Android :: Use WebView To Evaluate Java Script String And Return Value
Dec 1, 2009
Given that scripting is not natively supported in Android and wrapping libraries like javax.script.ScriptEngine into your app will make it too large, is it possible to send a javascript string to an invisible WebView and have it evaluate the string and return you the results (another string)? I want to go this route because I want to save all my scripts to disk so my app can remain small. edit I need Java code to evaluate javascript strings not the other way around. addJavascriptInterface() doesn't help.

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I have a strange issue. I am using KSOAP2 to create a soap request to a .net webservice. I do this in a few other places and everything works fine. The webservice basically queries a data base and takes the values from the data reader and creates a string. This string is then returned. When I run the webservice on my local machine(Without using android) it works fine. When I run it from the webserver (still not android) it works fine. When I call it from my phone however the line: String hazards = (String)envelope.getResponse().toString () ; //Get response from .net Web service Simply is filled with anyType{}. Now if I go to the webservice and I manually type in the contents from the database to represent what the string concatenation should be it works perfectly. The line: String hazards = (String)envelope.getResponse().toString(); //Get response from .net Web service Now returns the string value i need. Does anyone have any idea why this is happening or know a better place to ask this question?

Programming in Android, most of the text values are expected in CharSequence.
Why is that ? What is the benefit and what are the main impacts of using CharSequence over String ?
What are the main differences, and what issues are expected, while using them, and converting from one to another ?

I am looking for some examples of using xpath in Android? I have a string that contains a standard xml file. I believe I need to convert that into an xml document.
I have found this code which I think will do the trick:
CODE:............
Next steps
Assuming the code above is OK, I need to apply xpath to get values from cat: "/animal/mammal/feline/cat"
I look at the dev doc here: http://developer.android.com/reference/javax/xml/xpath/XPath.html and also look online, but I am not sure where to start!
I have tried to use the following code:
CODE:......
Evaluate the expression against the XML Document to get the result.
But I get "Cannot be resolved". Eclipse doesn't seem to be able to fix this import. I tried manually entering: javax.xml.xpath.XPath
But this did not work. Does anyone know any good source code that I can utilise, for Android platform? 1.5

I've been looking the source code available from the Restlet official tutorial.
I am trying to hit the Restlet server using the Android app from he tutorial adn I only get the JSON response, not the Java Object. I tried using all libraries and extensions, nothing works. When I hit the tutorial url though (http://restlet-example-serialization.appspot.com/contacts/123) I get the desired response. Any ideas? BTW, I am just using the server (GAE) in the example, not the GWT frontend.

Does anybody know of a work around for the android xml file string array inability to process string <item>'s that are not legal java variable names If not, is this not a major bug? Why does an item in an array need to generate a reference id anyway? Isn't this redundant?

So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:
CODE:.......
I hide my application name and my package for obvious reasons but I was wondering if anyone has ever encountered problems like this. Class is in the correct package, which is a library I have added. Other classes that I reference before are there and those can be made. Are there any other reasons a ClassNotFound Exception is thrown?
