如何在Android Studio中导入两个jni模块？

Question

android {
defaultConfig {
    ndk {
        moduleName "p7zip"
        abiFilters "armeabi", "armeabi-v7a"
    }
    ndk {
        moduleName "CryptUtils-jni"
        abiFilters "armeabi", "armeabi-v7a"
    }
}

}

它给出了错误消息“引起：java.lang.UnsatisfiedLinkError：无法从loader dalvik.system.PathClassLoader加载CryptUtils-jni [dexPath = / data / app / com.pncmicros.banksia.mediaplayer.client -2.apk，libraryPath = / data / app-lib / com.pncmicros.banksia.mediaplayer.client-2]：findLibrary返回null“ 我就像下面的jni文件夹：

Android.mk文件写得像这样：

include $(call all-subdir-makefiles)

Android.mk文件夹“CryptUtils” https://dl.dropboxusercontent.com/u/9927654/CryptUtils-Android.mk

Android.mk文件夹“p7zip” https://dl.dropboxusercontent.com/u/9927654/p7zip-Android.mk
