How do I save my game with highscores and player positioning in LibGDX?

Question

So I have a game that needs to save high scores for the number of waves, what guns the player has, positioning of the player and the zombies, and so on. I saw something about SharedPreferences but have no clue how to use them. Can someone point me to the right direction or willing to tell me how to use them correctly?

Answer 1

Here how to save your datas with SharedPreferences :

Store data

SharedPreferences sp = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor spe = settings.edit();
spe.putInt("someKey", someIntegerValue);
spe.putFloat("anotherKey", someFloatValue);
spe.commit();

Retrieve data

SharedPreferences sp = getSharedPreferences(PREFS_NAME, 0);
float floatValue = sp.getFloat("anotherKey", defaultFloatValue);
int intValue = sp.getInt("someKey", defaultIntValue);

Where PREFS_NAME is a string containing the name you want for your preference file.

However, SharedPreference is not the only solution, you also can use Internal Storage and SQlite DBs.
