处理以退出代码-1

结束

它无法加载.so文件。

当我使用

时

try {      
    System.loadLibrary("libamapv304");
    System.loadLibrary("libamapv304ex");
} catch (UnsatisfiedLinkError e) {
    e.printStackTrace();
}

导致java.lang.UnsatisfiedLinkError: no libamapv304 in java.library.path

如何使用.so使用Roboletric完成单元测试？

Answer 1

我会以某种受控方式加载本机库。为简单起见，我们假设它位于Application：

public class NativeLibApplication extends Application {
    ...
    protected void loadNativeLibraries() {
        try {      
            System.loadLibrary("libamapv304");
            System.loadLibrary("libamapv304ex");
        } catch (UnsatisfiedLinkError e) {
            ...
        }
    }
    ...
}

Robolectric 让您可以在测试中调整您的应用程序。您应该在test文件夹下的同一个包中创建TestNativeLibApplication并禁止加载本机库：

public class TestNativeLibApplication extends NativeLibApplication {
    ...
    @Override
    protected void loadNativeLibraries() {
        //do nothing
    }
    ...
}

Answer 2

支持打包本机库的库

摘要

<强> 1。在您的应用代码中禁用加载。

<强> 2。移植动态链接库。

如果您使用最简单的Linux操作系统，只需获取x86-64(Depending on your cpu architecture)的so文件，然后添加依赖项库（在ndk-bundle，platforms文件夹中找到）。
如果您使用masOS操作系统，则需要做更多的工作。你应该拥有原生的库源代码，并在macOS系统下编译它：

```Bash

的.o

cc -c -I / System / Library / Frameworks / JavaVM.framework / Headers * .cpp

得到xxx.dylib

g ++ -dynamiclib -undefined suppress -flat_namespace * .o -o something.dylib

```

Windows类似。

第3。在RobolectricApplication中加载so库。

结束，运行你的测试用例，做得好：
