Bundle extras = getIntent().getExtras();
url = extras.getString("redirect_url");
final ProgressDialog pd = ProgressDialog.show(OnlinePayment.this, "", "Redirecting...", true);
Log.e("Here redirect first", url);
online_payment_activity_web_view=(WebView) findViewById(R.id.online_payment_web_view);
online_payment_activity_web_view.getSettings().setjavascriptEnabled(true);

【问题讨论】：
MyMasterPiece 的回答对我有用 ***.com/questions/18377769/… Webview not able to load https url in android?的可能重复 【参考方案1】：你应该使用
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
view.loadUrl(url);
return false;
请关注google official link了解更多信息。
【讨论】：
【参考方案2】：根据文档here 使用shouldOverrideUrlLoading：
Do not call WebView#loadUrl(String) with the requests URL and then return true.
This unnecessarily cancels the current load and starts a new load with the same URL.
The correct way to continue loading a given URL is to simply return false, without calling WebView#loadUrl(String).
使用 shouldOverrideUrlLoading(Webview view, String url) 从 API 24 开始已弃用，应改为使用 shouldOverrideUrlLoading(Webview, WebResourceRequest)
