Most basic activities can be frozen in the datastore by implementing the write_file() method within the main activity class. This method is then called by sugar to save the activity when it is closed or when user or program commands request that the activity be saved to the datastore. Once saved, the activity can be accessed and reloaded from the journal. | Most basic activities can be frozen in the datastore by implementing the write_file() method within the main activity class.
