Error opening PDF file with fileOpener2 in Ionic 3

Ionic Native
1

I am trying to open a PDF file in my Ionic application and get the following error:

Error opening file Attempt to invoke virtual method ‘android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)’ on a null object reference

What the application does is that it receives a file in base64 format, transforms it to BLOB and then downloads it to the application directory, until this process all goes perfectly, this is the path it writes the file:

file:///data/user/0/io.ionic.starter/files/Informativo%202019_10_20%20e%2021

Then you run File Opener to open and the error pops:

this.file.writeFile(this.file.dataDirectory, fileName, DataBlob, contentType).then((success) => {  
        console.log("File Writed Successfully", success);
        //Method showing error below
        this.fileOpener.open(success.toURL(), this.contentType)
            .then(() => console.log('File is opened'))
            .catch(e => console.log('Error opening file', e));
    }).catch((err) => {  
        console.log("Error Occured While Writing File", err);
    });

I also have this file that I saw in other similar questions: opener_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- https://developer.android.com/reference/android/support/v4/content/FileProvider.html#SpecifyFiles -->

    <!-- cordova.file.externalRootDirectory -->
    <external-path name="external" path="." />
</paths>

My AndroidManifest.xml:

Did you find a fix for this?
Just noticed this today. I was doing a fix for cleartText which URL are allowed.
Hope you can help!
