Also, this seems to be general CLion C++ breakage -- editing C++ files
no longer shows options when typing etc.  So some serious problems with
C++ typeahead and navigation which broke recently.

Error message popup after clicking native function decl in java file:
    "Cannot resolve corresponding JNI function ..."
Ctrl-hover over native function decl in java file shows popup:
    "Show usages of method ..."
but instead should present C++ JNI function decl/defn to jump to in C++ source file

Same error here, on my case:
I updated to version 2.3.0-beta2 and everything seemed fine, then updated NDK to 14.0.3529234rc1. then I restarted next time I opened my project JNI function stopped resolving just as described here. (I'm using ndkBuild)

Sorry, I'm using ndkBuild as well (not cmake)

I seem to be having same problem. After several clean installs I figured that c++ integration (navigation, code completion, structure view...) works fine even on Android Studio 2.3 Beta 3 with gradle plugin 2.3.0-beta3 as long as I do not update  use NDK version 13.

After updating to NDK 14 it stops working.

Previously other contributors to this ticket had noted that staying on
NDK 13.1.3345770 solved the symbol resolution issues.  Now that
NDK "14.0.3529234 rc1" replaced by NDK 14.0.3770861, probably worth
another look to see if this has been fixed

Unfortunately, appears this problem has _not_ been fixed in
NDK 14.0.3770861 -- after updating to this version, a lot of C++ symbols (which had
been correctly color-coded before, and were control-click navigable)
turned red, including basics like JNIEnv, jobject etc -- so same situation
as NDK 14.0.3529234rc1.

Will revert to NDK 13.1.3345770 and wait for next NDK update to try again...

Config details:

Android Studio 2.3

Project A:
Gradle plugin:
 * classpath 'com.android.tools.build:gradle:2.3.0'
Gradle version:
 * gradle-3.3-all

Project B:
Gradle plugin:
 * classpath 'com.android.tools.build:gradle:2.2.3'
Gradle version:
 * gradle-2.14.1-all

For both projects, NDK 13.1.3345770 works for C++ symbols/UI navigation,
and NDK 14.0.* doesn't work for C++ symbols/UI navigation

---BEGIN QUOTE---
Android Studio "clion" feature provides syntax highlighting, typeahead prediction,
ctrl/cmd-click navigation etc. in C++ code.

If NDK 13.1.3345770 is used, everything works properly.

But if either

NDK 14.0.3529234rc1
NDK 14.0.3770861
are used, the C++ symbol resolution/navigation features break.
As explained https://code.google.com/p/android/issues/detail?id=231382 this
is down solely to NDK version, not Android Studio/gradle/gradle plugin version.

How does CLion know where to find thngs? Any chance this is caused by the `make -n` output scanning and it was searching for only `-isystem`? r14 uses `--sysroot`.

Dan's theory seems sounds. Android Studio doesn't engage unless the target is Android. If I recall correctly, Thiru implemented both isystem and sysroot checks. However, by their nature, they are apt to be fragile.

This bug should block one these:
- NDK r14
- Android Studio 2.3

Too late, because those both just went out!

We'll need a dot or patch release on one of them. :(

Hey Alex, this is  candidate for 2.3.1. Can you take a look?

(and work out what the missing QA test is. has anyone on the Studio team reproduced this yet? tnorbye said he couldn't...)

With cmake and gradle-experimental, the combination of Android Studio 2.3 stable and NDK r14.0.3770861 is supporting navigation properly for me.

With ndkBuild (two-libs project from android-ndk github) it is not working.

I believe I have a fix on the studio side.  We were only looking for sysroot flags of the form '--sysroot=<path>', not '--sysroot <path>'.

Seems I've ran into this issue on stable Android Studio 2.3, NDK r14 and externalNativeBuild -> ndkBuild. I've downgraded NDK to r13b and all works perfect as before, so the issue is related to the changes in NDK r14.

I have complex project structure, about 10 static libraries that build into 1 shared library (include $(BUILD_SHARED_LIBRARY)) and 3 executables (include $(BUILD_EXECUTABLE)). On stable Android Studio 2.3 and NDK r14 almost all C/C++ sources begin to show "This file is not part of the project..." message. Cleaning, building, Gradle syncing doesn't help. However, it affects only syntax highlight in editor. Build and run works fine.

Also, when I was downgrading NDK to r13b, I've found that download link to NDK r13b is actually pointing to r14. So I've manually substitute version in download URL and only that way was able to download NDK r13b: https://developer.android.com/ndk/downloads/older_releases.html

Download links for r13b are fixed now:

Thanks for catching this issue!

Does anyone know if this issue has been addressed in
Android Studio 2.4 Preview 1?

It is still present in Android Studio 2.4 preview 1 with gradle plugin 2.4.0-alpha1 :-(

I just updated studio to 2.4 preview 3, android plugin to 2.4.0-alpha3 and NDK to r14b and C++ integration seems to be working again. :-)

Thanks

Using externalNativeBuild.ndkBuild with:
* Android Studio 2.4 Preview 3
* gradle 2.14.1
* gradle plugin 2.2.3
* NDK r14b (14.1.3816874)

CLion (C++) navigation/typeahead/cmd-click navigation etc looks OK, also C++ debug works (hit breakpoints)

Android Studio 2.4 Preview 3 works for me too. ctrl-click and debugging both java and cpp on emulator/device works.

I guess the official release of Android Studio 2.4 is far away. Are you considering fixing this regression in Android Studio 2.3.1?

We will have a fix for this in a stable version of studio shortly.
