To set the CMake version, add the following to your module's build. Either add the path to the CMake installation to your PATH environment variable or include it in your project's local. If Gradle is unable to find the version of CMake you specified in your build. If you don't already have the Ninja build system installed on your workstation, go to the official Ninja website , and download and install the latest version of Ninja available for your OS. Configure each module with the version of the NDK you want it to use.
When using Android Studio 3. You may need to configure the version of the NDK in your project if one of the following is true:. You have multiple versions of the NDK installed and you want to use a specific one.
In this case, specify the version using the android. For AGP version 3. The current default NDK versions are listed in the following table:. Content and code samples on this page are subject to the licenses described in the Content License.
Binutils Silenced the "Erratum found and fixed" info messages. Introduced option --long-plt to fix an internal linker error when linking huge arm32 binaries. This problem was causing jump addresses to be calculated incorrectly for very large dynamic shared objects DSOs. For more information about this release, see GDB News. Fixed a number of bugs in the ndk-gdb. For more information, see Issue Those platforms still have the Android 5.
Added an optional package name argument to the ndk-gdb command --attach option. Issue 13 Fixed invalid toolchain paths for bit Windows platform.
Issue 45 Fixed the relative path for the ndk-which command. Issue 29 Fixed use of cygpath for the libgcc compiler. Changes ndk-gdb. It had regressed entirely in r Added more top-level shortcuts for command line tools: ndk-depends. This command had been entirely absent from previous releases. Fixed help documentation for --toolchain in make-standalone-toolchain. This is because the version of Clang we ship is missing a bug fix for emulated TLS support. For more general Clang issues, file bugs by following the instructions on this page.
Clang has been updated to 3. This version is a nearly pure upstream Clang. Additions Clang now provides support for emulated TLS. This limitation does not apply when running on Android 6. The NDK will neither be upgrading to 5.
Maintenance for miscompiles and internal compiler errors in 4. Removals Removed GCC 4. All targets now use GCC 4. Previously, it had been synchronized with r They are instead available on GitHub. The documentation is no longer included in the NDK package. Instead, it is on the Android developer website.
Additions Added a native tracing API to android Added a native multinetwork API to android Enabled libc, m, and dl to provide versioned symbols, starting from API level Removed sed. Removed mclinker. Removed Perl. Removed from all versions of NDK libc, m, and dl all symbols which the platform versions of those libs do not support. Partially removed support for mips64r2.
The rest will be removed in the future. Other changes Changed ARM standalone toolchains to default to arm7. You can restore the old behavior by passing specifying the -target option as armv5te-linux-androideabi. Changed the build system to use -isystem for platform includes.
Warnings that bionic causes no longer break app builds. Expect support for Froyo and older to be dropped in a future release. Added the following capabilities to cpufeatures: Detect SSE4. Updated byteswap.
Fixed fegetenv and fesetenv for arm. Binutils Additions Added a new option: --pic-veneer. Removals The bit Windows package no longer contains ld. You can instead get ld. For more information on this change, see the comments here. Improved reliability of Gold for aarch The default will likely switch in the next release. GDB Removals Removed ndk-gdb in favor of ndk-gdb. Changes Updated gdb to version 7.
Improved performance. Improved error messages. Fixed relative project paths. Stopped Ctrl-C from killing the backgrounded gdbserver. Improved Windows support. Known issues x86 ASAN does not currently work. For more information, see the discussion here. For more information, see the comments here. This behavior is not a regression from r10e. Important changes: Integrated the workaround for Cortex-A53 Erratum into the aarchlinux-android For more information on this workaround, see Workaround for cortex-a53 erratum Added Clang 3.
Removed Clang 3. Removed GCC 4. Implemented multithreading support in ld. It can now link with or without support for multithreading; the default is to do it without. To compile with multithreading, use the --threads option.
To compile without multithreading, use the --no-threads option. Removed the NDK package for bit Darwin. Important bug fixes: Fixed a crash that occurred when there were OpenMP loops outside of the main thread.
