Run script with android app

Question

i've got this shell script:

#!system/bin/sh
while :
do
sync
echo 3> /proc/sys/vm/drop_caches
echo "Script is been launched"
sleep 30m
done
exit 0;

i wish run this script with an android app. I have already created a button with only a toast for now. How can i take the script (free.sh) and launch it with the button on the app? Or is there a solution to rewrite the code in java? Thanks

First, you will use Eclipse to create a simple Android helloworld app. And add a button in your layout. This is very priliminary practise of Android development which you can dig a lot more from http://d.android.com

please try this code in your button's onclick call back function:

Button b = (Button)findViewById(R.id.buttonPower);
        b.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
                Process p=null;
                try {
                    p = new ProcessBuilder()
                    .command("PathToYourScript")
                    .start();
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    if(p!=null) p.destroy();
                }
            }
        });
