Why are these permissions being refused?

Question

Just for the Heck of it, I requested all the permissions from my application (hello world), to see what are the types of permissions that are granted and what are those that are refused! To my amusement I found about 40 of the permissions not granted! Two were returned as unknown permissions.

Here is the log of all the permissions that were denied to me -

Now for a fact I know level two permissions are not granted to third party application developers and are reserved only for OEMs. But I am surprised as a lot of level three permissions have been denied to me (if not all!). Hence my question would be why is it so, do I need to add something else to my manifest for those permissions to be accepted? Also is not the system supposed to grant my permissions on the emulator because after all its for development? And is it intelligent as in it would reject permissions that it deems unreasonable of my application? Is android system that advanced that it understands code?

I would much appreciate it if you could actually explain me this concept in a couple of lines instead of pointing me to the regular permissions and security documentations. I have read through it a couple of times and I guess my understanding is lacking in some perspective. Hence I would much prefer to read some other attempt at explaining it to me. Thanks

Someone tested that before you, but that's an interesting thinking : http://groups.google.com/group/android-developers/browse_thread/thread/3af09c76f3ba8d96/d314c4adaaa217c4?show_docid=d314c4adaaa217c4&pli=1

Answer 2

Android permissions are separated to four groups:
- Regular
- Dangerous
- System or Signed
- Signed

Permissions in the first two groups can be granted to any application.
The last two can be obtained only by applications which are system - preinstalled in the device's firmware or which are signed with the "platform key", i.e. the same key that was used to sign the firmware.
