在 Android Studio gradle 项目中使用 NDK 和 STL [英] Using NDK with STL in Android Studio gradle project

问题描述

我在将 stlport 链接到 Android Studio 中的 gradle 项目时遇到问题.

I have a trouble with linking stlport into gradle project in Android Studio.

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

Eclipse Android project with using NDK migrates into Android Studio.

该项目使用 STL，我有包含内容的 android.mk 文件

The project uses STL and I have android.mk file with contents

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)

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

It seems gradle to ignore .mk file, and I added the folowing code into build.gradle file:

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:

After this gradle building became successful, but running the application on device causes an error:

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

推荐答案

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，请改为指定 stlport_static:

You need to load the stlport shared library manually in your Java code if you are using the shared variant. If you do not need the shared variant, specify stlport_static instead:

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