cause anything to become abandoned.
> Cannot access specific non http or https URLs that are Whitelisted
> ------------------------------------------------------------------
>
> Key: CB-10897
> URL: https://issues.apache.org/jira/browse/CB-10897
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-plugin-whitelist
> Affects Versions: Master
> Environment: cordova-android 5.1.1
> Reporter: Karen Tran
> Labels: android, whitelist
> Fix For: Master
>
>
> In config.xml when I whitelist specific non http or https URLs such as
> {code}<allow-intent href="mailto:ktop...@gmail.com"; />{code}
> and in index.html I add a link with that specific URL,
> {code}<a href="mailto:ktop...@gmail.com";>mailto link</a>{code}
> I cannot access the link when I run the application. If I change the
> allow-intent to use a wildcard, *, I can get it to work.
> {code}<allow-intent href="mailto:*"; />{code}
> The expected behavior is that I should be able to specify an exact URL in the
> whitelist, but I am not able to. I investigated the Whitelist plugin and
> Whitelist.java in cordova-android and I found the issue.
> First I looked at the whitelist itself. URLs from config.xml are added to the
> whitelist correctly. No problems here.
> Next I looked at how the URL from index.html is being compared to the
> whitelist. I traced through with the Android Studio debugger and found this:
> At [Line
> 85|https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/Whitelist.java#L85]
> of Whitelist.java in cordova-android, there is actually a
> NullPointerException happening, but it didn't get printed out with the Log :(
> (this needs to be fixed). I made some modifications to Whitelist.java so that
> the stack trace gets printed out, along with with values of 'host'.

> Whitelist host is correct, so that got parsed correctly, but the Uri host is
> not correct, it is null. We try to call host.matcher(null).matches with a
> null object and therefore got the NPE.
> Working backwards from here, the issue stems from Android's Uri class parsing
> the URL. At [Line
> 158|https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/Whitelist.java#L158]
> of Whitelist.java, we call:
> {code}Uri parsedUri = Uri.parse(uri);{code}
> Using the debugger, once the uri gets parsed, you'll see that the value of
> 'host' is 'NOT_CACHED'. This is the part where I got lost in Android Uri
> class because it's hard to debug there.
> The conclusion that I came to is that Android's Uri class doesn't parse
> 'host' correctly, but does parse 'scheme' correctly. I also tested market:
> URL and that has the same behavior.
> Android's definition of 'host' is probably different from Cordova's
> definition of 'host' so we should try to use something other than the Uri
> class to parse the URL. Android's definition of 'host' is probably parsed to
> a ':'
> I can try to work on a solution to not use the Uri class to parse.
