Java - How to create a file on phone using JvDroid?
In Java tutorial, we are taught to work with files on computer. How to work with files on our phone?🤔 I already used JvDroid I have a file named kira.txt in my internal storage. File f= new File("kira.txt") System.out.print( f.exists() ); Why the output is false?

that's an example of my internal storage ;)
in fact internal storage is usually named 'sdcard' (think of it as an unmovable sdcard)
android use linux/unix file system... external sd are mounted to miscelanous directory names under /sdcard/ (could differ related to phone manufacterer...) and could be mounted at different places at same time (different valid path to access same sd/directories)
the simpler and safest to get the path of your file would be to use a file explorator wich could give it to you (almost all decents: I currently use an old version of ES File Explorer, and Total Commander on an old phone)...
on my old phone the paths look like:
/storage/sdCard0/download/file.txt
for internal storage
and
/storage/extSdCard/folder/fike.txt
for external storage

I don't know: maybe it's either a problem of you're not executing the code in the directory containing the file (working directory: may be different of those where the script/executable reside), or a problem related to file permissions: android tends to be very strict about that ;P

something like:
/sdcard/Download/file.txt
absolute path must start with a slash (root is /)
without the starting slash, the path will be relative to the current working directory (folder)

if you run your code in sololearn playground, then it is executed on sololearn servers, so you try to access their local file system, not your phone file system ^^
