問題描述

我已設(shè)置 Gradle 以將包名稱后綴添加到我的調(diào)試應(yīng)用程序中，這樣我就可以在一部手機(jī)上擁有我正在使用的發(fā)布版本和調(diào)試版本.我引用了這個(gè):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"
        }
    }
}

在我開始在我的應(yīng)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]

我了解這是因?yàn)閮蓚€(gè)應(yīng)用(發(fā)布和調(diào)試)正在注冊(cè)相同的 ContentProvider 權(quán)限.

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

我看到了解決這個(gè)問題的一種可能性.如果我理解正確，您應(yīng)該能夠在構(gòu)建時(shí)指定要使用的不同文件.然后我應(yīng)該能夠?qū)⒉煌臋?quán)限放在不同的資源文件中(并且從清單設(shè)置權(quán)限作為字符串資源)并告訴 Gradle 使用不同的資源進(jìn)行調(diào)試構(gòu)建.那可能嗎?如果是，那么任何關(guān)于如何實(shí)現(xiàn)這一目標(biāo)的提示都會(huì)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!

或者也許可以使用 Gradle 直接修改 Manifest?任何其他關(guān)于如何在一臺(tái)設(shè)備上運(yùn)行與 ContentProvider 相同的應(yīng)用程序的解決方案都是受歡迎的.

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.

推薦答案

沒有一個(gè)現(xiàn)有的答案讓我滿意，但是 Liberty 很接近.所以這就是我的做法.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 測(cè)試版 0.8.2
• Gradle 插件 0.12.+
• Gradle 1.12

我的目標(biāo)是使用相同的 ContentProvider 在同一設(shè)備上運(yùn)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.

在您的應(yīng)用集后綴的 build.gradle 中用于調(diào)試構(gòu)建:

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

buildTypes {
    debug {
        applicationIdSuffix ".debug"
    }
}

在 AndroidManifest.xml 文件中設(shè)置 ContentProvider 的 android:authorities 屬性:

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 中設(shè)置 AUTHORITY 屬性，該屬性可在您的實(shí)施中需要時(shí)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

我將再次從我當(dāng)前的設(shè)置開始:

Once again I will start with my current setup:

• Android Studio 測(cè)試版 0.9.2
• Gradle 插件 0.14.1
• Gradle 2.1

基本上，如果您需要為不同的構(gòu)建自定義一些值，您可以從 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 從 BuildConfig.java 類中訪問它
• 使用 resValue 從資源中訪問它，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

作為資源的替代方案，您可以創(chuàng)建單獨(dú)的 buildType 或風(fēng)味目錄并覆蓋其中的 XML 或值.但是，我不會(huì)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 文件中添加以下內(nèi)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"'
    }
}

您將在 BuildConfig.java 類中看到結(jié)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 文件中指定的資源

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 中再次使用相同的資源，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:自動(dòng)補(bǔ)全(Ctrl+Space)不適用于這些生成的資源，因此您必須手動(dòng)輸入它們

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