I tried to save data from my own class to File! My class is

odmiana

The code looks like that:

od = new odmiana(e1.getText().toString(),e2.getText().toString(),e3.getText().toString(),e4.getText().toString(),e5.getText().toString(),e6.getText().toString());
String filename = "myfile";
FileOutputStream outputStream;

try {
    outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
    outputStream.write(od);
    outputStream.close();
} catch (Exception e) {
    e.printStackTrace();
}

Can you help me?

but it actually isn`t String, it`s my own class – Jakub Lelek Dec 08 '17 at 15:59

You need to use an `ObjectOutputStream`. what does `openFileOutput` do? – BackSlash Dec 08 '17 at 16:00
