Java Development

[FrugalHorn]

Greetings!!

I am using a JDE4.5.0 and Pearl 8310 for testing. I have used event injection in my application.

I install the app on the device and click to edit configuration, device throws an error Symbol ‘EventInjector $KeyCodeEvent.<init>’ not found.

I have ensured,

1. The code is signed.

2. App is given appropriate permissions before invoking it.

3. The .csl file has an entry "52525400=RIM Runtime API".

Everything works fine in the simulator but no good on device. Please can someone pass a clue as to what must have been wrong?

Thanks,

Seems that JDE version is newer than your actual device OS software version number.

Check JDE version via menu: Help - About

On device go to Options - About

Now compare device OS version and JDE (RIM API) version.

device OS version has to be equal or bigger than JDE version you used to compile the application.

The error occured because there is an unresolved reference to a class/method in actual device OS.

Your application contains a reference to a class/method, but this reference cannot be resolved by actual device OS.

The reason I described in previous post.

Thank rafo.

I had learnt what you are suggesting from this page:

In my case the,

4.5.0.7   is the JDE version and

4.5.0.44 is the Device version.

So thanks but the issue seems to be somewhere else.

The problem is as I described.

You have to have at least 4.5.0.7 or bigger version of your device software to run code compiled on JDE 4.5.0.7

4.5.0.44 is older than 4.5.0.7

and therefore you get error message.

You need either to use JDE 4.5.0.44 or older or update your device software to 4.5.0.7 or newer.

I'm failing to understand something here.

How can 4.5.0.44 be older than 4.5.0.7? Does RIM name the versions number backwards? With that analogy is 4.5.0 older than 4.4.0?

4.5.0.7 semantically is the same as 4.5.0.70

Just add zero to align the number.

4.5.0.7 (4.5.0.70) is newer than 4.5.0.44

I agree that RIM provides very strange approach in version numbering without number alignment.

From logical point of view 0.44 is less than 0.7

and therefore 0.7 is bigger (newer) than 0.44 version.
