Laz4Android is just a prepackaged Lazarus + FPC + Android NDK. You can create Android apps using Custom Drawn Interface, but it's very incomplete and non-native.

Has anybody actually done this? I don't do that, though. Even if technically possible, there are hidden stuffs you have to be aware of. main() is only a specification in C standard, where the user code starts. However, long before that, there's a startup mechanism specific to each implementation. In GCC, this is _start, absolutely non-portable.

Re: [Lazarus] Packages and units with the same name

FPC units are organized in folders for easier management at filesystem level, but filesystem is not the namespace, there can never be /first/path/to/a.pas and /second/path/to/a.pas used in a single program, because only that a identifies the unit, not the path to it. This is the same as you can't have two files with the same name under the same path. Indeed you can't control unit names written by 3rd party and collision might happen, so most package developers add prefix in their unit names (e.g. IdGlobals) or use the new dotted unit names (e.g. my.globals.types, your.globals.consts). > So, the main program shouldn't know nothing about "private units" that > belongs only for the package.
