File is not created in SDCARD

Question

I am using this method, found in a lot of questions here in SO:

public void generateNoteOnSD(Context context, String sFileName, String sBody) {
    try {
        File root = new File(Environment.getExternalStorageDirectory()+File.separator+"folder", "AGL");
        if (!root.exists()) {
            root.mkdirs();
        }
        File gpxfile = new File(root, sFileName);
        FileWriter writer = new FileWriter(gpxfile);
        writer.append(sBody);
        writer.flush();
        writer.close();
        if(gpxfile.exists()){
            Toast.makeText(context, "OK", Toast.LENGTH_SHORT).show();
        }else{
            Toast.makeText(context, "KO", Toast.LENGTH_SHORT).show();
        }

        Almacen.setRutaFichero(gpxfile.getAbsolutePath());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

I have this in my AndroidManifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Everything seems to be ok, no exception is thrown, the right Toast is shown in screen...but I go to the folder where the file should be...and its not there. And I am scratching my head, because this very method worked ok a couple of times! I am using a library that writes logs and all...and the files with the logs are there...

Any help?

Creating a file on the SD Card requires the access permission of the `DocumentTree` — Ümañg ßürmån, Nov 15 '18 at 11:11
I am using a API 16 device, and will not run in another device, so no need of that — Fustigador, Nov 15 '18 at 11:46
If you run on APi 23+ then you need `DocumentTree` permission otherwise known as SAF more info [Here](https://developer.android.com/guide/topics/providers/document-provider) — Ümañg ßürmån, Nov 15 '18 at 11:52
Have you debugged that code, from which line its stop executing? — Rujul Gandhi, Nov 15 '18 at 11:52
It is not stopping executing anywhere, it just simply does not create the file... — Fustigador, Nov 15 '18 at 11:52

If the "OK" toast displays, the file has already been created successfully. So why can not see the file?

check Almacen.setRutaFichero(gpxfile.getAbsolutePath()); what does the method do?
go to correct file location, in your case it will be:

manually refresh the folder using mouse
