Question

I want to serialize an object and store it inside sdcard under my project name but I’m getting FileNotFoundException.

My code is written below:

FileOutputStream fileOutputStream = null;
ObjectOutputStream objectOutputStream = null;

File dir = new File(Environment.getExternalStorageDirectory(), FILE_LOCATION + username);

try {
    if(!dir.exists()) {
        dir.mkdirs();
    }
    File file = new File(dir, FILE_NAME);
    fileOutputStream = new FileOutputStream(file);
    objectOutputStream = new ObjectOutputStream(fileOutputStream);
    objectOutputStream.writeObject(formList);
    objectOutputStream.close();
} catch(IOException ioException) {
    ioException.getMessage();
} catch (Exception e) {
    e.getMessage();
}

What is the reason for this issue?
I’m running in emulator and my application is in android 3.0.

I suspect your filename is invalid, maybe that . in the directory? Or the file-name its self.
