Cannot open files with FileOpener2, but not getting an error in Android

I am attempting to open a PDF file with FileOpener2 (through ng-cordova) with the following code: 

$cordovaFile.checkFile(cordova.file.dataDirectory, attachmentPath)
    .then((fileEntry) => {
        // success
        fileEntry.getMetadata((metadata) => {
            // metadata.size is in bytes
            var megabyteSize = metadata.size / 1048576;

            if (megabyteSize > 5) {
                var path = cordova.file.dataDirectory + attachmentPath;
                console.log(path); // prints: file:///data/data/com.ionicframework.enhatch146189/files/attachments/CS-353ES_CS-420ES_Eng.pdf which is correct

                $cordovaFileOpener2.open(path, 'application/pdf').then(() => {
                    console.log("Opened!") // prints
                }, (error) => {
                    console.log(error);
                    usePDFJs(); // tries to render PDF in app with PDFJs
                });
            } else {
                usePDFJs();
            }
        })
    }, function (error) {
        // error
        console.error(error);
    });

What happens confuses me: it prompts me with an "open this file in Adobe Reader?" and lists the other PDF viewers, and the console prints "Opened!"

However, no matter what I open ANY pdf in, I get some sort of error such as "cannot open this PDF file".

Can anyone see something wrong with this code?

Apparently, if you use cordova.file.dataDirectory on android you can't open those files in other applications or attach them to emails. Silly mistake -- coded too fast and read too little on the documentation. Using cordova.file.externalApplicationStorageDirectory solved the issue.
