Android WebView没有'；无法在模拟器上加载内容

我试着阅读其他主题，但没有任何效果，所以我提出了这个新问题

我有一个包含webView的活动，但内容似乎没有加载（在emulator上，因为这是我现在唯一的“设备”）

这是我的密码： 公共类WebViewActivity扩展了AppCompatActivity{

WebView webView;
private ProgressDialog progressBar;
String link;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_web);

    // Hide action bar
    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.hide();
    }

    webView = (WebView) findViewById(R.id.webView);

    Intent intent = getIntent();
    link = (String) intent.getSerializableExtra(Constants.intentForWebView);

    progressBar = ProgressDialog.show(this,"loading","please wait");
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.setWebViewClient(new MyWebViewClient());

    webView.loadUrl(link);

}

private class MyWebViewClient extends WebViewClient {

    @Override
    public void onPageFinished(WebView view, String url) {
        if (progressBar != null && progressBar.isShowing()) {
            progressBar.dismiss();
        }
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        return super.shouldOverrideUrlLoading(view, request);
    }
}
}

问题似乎是加载没有有效证书的站点时出现的。添加在emulator中加载了证书的站点的url
您在Logcat中是否收到任何错误或警告？这就是我得到的：W/art:尝试删除非JNI本地引用，转储线程E/chromium:[错误：gles2_cmd_decoder.cc（2167）][GroupMarkerNotSet（crbug.com/242999）！：54098386]GL ERROR:GL_INVALID_OPERATION:BackFramebuffer:：Create:你能在错误消息周围发布整个logcat吗？你能将它编辑到原始问题中而不是添加为注释吗？这使得阅读更容易。我现在这样做了…将它们添加到原始post中找到了答案。因此，问题在于它没有显示如果站点证书未经验证，请访问该站点。我刚刚将serializable中的链接更改为另一个站点，该链接正常运行。感谢您的帮助：）
