How can I read a text file in Android?

I want to read the text from a text file. In the code below, an exception occurs (that means it goes to the

catch
block). I put the text file in the application folder. Where should I put this text file (mani.txt) in order to read it correctly?

try
{
InputStream instream = openFileInput("E:\\test\\src\\com\\test\\mani.txt");
if (instream != null)
{
InputStreamReader inputreader = new InputStreamReader(instream);
BufferedReader buffreader = new BufferedReader(inputreader);
String line,line1 = "";
try
{
while ((line = buffreader.readLine()) != null)
line1+=line;
}catch (Exception e)
{
e.printStackTrace();
}
}
}
catch (Exception e)
{
String error="";
error=e.getMessage();
}

Answer

try this :

i assume your text file is on sd card

    //Find the directory for the SD Card using the API
//*Don't* hardcode "/sdcard"
File sdcard = Environment.getExternalStorageDirectory();

//Get the text file
File file = new File(sdcard,"file.txt");

//Read text from file
StringBuilder text = new StringBuilder();

try {
    BufferedReader br = new BufferedReader(new FileReader(file));
    String line;

    while ((line = br.readLine()) != null) {
        text.append(line);
        text.append('\n');
    }
    br.close();
}
catch (IOException e) {
    //You'll need to add proper error handling here
}

//Find the view by its id
TextView tv = (TextView)findViewById(R.id.text_view);

//Set the text
tv.setText(text.toString());
