进程退出代码为-1

无法加载.so文件.

当我使用

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

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

如何使用.so完成Roboletric的单元测试?

How can I using .so to complete unit test with Roboletric?

推荐答案

我将以某种受控方式加载本机库.为了简单起见，假设它在Application中:

I would load native libraries in some controlled way. For simplicity let assume it is in Application:

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

Robolectric 使您可以调整测试中的应用程序.您应该在测试文件夹下的同一包中创建TestNativeLibApplication，并禁止加载本机库:

Robolectric gives you a possibility to tweak your application under the test. You should create TestNativeLibApplication in the same package under test folder and suppress loading native libraries:

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