I also encountered this problem recently, although see the problem seems to be a long time ago, but the hope can help people search,
Also has not been updated in my file, but also has the same size, always 20 KB, finally I accidentally put the file save as to the default address, found after opening is right, before has been saved to the desktop (in order to easy to find), the results before the open is always only a message,

Write a check SQLite data classes, can put the data in the form of a log printed or displayed in TextView in the Activity

I also encountered this problem,
Inside the Device File Explorer data - data - com. Xx, xx of the corresponding directory inside the databases to check the database only 4 KB,
If directly to save it as the computer desktop to see what all have no,

Need to save the whole databases folder as to the default path, usually on the local document - androidstudio folder inside, and then find the corresponding to the db files, open, you can see the data, I am using SQLite Expert Personal 5 this software