Fixed a GCC 4. The pragma takes precedence. Fixed a spurious array-bounds warning that GCC 4. The warning for ARM had previously been unconditionally disabled. Fixed Clang 3. This change allows you to avoid the following linker warning Issue Fixed stlport collate::compare to return -1 and 1. Previously, it had returned arbitrary signed numbers. Fixed ndk-gdb for bit ABIs. For more information, see this page. Implemented a workaround for the GCC 4. Issue Fixed a no rule to make target error that occurred when compiling a single.
Issue Added the libatomic. The default linker remains ld. To explicitly enable ld. Made -fstandalone-debug full debug info a default option for Clang. Added the --package command-line switch to ndk-gdb to allow the build system to override the package name. Deprecated GCC 4. GCC 4. The NDK toolchain assumes a byte stack alignment.
The tools and options used by default enforce this rule. A user writing assembly code must make sure to preserve stack alignment, and ensure that other compilers also comply with this rule.
For more information on this change, see the Address Sanitizer project. This change has a number of implications, which are discussed in Developer Preview Issue These implications do not apply to shared libraries. Important bug fixes: Made more fixes related to A53 Errata in the aarchlinux-android As part of this, GCC passes a new option, --fix-cortex-a , when -mfix-cortex-a enabled by default is specified.
For more information, see this binutils message and this binutils message. The fix itself had been implemented in r10c. Also, added a prototype in stdlib. Issue Fixed stdatomic. Changed sysconf return value type from int to long. Issue Removed bash-specific code from ndk-gdb. Issue Removed bash-specific code from make-standalone-toolchain. Issue Revised documentation concerning a fix for System. Issue Fixed a problem that was preventing bit packages from extracting on Ubuntu Issue Clarified "requires executable stack" warning from ld.
Issue Android NDK r10c October Important changes: Made the following changes to download structure: Each package now contains both the and the bit headers, libraries, and tools for its respective platform. STL libraries with debugging info no longer need be downloaded separately. Changed everything previously called Android-L to the official release designation: android Updated GCC 4.
Major differences from the upstream version of GCC 4. Note that: ARM and x86 default to using the integrated assembler. If this causes issues, use -fno-integrated-as as a workaround.
Clang 3. Made it possible to enter ART debugging mode, when debugging on an Android 5. Removed support for Clang 3. Updated mclinker to 2. Specify ICF using the --icf option. Important bug fixes: Fixed an internal compiler error with GCC4. Issue Fixed an internal compiler error with GCC4. Issue Fixed incorrect code that GCC4. Issue Fixed GCC4. Disable the workaround by specifying -mno-fix-cortex-a Fixed stdatomic.
The signal. You may remove any existing definition of struct ucontext. This change restores r9d behavior; previous versions of r10 contained placeholder files. This support had been absent from r10 and r10b because those versions of GCC had been compiled with binutils It now does. This setting brings improved LTO support.
Issue Fixed an issue related to -flto with GCC 4. The error message read To compile native-codec, you must use a bit NDK package, which is where all the Android-L headers are located.
Important bug fixes: Fixed gdb 7. Issues and Fixed GCC 4. Other bug fixes: Removed stdio. Fixed atexit. Made the following fixes to the Android-L headers: Added the following functions to ctype. Changed the ptrace prototype to long ptrace int, Removed sha1. Other changes: Updated mipsel-linux-android Change list Note that: GCC 4. Clang is currently version 3. Android-L is the first level with bit support. Note that this API level is a temporary one, and only for L-preview.
An actual API level number will replace it at L-release. The cpu-features library has been updated for the ARMv8 kernel. Recompile your code with the new version. New media APIs and a native-codec sample.
An updated Android. GLES 3. Added GCC 4. STLport : Removed 5 unnecessary static initializers from the library. This change had no impact on correctness, but using the right ABI should provide slightly better performance. Cygwin: ndk-build no longer creates an empty "NUL" file in the current directory when invoked.
Cygwin: Added better automatic dependency detection. With API Level 14, you can now decode compressed audio e.
Added CCache support. This means that either one of the following two lines in your Application. This ensures that the final linking works correctly if you have prebuilt modules that depend on these features. Shortened paths to source and object files that are used in build commands. This is useful when building projects with a lot of source files, to avoid limits on the maximum command line length supported by your host operating system.
