Question

我不得不在Android 15上使用旧智能手机进行编程。我使用Android Studio来执行此操作。当我编译我在较新的smarphone上使用的版本时，我得到了错误：

Error:FAILURE: Build failed with an exception.

* What went wrong:

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

似乎posix_memalign存在问题。怎么可能这样呢？

编辑我想在Android 4.0中使用Android 4.0中的智能手机。应该是什么参数？

compileSdkVersion 19
    buildToolsVersion '19.1.0'
    defaultConfig {
        applicationId "com.example.cyclopus.nativecpp"
        minSdkVersion 15
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags ""
            }
        }
    }

旧手机上的编译错误
