Advertising API for Java ME applications? - java-me

I know AdMob is not for Java ME.
Do you know any other advertising API or services that can be used in Java ME application?
It might be really good if I can earn some money with my free Java ME applications.

http://adfonic.com/ Adfonic is what can I find now.
You can follow it's instruction from http://developer.adfonic.com/index.php/Getting_Started to allow mobile advertising from Java ME application.

VoIP android studio

Hi I'm not very good with coding but I'm trying to learn as much as I can. I've been looking for tutorials on how to create an internet call app on android studio. So far I haven't found any. If anyone knows a process that could guide me I would very much appreciate it.
You can use android's own implementation
Session Initiation Protocol
from docs
Android provides an API that supports the Session Initiation Protocol
(SIP). This lets you add SIP-based internet telephony features to your
applications. Android includes a full SIP protocol stack and
integrated call management services that let applications easily set
up outgoing and incoming voice calls, without having to manage
sessions, transport-level communication, or audio record or playback
directly.
or other third-party libraries like following.

How do I change a Java ME device System time?

I'm developing an application that needs to synchronize the time on a server with the time on the device.
Blackberry devices have the net.rim.device.api.system.Device.setDateTime(long dateTimeMillis) method for this. I'm looking for something similar in Java ME devices.
I can live with manufacturer specific APIs - specialy nokia, sony ericsson and motorola ones, and most JSRs.
Does anyone know if there is any way to do this?
Most manufacturers, such as Nokia, don't have that functionality in Java. You may need to take a look into Symbian C++ and other platform specific development tools.
You can't do with Java-me for some security reasons. So you can't change the internal time of system. You can possible to get the current time only.

How to communicate with mobile devices using Bluetooth in j2me?

I need to develop a project based on Bluetooth in mobile. Since I am new to j2me I studied some of the articles and run the project until the discovery of devices and services. I need to communicate between devices and transfer the desired files. I search code for client server communication through Bluetooth and got it but I didn't know how to run those code and implement further.
I have go through articles and I can run client server communication. Now I need to transfer the file and communicate to the user which was beyond the limit of my mobile through the another mobile which was within my limit.
JSR82.com has many articles and tutorials about how to use bluetooth from J2ME.
Better you refer the book, "BLUETOTH APPLICATION PROGRAMMING WITH JAVA API" by C.Balakumar. It is helpfull to you.

Paypal Related application in j2me and symbian

I want to know that can we make paypel related application in j2me and symbian OS?
Is it secure?
If we can make such application then can i get the api used for that.
Please help me for that.
Thank you
If you are asking whether PayPal offers any SDK for using the service on said platform through library APIs, the answer is no. See https://www.x.com/community/ppx/sdks?bn_r=m
If you are asking whether you could implement the NVP/SOAP APIs on this platform is: you could and it could be secure. It all depends on you ;)

Which mobile operating systems support J2ME?

I've been tasked with using WURFUL to determine whether or not a mobile browser is capable of downloading a J2ME app developed by my company.
I first thought I could use the "device_os" tag and filter by that, however, I'm unsure what the complete list of J2ME OS's are... any ideas?
I've been told there are no MIDP requirements, and that the application will run on any J2ME-supported handset (with two specific resolutions, which I already know how to query)
Thanks in advance.
There is no way to know all the OSes that support J2ME. Mainly because most feature handset comes with a proprietary OS which probably you have never seen before. It is a better idea try to identify the handset model and decide if it supports J2ME or not.
Another thing is, you may want to know which JSRs are supported by a specific handset. I do not know your application but probably you are using some optional JSRs that are not supported by some handsets although they have basic J2ME support.
Java ME SDK 3.0 includes a database of supported devices. Also there are other web sites that provides these kind of information. One example to those would be this J2ME Handsets web site.
If you are fine with just covering a large range of phones, you should include Symbian S60, S40, Windows Mobile, Blackberry and Android.
Symbian
Win Mob
Android
Almost every Sonyericsson phones
IMHO you don't have to worry about how many handsets support j2me because majority of the phones support it.
At least Symbian and Android.
