saving in sharedpreferences take a lot of time
<p>in my app to save configurations I do:</p>

<p>((Activity) context).getSharedPreferences("contentList", 0).edit()
                .putString("contentList", contentListString).commit();</p>

<p>((Activity) context).finish();</p>

<p>This takes a lot of time until the activity finishes. Is there a reason for this, and how to improve it?</p>

<p>Thanks, best regards.</p>
