I save a number from a apk in a file but i want dont delete file when i uninstall apk.

Then save and read it like this:

/madhi

This will save the file to the root of your sdcard (/sdcard/emulated/0) which will survive an uninstallation of the app

hi ,when i reinstall app ,can not find file.i use noxplayer emulator.

The root directory of the External Storage is:
/storage/emulated/0/ or
file:///storage/emulated/0/ or
file:///mnt/sdcard/

See here:

Did you change:

mahdi

to

/madhi

(note the forward slash before the word madhi)
