Run script with android app

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();                }            }        });

Here is how you can run shell script from your android app

try {            Process process = Runtime.getRuntime().exec("sh /sdcard/test.sh");            BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));            String listOfFiles = "";            String line;            while ((line = in.readLine()) != null) {                listOfFiles += line;            }        }        catch (IOException e) {            e.printStackTrace();        }

Well, now No errors (THANK YOU!) but do nothing..to try i've written a easy script that write a file.txt. See the code:

package com.mkyong.android;import android.annotation.SuppressLint;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;  import java.io.IOException;import com.example.toast.R;public class MainActivity extends Activity {private Button button;public void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.tab1);    button = (Button) findViewById(R.id.button1);    button.setOnClickListener(new OnClickListener() {        @SuppressLint("SdCardPath")        @Override        public void onClick(View arg0) {            Process p=null;            try {                p = new ProcessBuilder()                .command("/sdcard/Script/scritturafile.sh")                .start();            } catch (IOException e) {                e.printStackTrace();            } finally {                if(p!=null) p.destroy();            }        }    });}}

The are no errors but when i press the button i think the shell doesn't go so don't create the file.txt
