How do we do programmatic reading of a barcode that is captured using a mobile phone camera? For example, how do that using iPhone or Android or Java ME? Do we need separate hardware to read bar code or can we do image manipulation? Google has made this INCREDIBLY simple with their Zebra Crossing libraries. They have support for doing scanning via images on the following platforms: J2SE Android and others have ported to: J2ME CSharp CPP Rim iPhone Bug As another poster already mentioned, on Android you could also use an Intent to call Barcode Reader with something like: public Button

I have list items on form, I have to display that form on tabs, when the user clicked on a tab. How to add that form to tab, after form.show() or before? I need to display first tab as default with Form Screen? You can display form in Tabs. Form is also a component. Form frmObj = new Form("Tabs Example"); Form frmOne = new Form("One"); Form frmTwo = new Form("Two"); Tabs tabObj = new Tabs(); tabObj.addTab("Form One",frmOne); tabObj.addTab("Form Two",frmTwo ); frmObj.addComponent(tabObj); frmObj.show(); 来源： https://stackoverflow.com/questions/11862237/how-to-display-a-form-screen-on-lwuit-tabs

I am having an application build using j2me lwuit. I need to send e-mail from that app. To make your application smaller, I'd suggest to implement SMPT over a SocketConnection . For small e-mails this shall be pretty straightforward: SocketConnection connection = (SocketConnection)Connector.open("socket://your.smtp.server:25"); DataInputStream is = sc.openDataInputStream(); DataOutputStream os = sc.openDataOutputStream(); //now the SMTP chat with server Using this approach may allow you to make your application to be depend only on MIDP/CLDC profiles, thus to be easier portable to other phones
