Bob:
You're probably right b/c I've been building for Android 1.1. In an effort
to make a decision about this feature, I did some searching for statistics
on installed API levels but couldn't find them.
On another note, is it possible to provide a conditional instruction for
formatting date/time based on the user's Android package:
if (package > 1.1) {
//cooler date time format
} else {
//regular date time format
}
Let me guess? It is technically possible, but not in Eclipse since Eclipse
won't even let it compile w/ a function that doesn't compile. Or can I
build it for Android 1.2 but allow users of 1.1 to download it by specifying
a different min-SDK level than it is built for? If so, can I write a
conditional instruction based on the device's SDK level?
Thanks,
Nick Owens

Subject: [android-developers] Re: FormatDateTime
I really doubt that Eclipse is wrong here. First, a couple quick-and-
basic steps.
If you hold the mouse over each variable, it will tell you the type.
Finally, if you click on the 'this' the code, and type control-T,
you'll get a pop-up with showing the class hierarchy. The second from
the type should read 'Context -- android.content'
Now, finally: On the left where it shows the Package Explorer, click
right on your project name (at the top level of the hierarchy). Choose
Properties, and then choose Android in the property pane that comes
up, to see the Android-related properties. It will give you a table of
Android target names.
My guess: You have selected Android 1.1 (API Level 2). The method in
question, according to the nice Javadoc, was introduced in API level
3. Then Eclipse should let you build your code.
Eclipse is telling you that the method isn't available in that version
of the SDK. It compiles against that specific version of android.jar,
based on that checkbox.
So what does it mean to select a different version? It means your code
will compile, but will only work on devices newer than Android 1.1. In
the androidManifest.xml file, there are flags indicating what the
minimum and intended SDK versions are. If you indicate it should work
on API 2, they'll be able to install it, but get a NoSuchMethodError
at runtime.
There are very few devices running Android 1.1, but you'll have to
decide what you want to do about that. Statistics are available.
