Offline Wikipedia readers
Some of the many ways to read Wikipedia while offline:
Some of them are mobile applications -- see 'list of Wikipedia mobile applications'.
Where do I get it?English-language Wikipedia
Should I get multistream?
TLDR:GET THE MULTISTREAM VERSION! (and the corresponding index file, pages-articles-multistream-index.txt.bz2)
pages-articles.xml.bz2 and pages-articles-multistream.xml.bz2 both contain the same .xml file. So if you unpack either, you get the same file. But with multistream, it is possible to get an article from the archive without unpacking the whole thing. Your reader should handle this for you, if your reader doesn't support it it will work anyway since multistream and non-multistream contain the same .xml. The only downside to multistream is that it is marginally larger. You might be tempted to get the smaller non-multistream archive, but this will be useless if you don't unpack it. And it will unpack to ~5-10 times its original size. Penny wise, pound stupid. Get multistream.
How to use multistream?
For multistream, you can get an index file, pages-articles-multistream-index.txt.bz2. The first field of this index is the number of bytes to seek into the compressed archive pages-articles-multistream.xml.bz2, the second is the article ID, the third the article title.
Cut a small part out of the archive with dd using the byte offset as found in the index. You could then either bzip2 decompress it or use bzip2recover, and search the first file for the article ID.
Other languages
In the dumps.wikimedia.org Android rooting software download for pc. directory you will find the latest SQL and XML dumps for the projects, not just English. The sub-directories are named for the language code and the appropriate project. Some other directories (e.g. simple, nostalgia) exist, with the same structure. These dumps are also available from the Internet Archive.
Where are the uploaded files (image, audio, video, etc.)?
Images and other uploaded media are available from mirrors in addition to being served directly from Wikimedia servers. Bulk download is (as of September 2013) available from mirrors but not offered directly from Wikimedia servers. See the list of current mirrors. You should rsync from the mirror, then fill in the missing images from upload.wikimedia.org; when downloading from
upload.wikimedia.org you should throttle yourself to 1 cache miss per second (you can check headers on a response to see if was a hit or miss and then back off when you get a miss) and you shouldn't use more than one or two simultaneous HTTP connections. In any case, make sure you have an accurate user agent string with contact info (email address) so ops can contact you if there's an issue. You should be getting checksums from the mediawiki API and verifying them. The API Etiquette page contains some guidelines, although not all of them apply (for example, because upload.wikimedia.org isn't MediaWiki, there is no maxlag parameter).
Unlike most article text, images are not necessarily licensed under the GFDL & CC-BY-SA-3.0. They may be under one of many free licenses, in the public domain, believed to be fair use, or even copyright infringements (which should be deleted). In particular, use of fair use images outside the context of Wikipedia or similar works may be illegal. Images under most licenses require a credit, and possibly other attached copyright information. This information is included in image description pages, which are part of the text dumps available from dumps.wikimedia.org. In conclusion, download these images at your own risk (Legal)
Dealing with compressed files
Compressed dump files are significantly compressed, thus after being decompressed will take up large amounts of drive space. A large list of decompression programs are described in Comparison of file archivers. The following programs in particular can be used to decompress bzip2 .bz2.zip and .7z files.
Beginning with Windows XP, a basic decompression program enables decompression of zip files.[1][2] Among others, the following can be used to decompress bzip2 files.

Dealing with large files
As files grow in size, so does the likelihood they will exceed some limit of a computing device. Each operating system, file system, hard storage device, and software (application) has a maximum file size limit. Each one of these will likely have a different maximum, and the lowest limit of all of them will become the file size limit for a storage device.
The older the software in a computing device, the more likely it will have a 2 GB file limit somewhere in the system. This is due to older software using 32-bit integers for file indexing, which limits file sizes to 2^31 bytes (2 GB) (for signed integers), or 2^32 (4 GB) (for unsigned integers). Older Cprogramming libraries have this 2 or 4 GB limit, but the newer file libraries have been converted to 64-bit integers thus supporting file sizes up to 2^63 or 2^64 bytes (8 or 16 EB).
Before starting a download of a large file, check the storage device to ensure its file system can support files of such a large size, and check the amount of free space to ensure that it can hold the downloaded file.
File system limits
There are two limits for a file system: the file system size limit, and the file system limit. In general, since the file size limit is less than the file system limit, the larger file system limits are a moot point. A large percentage of users assume they can create files up to the size of their storage device, but are wrong in their assumption. For example, a 16 GB storage device formatted as FAT32 file system has a file limit of 4 GB for any single file. The following is a list of the most common file systems, and see Comparison of file systems for additional detailed information.
Operating system limits
Each operating system has internal file system limits for file size and drive size, which is independent of the file system or physical media. If the operating system has any limits lower than the file system or physical media, then the OS limits will be the real limit.
Google Android is based on Linux, which determines its base limits.
TipsDetect corrupted files
It is useful to check the MD5 sums (provided in a file in the download directory) to make sure the download was complete and accurate. This can be checked by running the 'md5sum' command on the files downloaded. Given their sizes, this may take some time to calculate. Due to the technical details of how files are stored, file sizes may be reported differently on different filesystems, and so are not necessarily reliable. Also, corruption may have occurred during the download, though this is unlikely.
Reformatting external USB drives
If you plan to download Wikipedia Dump files to one computer and use an external USB flash drive or hard drive to copy them to other computers, then you will run into the 4 GB FAT32 file size limit. To work around this limit, reformat the >4 GB USB drive to a file system that supports larger file sizes. If working exclusively with Windows XP-Vista-7 computers, then reformat the USB drive to NTFS file system.
Linux and Unix
If you seem to be hitting the 2 GB limit, try using wget version 1.10 or greater, cURL version 7.11.1-1 or greater, or a recent version of lynx (using -dump). Also, you can resume downloads (for example wget -c).
Why not just retrieve data from wikipedia.org at runtime?
Suppose you are building a piece of software that at certain points displays information that came from Wikipedia. If you want your program to display the information in a different way than can be seen in the live version, you'll probably need the wikicode that is used to enter it, instead of the finished HTML.
Also, if you want to get all the data, you'll probably want to transfer it in the most efficient way that's possible. The wikipedia.org servers need to do quite a bit of work to convert the wikicode into HTML. That's time consuming both for you and for the wikipedia.org servers, so simply spidering all pages is not the way to go.
To access any article in XML, one at a time, access Special:Export/Title of the article.

One e-book reader worthy of consideration for your Android tablet is the Amazon Kindle app. As the name implies, it provides access to the Kindle eLibrary of books right there on your Android tablet — the same library you’d have if you owned a Kindle e-book reader, but you were smarter than that.
You can pick up a copy of the Amazon Kindle app free at the Google Play Store.
Download Android Os For Tablets
When you start the Amazon Kindle app for the first time, you may be asked to register or sign in to your Amazon account. Do so. By signing in, you can instantly coordinate your Kindle e-book library with any previous purchases you may have made.
Download Wikipedia For Android Tablet Download
After everything is set up, you can enjoy reading Kindle e-books just as you would any other e-book reader on an Android tablet; they all work basically the same, although some interesting features are available on the Amazon Kindle app that aren’t available on other e-books readers, such as Play Books. For example, you can highlight text and perform web searches in a Kindle e-book. That’s pretty swanky.
