Receive .vcf file from Files app in Nougat and Oreo versions to my app

Question

I've an Android App, which works fine in Jelly Bean and Kitkat versions. The app will receive .vcf file as Intent from File Manager app using Complete Action Using option.

Now in Android Nougat and Oreo versions, Using Files app, there is an option Open with or Share will not list my App.

How to solve this? Thanks in advance.

Your <intent-filter> elements support http, https, and file. Few "file manager" apps will use any of those on Android 7.0+, in part because the file scheme is banned.

Replace:

        <intent-filter> <!-- Handle intent from a file browser app: -->
            <action android:name="android.intent.action.VIEW" />
            <action android:name="android.intent.action.INSERT_OR_EDIT" />

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

            <data android:scheme="file" />
            <data android:host="*" />
            <data android:mimeType="text/x-vcard" />
        </intent-filter>

with:

        <intent-filter> <!-- Handle intent from a file browser app: -->
            <action android:name="android.intent.action.VIEW" />
            <action android:name="android.intent.action.INSERT_OR_EDIT" />

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

            <data android:scheme="file" />
            <data android:scheme="content" />
            <data android:mimeType="text/x-vcard" />
        </intent-filter>

Then, make sure that readVCard2_1() handles file and content Uri schemes, such as by calling openInputStream() on a ContentResolver to access the stream.
