android – 如何在使用Robolectric时加载.so？

W / Environment：EXTERNAL_STORAGE undefined;回到默认状态

java.lang.UnsatisfiedLinkError: com.autonavi.amap.mapcore.MapCore.nativeNewInstance(Ljava/lang/String;)J

进程以退出代码-1结束

它无法加载.so文件.

我用的时候

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

它会导致java.lang.UnsatisfiedLinkError：java.library.path中没有libamapv304

如何使用.so完成Roboletric的单元测试？

最佳答案

我会以某种受控方式加载本机库.为简单起见,假设它在应用程序中：

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
    }
    ...
}
