Below is the onCreate method

cheers

Below is the onCreate Method

/**
 * provide an interactive shell in the screen
 */
@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);
    shell = (EditText) findViewById(R.id.shell);
    //      shell=new ShellEditer(this, null, null);
    setContentView(shell);
    shell.setEnabled(false);
    initializeShell(shell);
    Handler hd = new Handler() {
        public void handleMessage(Message msg) {
            if (msg.getData().containsKey("initial")) {
                alert("initialized");
                shell.setEnabled(true);
            } else {
                shell.append("\n"+(String) msg.getData().get("result"));
            }
        }
    };
    //running the backend
    new Thread(new Runnable() {
        public void run() {
            try {
                Runtime.getRuntime().exec(
                        "dalvikvm -classpath "
                                + "/data/app/Jythonroid.apk "
                                + "org.python.util.JythonServer");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }, "JythonServer").start();
    shellclient = new ShellClient(this, hd);
    new Thread(shellclient).start();
}

I am now getting the following error trying to run this app from the shell any idea how I can achieve what I am after

$ dalvikvm -classpath org.python.util.apk org.python.util.jython
dalvikvm -classpath org.python.util.apk org.python.util.jython

$

it seems it can't find the Path and honestly I am not sure where it is. In the FixMe.java file of my project I set it to

public static String apkpath = "/data/app";
public static String apkname = "org.python.util.apk";
public static String apppath = apkpath + apkname;
public static String tmpdirpath = "/data/jythonroid/";

But I am unsure that I can write to those paths what should I set those to *cheers

last update I solved most my problems and now get a shell just I get a few errors when running it any ideas how to fix these cheers

Answer 1

One problem looks like you are adding a child view to another view - but that child view has already been added. Are you dynamically adding a view or building a layout? E/AndroidRuntime( 190): at org.python.util.Jythonroid.onCreate(Jythonroi d.java:251)

Answer 2

This call seems to be out of place

setContentView(shell);

I'm assuming that R.id.shell is in your main XML, because otherwise you couldn't do this:

setContentView(R.layout.main);
shell = (EditText) findViewById(R.id.shell);

If that is correct, there is no reason for the setContentView, as it is allready in the main you've just set.
