thanks for Lukas Morawietz’s answer in my this question https://plus.google.com/105062416156990739160/posts/3hqSu7pfMXJ

I add this part ‘ // write the current file’

it functions this:

– when press home button with preivous script, the target desktop maybe not the desktop I wanna

– modifiy current (variable in files) can make the home desktop be same with the current desktop.

The reason for this question:

– I definite the var for setHomeDesktop mannully

– I run this script outside of the LL 

Tips:

 If set the desktop mannually, we need root to view the config files to get the desktop ids in our mind.

//import java classes

LL.bindClass(“java.io.FileReader”);

LL.bindClass(“java.io.BufferedReader”);

LL.bindClass(“java.io.FileWriter”);

LL.bindClass(“java.io.File”);

LL.bindClass(“java.lang.System”);

//set Desktop with Id as Homescreen

setHomeDesktop=function(id)

{

//create the needed structure

var file=new File(“data/data/net.pierrox.lightning_launcher_extreme/files/config”);//this file contains desktop properties

var r=new BufferedReader(new FileReader(file));

var s=””;

//read the file

var l=r.readLine();

while(l!=null)

{

s+=l;

l=r.readLine();

}

//change the property

var data=JSON.parse(s);

data.homeScreen=id;

//write the changed stuff back to the file

var w=new FileWriter(file);

w.write(JSON.stringify(data));

w.flush();

w.close();

// write the current file

var file_cur=new File(“data/data/net.pierrox.lightning_launcher_extreme/files/current”);//this file contains desktop properties

var r_cur=new BufferedReader(new FileReader(file));

var w_cur=new FileWriter(file_cur);

w_cur.write(id);

w_cur.flush();

w_cur.close();

//restart the launcher

System.runFinalization();

System.exit(0);

}

setHomeDesktop(LL.getEvent().getData());
