If you can't find the software you need for your phone, or just have a few ideas for developing a new one, you can write a mobile app yourself. You can also create games.
Necessary
Nokia SDK or J2SE and J2ME Wireless Toolkit
Instructions
Step 1
Download the software necessary for writing applications to your computer. You can use any programs that are convenient for you to use. You will need a compiler that creates mobile app archives, emulators for testing, a text editor, or any other program that is convenient for writing code.
Step 2
Your best bet is to use the J2SE compiler and the J2ME Wireless Toolkit. There are also special programs that combine this functionality in one installer, for example, Nokia SDK. To create a project, it is best to immediately choose a program that you will use in the future, since you get used to one. It will be difficult to rebuild to another in the absence of the necessary functionality in it.
Step 3
Create a new project in your editor, give it a name and other necessary attributes. Write a software code for a mobile device, alternately testing it with different phone emulators to find bugs.
Step 4
After you edit the program code, after checking it, pack it into jar and jad archives, and then save the file to your computer's hard drive. Copy the installation file to your phone, if necessary, also use it to check the functionality of the software you wrote for mobile devices.
Step 5
If you want the software you have written to be available for download on the Internet, post it on a specific portal. You can either provide it for free use or assign a certain amount for downloads, however, in the second case, you will have to choose a special resource that supports this function.
