it says 4 errors
anyone can please give a solution

I had the same Problem. I hope i can help u here.
Try to create a new project and change the project location. Its important, that the new project location, contain NO whitespace. Gradle cannot sync, if there is whitespace.

Android build command failed after updating Android Studio

After I updated my Android Studio it is giving me build command failed error. It gives me the following build error :

Had the same issue after the update. I did a clean build (under Build > Clean Project) then restarted android studio with the option "Invalidate and Restart" under File > Invalidate Caches/Restart. It run well after that

Build-->Refresh Linked C++ Projects
Build Project

Try to do this:
Step 1: Safely delete the build folder from app directory.
Step 2: In Android Studio, File -> Invalidate Caches / Restart
Step 3: Build -> Clean Project Then Build -> Rebuild Project. so build folder will be regenerated and hope so error is gone.

gradle build for android native project fails with "unable to open output file" error

I am trying to build an android native project using gradle. While the build passes for the architectures arm64-v8a, x86 and x86_64, it fails for armeabi-v7a with a unique error:

error: unable to open output file '/apps/temp/HttpTransferCallbackHookImpl-baaa5e.s': 'No such file or directory'
1 error generated.
ninja: build stopped: subcommand failed.
The issue here is I am able to run this command and it builds the native libraries successfully when run the machine locally, but it fails when it is run through jenkins. The other amusing thing is that it fails only for the abi armeabi-v7a and passes for all other architectures.
I have verified the user, path and environment variables like ANDROID_HOME and ANDROID_NDK_HOME which are same when I run using the command line on the machine locally and when run using jenkins.

The command was not able to open the output files in the location "/apps/temp" as this directory was not present in the slave. This temp directory present in the jenkins master and was passed to the slave which was visible in the build variable TMP_DIR. Explicitly mentioning a valid temporary directory for the jenkins slave fixed the issue.

Android Studio NDK Build command failed (Missing c Compiler?)

I have tried several days installing the NDK into Android Studio but it always gives me an error message saying that the build failed and I should install a c compiler. I installed the NDK via the SDK Manager by checking the NDK and C Make.
I have already tried completely reinstalling Android Studio and the NDK but that did not work as well -same error.
Something maybe worth mentioning is that if I do not check the C++ support during the project creation there are no errors(but no c++ support too:D).
What should I do because it kills my workflow?
Thank you very much

The target SDK is 21.Minimum SDK is 19.NDK Version: 15.0.4075724
The same code base is compiled fine in Visual Studio Android project which uses the same toolchain.

The answer is - NDK version for SDK 19 doesn't implement the whole C++11 standard in the STL. locale.h header has stubs for localeconv() method, but the library doesn't implement it.The closest Android SDK that implement localeconv() is SDK 21.This is implicitly stated in the header <locale.h>
struct lconv* localeconv(void) __INTRODUCED_IN(21) __VERSIONER_NO_GUARD;
#if __ANDROID_API__ >= 21
locale_t duplocale(locale_t) __INTRODUCED_IN(21);
void freelocale(locale_t) __INTRODUCED_IN(21);
locale_t newlocale(int, const char*, locale_t) __INTRODUCED_IN(21);
#endif /* __ANDROID_API__ >= 21 */
char* setlocale(int, const char*);
#if __ANDROID_API__ >= 21
locale_t uselocale(locale_t) __INTRODUCED_IN(21);
#endif /* __ANDROID_API__ >= 21 */
#define LC_GLOBAL_LOCALE __BIONIC_CAST(reinterpret_cast, locale_t, -1L)
__END_DECLS
#endif /* _LOCALE_H_ */

For me, trying to use Lua 5.4.0, I have to define the API level to 21
Cmake file as:
set(ANDROID_NATIVE_API_LEVEL 21)

I had a similar problem, and unfortunaletly changing API level couldn't work for me --I was working with an old tablet which runs API16. You can try Crystax NDK or you can write an ugly function that mimics the localeconv(). The latter had solved my problem since I was building Lua for Android Terminal Emulator for hobby.
