customized share button

[pravin...@gmail.com]

i was trying to implement a share button with two services sms and email..here is the code
 protected void onMain_Button1Action(Component c, ActionEvent event) {
        super.onMain_Button1Action(c, event);
        Form f = Display.getInstance().getCurrent();

        t = findTextField(f).getText();
        Vector v = new Vector();
        SMSShare s = new SMSShare();
     // EmailShare e = new EmailShare();
        v.addElement(s);
     // v.addElement(e);
        for (int i = 0; i < v.size(); i++) {
            ShareService share = (ShareService) v.elementAt(i);
            share.setMessage(t);
        }
        List l = new List(v);
        l.setCommandList(true);
        final Dialog dialog = new Dialog("Share");
        dialog.setLayout(new BorderLayout());
        dialog.addComponent(BorderLayout.CENTER, l);
        l.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent evt) {
                dialog.dispose();
            }
        });

        dialog.show();
    }

when i click on  post button it shows  java .lang.NullPointerException and den it sends sms .....( I dont want to use all native services i want to use only sms service so i did modify code accordingly )

it works properly on emulator....shows NullPointerException on an android and j2me cellphones

[Chen Fishbein]

Hi, this throws nullpointer on emulator as well, I am guessing you're project is not up to date.

The problem is that the ShareService needs the go back to the original Form once the share succeeded use setOriginalForm(Form original)

[pravin...@gmail.com]

hii Chen... u r correct  my project was not up to date....it shows null pointer exception on emulator too.....with ur suggestion i have  added setOriginalForm(Display.getinstance().getCurrent()) method, and that worked on emulator properly but on android cell phone contacts are not getting loaded and app crashes while my application loads contact....

//code

protected void onMain_Button1Action(Component c, ActionEvent event) {
        super.onMain_Button1Action(c, event);
        Form f = Display.getInstance().getCurrent();
        t = findTextField(f).getText();

        final Vector v = new Vector();

        SMSShare s = new SMSShare();

        EmailShare e = new EmailShare();
        v.addElement(s);

        v.addElement(e);

        List l = new List(v);
        l.setCommandList(true);
        for (int i = 0; i < v.size(); i++) {
            ShareService share = (ShareService) v.elementAt(i);
            share.setMessage(t);

            share.setOriginalForm(Display.getInstance().getCurrent());

        }


        final Dialog dialog = new Dialog("Share");

        dialog.setLayout(new BorderLayout());
        dialog.addComponent(BorderLayout.CENTER, l);

        l.addActionListener(
                new ActionListener() {

                    public void actionPerformed(ActionEvent evt) {
                        dialog.dispose();
                    }
                });
        dialog.show();

    }

I have added following permission for reading contacts  :
key===>android.xpermissions
value===><uses-permission android:name = "android.permission.READ_CONTACTS" android:required="false" />
now contacts are loading properly but cant send sms....when i clicked post button it shows User 100079 does not have android.permission.SEND_SMS

[Chen Fishbein]

add the sms permissions as well until we will fix the permissions in the build server.
