How to write to the File ?

Hi All,

I would like to know how to write to file. I have tried using

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
OutPutStream out = new FileOutPutStream(fileName);
 
out.write(byte [], 0, length);
 
Parsed in 0.029 seconds,  using GeSHi 1.0.8.4

This way always returns Parent directory or File is not writable.

Help me out! Does anyone knows what this error is about and how it can be removed.

InputStream is = getYourInputForFileHere();
 
// openFileOutput is called from context. Read more about access levels
 
FileOutputStream out = openFileOutput("myfile.myext",
 
                Context.MODE_PRIVATE);
 
            byte buf[]=new byte[1024];
 
            int len;
 
            while((len=is.read(buf))>0)
 
                out.write(buf,0,len);
 
            out.flush();
 
            out.close();
 
            is.close();

The file will be stored in the specific directory. "data/files" I think.

Hi,

The way you suggested works if the file is being written in the same class that extends Activity class. But if one wants to write the file in different class then it was a problem. So I have written a code that writes to sdcard rather than data/files.

I hope that sdcard would be available in all of the Android Handsets.

Thanks anyways.

No problem. You could just provide your current activity to your class.
And I actually not sure, but there maybe are ways to call it some other way.
