Unable to find CMake in Android Studio

Question

I need to add C/C++ code in my Android program for which I needed LLDB, CMake, and NDK. I found LLDB and NDK in SDK manager, but CMake is missing from there. I tried manuall

Answer 1

For me, mac OS Android studio. in File->Project Structure-> Project, I changed Gradle version to 4.4 and Android plugin version to 3.1.0, then it gets good.

Plus, you can also change Android plugin version in gradle-> classpath 'com.android.tools.build:gradle:3.1.0'

Answer 2

In my case (Android Studio 3.0), there was no CMake in the "SDK Tools" tab in "Appearance & Behaviour -> System Settings -> Android SDK" options. However I noticed that in the "SDK Update sites" tab, there are only two entries, one of which (Android Repository https://dl.google.com/android/repository/repository2-1.xml) had a red mark in the "enabled" column. It read "error 407" on mouseover, which is a proxy authentication error. I had the correct proxy settings (test connection worked fine with the same repository URL), so this was very strange. Restarting android studio didn't help. So I added a new entry with the same repository and this time it worked fine and CMake appeared in the other tab. Hope this helps someone.

Check this, I think this site explains what you need:

https://codelabs.developers.google.com/codelabs/android-studio-cmake/index.html?index=..%2F..%2Findex#0

Remember to check the "What you'll need"

Update:

NDK: https://developer.android.com/ndk/downloads/index.html source: https://developer.android.com/ndk/index.html

CMake: https://cmake.org/files/v3.7/cmake-3.7.1-win64-x64.zip source: https://cmake.org/

LLDB (Just for Debian systems): http://apt.llvm.org/ source: http://lldb.llvm.org/download.html

Once you download these files, copy to your SDK folder (normally in: "C:\android-sdk\") You can localize the folder here:

1. File -> project Structure into Project Structure
2. Left -> SDK Location

Then you can continue with the previous guide after the downloads :)

Answer 4

• Open SDK Manager
• Switch to the SDK Tools tab
• Install CMake

Answer 5

For me what solved as taking off the "version" option in my gradle

 externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            //version was here
        }
    }

Answer 6

place path of the module where your cmake is exist

if your cmake exist in app main

 externalNativeBuild {
                cmake {
                        path "CMakeLists.txt"
                      }
            }

if your cmake exist in any module

  externalNativeBuild {
                cmake {
                    path file('../modulelib/CMakeLists.txt')
                }
            }

where "modulelib" is your library module folder name
