I have been developing an application on the HTC desire. It runs fine. The application when a button is clicked downloads a file from the my web server and saves it onto the SD card.
I now want to run this application on my Samsung Galaxy Tab. However, is crashes when i click on the button.
The only reason i can see is that the tab is not allowing access to the SD Card. It is the same SD Card i had in the HTC Deisre phone and it is not write protected or anything?
Anyone know what can be wrong?
This is the code i am using to download a file and store it on the card…
class CreatefilesTask extends AsyncTask<Object, Integer, Boolean> {
protected Boolean doInBackground(Object... arg0) {
try{
URL url = new URL("http://213.143.36.32/file.csv");
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
InputStream is = url.openStream();
File testDirectory =
new File(Environment.getExternalStorageDirectory()+"/File");
if(!testDirectory.exists()){
testDirectory.mkdir();
}
FileOutputStream fos = new FileOutputStream(testDirectory+"/file.csv");
byte data[] = new byte[1024];
int count = 0;
long total = 0;
int progress = 0;
while ((count=is.read(data)) != -1){
total += count;
int progress_temp = (int)total*100/lenghtOfFile;
if(progress_temp%10 == 0 && progress != progress_temp){
progress = progress_temp;
}
fos.write(data, 0, count);
}
is.close();
fos.close();
}
catch(Exception e){
e.printStackTrace();
}
This works fine on the Desire.

Found the answer!
On the Galaxy tab the storage is not only /sdcard it is /sdcard/external_sd/
