Android studio 将Android ndk应用程序迁移到Android Studio（gradle实验版0.2.0）

我试图根据将现有ndk项目转换为Android Studio，但无法解决所有错误

现在我得到以下错误：

/home/nxp/Documents/Projects/Android_Ucode_demo/app/src/main/jni/ECDSA-jni.c 
Error:(44, 30) openssl/ossl_typ.h: No such file or directory

简单的方法是迁移NDK项目。不要导入项目。请使用完全相同的包名复制您的文件，并在依赖项中添加支持库。正确地进行gradel同步，支持最小值和最大值。

您可以充分享受ndk build的强大功能，并在Android Stidio中获得带有本机调试的实验级插件的支持，请参见错误是因为src/main/jni/include不在include路径内，请使用
addAll（['-I'+文件（'src/main/jni/include'）） 示例见
主要是因为androidstudio/gradle递归编译源文件，但它不会在包含路径的过程中添加子目录；您需要手动处理它

希望您没有使用libcrypto static.a：静态库需要支持不同的ABI[检查您现有的应用程序.mk]，因此一个库将为不同的ABI提供不同的二进制文件。这是很好的建立自己和使用；Teapot将本机应用程序glue构建为静态库，并在本地使用它。libECDSA.so也是如此；除非你只为一种armeabi风格而构建，否则Android Studio会抱怨找不到其他ABI库。您可以在同一回购协议中检查hello LIB

说到lib的使用，cmake要简单得多。如果您选择，示例在同一回购协议中，即master cmake分支
