"Over the last few days I've gotten a number of inquiries about
smartphones and vertical market mobile apps, particularly as it
relates to compatibility with Android, BlackBerry and iPhone. One
reader, a Fixed Income securities trader, asked me about whether or
not his new DROID could run the BlackBerry software for CQG, a
popular live market data application.
"I explained to him that while Android and BlackBerry use
similar programming languages — the BlackBerry uses a
specific implementation of Java Micro Edition and Android uses
Dalvik, a source-compatible but bytecode-incompatible clone of
Java, the software applications they run are incompatible with each
other and that some degree of porting work would need to be done to
make CQG's J2ME application run natively on Android.
"This is further complicated by the fact that there are other
major smartphone platforms, namely the iPhone, Symbian and Windows
Mobile which all use completely different APIs for native
application design, which make the BlackBerry to Android porting
look trivial by comparison. So what is a vertical market mobile
application developer to do?"
