问题 Given that there are many sizes and color depths for different phones (even for the same manufacturer), i would like to have one application for all of them and then, download a proper icon for the phone de app is downloaded into. Is there a way to change the MIDLet icon once the application is downloaded? 回答1: As far as I know there is no way of doing this. You can however force the user to upgrade an app and change the icon then. This can be done in a more user friendly manner without loss

问题 I know this question was asked before. but i really don't know how to do this. I created a j2me app and a webservice in a tomcat server, it works perfect on HTTP, Now i need to connect to HTTPS/TLS.

问题 I been looking around and at sources like this one they say that a Midlet can invoke another if they are in the same suite, or if they are in the same namespace and in the same jar file. I do not understand what a Midlet-Suite is? Also after searching through the web I did not find any documentation or code examples for One Midlet invoking another Midlet. 回答1: The other replies are pretty much taking care of your questions about MIDlet Suites but I would suggest reading the MIDP specification

问题 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.

问题 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. 回答1: 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
