Android 深层链接在我链接的应用程序中打开，而不是启动我的应用程序的单独实例

Question

我正在使用 native react 。深度链接非常适合 ios。然而，对于 Android，我似乎无法弄清楚如何从深层链接正确打开我的应用程序。

从例如打开深层链接时Firefox，我的应用程序在 Firefox 窗口内启动。当我使用深度链接测试器应用程序时也是如此。除了不是从正确的应用程序启动之外，该应用程序的一切都按预期工作。

我究竟做错了什么？这是我的 AndroidManifest.xml 的摘录:

    <activity 
         android:name=".MainActivity"
         android:label="@string/app_name"
         android:configChanges=
             "keyboard|keyboardHidden|orientation|screenSize" 
         android:windowSoftInputMode="adjustResize"  
         android:exported="true">
      <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="myapp" />
      </intent-filter>
    </activity>

看看https://developer.android.com/guide/components/activities/tasks-and-back-stack

When declaring an activity in your manifest file, you can specify how the activity should associate with a task using the element's launchMode attribute.

The launchMode attribute specifies an instruction on how the activity should be launched into a task. There are four different launch modes you can assign to the launchMode attribute:

试试把 android:launchMode="singleTask"在您的 Activity 标签上

The system creates a new task and instantiates the activity at the root of the new task. However, if an instance of the activity already exists in a separate task, the system routes the intent to the existing instance through a call to its onNewIntent() method, rather than creating a new instance. Only one instance of the activity can exist at a time.
