Its possible update app without reinstall but replacing the storage files?

i am trying to do that. its possible or no?. thanks for help.

What exactly do you want to achieve? What would "replacing the storage files" mean (what effect will it have when you do it)?

i would like to replace images and txt files inside the original storage. its possible that?

its for not change the size of app only modify the storage files for using other files like photos or other kind of files.


Assuming you know the name of the file you've stored, you can overwrite the file by saving a file with the same name, just with a different Text attribute.

Note that you can only save to the external storage and ASD on a non-rooted phone. Saving to and reading from external storage requires the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions (from the link at the top of this post).
If your phone is rooted, you cannot modify the internal storage with your app.

the reason about my question is i would like to replace video files mp4. i know that is not possible make that. only reinstalling can replace the videofiles
