英文:
dlopen failed for prebuilt so file at Android Studio
问题
我正在使用Android Studio制作一个应用程序。
尝试使用外部预构建的so文件时出现问题。
main/cpp/CMakeLists.txt声明如下。
add_library(ace SHARED ace.cpp)
add_library(banana SHARED IMPORTED)
set_target_properties(banana PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}/libbanana.so)
target_link_libraries(ace banana)
然后我得到了以下错误。
java.lang.UnsatisfiedLinkError: dlopen失败：找不到库“app/src/main/cpp/../jniLibs/arm64-v8a/libbanana.so”：由/data/app/~~H6athrEZA==/com.test1T_dd6A==/base.apk！/lib/arm64-v8a/ace.so所需。
我将libbanana.so放在了main/jniLibs/arm64-v8a目录下。
我还设置了以下build.gradle。
ndk {
abiFilters 'arm64-v8a'
}
在以下路径中也确认了libbanana.so。
build->分析APK->文件->lib->arm64-v8a。
如果我删除与libbanana相关的内容，它可以工作，但是
我的目标是使用预构建的libbanana.so。
有人知道问题是什么吗？
我添加了一些测试。
我添加了另一个so文件，但没有错误。
如何使so文件正常工作？
英文:
I am making an app with android studio.
There is a problem trying to use external prebuilt so.
main/cpp/CMakeLists.txt was declared as follows.
add_library(ace SHARED ace.cpp)
add_library(banana SHARED IMPORTED)
set_target_properties(banana PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}/libbanana.so)
target_link_libraries(ace banana)
And then I get the following error.
java.lang.UnsatisfiedLinkError: dlopen failed: library "app/src/main/cpp/../jniLibs/arm64-v8a/libbanana.so" not found: needed by /data/app/~~H6athrEZA==/com.test1T_dd6A==/base.apk!/lib/arm64-v8a/ace.so in namespace
I put the libbanana.so to the main/jniLibs/arm64-v8a.
I also set the build.gradle below.
ndk {
abiFilters 'arm64-v8a'
}
Libbanana.so was also confirmed in the path below.
build->Analyze APK-> File->lib->arm64-v8a.
If I remove the contents related to libbanana, it works, but
My goal is to use prebuilt libbanana.so.
Does anyone know what the problem is?
I added a few tests.
I put in another so file, but there is no error.
how to make the so file is normal?

-
尝试了3次后解决了。
-
如果在想要使用的"A so文件"中使用了另一个"B so文件"，则必须在AndroidManifest.xml中指定"B so文件"已经存在于设备中。
<uses-native-library android:name="libb.so" /> -
将so文件添加到/vendor/etc/public.libraries.txt。
英文:
It was resolved after 3 attempts.
-
Change the build method of so file to NDK
-
If another 'B so file' is used in the 'A so file' you want to use, you must specify in AndroidManifest.xml that the 'B so file' already exists in the device.<br>
<uses-native-library android:name="libb.so" /> -
Add so file to /vendor/etc/public.libraries.txt
