All geek questions in one place

How close can we programmatically get to the hardware of an Android device?

the camera of my mobile phone (running Eclair-update1) remains immune in 90% of cases, so I first accepted a hardware defect. After breaking the cache and user phone data, they worked again. At least for a while. Now he did not work again.

While browsing the network, I found quite a few users who faced the same problem and had difficulty pulling out their user data from the device.

So my question is: how close can I get to the hardware using the SDK? I would like to write an application to affect the state of the equipment (for example, reinitializing the camera, reinstalling SDcard aso.), But I would prefer to do this - if possible - with the SDK instead of the NDK.

Thanks in advance!

This is not a sdk vs. question ndk, and basic permissions at the operating system level that prevent common (after-sales and anti-virus software) Android applications in general from making raw access to the hardware.
