android - Android NDK 平台不支持 ABI [armeabi, mips]

Question

我在我的项目中使用 JNI 代码和 abiFilters 如下

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，但在将代码移动到其他系统后，它显示以下导入错误，我已经检查了新创建的项目它有同样的错误

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

Build command failed.

如果我像下面那样删除 armeabi 和 mips 那么它就可以工作了

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

我已经为 android studio 安装了 CMake 和 NDK。

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

Support for ARMv5 (armeabi), MIPS, and MIPS64 has been removed. Attempting to build any of these ABIs will result in an error.

正如其他人所说，没有大量设备可以从针对这些 ABI 中的任何一个中受益。
