I added provider in the manifest before for storing images in my app and now for opening pdf I had to make other provider here is the manifest file This provider is for image saving

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.example.jpegtopdf.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
    </provider>

And this is for opening pdf

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.example.jpegtopdf.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>

This is provider_paths xml file

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path name="external_files" path="."/>
</paths>

This is how I tried to open pdf through intent

val file = File(Environment.DIRECTORY_DOWNLOADS+"/Pdf_list","invoice.pdf")
val intent = Intent(Intent.ACTION_VIEW)
intent.flags = Intent.FLAG_ACTIVITY_NO_HISTORY
Intent.FLAG_ACTIVITY_NEW_TASK
val uri = FileProvider.getUriForFile(this, "com.example.jpegtopdf" + 
".fileprovider",file)
intent.setDataAndType(uri, "application/pdf")
intent.flags=Intent.FLAG_GRANT_READ_URI_PERMISSION
intent.flags=Intent.FLAG_GRANT_WRITE_URI_PERMISSION
this.startActivity(intent)

The file I want to open is in Download/Pdf_list/file_name
