Trying to write a byte[] to a file, which i think is working correctly
String filename = "BF.dat";
public void WriteByteToFile(byte[] mybytes, String filename){
try {
FileOutputStream FOS = openFileOutput(filename, MODE_PRIVATE);
FOS.write(mybytes);
FOS.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Then later in the app I need to read the bytes back into a byte[]
String filename = "BF.dat"
public byte[] ReadByteFromFile (String filename){
byte[] mybytes = null;
try {
File file = new File(filename);
FileInputStream FIS = new FileInputStream(file);
mybytes = new byte[(int)file.length()];
FIS.read(mybytes);
FIS.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return mybytes;
}
The bytes are not being returned from this, (it works in normal java - but not with the android apk) I'm not sure what I need to make it work in android. There are lots of example of writing bytes to files but I can't find any that explain how to get them back.
If anything is to vague please comment and I will explain more if required.
