Android Studio CMake Error: Build Command failed

问题:

I'm running into an Error when I open a new project in Android Studio from the Code Samples (Hello JIN). When the Project is opened the following:

Build command failed.

回答1:

Build -> Refresh Linked C++ Projects resolved this error for me.

回答2:

@rpurohit was nearly right, Clang isn't working properly. But to change the Compiler you need to change build.gradle, in my build.gradle it was Line 12:

apply plugin: 'com.android.application'

1 android {
2    compileSdkVersion 25
3    buildToolsVersion '25.0.2'
4    defaultConfig {
5       applicationId 'com.example.hellojni'
6       minSdkVersion 23
7       targetSdkVersion 25
8       versionCode 1
9       versionName "1.0"
10      externalNativeBuild {
11          cmake {
12              arguments '-DANDROID_TOOLCHAIN=clang' --> gcc
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
        }
    }
    productFlavors {
        arm7 {
            // in the future, ndk.abiFilter might also work
            ndk {
                abiFilter 'armeabi-v7a'
            }
        }
        arm8 {
            ndk {
                abiFilters 'arm64-v8a'
            }
        }
        arm {
            ndk {
                abiFilter 'armeabi'
            }
        }
        x86 {
            ndk {
                abiFilter 'x86'
            }
        }
        x86_64 {
            ndk {
                abiFilter 'x86_64'
            }
        }
        mips {
            ndk {
                abiFilters 'mips', 'mips64'
            }
        }
        universal {
            ndk {
                abiFilters 'mips', 'mips64', 'x86', 'x86_64'
            }
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:25.2.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.1'
}

回答3:

I would recommend using GCC instead of clang for the time being because clang still does not contain all features. You can change your compiler by doing the following:

set(CMAKE_C_COMPILER /path-to-ndk/toolchains/aarch64-linux-android-4.9/prebuilt/darwin-x86_64/bin/aarch64-linux-android-gcc)

However, the darwin-x86_64 directory only exists if you are on a Mac. If you are on another platform, just use the directory that exists under the prebuilt folder.

回答4:

I found this Solution Online and this worked, however there was no explanation on how it worked: Remove the following block of code from you build.gradle file:

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

回答5:

In case previous answer doesn't work for you, as it happened to me, try to fix permissions in the bin folder of cmake and for ndk. In my case: C:\android-sdk\cmake\3.6.4111459\bin and c:\android-sdk\ndk-bundle

In my case Users group did had no permissions so Android Studio wasn't able to run cmake. Make sure it has Read and execution permissions.

回答6:

This error sometimes occurs when you upgrade gradle or other dependencies. a simple solution is Build > "Refresh linked C++ project" and after that rebuilding your project. everything goes right

回答7:

I tried the solutions provided above but no luck. Then I changed the path of OpenCV_DIR which was set in the CMakeLists.txt file and it worked. My project was not pointing to the right path, which was causing the error. Make sure you have provided the right path in your CMakeLists.txt file.

For example :

set(OpenCV_DIR "...../OpenCV_Android/install/sdk/native/jni/abi-arm64-v8a")

回答8:

I encountered this problem because I set the wrong path of native-lib.cpp. After changing

add_library(native-lib SHARED native-lib.cpp)

to

add_library(native-lib SHARED src/main/jni/native-lib.cpp)

it worked again.

By the way, this is part of my project's structure.

CMakeLists.txt
src
 |__main
      |___jni
           |___native-lib.cpp
