Is there an API in android to access the headphone hardware input? Ideally I'd like to be able to directly read the incoming voltage/current. Accessing this in either Java or the NDK would be fine. Preferably if there's a way to do this on non rooted phones. ...
Hi, I compiled the hello-exe sample, which is contained in the Android ndk. The problem is that I don't know how to run it on the emulator (I'm using the Windows emulator). Any ideas?

I have Java class which initialized with data from file. The init process is slow. Is is possible to move this initialization to NDK level? Is it possible to create my user defined class in NDK and return it into SDK? ...
Hello, I was wondering if there is an easy way to get the current time in native Android code. Optimally it would be something comparable to System.getTimeMillies(). I will only be using it to see how long certain function calls will take so a long variable with the current time in milliseconds would be the optimal solution for me. Tha...
So I'm writing an Android app which uses a large c++ library. I have everything working so that the java app can call the c++ delegation methods, but I'm finding myself wishing I could log messages from c++ to the Android log. This is easy from java, but I'm at a loss as to how to call a java method from c++. My searches found methods...
Hey all, this is briefly what im trying to do: Im making an Android application that uses C++ libraries compiled from the Android NDK. Some of these C++ libraries create connections and act as servers to report data over a wifi connect (i am not trying to use the phones 3g connection or anything similar). The connection will be created u...
I'm looking for a way to decode AAC natively to PCM on Android. The decoder source code is at http://android.git.kernel.org/?p=platform/external/opencore.git;a=tree;f=codecs_v2/audio/aac/dec;hb=HEAD, but I'm not familiar with NDK at all. 1) There's no way of doing this directly using the Android SDK, but can this be done via the NDK? ...
I've got some C functions which I am calling through JNI which take a pointer to a structure, and some other functions which will allocate/free a pointer to the same type of structure so that it is a bit easier to deal with my wrapper. Surprisingly, the JNI documentation says very little about how to deal with C structures. My C header...
Using AIR for Android, is it possible to call from Flex into an NDK library? If so, how can this be done? I have a large C library that I need to use. I know that I can do this from an Android Java app (through JNI), but I have a large Flex codebase that I'd like to reuse. ...
I have a large C/C++ library that I need to use as part of an Android NDK project. This library needs to be able to intelligently process UTF8 strings (for example, conversion to lowercase/uppercase). The library has conditional compilation to punt to an OS API to do the conversion, but there don't seem to be any Android APIs for UTF8....

(See http://stackoverflow.com/questions/456211/activity-restart-on-rotation-android). My question is, what is the correct way to handle this from a Native code perspective? e.g. if I have a sta...
