Writing and reading files

Writing and reading files

Nov 14

Been a busy weekend hacking on a project, a bit of Android development and a bit of web development.

Sadly I spent some time just working out how to read and write data to a flat file on Android. So I thought I’d share the code snippet I’m using

public static void WriteSettings(Context context, String data, String file) throws IOException {
	FileOutputStream fos= null;
	OutputStreamWriter osw = null;
	fos= context.openFileOutput(file,Context.MODE_PRIVATE);
	osw = new OutputStreamWriter(fos);
	osw.write(data);
	osw.close();
	fos.close();
}

public static String ReadSettings(Context context, String file) throws IOException {
	FileInputStream fis = null;
	InputStreamReader isr = null;
	String data = null;
	fis = context.openFileInput(file);
	isr = new InputStreamReader(fis);
	char[] inputBuffer = new char[fis.available()];
	isr.read(inputBuffer);
	data = new String(inputBuffer);
	isr.close();
	fis.close();
	return data;
}
