Without code its a bit hard to answer. how do you get the path?

File pathDir = Environment.getExternalStorageDirectory();

should do it ... dont use the .toString() method

I agree with LogicWorX..Some code would be very handy. Here is another snippet that will help you out when guarding against the external storage not being available:

String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
// We can read and write the media
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
// We can only read the media
} else {
// Something else is wrong. It may be one of many other states, but
// all we need to know is we can neither read nor write
}

Another helpful snippet:

File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
// Make sure the Pictures directory exists.
path.mkdirs();

the Environment class has other directories available as well in the class as constants.

Hi,
This is the code i'm using for stroring the file in memory;

if (Environment.MEDIA_MOUNTED.equals(state)) {
mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
mExternalStorageAvailable = true;
mExternalStorageWriteable = false;
} else {
mExternalStorageAvailable = mExternalStorageWriteable = false;
}

if (mExternalStorageAvailable && mExternalStorageWriteable) {
String PATH = Environment.getExternalStorageDirectory()+ "/download/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "update.apk");
if (outputFile.exists()) {
Log.d("11111", "delete");
outputFile.delete();
}
FileOutputStream fos = new FileOutputStream(outputFile);
