android - 无法访问我在 android 中的模块嵌套依赖项

Question

我创建了一个具有如下类依赖项的 android 模块:

implementation 'com.squareup.moshi:moshi:1.5.0'
implementation 'com.neovisionaries:nv-websocket-client:2.3'

我将此模块添加到我的项目中。当我想使用它时，它说“无法访问 com.neovisionaries.Adapter”。

1 -Why it cannot access because I think that my Async class calls the method in the background?

2-Should I add that dependency to my project?

我的模块类

public class Async extends WebSocketAdapter {
   ....
public Async() {
}

public static Async getInstance(Context context) {
    if (instance == null) {
        sharedPrefs = context.getSharedPreferences(AsyncConstant.Constants.PREFERENCE, Context.MODE_PRIVATE);
        moshi = new Moshi.Builder().build();
        instance = new Async();
    }
    return instance;
}


public void webSocketConnect(String socketServerAddress, final String appId) {
        WebSocketFactory webSocketFactory = new WebSocketFactory();
        webSocketFactory.setVerifyHostname(false);
        setAppId(appId);
        setServerAddress(socketServerAddress);
        try {
            webSocket = webSocketFactory
                    .setConnectionTimeout(TIMEOUT)
                    .createSocket(socketServerAddress)
                    .addListener(this);
            webSocket.connectAsynchronously();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }}

MyPresenter 类

public class SocketPresenter implements SocketContract.presenter {

private Async async;
private SocketContract.view view;
@Override
    public void connect(String socketServerAddress, String appId) {
        async.webSocketConnect(socketServerAddress, appId);
    }

此行有一个错误 async.webSocketConnect(socketServerAddress, appId); 表示 websocketConnect 无法访问我的嵌套模块依赖项。

当 Gradle compile 关键字被弃用时，它被两个新关键字取代:implementation 和 api。 implementation 关键字将您的依赖关系保持在内部，而 api 像旧的 compile 关键字一样公开它们。因此，您应该使用 api 而不是 implementation。
