Having weakreference doessn't clear it from memory? As application stays long at background? Incase user holds reference and access it via cache?

TinyDB tinyDB = new TinyDB(getApplicationContext());

and later in code accessing after low memory,

tinyDB.getString("username") -> This line will cause nullpointerException
