Not every app needs cloud storage with a SQLite cache. <\/span><\/h6>\n

I\u2019m going to let you in on a little secret that helps me prototype apps quickly.  Sometimes, when nobody’s looking, I just write my data to disk. I don\u2019t build a cloud backend.  I don\u2019t build a SQLite database. I just serialize my data to JSON and write it to files on the disk.  It\u2019s really easy.<\/span><\/p>\n

There are definitely some drawbacks to this approach, so if your head is about to light on fire with anger towards me, skip to the <\/span><\/i>Caveats<\/i><\/b> section below.<\/span><\/i><\/p>\n

Here\u2019s what it takes; it’s just a couple of lines of Kotlin.  Say I\u2019ve got a FooConfiguration object that I want to persist to disk.  It\u2019s complicated enough that I don\u2019t want to put it in SharedPreferences, so we\u2019re going to write it to a file.<\/span><\/p>\n

Step 1: We have a couple of dependencies to bring in.<\/span><\/p>\n
