I Want to get the value of resPG from webview after it load this page
<script> $(document).ready(function(){ var resPG = {status: '<?php echo $status;?>', msg: '<?php echo $msg;?>', trans_no: '<?php echo $Tran_ID;?>', pay_amt: '<?php echo $Amount;?>', pg_type: '<?php echo $Tran_Type;?>', billno: '<?php echo $RRN;?>', PAN: '<?php echo $PAN;?>'}; localStorage.setItem('resPG', JSON.stringify(resPG)); }); </script> you need to create a Javascript interface for get values from web to android native. for working example click this link
step1) Enable webview setting
WebView mWebView = findViewById(R.id.myWebView); mWebView.getSettings().setJavaScriptEnabled(true); mWebView.setWebChromeClient(new MyWebChromeClient((Activity)mContext)); mWebView.addJavascriptInterface(new testClass(), "jsinterface"); mWebView.loadUrl("UrlToLoad"); create interface :
public class testClass{ public testClass() { } @JavascriptInterface public void getvalues(value) { Log.i('web view value',value) } } step 3: add interface function inside JS
$(document).ready(function(){ var resPG = {status: '<?php echo $status;?>', msg: '<?php echo $msg;?>', trans_no: '<?php echo $Tran_ID;?>', pay_amt: '<?php echo $Amount;?>', pg_type: '<?php echo $Tran_Type;?>', billno: '<?php echo $RRN;?>', PAN: '<?php echo $PAN;?>'}; localStorage.setItem('resPG', JSON.stringify(resPG)); jsinterface.getvalues(resPG ); }); another way is for better handling
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) { webView.evaluateJavascript("{status: '<?php echo $status;?>', msg: '<?php echo $msg;?>', trans_no: '<?php echo $Tran_ID;?>', pay_amt: '<?php echo $Amount;?>', pg_type: '<?php echo $Tran_Type;?>', billno: '<?php echo $RRN;?>', PAN: '<?php echo $PAN;?>'};", new ValueCallback<String>() { @Override public void onReceiveValue(String s) { contentView.setText(s); } }); } else { webView.loadUrl("javascript:window.jsinterface.getvalues({status: '<?php echo $status;?>', msg: '<?php echo $msg;?>', trans_no: '<?php echo $Tran_ID;?>', pay_amt: '<?php echo $Amount;?>', pg_type: '<?php echo $Tran_Type;?>', billno: '<?php echo $RRN;?>', PAN: '<?php echo $PAN;?>'};)"); } 
You can use JavaScript scheme in web-view load URL something like below
webview.loadUrl("javascript:Android.getMyData(MyData);"); //Add the javascript interface to your web view this.addJavascriptInterface(new MyJavaScriptInterface(webViewContext), "Android"); public class MyJavaScriptInterface{ Context mContext; /** Instantiate the interface and set the context */ CustomJavaScriptInterface(Context c) { mContext = c; } /** retrieve the data */ public void getMyData(final String myData) { //Do somethings with the Data }
