The Andriod kernel is based on the Linux kernel, but it is not the same. It is a modified version of it (written in C). You are correct it contains an application framework which includes Java-compatible libraries based on Apache Harmony. Android uses the Dalvik virtual machine with just-in-time compilation to run Dalvik 'dex-code' (Dalvik Executable), which is usually translated from Java bytecode. That is how it is able to run application software written in Java.

Android kernel is Linux kernel, plus couple incompatible frameworks (say duplicating v4l functionality etc)
Yes, dalvik seed forks other dalvik processes for applications, but there are other (Linux) processes like 'rild ' etc that are written in C and has no relation with dalvik.
The term 'tasks' is not proper in context. All dalvik applications are processes for linux. They become background tasks in Android task managers when thay are not visible (and still remain Linux processes....)
