Flash Lite adoption is growing at a very rapid rate. It is most probably because it is so easy to code for and there are so many Flash designers/developers out there today that have now found a new media outlet – mobile phone users. So watch out Symbian (C++) and Java Micro Edition (JavaME,J2ME) you have a new contender in the arena.

Use this code for the 2nd edition. Note that the first half of the if statement is just so that the code works on the emulator. This is because the emulator uses a Dynamic Link Library (DLL), therefore we need to employ library functions. However the overall outcome is the same.

This code only works on S60 3rd Edition.You can use it to invoke an executable from with your application. Make sure you cleanup after youself and don’t leave any rouge applications running in the background.

The time is now! Mobile technology is to sky rocket with the consumer base forever upgrading their mobile phones. Java-enabled phones together with Symbian OS phones make life and business much easier. Download the Midlet Development Kit and Symbian SDK and get started. Unleash your website to the wireless network. Deliver real time content to your clients via mobile.

If you have been reading discussions at Forum Nokia Developer Discussion Board recently, you may notice there are many questions about signing in S60 3rd Edition. It seems the new security feature in Symbian 9 has led to frustration for some developers.

I would like to share what kind of error messages I have seen when installing signed/unsigned application in S60 3rd Edition phones. There is a hint that explains what may cause a particular message. I may not be able to cover all error messages because I may not have seen all of them.

Hint: You may have tried installing unsigned application. Note that signing is mandatory S60 3rd Edition. You can use self-signed certificate or developer certificate from Symbian Signed to sign your application.

Message:Unable to install. Constrained by the certificate.

Hint: This message pops up when you attempt to install developer certificate in the unsupported device. The developer certificate from Symbian Signed can only be used in a limited number of devices. Remember that you have to send your IMEIs to Symbian Signed when requesting certificate. You cannot use the certificate in other devices that is not in your IMEIs list.

Message:Required application access not granted

Hint: Check that your certificate can be used to sign all capabilities needed by your application. For example, if you use self-signed certificate, you can only sign basic set capabilities, i.e. NetworkServices, ReadUserData, WriteUserData, LocalServices and UserEnvironment. If your application requires one of the extended capabilities, for example SwEvent, you cannot sign it with self-signed certificate. In this case, apply for developer certificates from Symbian Signed.

Message:Unable to install a protected application from an untrusted supplier

Hint: If you use self-signed certificate, make sure that your application uses unprotected UID, i.e. 0xA0000000 – 0xAFFFFFFF. If you use protected UID (0×20000000 – 0×2FFFFFFF) or legacy UID (0×10000000 – 0×1FFFFFFF), you will get this message.

Message:Unable to install

Hint: This message may come up when your installation file (.sis/.sisx) copies files to other application’s private folder, i.e. privateuid. Note that Symbian 9 introduces data caging concept, it means you don’t have access to other application’s private folder.

Like this:

This useful application will let you record incoming and outgoing phone calls! CallRecorder can start recording automatically or ask whether to record a conversation or not – this will depend on the rules you set.

With version 1.13,in the directory of FExplorer a console exe file : EXETEST.EXE (you can run it), the purpose is only to test if FExplorer can run EXE files on your phone.

* restoring the last path in views :

After leaving the ‘about box’, ‘settings’ or the ‘editor’ view, if FExplorer return to the root directory, check that the ‘save last path’ in the settings is ‘ON’, not only this settings is used when leaving FExplorer but i’s also used in all the differents ‘views’ (06/03/2005).

* how to switch between the text/hex viewer :

Simply, go to the settings and choose the viewer type : text or hex (06/05/2005).
