Android app gets opened from links sent in email

Question

Our users get emails from time to time to e.g. change their password. When they click the link, I would like to have them sent to our website, but our Android app gets opened.

The link e.g. is https://www.ourdomain.com/change-password/{random-string}.

We do have deep links enabled in our app, but they are configured the following way:

            <intent-filter android:label="...">
            <action android:name="android.intent.action.VIEW" />

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

            <data
                android:host="customhost"
                android:pathPrefix="/"
                android:scheme="https" />

            <data
                android:host="www.ourdomain.com"
                android:pathPrefix="/somethingelse"
                android:scheme="https" />

            <data
                android:host="www.ourdomain.com"
                android:pathPrefix="/againsomethingelse"
                android:scheme="https" />

            <data
                android:host="someothercustomhost"
                android:scheme="https" />

            <data
                android:host="andagainacustomhost"
                android:scheme="https" />
        </intent-filter>

So the change-password part doesn't fit in any of that configurations, what could be the reason our app gets opened nevertheless?

EDIT

it seems as if the problem is the first data-tag; if I comment that out, it behaves as expected (i.e. https://www.ourdomain.com/change-password/1234 is not handled by the app). I don't know why as customhost is a complete different word from www.ourdomain.com...

You may try to separate it into different <intent-filter> components, because with one <intent-filter> application can get confused, even if it is written correctly.

<intent-filter android:label="...">
    <action android:name="android.intent.action.VIEW" />

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

    <data android:host="www.ourdomain.com"
        android:pathPrefix="/somethingelse"
        android:scheme="https" />

    <data android:host="www.ourdomain.com"
        android:pathPrefix="/againsomethingelse"
        android:scheme="https" />
</intent-filter>

<intent-filter android:label="...">
    <action android:name="android.intent.action.VIEW" />

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

    <data android:host="customhost"
        android:pathPrefix="/"
        android:scheme="https" />
</intent-filter>

<intent-filter android:label="...">
    <action android:name="android.intent.action.VIEW" />

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

    <data android:host="someothercustomhost"
        android:scheme="https" />
</intent-filter>

<intent-filter android:label="...">
    <action android:name="android.intent.action.VIEW" />

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

    <data android:host="andagainacustomhost"
        android:scheme="https" />
</intent-filter>
