Android Question write file option

[mirekk36]

I have maybe basic android question.

Is that possible to write some file (string into file) but if there isn't external SD card and I will that this file will not be deleteted when I uninstall my application .. It can be useful for me if I can write some string to some android log , some cache folder etc

I need to read this file (string) just if I do new installation of my application

I need to know if user of my demo application try to uninstall and then install the same demo application.

Or? ... maybe is another solution to check if my application was unninstaled just before installing (I need check such situation)

Save it under File.DirRootExternal or in a custom subfolder.

File.DirRootExternal is on the internal SDCard.
