Does laz4android with android support indy component?
Although Indy supports FreePascal/Lazarus in general, it only supports Delphi's flavor of Android (and iOS) at this time. I don't know what changes would have to be made to support Android on FreePascal/Lazarus. At a minimum, it would probably require a new TIdStack-derived class to access Android socket APIs, and then you could set the global IdStack.GStackClass variable at app startup.
