app module is given in front process

but I need to deal with it in back process, is there any chance to get the 'userData' Folder's Path, in order to write on it, in Back process?

You can use IPC to share information between front and back process.

You can use IPC to share information between front and back process.

I used that but in Mobile it immediately closes:

// ------- send App Location to back
let path = app.getPath('userData');
front.send ( 'here' , path );

back.on ( 'here' , function (data) { const here = data; } );
answer = Object.assign ( {} , answer_template );
answer[ 'stat' ] = 'looking_in';

directories = fs.readdirSync ( here );
answer[ 'retrieved_data' ] = directories;
back.send ( 'Hey_you' , answer );

You have to read read operations inside the callback function because javascript is async or you can use promise

Did you write this whole thing inside the ipc callback

from androidjs.

Did you write this whole thing inside the ipc callback

this part in front:

// ------- send App Location to back
let path = app.getPath('userData');
front.send ( 'here' , path );

this part in back:

back.on ( 'here' , function (data) { const here = data; } );
answer = Object.assign ( {} , answer_template );
answer[ 'stat' ] = 'looking_in';

fs.readdir ( here , (err, directories ) => {

answer[ 'retrieved_data' ] = directories;
back.send ( 'Hey_you' , answer );

} );

I changed readdirSyc to readdir, but still it closes

You have to write whole dependent code inside the back's callback.

Do you know how javascript works ?

Do you know how javascript works ?

it has been summarized here, it is a part of over 1500 lines of coeds,
this part will be triggered in appropriate time: (it is a tiny part of a function named looker, which will call in later, and if I set the here to /sdcard/www/content it works fine )

answer = Object.assign ( {} , answer_template );
answer[ 'stat' ] = 'looking_in';

Yeah, I am not saying to write whole thung inside the callback but you have to write whole code which are dependent on here inside the callback

from androidjs.

Yeah, I am not saying to write whole thung inside the callback but you have to write whole code which are dependent on here inside the callback

so do you mean this code :

back.on ( 'here' , function (data) { const here = data; } );

will not set here globally?!

No, not at all because of async behaviour of javascript.

so How can I send here to back at the starting of the App and keep here for entire Time and use it as other const vars?

from androidjs.

Not possible to save the value of here because of js async behaviour.
I used the same concept in sample story app, you can check soruce for the reference.
