在Android Studio gradle项目中使用NDK和STL

Question

我在将stlport链接到Android Studio中的gradle项目时遇到了麻烦.

使用NDK的Eclipse Android项目迁移到Android Studio.

该项目使用STL,我有android.mk文件的内容

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := MyProject
LOCAL_SRC_FILES := jniapi.cpp renderer.cpp
LOCAL_LDLIBS    := -llog -landroid -lEGL -lGLESv1_CM -ljnigraphics

include $(BUILD_SHARED_LIBRARY)

忽略.mk文件似乎有点儿,我将以下代码添加到build.gradle文件中:

ndk {
   moduleName "MyProject"
   stl "stlport_shared"
   ldLibs "log", "EGL", "android", "jnigraphics", "GLESv1_CM"
   //No equivalent for the "include $(BUILD_SHARED_LIBRARY)" here
}

此gradle构建成功后,但在设备上运行应用程序会导致错误:

27446-27446/com.example.test E/AndroidRuntime? FATAL EXCEPTION: main
java.lang.UnsatisfiedLinkError: Cannot load library: soinfo_link_image(linker.cpp:1635): could not load library "libstlport_shared.so" needed by "libMyProject.so"; caused by load_library(linker.cpp:745): library "libstlport_shared.so" not found

如果您使用共享变体，则需要在 Java 代码中手动加载 stlport 共享库。如果您不需要共享变体，请指定 stlport_static：

ndk {
    moduleName "MyProject"
    stl "stlport_static"
    ldLibs "log", "EGL", "android", "jnigraphics", "GLESv1_CM"
    //No equivalent for the "include $(BUILD_SHARED_LIBRARY)" here
}
