Android Lib for LevelDB

This project wraps the LevelDB codebase in an Android NDK project which can be used as a library in Android projects.

Updates to the levelDB upstream are pulled in from time to time. To pull them in yourself add the google code project to your upstream
$ git remote add upstream https://code.google.com/p/leveldb
$ git pull upstream android

====Setup====
Create new Android project
 select from source

Create the C++ facet
 http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/

Clean

Run

Open the View for LogCat, and add a filter for AndroidLevelDB to see the sample LevelDB debug output, add a filter for DBbenchmark if you want to see the benchmark output.




====LevelDB Readme====

Android NDK port for LevelDB.

This git branch contains a make system to build LevelDB
against the Android NDK: http://developer.android.com/sdk/ndk/index.html

To build:
- Download install the Android NDK
- cd into this directory
- $ ndk-build

leveldb: A key-value store
Authors: Sanjay Ghemawat ([email protected]) and Jeff Dean ([email protected])

The code under this directory implements a system for maintaining a
persistent key/value store.

See doc/index.html for more explanation.
See doc/impl.html for a brief overview of the implementation.

The public interface is in include/*.h.  Callers should not include or
rely on the details of any other header files in this package.  Those
internal APIs may be changed without warning.

Guide to header files:

include/db.h
    Main interface to the DB: Start here

include/options.h
    Control over the behavior of an entire database, and also
    control over the behavior of individual reads and writes.

include/comparator.h
    Abstraction for user-specified comparison function.  If you want
    just bytewise comparison of keys, you can use the default comparator,
    but clients can write their own comparator implementations if they
    want custom ordering (e.g. to handle different character
    encodings, etc.)

include/iterator.h
    Interface for iterating over data. You can get an iterator
    from a DB object.

include/write_batch.h
    Interface for atomically applying multiple updates to a database.

include/slice.h
    A simple module for maintaining a pointer and a length into some
    other byte array.

include/status.h
    Status is returned from many of the public interfaces and is used
    to report success and various kinds of errors.

include/env.h
    Abstraction of the OS environment.  A posix implementation of
    this interface is in util/env_posix.cc

include/table.h
include/table_builder.h
    Lower-level modules that most clients probably won't use directly
