Android my app does not appear in "SEND TO" function

Question

Sorry , but perhaps the title does not understand the question .

I wanted to know , according to you, why with this mainfest

 <activity
            android:name="soget.com.visual.PdfWiever"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" >
                </action>
                <category android:name="android.intent.category.DEFAULT" >
                </category>
                <category android:name="android.intent.category.BROWSABLE" >
                </category>
                <data
                    android:mimeType="application/pdf"
                    android:scheme="file" >
                </data>
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.SEND" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data
                    android:mimeType="application/pdf"
                    android:scheme="file" >
                </data>
            </intent-filter>
        </activity>
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_path" />
        </provider>

in android 7 I see my app in the list of the function SEND To (as image)

But from android version 9 up .... doesn't work. How can I adapt my app to versions higher than android 7.
