I want to call a number in below format using platformRequest: platformRequest("tel:*123*33584744#"); But it gives me error Invalid number on the phone. But if i call this number manually by typing on phone then it works fine. Even below works fine: platformRequest("tel:33584744"); So i suspect problem lies when i put * or # chars in the number. As i said when i type these chars in the number manually and press the call button on the mobile it works fine but not with platformrequest. What is wrong I am doing? Any alternative to platformrequest method? How to call a number in below format: *123

In my J2ME app, I want show an alert dialog box only when the user changes the state of any controls—that is, when the user uses any of the control of the form and then try to cancel the form without saving typed data. For example among all 5-6 controls of form if the user types in 1-2 textfields and tries to cancel the form without saving that typed data into database. An alert box should then display with the message "Save changes?" with Yes, No command. How to do this? This is my code which does not give the desired result: import javax.microedition.lcdui.*; import javax.microedition.midlet

is there any possiblity in J2ME to convert an image (loaded from a png file with alpha) to a new transparent grayscale image? Until now I only got the rgb values, but not the alpha. Thanks. Edit: yes, it should be 32 bit grayscale. I found the solution and here is the code: public Image getGrayScaleImage() { int[] rgbData = new int[getWidth() * getHeight()]; image.getRGB(rgbData, 0, getWidth(), 0, 0, getWidth(), getHeight()); for (int x = 0; x < getWidth() * getHeight(); x++) { rgbData[x] = getGrayScale(rgbData[x]); } Image grayImage = Image.createRGBImage(rgbData, getWidth(), getHeight(),

Is it possible to dynamically make TextField element disabled and enabled during the run time in Java ME? according to API documentation, setConstraints(TextField.UNEDITABLE) could do something like that: Sets the input constraints of the TextField... Note if you need to preserve contents and modifier flags, parameter passed to above method might require some tweaking, like setConstraints((getConstraints() & TextField.CONSTRAINT_MASK) | TextField.UNEDITABLE) // "disable" - set UNEDITABLE above to disable, and to enable back, something like: setConstraints((getConstraints() & TextField

I am new to JSON programming in J2ME. I discovered that Json is used to exchange data much like XML. I want to know about the exchange in Array object from JSONtoObject and vice versa Below written is code where I convert from JSON to Object and vice versa. But I don't know about how to do for complex data structure like arrays etc. // App Loader import javax.microedition.midlet.MIDlet; import javax.microedition.midlet.MIDletStateChangeException; public class AppLoader extends MIDlet { public AppLoader() { // TODO Auto-generated constructor stub // Converting Object to JSON UserData data=new
