Android Question Writing data to a file

[brodmuehler]

Hi
I want to write data to a file every second. It should also be possible to interrupt the data flow and then restart it again without loosing the existing data, meaning that new data will just be added to the existing file.
Could someone perhaps advise what the best concept would be to do this?
Thanks a lot. Kind regards Rene

you can use a textstream to write to a file. If you open the file in append-mode, the data will be added to the existing file (see http://www.b4x.com/android/help/files.html#textwriter). Alternativly you can use a sqllite database to save your data (see https://www.b4x.com/android/forum/threads/sql-tutorial.6736/)

Great. Will give it a try but seems to be what I need. Thanks a lot. René

Make sure to call TextWriter.Flush if it is important that data will not be lost in case of a crash.
