Error:Error occurred while communicating with CMak

Question

I'm trying to build a simple native app from Android Studio 3.0 on Windows 10. When I will try to build the app, I get the following error:

"Error:Error occurred while communicating with CMake server. Check log xxx\Native\app.externalNativeBuild\cmake\debug\armeabi-v7a\cmake_server_log.txt for additional information."

And the log contains:

"CMAKE SERVER: CMAKE SERVER: [== "CMake Server" ==[ CMAKE SERVER: {"supportedProtocolVersions":[{"isExperimental":true,"major":1,"minor":1}],"type":"hello"} CMAKE SERVER: ]== "CMake Server" ==]"

I have created the "CMakeLists.txt" as required in the official documenation..

Any suggestions on how to fix this problem? Thank you!

Answer 1

I had the same problem. This worked for me.

Goto the SDK Manager --> Android SDK --> SDK Tools --> CMake.

And install CMake from the SDK manager. Just check the images if you don't get what I mean.

Answer 2

Actually the issue is that Gradle is interpreting the debug output of the cmake-server as an error and fails. It happens with com.android.tools.build:gradle:3.0.0 but it works correctly starting with com.android.tools.build:gradle:3.1.0.

If for some reason (plugin, etc) you cannot update to 3.1.0, you can replace cmake with a python wrapper and filter the output by removing this exact output:

[== "CMake Server" ==[

{"supportedProtocolVersions":[{"isExperimental":true,"major":1,"minor":1}],"type":"hello"}

]== "CMake Server" ==]

Answer 3

I got exact same error, even with the solution from kevvex, android studio reported same error.

I compared with another working windows 10 machine and found three differences:

1. CMake is 3.10xxx is not working on my machine, CMake 3.6.4111459 is on working machine

2. OpenCV-android-sdk version 2.4.7.2 is not working on my machine, OpenCV-android-sdk version 3.2.0 is on working machine

3. android-ndk/ndk-bundle 14.1.3816874 is not working on my machine, android-ndk/ndk-bundle r15c is on working machine (This one maybe optional)

Replaced these three items, the project is built successfully on my machine.
