即时应用程序的单独清单

Question

我可以为免安装应用程序和常规应用程序使用不同的清单吗？
更详细地说，我需要在 "android:name=App" 字段（应用程序标签）中指定不同的类 "App"。

Answer 1

为了帮助您开始，这里是 github 关于免安装应用程序的示例代码。您可以检查以下代码的结构：

    <application

            android:label="@string/app_name"
            android:theme="@style/AppTheme"
            android:supportsRtl="true">

        <activity
                android:name=".HelloActivity"
                android:label="@string/title_activity_hello">

            <intent-filter
                    android:autoVerify="true"
                    android:order="1">

                <category android:name="android.intent.category.BROWSABLE" />
                <category android:name="android.intent.category.DEFAULT" />

                <data android:scheme="https" />
                <data android:scheme="http" />
                <data android:host="hello.instantappsample.com" />

            <meta-data
                    android:name="default-url"
                    android:value="https://hello.instantappsample.com/hello" />
        </activity>
        <activity
                android:name=".GoodbyeActivity"
                android:label="@string/title_activity_goodbye">
            <intent-filter
                    android:autoVerify="true"
                    android:order="2">

                <data android:scheme="https" />
                <data android:scheme="http" />
                <data android:host="hello.instantappsample.com" />
                <data android:pathPrefix="/goodbye" />
            </intent-filter>
        </activity>

    </application>
</manifest>

这里是 Manifest file structure 可以帮助您在构建阶段进一步发展。

The code snippet below shows the general structure of the manifest file and every element that it can contain. Each element, along with all of its attributes, is fully documented in a separate file.

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

<manifest>

    <uses-permission />
    <permission />
    <permission-tree />
    <permission-group />
    <instrumentation />
    <uses-sdk />
    <uses-configuration />  
    <uses-feature />  
    <supports-screens />  
    <compatible-screens />  
    <supports-gl-texture />  

    <application>

        <activity>
            <intent-filter>
                <action />
                <category />
                <data />
            </intent-filter>
            <meta-data />
        </activity>

        <activity-alias>
            <intent-filter> . . . </intent-filter>
            <meta-data />
        </activity-alias>

        <service>
            <intent-filter> . . . </intent-filter>
            <meta-data/>
        </service>

        <receiver>
            <intent-filter> . . . </intent-filter>
            <meta-data />
        </receiver>

        <provider>
            <grant-uri-permission />
            <meta-data />
            <path-permission />
        </provider>

        <uses-library />

    </application>

</manifest>

Answer 2

有几种方法可以做到这一点：

如果您必须有两个不同的清单，那么您将需要使用 tools:replace，示例：

您安装的应用程序模块的清单：

<application
    android:name="com.example.App"
    tools:replace="android:name"/>

您的功能模块清单：

<application
    android:name="com.example.feature.AppFeat">

构建安装型应用时，它将运行和 App，而构建免安装应用时，它将运行和 AppFeat。你可以玩这个的变体。

但是，如果您使用 isInstantApp() 分支，在一个应用程序实现中会更容易。
