I got the above error message while trying to access the file from Internal Storage using openFileInput("/Dir/data.txt") method with subdirectory Dir. The reason is that you cannot access subdirectories using this method, just try something like,
FileInputStream fIS = new FileInputStream (new File("/Dir/data.txt"));
Code Snippet:try {
FileInputStream fIS = new FileInputStream (new File(fileName));
InputStreamReader isr = new InputStreamReader(fIS, "UTF-8");
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
text.append(line + '\n');
}
br.close();
fIS.close();
} catch (IOException e) {
Log.e("C2c", "Error occured while reading text file!!");
}
