So, anyway, are there any libraries like that?

This reply is kind of late and I'm only just learning Android so I might be off here.

I think what you want is Index Scrolling as shown on the Android Developers site? Except you don't want alphabetical sections, you want section names. But actually that's just a less specific example of the same thing (note how the Contacts app has "Me" at the top.

As far as I can work out you need to set fastScrollEnabled to true on your ListView and then implement SectionIndexer .

Last, we’ve updated the Android Support Library (r18) with several key APIs to help you build great apps with broad compatibility. Most important, we've added an Action Bar API to let you build this essential Android design pattern into your app with compatibility back to Android 2.1.

So is there any reason to use ABS anymore? I have an app I want to overhaul and I'm curious if I should bother with ABS or if this should nail what I need.

Tunga posted:

A couple of Android developer advocates were asked about this on G+ or something, I saw it recently. Their answer was that if you're already using ABS then there's no great requirement to recode your app, but for new apps you should probably use Google's version since you know it'll keep working in the future.

Sereri posted:

But isn't it just dropping the ABS, including the library and removing all the Sherlock prefixes?

I updated the SDK but Android Studio doesn't offer 4.3 as a targetable API level. Do I need to do something else before it'll show up? I'm new to all of this.

Tunga posted:

I wasn't, but now I am, and it doesn't seem to have made a difference.

I don't desperately need to target 4.3, it just seemed odd that I can't.

I'm having a lot of trouble getting a ListView working. I've tried using two different adapters (LazyAdapter and then a custom SimpleAdapter)

My app takes JSON data and then parses it into a listview (simple enough). But I'm also using the ImageLoader library from nostra13 ( https://github.com/nostra13/Android-Universal-Image-Loader ) to take a dynamically generated URL and download an image.

I'm getting NullPointerExceptions, and just now got this when using the custom SimpleAdapter:

code:

I'll attach the code that's giving me grief below:
https://gist.github.com/verkaufer/985a7f4e0f145a729e0b (Results.Java)
https://gist.github.com/verkaufer/28ae68336f8b698affec (MyAdapter.java - the new adapter that generated the above error)
https://gist.github.com/verkaufer/63d9764dc80c2fa09d10 (LazyAdapter.java - old adapter that I was using but pokeman on line 72 always remained null)

Should I keep using my LazyAdapter? I tried the other one because I was stumped on why pokeman wasn't populating (even using breakpoints, it stayed null the entire time).

Fluue posted:

Whoops! I must have deleted that line when refactoring..

I'm still receiving the same error though. I tried a solution provided on StackOverflow (changing my activity name for Results.java to .Results in AndroidManifest.xml) but that still results in the same error and app crash. Is there a specific debug method I should look at to determine where things are going wrong?

Ugh, spent a while trying to figure out why my app was crashing on a friend's phone.
Apparently I was using methods that required an API that was newer than the minimum, which obviously gave no (explicit) warning from Eclipse.

I assume you've updated to the latest SDK? Lint should catch things like that - which APIs were they? This is probably a bug that should be reported.

Angryhead posted:

My android:minSdkVersion was set to "8" (and that was what the device was using) and I was using the View.setScaleX method, which was added in API level 11. App crashes with an java.lang.NoSuchMethodError.

No warning from either Eclipse or Lint. Found somebody on Stackoverflow with the same problem... back in December of 2012. No solution.

Thought it does seem like I'm missing the latest version of the SDK so I'll try updating and maybe this'll keep this from happening.

Where is MenuItemCompat coming from? Is that a static call?

Can I reference an existing string in strings.xml when I define another string? For example:

XML code:

<string name="foo">Foo</string>
<string name="bar">@string/foo + Bar</string>

I want the "bar" string to return "fooBar" right now or "ShittyBar" later if I change the value of the "foo" string to "lovely".

Karthe posted:

Is there a good or common directory that apps can write files to? I'm planning on implementing a feature that will let users export vocabulary lists from my app. I want them to be able to easily find and copy them off the device afterwards.

Do any of you guys have any experience with the Play Store's third-party translation services? I translated the UI of my Japanese dictionary app into Japanese but want someone native to proof-read it. I'm feeling bad asking friends to proof my stuff for free, so I'm considering shelling out a bit of cash up front to get a bona fide translation in place before launch.

Any idea if there is a way for me to get my hands on a physical copy of the Android SDK documentation, short of just printing it out and putting it in a binder?

Tunga posted:

There should be a docs folder in your SDK root.

I'm trying to create an action bar which looks something like the one in the AOSP Contacts app. The main bar is blue, the icons and text are white, and the overflow menu is white with dark text.

In my case I'm using purple rather than blue but the principle should be the same.

The problem is that if I use Theme.Holo.Light as my base theme then the overflow icon turns dark grey which looks rubbish on a solid colour, it should be white. If I use Theme.Holo.Light.DarkActionBar then the icon is white (good) but the overflow menu will have a black background (bad).

Which of these things is it easier for me to manually override and how do I go about it? I'm struggling to find any decent API documentation for the Widget.Holo.blabla stuff so I don't even know what it is that I should be overriding.

Here's my code right now:

While we're at it, what is the difference between Solid and Solid.Inverse?
