Question

I’m trying to save some data to A file in android, I’m using herefor the internal storage of the android system. I looked it up on the developers guide of android and I came to this.

String FILENAME = "LangFile";
                String data ="NL";
                FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
                fos.write(data.getBytes());
                fos.close();

This is how I save it to the file.

String FILENAME = "LangFile";
        String languege = "lang";
        FileInputStream fos = openFileInput(FILENAME);
        fos.read(languege.getBytes());
        fos.close();
        if(languege=="NL"){
            newgame.setText(R.string.dutchgames);
            stats.setText(R.string.duthstats);
        }

This is how I read from the same file, but if I run it it just gives an empty button?

You can’t compare strings using ==, in fact you need to use either equals or equalsIgnoreCase methods. You also need to tweak your reading logic a little. Change your code as below:

FileInputStream fos = openFileInput(FILENAME);
byte[] b = new byte[2]; //since lang-prefix should have at least length 2
fos.read(b);
fos.close();

if(new String(b).equalsIgnoreCase("NZ")){
     newgame.setText(R.string.dutchgames);
     stats.setText(R.string.duthstats);
}
