Android vs Linux

Lazarus and Free Pascal already supports Android, some applications are already on the market. I already use it myself, both native Android and LCL Custom Drawn way.

I've tried some Android coding, using Lazarus, few months ago, but many questions left unanswerd to me. For example - can I use ordinary Lazarus classes for TCP (lNet class) or RS232 (5dpo). What, about bluetooth class for Android or using some new classes - like USB Host API or FTDI adapter class. Can I show new form, the way I do in Windows/Linux instead of using Android Intents.... At that moment, it seemed to me that I must often write JNI leyer, myself, which I consider (if I am not mistaken) not to be promissing.
I think, average programmer expect to use Lazarus the way similar to programming Windows or Linux (and their embedded variants), but seems to me it is not the case with Android (although I now that Android is quite different). Of course, something may be changed since my last Lazarus/Android attempt, or it is my missunderstandings.
And please if you can point me at some links, you consider to be much informative.

I can't answer this as I haven't used them.

Using LCL Custom Drawn, it's no different from desktop programming with Lazarus:
http://wiki.freepascal.org/Custom_Drawn_Interface/Android
You can check $(LazarusDir)/examples/androidlcl as it shows the power of custom drawn interface, single source for both Android and desktop, except for the lpr. In my project, however, I decided to combine the lpr with ifdef, as the difference is so minimal.

Thank you, I will investigate the matter, although communications are of primary interest to me. I did some in Java (WiFi and USB host), but it would be interesting of doing it in Lazarus.

By the way, there's LazDeviceAPIs for some hardware access.
