Question

我在我的项目中使用预建的openssl。加载应用程序崩溃并发出此错误

java.lang.UnsatisfiedLinkError: dlopen failed: could not load library "libcrypto.so.1.0.0" needed by "libPrivateSsl.so"; caused by library "libcrypto.so.1.0.0" not found

我的android.mk看起来像这样

LOCAL_PATH := $(call my-dir)

# Prebuilt libssl
include $(CLEAR_VARS)
LOCAL_MODULE := ssl
LOCAL_SRC_FILES := precompiled/libPrivateSsl.so
include $(PREBUILT_SHARED_LIBRARY)

# Prebuilt libcrypto
include $(CLEAR_VARS)
LOCAL_MODULE := crypto
LOCAL_SRC_FILES := precompiled/libPrivateCrypto.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := myLibrary
TARGET_PLATFORM := android-3
LOCAL_SRC_FILES := native-lib.cpp
LOCAL_C_INCLUDES = $(LOCAL_PATH)/include
LOCAL_LDLIBS := -llog
LOCAL_SHARED_LIBRARIES := ssl crypto


include $(BUILD_SHARED_LIBRARY)

在像这样的活动中加载库

static {
    System.loadLibrary("PrivateSsl");
    System.loadLibrary("PrivateCrypto");
    System.loadLibrary("myLibrary");

}

我使用Kit-kat进行Ubuntu系统测试。请帮我解决这个错误。

Answer 1

您下载了一些错误的OpenSSL for Android版本，该版本未正确构建（类似于this one。Android does not support versioning in SONAMEs。

您可以找到更好的预建版OpenSSL，但不建议这样做。为了将这些库委托给您的秘密通信，您应该更好地确保自己从受信任的（official）源构建它，并且它不会将您的私人信息泄漏给某个流氓第三方。

作为最低限度修复，您可以try to use patchelf 实用程序来修复库中的SONAME。

我通过在android.mk文件中进行一些小改动来解决这个问题

我删除了.so文件并放置了.a文件。

我的android.mk现在看起来像这样

  LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := ssl_static
LOCAL_SRC_FILES := precompiled/libssl.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := crypto_static
LOCAL_SRC_FILES :=precompiled/libcrypto.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := myLibrary

LOCAL_SRC_FILES := native-lib.cpp
LOCAL_C_INCLUDES = $(LOCAL_PATH)/include
LOCAL_LDLIBS := -llog
LOCAL_STATIC_LIBRARIES := ssl_static crypto_static
include $(BUILD_SHARED_LIBRARY)

got this idea from here
