java-me

I need my J2ME app to run in the background and still allow the user to use his mobile without problem. the app still needs to process some events in the background. I would also like to allow the user to stop the app if he wants to. How can I accomplish this? Running a midlet in the background but still processing is not specified in the j2me standard i think. Normaly at the moment your midlet is moved to background the paused method should be called. But not every vendor implements it that way. Symbian keeps your program running as if there was no change when minimized. At least on the N80

Is there any persistent storage for mobile application of J2me, like SQLite? If there is then please share the link or some example code of interacting a simple J2ME application with back end persistent database. Yes, there is persistent storage for J2ME - called RMS (part of MIDP 2.0) - look here for short tutorial. RMS doesn't related to SQL, it's just for persistency. if you're looking for SQL alike storage - read this discussion . Hope it would be helpfull. chiranjib Perst Lite is McObject’s version of the Perst open source, object-oriented embedded database for mobile and embedded

I intend to develop a J2ME application, that should be able to read words from the English Dictionary. How do I interface to/and store a Dictionary ? Will I have to create the Dictionary myself, by inserting words, or is there a third party Dictionary available with APIs? There are definitely free dictionary files, so you don't need to make one yourself! A good starting point is looking at a Java SE implementation of a spell checker, such as Jazzy on Sourceforge . It has dictionary files included in the project, and by inspecting the code you can get an idea of how to integrate it into your

I want to write app where user can point any place on map (not only cities) and get timezone in that place. What data structure (app will not have Internet connectivity) and algorithm should I use? Where I can obtain needed data (I wont more accuracy then divining map into 24 rectangles)? I will write my app in Java ME. Given that time zones are based on political entities rather than simply a physical lat/lon computation, I would create a data structure that mapped polygons over lat/lon coordinates into political entities (country and province/state) and then have a separate structure that

I have a java project that is referenced in j2me project and in android project. In this project i would like to use conditional compilation. Something like... //#if android ... //#endif //if j2me ... //#endif I have been reading about this but i did not find anything useful yet. sinek You could use Antenna (there is a plugin for Eclipse, and you can use it with the Ant build system). I'm using it in my projects in a way you've described and it works perfectly :) EDIT: here is the example related to @WhiteFang34 solution that is a way to go: In your core project: //base class Base.java public
