Can´t find stored file with Android Studio

Question

I am trying to save a file in my Android app so that I can access it using a file explorer. Since I couldn´t do this, I created a simpler app in which I only create a file and save it to see where is it stored. But I can´t see it no matter the way I do this.

Here is my code:

        Calendar calendar = Calendar.getInstance();
        String myFormat = "dd-MM-yyyy";
        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.FRANCE);
        String today = sdf.format(calendar.getTime());

        //Obtiene ruta de sdcard
        File pathToExternalStorage = Environment.getExternalStorageDirectory();
        //agrega directorio /myFiles
        File appDirectory = new File(pathToExternalStorage.getAbsolutePath() + "/biciMAPS/");
        if ( !appDirectory.exists() ) {
            if ( !appDirectory.mkdirs()) {
                Toast.makeText(MainActivity.this, "could not create directory: " + appDirectory.getAbsolutePath(), Toast.LENGTH_LONG).show();
                return;
            }
        }
        //Crea archivo
        File saveFilePath = new File(appDirectory, today + ".csv");
        Log.i("AAARCHIVOOO", saveFilePath.getAbsolutePath());
        

And this is what the Log.i shows:

I/AAARCHIVOOO: /storage/emulated/0/biciMAPS/24-09-2020.csv

I have used the ES File Explorer and I have noticed that /storage/emulated/0 is referred to the internal storage, but I can´t find the biciMAPS folder.

Any idea?

Thank you!

/storage/emulated/0 is actually /data/media in the file-system.

Likely you have to create the file with saveFilePath.createNewFile() .

And maybe also put some content into it.
