Process finished with exit code -1

It couldn't load the .so file.

When I use

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

it cause java.lang.UnsatisfiedLinkError: no libamapv304 in java.library.path

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

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 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
    }
    ...
}

Support libraries that package native libraries

Summary

1. Disable load so in your app code.

2. Porting Dynamic Link Library.

If you use the Linux operating system that is the most simple, just get the x86-64(Depending on your cpu architecture) 's so file, and add the dependency so library(Found in the ndk-bundle, platforms folder).
If you use the masOS operating system, you need to do a little more work. And you should have the native so library source code, and compile it under macOS system:

``` Bash

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

get xxx.dylib

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

```
