Question

my question is how much data does Shared Preference take from device? I'm aware Shared Preference is used for small bits of data such as ints, strings etc but how much data does an int take from the device when stored in Shared Preferences? Thanks

There's no hard limit. The main reason it is not recommended to use SharedPreferences in place of the database is mainly the performance -> shared preferences data is keept in ordinary flat XML file which lacks all the features SQLite offers. Also the whole XML file is read into memory so if you grow it too much (but rather MB than KBs) then you may face OutOfMemory on some devices with smaller heap.
