Well, in that case, let's see the logcat stack trace :)
I have code just like this, and it works on real devices, except I'm
calling it before opening the database, from inside my "db open
helper"-alike. Wonder if that's what's making the difference.

Hi, Kostya.
Hard coding aside (i agree its not the best practice), i have methods
verifying that the paths are indeed correct. I'm uncertain why it
works in eclipse but not on the device

Don't hard code the paths.
For the database path, use context.getDatabasePath
For the sdcard, use Environment.getExternalStorageDirectory

Hi,
I am attempting to copy a file from internal storage like so:
void exportDB() throws IOException {
InputStream input = new FileInputStream("/data/data/
com.drayagerecorder/databases/DB");
// create directory for backup
checkStorage();
File dir = new File("/sdcard/DB");
dir.mkdir();
// Path to the external backup
OutputStream output = new FileOutputStream("/sdcard/DB/"+
currentName +"_db");
// transfer bytes from the Input File to the Output File
byte[] buffer = new byte[1024];
int length;
while ((length = input.read(buffer))>0) {
output.write(buffer, 0, length);
}
It works in eclipse but does not work on the device. Am i accessing
the internal storage correctly? The external storage is checked and is
available
output.flush();
output.close();
input.close();
}
