Answer 1

公共类MainActivity扩展了AppCompatActivity {

private WebView abWebView;

@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    abWebView = findViewById(R.id.activity_main_webview);
    abWebView.setWebViewClient(new WebViewClient());
    WebSettings webSettings = abWebView.getSettings();

    abWebView.getSettings().setAppCacheEnabled(false);
    abWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

    abWebView.getSettings().setJavaScriptEnabled(true);

    abWebView.getSettings().setDomStorageEnabled(true);

    abWebView.getSettings().setUserAgentString(abWebView.getSettings().getUserAgentString() + " MobileAppClient/Android/0.9");

    if ( Build.VERSION.SDK_INT >= 21 ) {
        CookieManager.getInstance().setAcceptThirdPartyCookies(abWebView, true);
    }