The script takes exactly the same arguments as the original ndk-build script. You should not need to install anything else to get a working build system. For example, if a top-level module foo imports a module bar , then both libfoo. Previously, only libfoo. Static library imports are now properly transitive.
For example, if a top-level module foo imports static library bar that imports static library zoo , the libfoo. HTML : Fixed typo. The minimum API level should be 9, not 8 for native activities. For example, to compile both foo. This ensures that code generated with the standalone toolchain doesn't risk to accidentally depend on a non-stable ABI symbol e.
Note that this does not change the NDK ABIs for the corresponding libraries, because each extension must be probed at runtime by the client application. The following list describes the newly supported extensions: GLES 1. A bug in the packaging script placed them in the wrong location. Fixed atexit usage in shared libraries with the x86standalone toolchain. Fixed make-standalone-toolchain. See the bug for more information.
General notes: Adds support for the x86 ABI, which allows you to generate machine code that runs on compatible xbased Android devices. Major features for x86 include xspecific toolchains, system headers, libraries and debugging support.
The new ndk-stack tool lets you translate stack traces in logcat that are generated by native code. The tool translates instruction addresses into a readable format that contains things such as the function, source file, and line number corresponding to each stack frame. Other changes: arm-eabi The r5c release addresses the following problems in the r5b release: Important bug fixes: ndk-build : Fixed a rare bug that appeared when trying to perform parallel builds of debuggable projects.
While this breaks the source API, the binary interface to the system is unchanged. This was not the case previously because the files were grouped by source extensions instead. When import-module fails, it now prints the list of directories that were searched. Increased the build speed of debuggable applications when there is a very large number of include directories in the project. Fixed an issue where a module could import itself, resulting in an infinite loop in GNU Make.
Fixed a bug that prevented the compilation of. S files were okay. The r5b release addresses the following problems in the r5 release: The r5 binaries required glibc 2. The Linux toolchain binaries now run on Ubuntu 8. Fixes a compiler bug in the arm-linux-androideabi The previous binary generated invalid thumb instruction sequences when dealing with signed chars.
The following ndk-build issues are fixed: A bug that created inconsistent dependency files when a compilation error occured on Windows.
This prevented a proper build after the error was fixed in the source code. A Cygwin-specific bug where using very short paths for the Android NDK installation or the project path led to the generation of invalid dependency files.
This made incremental builds impossible. A typo that prevented the cpufeatures library from working correctly with the new NDK toolchain. Builds in Cygwin are faster by avoiding calls to cygpath -m from GNU Make for every source or object file, which caused problems with very large source trees. The Cygwin installation now notifies the user of invalid installation paths that contain spaces. Previously, an invalid path would output an error that complained about an incorrect version of GNU Make, even if the right one was installed.
The prebuilt-common. The toolchain rebuild scripts now also support using a bit host toolchain. General notes: Adds support for native activities, which allows you to implement the Android application lifecycle in native code. Adds native support for the following: Input subsystem such as the keyboard and touch screen Access to sensor data accelerometer, compass, gyroscope, etc.
Event loop APIs to wait for things such as input and sensor events. Window and surface subsystem Audio APIs based on the OpenSL ES standard that support playback and recording as well as control over platform audio effects Access to assets packaged in an. Includes a new toolchain based on GCC 4. The binaries for GCC 4. We recommend developers that use this library to rebuild their applications then upload to Google Play to benefit from the improvements.
Adds new sample applications, native-plasma and native-activity , to demonstrate how to write a native activity. General notes: Provides a simplified build system through the new ndk-build build command. Adds support for easy native debugging of generated machine code on production devices through the new ndk-gdb command.
Adds a new cpufeatures static library with sources that lets your app detect the host device's CPU features at runtime. Adds a sample application, hello-neon , that illustrates how to use the cpufeatures library to check CPU features and then provide an optimized code path using NEON instrinsics, if supported by the CPU.
Lets you generate machine code for either or both of the instruction sets supported by the NDK. For example, you can build for both ARMv5 and ARMv7-A architectures at the same time and have everything stored to your application's final.
