平台android NDK不支持ABI [armeabi，mips]

Question

我在我的项目中使用JNI代码，abiFilters如下所示

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.intel.hellojni"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags ""
            }
        }
        ndk {
            abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:+'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

它在一个系统中工作正常，但是将代码移至另一个系统后，在导入时显示以下错误，我检查了新创建的项目是否存在相同的错误

ABIs [armeabi, mips] are not supported for platform. Supported ABIs are [armeabi-v7a, arm64-v8a, x86, x86_64].

如果我删除armeabi并mips像下面这样就可以了

ndk {
       abiFilters "armeabi-v7a", "x86"
}

我已经为Android Studio安装了CMake和NDK。

Answer 1

如消息所示，NDK不再支持这些ABI。NDK r17 changelog中提到了这一点：

对ARMv5（armeabi），MIPS和MIPS64的支持已删除。尝试构建任何这些ABI都会导致错误。

正如其他人所说，针对这些ABI中的任何一个，没有大量的设备可以从中受益。
