File Reading

[Artem Kolesnik]

Another question: how can I read file line-by-line?

(Sry previous was wrong 😅)

Just use str = app.ReadFile("filepath");
You can get an array of the lines that way:
lines = str.split('\n');

Hope this helps

I would normally use the method suggested above.

However if the file is very large or you have some other good reason to read it line by line, you can open the file for random access.

var fil = "/sdcard/sh_out.txt";
//Called when application is started.
function OnStart()
{
//Create a layout with objects vertically centered.
lay = app.CreateLayout( "linear", "VCenter,FillXY" );
//Create a text label and add it to layout.
txt = app.CreateText( "",0.9,0.5,"log" );
lay.AddChild( txt );

//Create a button
btn = app.CreateButton( "Read" );
btn.SetOnTouch( readLine );
lay.AddChild( btn );

//Add layout to app.
app.AddLayout( lay );

//Open file for reading
file1 = app.CreateFile( fil,"r" );
readLine();
}

function readLine()
{
var s = file1.ReadText("Line");
txt.Log( s );
}
