Question

I am using this code:

File myDir = new File(getApplicationContext().getFilesDir().getAbsolutePath());
try {                
    Log.i("CSV Testing ", "CSV file creating");
    FileWriter fw = new FileWriter(myDir + "/myfile.csv");
    //
                 // write data to file
                 //   
    Log.i("CSV Testing ", "CSV file created and your data has been saved");
    // Process for sending email with CSV file
    File CSVFile = new File(myDir,"myfile.csv");
    // And sending it with email attachment
} catch (IOException e) {
    Log.i("ExportCSV Exception", e.toString());
}

But it sends myfile.csv as a blank file. I checked it from file explorer, where myfile.csv is not blank and contains right data. How can I solve this?

My Logcat messages are

I/CSV Testing (16920): CSV file creating
I/CSV Testing (16920): CSV file created and your data has been saved

Answer 1

If really is this the case, your path to file must be missing somewhere, means your path to the file must be incorrect.

And because of this, the statement File CSVFile = new File(myDir,"myfile.csv");must be creating new empty file on that location.
