I haven't tried it yet but I guess if it's possible then http://developer.android.com/guide/topics/ui/themes.html should be the answer. Otherwise you could have a look at the AOSP sources to get the ultimate answer.

Oh. I suppose that if i get a /dev/something that acts like /dev/rfcomm we can use like a gps.

Ok then.

Thank

@Luis: Unfortunately there is no official way in Android to interact with an USB slave device. So it's currently not possible to do that. (Okay there might be some ways to hack it on certain devices.) In the future Android might add official support for that but currently I can't help you with that.

Hi, i have a question about the possibility of use a usb gps, not only a bluetooth. Can you give me some way to contact you (mail, skype, etc.)?

I'm ussing my google account so you can contact me this way.

Thanks

That's a pitty. I wanted to buy "Bluetooth GPS Provider", but it is not available on my market (Lithuania), Google states, that priced applications are not still available for this country :(

There is no demo version of Bluetooth GPS Provider. I realized that this isn't necessary since you can uninstall an app bought at the market within 24 hours and Google won't charge you for the app. I think 24h should be ok to test the app. So my advise is to buy the app and if it doesn't work with Navitel give it back (uninstall) within 24 hours. It would be also great if you could send me a mail if it works or not.

do you have a demo version of Bluetooth GPS Provider? I want to test it with Navitel or other gps software

J2MEUnit is just a unit testing framework like many others. In fact it's just a plain simple unit test runner without any bells and whistles.

JInjector is very different. It's capable of doing byte code magic to your classes. By doing that you can use it for e.g. test coverage analysis or doing system tests.

It can create wrappers for all the LCDUI classes and this way you can test you application at the UI level. e.g. you can have tests that fill in some data into a form and simulate choosing an command. Then you can verify that your code did what it's supposed to do by checking if the next screen displays the right stuff.

I once tried it and had a very hard time setting JInjector up and to be honest I don't think it's worth the hassle. These kind of tests break too easily and are very hard to maintain.

Unless the tool you use for these tests isn't really easy to use it might be more effective to do manual acceptance / system testing.

But nevertheless you should certainly do automated unit testing.

By using the approach outlined above you can do test driven development for J2ME which wouldn't be reasonable to do with on device unit testing because the turn around times are way too long.

I also think that doing code reviews is better than nothing. But I think that in a lot of cases they are done wrong or at least they could be improved.

In my current job we are doing formal "after the fact" reviews. When the code is already committed to the SVN someone has to review it. This might happen sooner or later. Maybe much later depending on the current workload.

In a former job we had no formal reviews but depending on how important the stuff was we did "pair reviews" before committing to the SVN or merging into the trunk.

I think that pair reviews are the way to go if pair programming is not an option.

Sitting in front of one PC and reviewing the code together with the original author really makes a lot of sense. Especially if you have a huge chunk of code to review.

Agreed: anything that can be automated with tools like PMD, etc. should be automated. It's a waste of time to have developers point out those issues.

Your comment about "it's unlikely that you have enough understanding of other parts of the code to do really useful code reviews" is the crux of the issue.

Even if, however, I don't understand the code well enough to ask "why did you do it this way?" I can still ask: "is this the functionality that the code is supposed to deliver?"

For example, one technique is to just review the unit tests (assuming that your team is using unit testing). By asking about boundary conditions and assumptions made by the code, you can help uncover gaps in the implementation. No automated tool can spot bugs that are caused by an incorrect interpretation of the requirements (e.g. "no, the code is supposed to divide that value by 10 in that situation, not by 20.").

Pair programming, as you point out, is a great way to get to collective code ownership (especially if you mix up the pairs on a regular basis). But if the team won't go for pair programming, code review can be an important step in the right direction.
