How to save data in an android app

Question

I recently coded an Android app. It's just a simple app that allows you to keep score of a basketball game with a few simple counter intervals. I'm getting demand to add a save feature, so you can save your scores and then load them back up. Currently, when you stop the app, your data is lost. So what I was wondering is what I would have to add to have the app save a label (score) and then load it back up. Thanks guys sorry I don't know much about this stuff.

Answer 1

Use SharedPreferences, http://developer.android.com/reference/android/content/SharedPreferences.html

Here's a sample: http://developer.android.com/guide/topics/data/data-storage.html#pref

If the data structure is more complex or the data is large, use an Sqlite database; but for small amount of data and with a very simple data structure, I'd say, SharedPrefs will do and a DB might be overhead.

Answer 2

Please don't forget one thing - Internal Storage data are deleted when you uninstall the app. In some cases it can be "unexpected feature". Then it's good to use external storage.

Google docs about storage - Please look in particular at getExternalStoragePublicDirectory
