How to identify front and back camera's Megapixel of an android device by using Android code? I had tried CameraInfo but am not getting megapixel. For example, To identify Model of device we are using this android.os.Build.MODEL . Likewise any method to identify Megapixel of front and back camera. Advance thanks for any help. If the device is "Videocon A53" features are (540x960 pixel) display and runs Android 4.1 Jelly Bean, 8-megapixel rear camera , 2-megapixel front-facing camera . Now i want to get that 8 megapixel and 2 megapixel by android code I got megapixel by combining three

I need to access motheroard identification (serial, manufacture, etc) in my application on multiple processes. I have been able to successfully query this using WMI, but I'm looking for an alternative. If you care to know situation: I have some application behavior that is different depending on the hardware configuration, or if a particular environment variable is set (for testing purposes). bool IsVideoCardDisplay = ( getenv("Z_VI_DISPLAY") || !QueryWmiForSpecialBoard() ) ? false : true; When the environment variable is set the WMI query isn't necessary--the application runs fine. However,

Not sure that this is the right site for this question, but since there are many smart people here maybe someone knows. I'm building an app that needs to capture video continuously, but keep only the last few minutes (say 5~15). It is easy to implement this by splitting the video to 30-seconds files, and delete the least recent ones. However, this means that the app writes and erases large files all the time, and I'm worried that it'll wear the device's flash memory. I've been trying to find the P/E cycles spec for the iPhone (and for popular Android phones), with no success. Does anybody know

How would you detect if the user presses the volume hardware buttons and prevent default behaviour? Thanks a lot. Matt S. Look at AVSystemController_SystemVolumeDidChangeNotification (or alternatively here ) 来源： https://stackoverflow.com/questions/3722239/iphone-sdk-4-how-to-programmatically-detect-volume-hardware-button-press

I've been working on a physics simulations requiring the generation of a large amount of random numbers (at least 10^13 if you want an idea). I've been using the C++11 implementation of the Mersenne twister. I've also read that GPU implementation of this same algorithm are now a part of Cuda libraries and that GPU can be extremely efficient at this task; but I couldn't find explicit numbers or a benchmark comparison. For example compared to an 8 cores i7, are Nvidia cards of the last generations more performant in generating random numbers? If yes, how much and in which price range? I'm

I need help figuring out how to check if a device is equipped with the search hardware button or not. Is this possible? EDIT: I'm talking about finding out if the device has the search hardware button or not. Simple question. Each android device has a set of hardware buttons; menu, home button, back button, and search button. But some devices is only equipped with some of them, not all. EDIT 2: The reason why I ask is because I want to have a software button showing in my UI if the device is not equipped with a hardware button. I am using the searchable interface in my activity. I am not
