Glide fails to load resources when trying to load an audio file from smartphone

Problems

Messages in Logcat I'm getting from Android Studio:

I didn't understand those error messages. Why I'm getting then exactly?

Idea

Hello, I am developing an app that records an audio from smartphone, get this audio recorded and transforms it into a byte array vector. The audio after recording is saved by the smartphone as an audio file named "...audio_record.3gp".

What I'm doing: After using the app to record the audio, I open the app called "File Manager" and go to file "/storage/emulated/0" where the audios recorded with end "..audio_record.3gp" are being saved.

To get this local "path" I'm coding this:

String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+UUID.randomUUID().toString()+"audio_record.3gp";

Then I get this audio file and converts it into a bytes array vector doing this:

public byte[] convert(String path) throws IOException {

    FileInputStream fis = new FileInputStream(path);
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    byte[] b = new byte[1024];

    for (int readNum; (readNum = fis.read(b)) != -1; ) {
        bos.write(b, 0, readNum);
    }

    byte[] bytes = bos.toByteArray();

    String decode = Arrays.toString(bytes);
    Log.d("mytag", decode);

    return bytes;

The audio is being recorded correctly, and saved to the file "/storage/emulated/0". The problem happens when we get the last audio from this file and try to work with it.
