放在不同的资源文件中(并且从清单设置权限作为字符串资源)并告诉 Gradle 使用不同的资源进行调试构建.那可能吗?如果是，那么任何关于如何实现这一目标的提示都会很棒！

I see one possibility to solve this. If I understand correctly, you should be able to specify different files to use when building. Then I should be able to put different authorities in different resource files (and from Manifest set authority as string resource) and tell Gradle to use different resource for debug build. Is that possible? If yes then any hints on how to achieve that would be awesome!

或者也许可以使用 Gradle 直接修改 Manifest?任何其他关于如何在一台设备上运行与 ContentProvider 相同的应用程序的解决方案都是受欢迎的.

Or maybe it's possible to directly modify Manifest using Gradle? Any other solution on how to run same app with ContentProvider on one device is always welcome.

推荐答案

没有一个现有的答案让我满意，但是 Liberty 很接近.所以这就是我的做法.首先，目前我正在使用:

None of existing answers satisfied me, however Liberty was close. So this is how am I doing it. First of all at the moment I am working with:

• Android Studio 测试版 0.8.2
• Gradle 插件 0.12.+
• Gradle 1.12

我的目标是使用相同的 ContentProvider 在同一设备上运行 Debug 版本和 Release 版本.

My goal is to run Debug version along with Release version on the same device using the same ContentProvider.

在您的应用集后缀的 build.gradle 中用于调试构建:

In build.gradle of your app set suffix for Debug build:

buildTypes {
    debug {
        applicationIdSuffix ".debug"
    }
}

在 AndroidManifest.xml 文件中设置 ContentProvider 的 android:authorities 属性:

In AndroidManifest.xml file set android:authorities property of your ContentProvider:

<provider
    android:name="com.example.app.YourProvider"
    android:authorities="${applicationId}.provider"
    android:enabled="true"
    android:exported="false" >
</provider>

在您的 code 中设置 AUTHORITY 属性，该属性可在您的实施中需要时使用:

In your code set AUTHORITY property that can be used wherever needed in your implementation:

public static final String AUTHORITY = BuildConfig.APPLICATION_ID + ".provider";

提示:之前是BuildConfig.PACKAGE_NAME

我将再次从我当前的设置开始:

Once again I will start with my current setup:

• Android Studio 测试版 0.9.2
• Gradle 插件 0.14.1
• Gradle 2.1

基本上，如果您需要为不同的构建自定义一些值，您可以从 build.gradle 文件中完成:

Basically, if you need to customise some values for different builds you can do it from the build.gradle file:

• 使用 buildConfigField 从 BuildConfig.java 类中访问它
• 使用 resValue 从资源中访问它，例如@string/your_value

• use buildConfigField to access it from the BuildConfig.java class
• use resValue to access it from resources e.g. @string/your_value

作为资源的替代方案，您可以创建单独的 buildType 或风味目录并覆盖其中的 XML 或值.但是，我不会在下面的示例中使用它.

As an alternative for resources, you can create separate buildType or flavour directories and override XMLs or values within them. However, I am not going to use it in example below.

在 build.gradle 文件中添加以下内容:

In build.gradle file add the following:

defaultConfig {
    resValue "string", "your_authorities", applicationId + '.provider'
    resValue "string", "account_type", "your.syncadapter.type"
    buildConfigField "String", "ACCOUNT_TYPE", '"your.syncadapter.type"'
}

buildTypes {
    debug {
        applicationIdSuffix ".debug"
        resValue "string", "your_authorities", defaultConfig.applicationId + '.debug.provider'
        resValue "string", "account_type", "your.syncadapter.type.debug"
        buildConfigField "String", "ACCOUNT_TYPE", '"your.syncadapter.type.debug"'
    }
}

您将在 BuildConfig.java 类中看到结果

You will see results in BuildConfig.java class

public static final String ACCOUNT_TYPE = "your.syncadapter.type.debug";

并在 build/generated/res/generated/debug/values/generated.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- Automatically generated file. DO NOT MODIFY -->
    <!-- Values from default config. -->
    <item name="account_type" type="string">your.syncadapter.type.debug</item>
    <item name="authorities" type="string">com.example.app.provider</item>

</resources>

在您的 authenticator.xml 中使用 build.gradle 文件中指定的资源

In your authenticator.xml use resource specified in build.gradle file

<?xml version="1.0" encoding="utf-8"?>
<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
                       android:accountType="@string/account_type"
                       android:icon="@drawable/ic_launcher"
                       android:smallIcon="@drawable/ic_launcher"
                       android:label="@string/app_name"
/>

在您的 syncadapter.xml 中再次使用相同的资源，并且 @string/authorities 也

In your syncadapter.xml use the same resource again and @string/authorities too

<?xml version="1.0" encoding="utf-8"?>
<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android"
              android:contentAuthority="@string/authorities"
              android:accountType="@string/account_type"
              android:userVisible="true"
              android:supportsUploading="false"
              android:allowParallelSyncs="false"
              android:isAlwaysSyncable="true"
        />

提示:自动补全(Ctrl+Space)不适用于这些生成的资源，因此您必须手动输入它们

Tip: autocompletion(Ctrl+Space) does not work for these generated resource so you have to type them manually
