How to read file from phone's internal memory in android?

Question

I have downloaded a file from HttpConnection using the FileOutputStream in android and now its being written in phone's internal memory on path as i found it in File Explorer

/data/data/com.example.packagename/files/123.ics

Now, I want to open & read the file content from phone's internal memory to UI. I tried to do it by using the FileInputStream, I have given just filename with extension to open it but I am not sure how to mention the file path for file in internal memory,as it forces the application to close.

Any suggestions?

Answer 1

If the file is where you say it is, and your application is com.example.packagename, then calling openFileInput("123.ics"); will return you a FileInputStream on the file in question.

Or, call getFilesDir() to get a File object pointing to /data/data/com.example.packagename/files, and work from there.

Answer 2

This is what i am doing

try

{

FileInputStream fileIn;
fileIn = openFileInput("123.ics");

InputStream in = null;

EditText Userid = (EditText) findViewById(R.id.user_id);

byte[] buffer = new byte[1024]; int len = 0;

while ( (len = in.read(buffer)) > 0 )
{
Userid.setText(fileIn.read(buffer, 0, len)); }

fileIn.close();

} catch (FileNotFoundException e)

{ e.printStackTrace(); }

catch (IOException e)

{
e.printStackTrace(); }

@rob where are you initializing InputStream? as from your code I can see that it is set to null.
