I want to study the Android API on my phone during my frequent and long metro rides (where I cannot connect to the internet). What would be the best way to make the documentation available (I would appreciate being able to use a search option and an index) ? Is copying all the documentation files from my PC to my Android device the best thing to do ? Is there any serious app that could provide this features ?

It seems like you could do this with something like storing web-pages for offline reading, unless you're trying to get the documentation in some specific non-HTML format. – eldarerathis Apr 22 '12 at 0:50
Good idea, thanks. – wil May 20 '12 at 15:10

You can download the documentation of Ice Cream Sandwich (Android 4.0) by the SDK Manager.

SDK manager-->Android 4.0.3 (API15)-->Documentation for Android SDK

It will download all the documentation in <android-sdk>\docs of your PC.

I guess it's the best thing to do. I hope I can use the search function using this method. – wil May 20 '12 at 15:09
You can search for files, even with the integrated google search, if you install Solid Explorer a new nice File explorer app for android (no I don't work there/know them etc) From the description: Indexed search, also available from the system (that means that you can search for files from the Google Search widget/app) – Mattias Isegran Bergander May 20 '12 at 18:55
Yes, you can use the search and it works same as the time you are online. – mammadalius May 20 '12 at 19:57

There is an app that does provide that:

Thank you for the hint. Actually I already use this app but it is more a tutorial than a reference, there is no search function etc.. – wil May 20 '12 at 15:07

It's not the solution you are looking for exactly but an alternative way would be to use the code completion feature of the AIDE app, an Android IDE running on Android.

Plus you can code during your metro rides and even meetings :)

Ah yeah, AIDE is a very nice app too, +1 for your idea ! – wil May 21 '12 at 0:25

You can find a pdf version for most sections that are built monthly with details of what has changed in the previous month. The website has been split into sections for each book.

The sections are all available as a preview and as a download for free.
