getApplication() vs. getApplicationContext()
...istered in the Manifest, you should never call getApplicationContext() and cast it to your application, because it may not be the application instance (which you obviously experienced with the test framework).
Why does getApplicationContext() exist in the first place ?
getApplication() is only ava...
How do I check if a string contains another string in Swift?
... other two involve explicitly using an NSString and the final one involves casting the String to an NSString
By bridging, you'd get:
var string = "hello Swift"
if string.bridgeToObjectiveC().containsString("Swift") {

Android Fatal signal 11 (SIGSEGV) at 0x636f7d89 (code=1). How can it be tracked down?
...the other posts on tracking down the reasons for getting a SIGSEGV in an Android app. I plan to scour my app for possible NullPointers related to Canvas use, but my SIGSEGV barfs up a different memory address each time. Plus I've seen code=1 and code=2 . If the memory address was 0x00000000 ...
Best way to trim strings after data entry. Should I create a custom model binder?
...r.PropertyType == typeof(string) && !propertyDescriptor.Attributes.Cast<object>().Any(a => a.GetType() == typeof(NoTrimAttribute)))

What is the difference between Collections.emptyList() and Collections.EMPTY_LIST

return (List<T>) EMPTY_LIST;
}

How to remove the querystring and get only the url?
... strrpos() in 'www.mydomain.com/myurl.html' will return 0 (FALSE casted to boolean to be more correct) so your substr will be empty. Use one: substr() OR parse_url() because using both makes no sense ;)

What's the difference between dynamic (C# 4) and var?
...can infer types that might not be desired because of subtypes and implicit casts. That is, var may have resolved a type statically different than expected when implicit casts occur (most notably to a more general type, but it's not limited to this). A trivial example is object x = "" vs. var x = "" ...
