我是Android NDK的新手，我目前正在尝试为Android（以及后来的iOS）构建RTMP C客户端。目前，我遇到了一个问题，一旦我尝试加载我的库，应用程序崩溃了：
static {
System.loadLibrary("test");
}
我得到的例外是
java.lang.UnsatisfiedLinkError: dlopen failed: could not load library "librtmp.so.1" needed by "libtest.so"; caused by library "librtmp.so.1" not found
老实说，我完全迷失了。 ndk-build不会返回任何错误：
[armeabi] Prebuilt : rtmp.so <= jni/rtmp/
[armeabi] Install : rtmp.so => libs/armeabi/rtmp.so
[armeabi] Compile thumb : test <= RTMPClient.c
[armeabi] SharedLibrary : libtest.so
[armeabi] Install : libtest.so => libs/armeabi/libtest.so
我尝试通过System.loadLibrary("rtmp")加载rtmp图书馆，但没有骰子。
Android.mk
LOCAL_PATH:= $(call my-dir)
LIBS_PATH := libs/$(TARGET_ARCH_ABI)
include $(CLEAR_VARS)
LOCAL_MODULE := rtmp
LOCAL_SRC_FILES := rtmp/rtmp.so
LOCAL_C_INCLUDES := rtmp/
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := test
LOCAL_SRC_FILES := RTMPClient.c
LOCAL_LDLIBS := -llog
LOCAL_SHARED_LIBRARIES += rtmp
include $(BUILD_SHARED_LIBRARY)
Application.mk
APP_PLATFORM:=android-19
我的RTMPClient.c使用rtmp中的一些结构和函数，如下所示：
#include <rtmp/rtmp.h>
我不确定librtmp.so.1来自哪里，但我也发现它在我的libtest.so中使用arm-linux-andrioideabi-readelf：
0x00000001 (NEEDED) Shared library: [librtmp.so.1]
关于如何解决此问题的任何想法？
编辑：我从here获得了rtmp.so文件。我是从the KODI librtmp update page
寄来的答案 0 :(得分：0)
我最终抛弃了我的rtmp.so文件，而是从rtmpdump-android抓取了jni文件。放入这些文件后，将我的android.mk文件更改为：
#include "librtmp/rtmp.h"将我的RTMPClient.c文件更改为包含#include <rtmp/rtmp.h>而不是"use strict";

，该文件已编译并在我的设备上运行，没有任何问题。
