You have two options, and I’ll leave selection up to you.
-
Shared Preferences
This is a framework unique to Android that allows you to store primitive values (such as
int
,boolean,
andString
, although strictly speakingString
isn’t a primitive) in a key-value framework. This means that you give a value a name, say, “homeScore” and store the value to this key.SharedPreferences settings = getApplicationContext().getSharedPreferences(PREFS_NAME, 0); SharedPreferences.Editor editor = settings.edit(); editor.putInt("homeScore", YOUR_HOME_SCORE); // Apply the edits! editor.apply(); // Get from the SharedPreferences SharedPreferences settings = getApplicationContext().getSharedPreferences(PREFS_NAME, 0); int homeScore = settings.getInt("homeScore", 0);

Internal Storage
This, in my opinion, is what you might be looking for. You can store anything you want to a file, so this gives you more flexibility. However, the process can be trickier because everything will be stored as bytes, and that means you have to be careful to keep your read and write processes working together.
int homeScore; byte[] homeScoreBytes; homeScoreBytes[0] = (byte) homeScore; homeScoreBytes[1] = (byte) (homeScore >> 8); //you can probably skip these two homeScoreBytes[2] = (byte) (homeScore >> 16); //lines, because I've never seen a //basketball score above 128, it's //such a rare occurance. FileOutputStream outputStream = getApplicationContext().openFileOutput(FILENAME, Context.MODE_PRIVATE); outputStream.write(homeScoreBytes); outputStream.close();
Now, you can also look into External Storage, but I don’t recommend that in this particular case, because the external storage might not be there later. (Note that if you pick this, it requires a permission)
