FileNotFoundException open failed: ENOENT (No such file or directory)

Question

I have a file called "and.doc" that has big number of records each one has this shape

expression : defenition ;

So I'm trying to

• Read the file with scanner
• use ; as a delimiter
• find a way to split expression from definition
• and somehow add them to my Sqlite Database (if someone have any idea how to do that it will be great).

I'm using this code

    try {


  mf =new File("/home/agh/AndroidStudioProjects/Dicod/app/src/main/res/raw/and.doc");
        inputFile = new Scanner(mf);
        inputFile.useDelimiter(";");
        while (inputFile.hasNext())
        {
            String x = inputFile.next();
            Toast.makeText(getApplicationContext(),x,Toast.LENGTH_LONG).show();

       //Splitting and adding to the databse

        }


    }

    catch(FileNotFoundException e) {
        e.printStackTrace();
    }`

But I keep getting this error

Answer 1

Maybe the file doesn't exist in the selected directory or the READ_EXTERNAL_STORAGE permission is not granted.

Notice that if you target API 23, you have to request for permission on runtime, not only in the Manifest.
