Then recognize H264 frames in the internal buffer and send frames to caller java class. Launch Android Studio: And under Configure select SDK Manager: From here install LLDB (the native debugger), CMake (the build system we’ll use. You must define an internal buffer in your code and put received stream to the end. I will give you this special char arrayĢ- A loop with 25 millisecond iteration that reads stream from simulator and calls 'onStream' method in caller java class and send byte as result. So I need a native class with these methods :Ĭonnect to the simulator and send special char array as start instruction. I have a simulator that is ready to accept TCP Connections from port X and then sends stream data to the client buffer with H264 data format. I need a NDK small project that has one class with 3 methods. so code can be developed in a separated small Android NDK Project.

Pro Android C++ with the NDK also covers the following: Using a game app case study, this book explores tools for troubleshooting, debugging, analyzing memory issues, unit testing, unit test code coverage, performance measurement, on native applications, as well as integrating the Android NDK toolchain into existing Autoconf, Makefile, CMake, or JAM based build systems. Pro Android C++ with the NDK is an advanced tutorial and professional reference for today’s more sophisticated app developers now porting, developing or employing C++ and other native code to integrate into the Android platform to run sophisticated native apps and better performing apps in general. The native-code support on Android offers endless opportunities to application developers, not limited the functionality that is provided by Android framework.
