It is ultimately not possible to do so with certainty. You can obviously check for common characteristics such as android properties, extra setuid executables or processes running as root, but latent capability may not be visible in that way, and you are implicitly assuming that the operating system is truthfully reporting the facts you check, which is not necessarily the case. -- You received this message because you are subscribed to the Google Groups Android Developers group.

serializer.attribute(null, name, name);

a reorganization)

For reasons of both economy and security, the majority of mobile network providers do basically the same thing within their network infrastructure - your mobile device simply does not have a unique, routable external IP address on which it can accept incoming connections or unsolicited incoming traffic. Could you please post some other suggestions for setting up a P2P connections?? You will probably end up having to have an intermediate server on the publicly visible Internet which both mobile devices can connect to. It may be possible, with a lot of effort to set things up so that the server can give each device enough dynamic information about the other that they can subsequently trade packets directly for the remainder of that session, but server help in setting things up will be needed. And in many cases with mobiles, I suspect the ultimate data flow remains mobile-server-mobile rather than directly mobile-mobile. -- You received this message because you are subscribed to the Google Groups Android Developers group.

This is actually not strictly an NDK issue, rather then NDK is making a universal aspect of Android apps a bit more easy to see. On an ordinary system, programmers think in terms of a process. These exist on android too, but there is not a 1-1 correspondence with activities. Even when all activities and services hosted by a process entirely finish, android will try to keep the process around for a faster restart of that app, killing it off only if the system becomes memory constrained. In the ordinary case, when a user re-enters a recent activity, it runs in the old process that is still around from the last time. But that is of course not always the case - sometimes the old process has been reaped (or it has crashed, or was never previously run) and a new one must be created. The NDK is not unique in having certain things that can survive with the process, irrespective of the component activities or services - that can happen with the java code too. However, appropriate practices for handling this for ndk code might indeed be better on the ndk group. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Most embedded chips, especially those intended for battery powered systems, have various peripherals such as timers external to the cpu core which can continue to operate even when the cpu core is powered down. In the chips used in most contemporary smartphones, one of those peripherals is actually an entire additional arm processor core, charged with running the radio and other things such as low level audio and button I/O. The power state of that processor is quite independent of the power state of the application arm processor which runs the Linux kernal, android stack, and SDK apps, so checking in with the mobile network infrastructure does not involve waking up the application processor.

[android-developers] Re: Database access from another android phone.
Since devices on mobile networks generally can't be reached by incoming connections, you will probably have to have a server somewhere which all the mobile clients check in with so it can forward traffic between them (possible using C2DM to get their attention). You will have to build functionality into the app running on each device so that it can accept requests for db operations from the server.

To reproduce any digital signal, you MUST sample at twice the frequency of the highest frequency you want to reproduce. In this case, you'd have to sample at a minimum of 34,000 samples/second. HOWEVER. Not exactly true. What is true is that frequency components above the threshold appear like, and cannot be distinguished from, frequencies below it. To avoid this confusion, it is common to remove them with a low pass filter before sampling. However, this is not the only way of doing things. It is also quite common to use a filter with selects frequencies above the threshold, and take advantage of the sampling folding them down to a frequency range where they are easier to deal with computationally. Obviously that's more common in communications equipment where you are only interested in a narrow range of frequencies, rather than baseband voice or music. When I analyze the recorded sound, 17kHz frequencies aren't there, its like the phone has a low pass filter that eliminates these frequencies. Yes, the *PHONE* certainly does...but where? The question is, does the non-phone portion of the Android device have access to the raw audio, or has the low-pass filter already been applied? Check to see if you can record frequencies above 5 kHz (DS0[1] is 300--3400 Hz, but since there are no brick-wall filters, it usually extends to about 4000 Hz, and then we allow a bit extra to make sure). If you can access up to 5000 Hz or higher, you're getting audio before the low-pass filter. Before *which* low pass filter? A device intended to be used for both telephony and higher quality audio likely has several. There is probably something in front of the actual ADC (likely on chip) which prevents aliasing in the sampling itself. There may be an intermediate filter in the audio system if any resampling is done, and this may depend on the sample rate requested by the program. And then there's probably one in the GSM or SIP or whatever encoding system to limit to the narrower voice bandwidth of those channels. -- You received this message because you are subscribed to the Google Groups Android Developers group.

This command does not (and fundamentally could not) change the userid of the process requesting its execution. It can only result in a new process running as a different userid. If you want to do something as root, you have to get the process (typically a shell) created by su to do the thing you want to do. Typically people do that either by specifying the command as an argument to su (which in many cases is not supported) or more portably by piping further commands into the stdin of the su process.

The adb port forwards you were trying to use earlier do work on real devices, but you have to make the phone the server and the pc the client, ie, the PC can initiate a connection to the phone, but the phone cannot initiate a connection to the pc. When using port forwards you do indeed use the loopback address, since you are actually contact a local port, which gets forwarded to a remote one by adb. And you said that I should setup a network between the PC and the android phone, I tried the Internet Tethering. And now, it works! I don't get what is reverse tethering yet, but I will go in deeper steps. Various tether capabilities may enable this, or have the side effect of putting the phone and computer on a network segment.

On Tuesday, February 28, 2012 1:40:18 AM UTC-5, David Henning wrote: I'm looking for some help understanding the current USB Host capabilities of the latest Android smartphones versus an embedded processor running a standard Linux build. I've done quite a bit of driver-level Linux development, but I'm totally new to Android. If you are in a position to install a customized kernel and alter the system partition of the devices, you can use ordinary embedded linux methods. Your main hiccup is figuring out how to give an android application user id - which is usually allocated by the package manager - access to the device files, though if you are okay with giving all user id's access that's a non issue. What android itself typically does for hardware is give ownership of them to semi-privileged GIDs which some system apps are able to acquire via matching android permissions. Many of even first generation android devices are able to be USB hosts in this manner (see thread on the android kernel group, and on xda developers), though most of them would require custom wiring as they are unable to power usb peripherals. I believe Honeycomb and later introduce some android-style APIs for talking to USB peripherals from userspace without per-device kernel drivers - something akin to libusb, though obviously not libusb. It's not something I've yet had cause to try it personally, but the docs are at h ttp://developer.android.com/guide/topics/usb/host.htmlhttp://developer.android.com/guide/topics/usb/host.html . As a general comment, working on a USB host project (using either linux or android methods) on and android device will be an exercise in extreme frustration unless you have a uid-shell (or better) shell session running on it via some non-usb channel that remains available while testing your USB host project. That likely means either getting ADB's daemon listening on TCP (if you have root) or else launching an ssh server from the adb shell before unplugging from the pc and switching to host mode. -- You received this message because you are subscribed to the Google Groups Android Developers group.
