Android: writing a file to sdcard
- by Sumit M Asok
I'm trying to write a file from an Http post reply to a file on the sdcard.
Everything works fine until the byte array of data is retrieved.
I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest
and tried many different combinations of tutorials I found on the net.
All I could find was using the openFileOutput("",MODE_WORLD_READABLE) method, of the activity
but how my app writes file is by using a thread.
Specifically, a thread is invoked from another thread when a file has to be written,
so giving an activity object didn't work even though I tried it.
The app has come a long way and I cannot change how the app is currently written.
Please, someone help me?
CODE:
File file = new File(bgdmanip.savLocation);
FileOutputStream filecon = null;
filecon = new FileOutputStream(file);
// bgdmanip.savLocation holds the whole files path
byte[] myByte;
myByte = Base64Coder.decode(seReply);
Log.d("myBytes", String.valueOf(myByte));
bos.write(myByte);
filecon.write(myByte);
myvals = x * 11024;
seReply is a string reply from HttpPost response.
the second set of code is looped with reference to x.
the file is created but remains 0 bytes
