title: is there a maximum size to android internal storage allocated for an app?
body: <p>I want to save a json file with all the application data (something similar to preference) but im not sure what is the limit size, because if the app cant use this file it will not function probably. is this information known beforehand and the OS reserve some space for your app or its based on the size available. </p>
  
  <p>Update: 
  I dont really care about External storage since is not always available in the device and could be changed (SD card) and i could check for <a href="https://stackoverflow.com/questions/2652935/android-internal-phone-storage">internal storage using this</a> but this is not what i want to know, What i want to know if there's a memory size allocated for internal storage for the device ? </p>
