未从Cordova APK下载本地库 [英] Native library not loaded from cordova apk
问题描述
我正在制作一个cordova插件,它将是.jar文件及其两个.so依赖项的简单包装.我之前在带有android studio的普通android应用程序中尝试过.通过将本机库复制到jniLibs/armeabi文件夹中,并将jar文件复制到libs/中,它可以正常工作.
在cordova插件中,我制作了相同的文件夹结构,并且所有内容都位于同一位置.在plugin.xml中,我已将两个文件复制到libs/armeabi中,这是可以正常工作的,因为如果我查看apk,它们将位于正确的"文件夹中.
但是,当我尝试使用cordova应用程序中的插件时,尝试调用本机库时会引发UnsatisfiedLinkError:
java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.ionicframework.*******-2/base.apk"],nativeLibraryDirectories=[/data/app/com.ionicframework.*******-2/lib/arm, /vendor/lib, /system/lib]]] couldn't find "libjni.so"

我应该在哪里复制这些库?
我最近需要交叉编译一个C库以用于Cordova应用程序,因此,基于该经验,我创建了一个示例Cordova插件和相应的插件. xml ,您还将看到我还将armeabi
库以及其他库用于其他体系结构复制到了/libs/armeabi
.
该插件肯定可以正常工作(您可以尝试),因此希望您可以将其用作有效参考.
愚蠢的问题:您不是只复制 armeabi
库吗?因为我敢肯定大多数现代Android设备都不支持(ARMv5/ARMv6),并且要求armeabi-v7a
必须位于/libs/armeabi-v7a

I'm making a cordova plugin that would be a simple wrapper for a .jar file and its two .so dependencies. I have tried it before in a normal android application with android studio. By copying the native libraries into the jniLibs/armeabi folder and the jar file into libs/ it worked perfectly.
At the cordova plugin I've made the same folder structure and everything is on the same place. In the plugin.xml I have copying the two files into libs/armeabi which is working because if I look into the apk, they are in the "right" folder.
But when I try to use the plugin from the cordova application it throws an UnsatisfiedLinkError when it tries to call the native library:
java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.ionicframework.*******-2/base.apk"],nativeLibraryDirectories=[/data/app/com.ionicframework.*******-2/lib/arm, /vendor/lib, /system/lib]]] couldn't find "libjni.so"

Where should I copy these libraries?
I've recently needed to cross-compile a C library for use in a Cordova app, so based on that experience, I've created an example Cordova plugin and corresponding test app that uses it.
If you look in my plugin.xml you'll see I also copy the armeabi
library to /libs/armeabi
, as well as the other libraries for the other architectures.
That plugin is definitely working (you can try it), so hopefully you can use it as a working reference.
Stupid question: you're not copying only the armeabi
library? Because I'm pretty sure most modern Android devices don't support that (ARMv5/ARMv6) and require armeabi-v7a
to be in /libs/armeabi-v7a
