![\"ERR_UNKNOWN_URL_SCHEME](\"http:\/\/mariusbancila.ro\/blog\/wp-content\/uploads\/2015\/09\/ERR_UNKNOWN_URL_SCHEME.png\")
<\/a>\nThis seem to be a known issue as I found many references of it on the web. Here are several for reference:<\/p>\n
- \n
- Android WebView “tel:” links show web page not found<\/a><\/li>\n
- Getting net::ERR_UNKNOWN_URL_SCHEME while calling telephone number from HTML page in Android<\/a><\/li>\n
- Android Webview ERR_UNKNOWN_URL_SCHEME Error<\/a><\/li>\n
- Webview shouldoverrideurlloading doesn’t work<\/a><\/li>\n<\/ul>\n
I am using the InAppBrowser<\/a> plugin to open links in external apps. In order for this to work the schemes must be white-listed in Cordova’s config.xml<\/tt> file and the launch-external<\/tt> attribute should be set to true (which was already set in my case).<\/p>\n
\r\n<access origin=\"mailto:*\" launch-external=\"true\" \/>\r\n<access origin=\"tel:*\" launch-external=\"true\" \/>\r\n<access origin=\"sms:*\" launch-external=\"true\" \/>\r\n<access origin=\"geo:*\" launch-external=\"true\" \/>\r\n<access origin=\"maps:*\" launch-external=\"true\" \/>\r\n<\/pre>\n
The indicated solution is to override WebView.shouldOverrideUrlLoading<\/a> method. <\/p>\n
I added the following in plugins\\cordova-plugin-inappbrowser\\src\\android\\InAppBrowser.java in the plugin’s WebView<\/tt> extension, but that did not work as the code did not even execute.<\/p>\n
\r\n@Override\r\npublic boolean shouldOverrideUrlLoading(WebView view, String url) {\r\n if( url.startsWith(\"http:\") || url.startsWith(\"https:\") ) {\r\n return false;\r\n }\r\n\r\n \/\/ Otherwise allow the OS to handle it\r\n Intent intent = new Intent(Intent.ACTION_VIEW);\r\n intent.setData(Uri.parse(url));\r\n cordova.getActivity().startActivity(intent);\r\n return true;\r\n}\r\n<\/pre>\nLooking for a solution I have noticed that this was only working OK for tel:<\/tt> and for others it was exhibiting this behavior. Then I found the following code in the InAppBrowser<\/tt> plugin class, in the execute()<\/tt> method.<\/p>\n
\r\n\/\/Load the dialer\r\nelse if (url.startsWith(WebView.SCHEME_TEL))\r\n{\r\n try {\r\n Log.d(LOG_TAG, \"loading in dialer\");\r\n Intent intent = new Intent(Intent.ACTION_DIAL);\r\n intent.setData(Uri.parse(url));\r\n cordova.getActivity().startActivity(intent);\r\n } catch (android.content.ActivityNotFoundException e) {\r\n LOG.e(LOG_TAG, \"Error dialing \" + url + \": \" + e.toString());\r\n }\r\n}\r\n<\/pre>\nI have changed that to include the other schemes and that fixed the problem.<\/p>\n
\r\nelse if (url.startsWith(WebView.SCHEME_TEL) || \r\n url.startsWith(\"sms:\") ||\r\n url.startsWith(WebView.SCHEME_MAILTO) ||\r\n url.startsWith(WebView.SCHEME_GEO) ||\r\n url.startsWith(\"maps:\"))\r\n{\r\n try {\r\n Log.d(LOG_TAG, \"loading in external app\");\r\n Intent intent = new Intent(Intent.ACTION_VIEW);\r\n intent.setData(Uri.parse(url));\r\n cordova.getActivity().startActivity(intent);\r\n } catch (android.content.ActivityNotFoundException e) {\r\n LOG.e(LOG_TAG, \"Error opening external app \" + url + \": \" + e.toString());\r\n }\r\n}<\/pre>\nWith this in place, the web page error no longer shows up for any URL scheme. <\/p>\n
I’m not sure if this is the best solution, but it is the only one that I managed to implement.<\/p>\n","protected":false},"excerpt":{"rendered":"
