Any pointer to how one can develop C++ apps for Droid?
Actually, as dongdong pointed out, you can use the Native Development Kit (NDK) to get C/C++ code running on the device. This works by writing native libraries that are packaged with your Java code.
However, the compiled libraries are processor-model specific, so your application will run on some devices and perhaps not others.
Also, you cannot write entire applications in C/C++. There are only a limited set of libraries available to the C/C++ code.
This ability is made available mostly to support high-speed, low-level coding for special needs. It's not really a great general-purpose option yet, but may be some day.

Mosync SDK Look it up. It's cross platform. Hope that helps. I've been using it for a few weeks now.
EDIT: I realise the OP question is old but I figured I'd throw it out there anyways because the thread was resurrected.
