我有一个工作的Android webview应用程序，我用Android Studio，我需要让它打开外部包含“_blank”的链接.我添加了下面的代码

@Override
        public boolean onCreateWindow(WebView view, boolean dialog, boolean userGesture, android.os.Message resultMsg)
        {
            WebView.HitTestResult result = view.getHitTestResult();
            String data = result.getExtra();
            Context context = view.getContext();
            Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(data));
            context.startActivity(browserIntent);
            return false;
        }

但是代码“@Override”的第一行显示了下面的错误

> Task :app:compileDebugJavaWithJavac FAILED
...\MainActivity.java:58: error: method does not override or implement a method from a supertype
        @Override
        ^
Note: ...\MainActivity.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 error

以下是完整的“MainActivity”代码

import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity implements Main_Activity, Main__Activity {
    WebView webView;
    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        webView = findViewById(R.id.web);
        webView.getSettings().setJavaScriptEnabled(true);

        webView.getSettings().setUseWideViewPort(false);
        webView.setWebViewClient(new WebViewClient() {
        });
        webView.loadUrl("file:///android_asset/app.html");
    }
    public class myWebViewClient extends WebViewClient{
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            webView.loadUrl("file:///android_asset/error.html");
        }
        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
            super.onReceivedSslError(view, handler, error);
            handler.cancel();
        }
        @Override
        public boolean onCreateWindow(WebView view, boolean dialog, boolean userGesture, android.os.Message resultMsg)
        {
            WebView.HitTestResult result = view.getHitTestResult();
            String data = result.getExtra();
            Context context = view.getContext();
            Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(data));
            context.startActivity(browserIntent);
            return false;
        }
    }
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
            webView.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
}

我已经尝试了几个位置的代码，但错误仍然存在。我想摆脱错误，并实现的原因，我添加了代码;在webview应用程序外打开目标”_blank”。
