Can't speak for size limitations, but why are putting the data into a
vector, and appending to EditText one line at a time?
Reading line by line and building the content in a StringBuilder seems
more efficient, then you can do editText.setText() just once.
And reading one line at a time is only necessary if your file comes from
Windows and contains '\r' characters (they are not recognized by
TextView and have to be stripped, leaving just '\n'-s).

What would be the best way of reading large text files from the
sdcard?
Right now I'm using this in my browser activity:
File f = new File(filePath);
FileInputStream file = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(file));
do {
st = in.readLine();
vector.add(st);
} while (st != null);
in.close();
and in the other activity where I want to edit the file I have:
char lf = 10;
int k = 0;
String s = null;
for (int i = 0; i< browseractivity.vector.size(); i++) {
s = browseractivity.vector.get(k);
if (s != null) {
editText.append(s);
editText.append(String.valueOf(lf));
}
k++;
}
When trying this on a file of 24648 bytes which corresponds to 24097
chars on 555 lines
I looked in Notepad++ at which characters it cuts.
It displays 8764 characters which corresponds exactly to 9000 bytes
and 237 lines
Does any one have a better suggestion of how to do this so I can read
larger files?
