Android Studio的so文件无法加载

Question

最近重构之前的项目，调试时出现无法加载so文件。
我so文件放置的路径如下：

出现的错误是：

E/AndroidRuntime: FATAL EXCEPTION: main
  Process: net.comet.example, PID: 6786
  java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/net.comet.example-1/base.apk"],nativeLibraryDirectories=[/data/app/net.comet.example-1/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libZBarDecoder.so"

错误里显示的路径中包名后面多了一个 -1 ，不知道怎么回事，我仔细检查了下，发现工程里的包名没有 -1 才对！

我又重新建了一个空的工程，然后把这些文件和部分代码拷贝过去，运行却正常。

百思不得其解，所以上来请教了！

Answer 1

This problem has been solved because my project integrates Tencent bugly. If I use the method of automatically importing bugly, the code will not find other third-party so files when running; if I use the method of manually importing the bugly jar package , there is no such problem. It should be a bug of bugly!

Answer 2

The extra -1 in the package name in the log is normal. Your exception is in
nativeLibraryDirectories=[/data/app/net.comet.example-1/lib/arm64, /vendor/lib64, / system/lib64]]] couldn't find "libZBarDecoder.so"
The library libZBarDecoder.so was not found.
There are two suggestions
1. Copy libZBarDecoder.so to the armeabi-v7a directory
2. Add jniLibs declaration in app.gradle

android{
    ...
    sourceSets {
        main {
          jniLibs.srcDirs = ['libs']
        }
    }
    ...
}

If it doesn’t work, let’s analyze it in detail
