![]() Profiling native code using GProf to identify performance bottlenecks, and NEON/SIMD optimization from an advanced perspective, with tips and recommendations. Debugging and troubleshooting native applications using Logging, GNU Debugger (GDB), Eclipse Debugger, Valgrind, strace, and other tools. Native graphics and sound using JNI Graphics, OpenGL ES, and OpenSL ES. native multithreading, and the C++ Standard Template Library (STL) support. An introduction to Bionic API, native networking. An overview of Java Native Interface (JNI), and auto-generating JNI code through Simplified Wrapper and Interface Generator (SWIG). The Android platform, and getting up to speed with the Android NDK, and exploring the APIs that are provided in native space.Fortunately, the necessary CMake package config or ndk-build module will be automatically generated on your behalf. Pro Android C++ with the NDK also covers the following: Declaring the dependencies in your adle will cause Gradle to download those dependencies from Maven, but you must still instruct CMake or ndk-build how those dependencies should be used. 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. Android is a mobile platform that is built on the top of Linux operating system. Launch Android Studio, and it should detect presence of NDK.Download Pro Android C++ with the NDK Book in PDF, Epub and KindleĪndroid is one of the major players in the mobile phone market. Now extract all these files and folders to /opt/android-sdk/ndk-bundle.Ĥ. Open the zip, and open the android-ndk-r12b-linux-x86_64 (or similar) folder present inside.ģ. Android Studio looks for NDK at: /opt/android-sdk/ndk-bundleĢ. I am amazed that official Android dev section did not bother indicating exact install location of Android NDK. Installing NDK in /opt/android-sdk/ndk-bundle ![]() ![]() This time, I let the virtual Linux machine stay on foreground. I restarted Linux and restarted NDK install the same way. Later, I guess memory/page swapping occurred. My download speed was slow, so I minimized the virtual linux's window and continued to read news. Unfrotunate that there is no resume/recheck function to resurrect broken installs. I ran the NDK install from within AndroidStudio again. Size of /tmp is not dependent on free space in our hard disk (whether virtual or physical). For development purposes, I guess we should readily extend our /tmp because we will have to do it anyway some time later. Before you get started make sure that you have downloaded the latest Android SDK and upgraded your applications and environment as needed. Once I did, my /tmp was extended to 8GB size. Installing the NDK on your development computer is straightforward and involves extracting the NDK from its download package. So, only change the "size" value, by raising it by a few GBs. If any such line exists, it means you had already extended your /tmp and it was still insufficient. Note: If no such line exists, add above line at end of fstab. I appended this line to my fstab none /tmp tmpfs size=8G 0 0 I edited my fstab as root, using this command : sudo nano /etc/fstab Install NDK using Android Studio's built-in SDK manager ->not so convenient tmp is mounted usually by using 50% of available RAM. Turns out that most Linux distros have ramdisk baesd tmpfs (temporary file system in RAM which is mounted at /tmp) and there is no separate partition which could be extended. Download failed because there was no space in /tmp. I used AndroidStudio's built-in SDK manager, to try installing NDK. But I guess my instructions should be the same for any linux distribution. I have androidBBQ which is archlinux based, installed using vmware.
