The size of the text-file is 560 kilobytes and has about 24500 rows. Each row is added to a list. Maybe my phone is to old and slow? Phone-model: Samsung GT-S5570 with Android 2.3.4.
It takes about 30 seconds or more to read it and I'm pretty sure that my algorithms outside the RowReader-class is not the problem. Anyone else who has encountered a similar problem?
