=Basic instructions=

1. Copy config.sample.py to config.py and edit the path within accordingly
   to point to the Android tools
2. Make a repo directory and put APK files in it
3. Run update.py
4. If it reports that any metadata files are missing, you can create them
   in the metadata directory and run it again.
5. To ease creation of metadata files, run update.py with the -c option. It
   will create 'skeleton' metadata files that are missing, and you can then
   just edit them and fill in the details.
6. Then, if you've changed things, run update.py again.
7. Running update.py adds an Icons directory into the repo directory, and
   also creates the repository index (index.xml).
8. Transfer the repo directory to the appropriate http server. The script
   in upload.sh is an example of how to do this.

=Build System Requirements=

To be able to auto-build packages, you're going to need:

*Linux
*Python
*A fully functional Android SDK with all SDK platforms and tools
*The Android NDK
*Ant
*Ant Contrib Tasks (Debian package ant-contrib)
*JavaCC (Debian package javacc)
*VCS clients: svn, git, hg, bzr
*A keystore for holding release keys. (Safe, secure and well backed up!)

You then need to create a config.py (copy config.sample.py and follow the
instructions) to specify the locations of some of these things.
Also make sure the SDK tools - found in $SDK/tools/ - are in your $PATH.

=MetaData=

Information used by update.py to compile the public index comes from two
sources, 1) the APK files in the repo directory, and 2) the metadata files
in the metadata directory.

The metadata files are simple, easy to edit text files, always named as the
application's package ID with '.txt' appended. Within the file, the following
fields are recognised:

==License==

The license for the application.

Common values: GPLv2, GPLv2+, GPLv3, Apache2, MIT, BSD

==Name==

The name of the application. Normally, this field should not be present since the
application's correct name is retrieved from the APK file. However, in a situation
where an APK contains a bad or missing application name, it can be overridden
using this.

==Web Site==

The URL for the application's web site.

==Source Code==

The URL to view or obtain the application's source code. This should be
something human-friendly. Machine-readable source-code is covered in the
'Repo' field.

==Issue Tracker==

The URL for the application's issue tracker. Optional, since not all
applications have one.

==Donate==

The URL to donate to the project. This could be the project's donate page
if it has one, or perhaps even a direct PayPal link.

==Summary==

A brief summary of what the application is.

==Description==

A full description of the application. This can span multiple lines, and is
terminated by a line containing a single '.'.

==Repo Type==

The type of repository - for automatic building from source. If this is not
specified, automatic building is disabled for this application. Possible
values are:

  git, svn, hg, bzr

==Repo==

The repository location. Usually a git: or svn: URL.

Normally the repository is checked out once for the application, then moved
to a particular revision/commit/tag for each build version. For an SVN
repository though, this behaviour can be changed by appending a * to the
repository URL - in this case the repository is checked out once per build
version, with the subdir parameter in place of the *. This can be beneficial
when dealing with very large SVN repositories.

For a Subversion repo that requires authentication, you can precede the repo
URL with username:password@ and those parameters will be passed as --username
and --password to the SVN checkout command.

==Build Version==

Any number of these fields can be present, each specifying a version to
automatically build from source. The value is a comma-separated list.
For example:

    Build Version:0.12,3,651696a49be2cd7db5ce6a2fa8185e31f9a20035

The above specifies to build version 0.12, which has a version code of 3.
The third parameter specifies the tag, commit or revision number from
which to build it in the source repository.

In addition to the three, always required, parameters described above,
further parameters can be added (in name=value format) to apply further
configuration to the build. These are:

 subdir=<path>   - Specifies to build from a subdirectory of the checked out
                   source code. Normally this directory is changed to before
                   building, but there is a special case for SVN repositories
                   where the URL is specified with a * at the end. See the
                   documentation for the Repo field for more information.
 bindir=<path>   - Normally the build output (apk) is expected to be in the
                   bin subdirectory below the ant build files. If the project
                   is configured to put it elsewhere, that can be specified
                   here, relative to the base of the checked out repo..
 oldsdkloc=yes   - The sdk location in the repo is in an old format, or the
                   build.xml is expecting such. The 'new' format is sdk.dir
                   while the VERY OLD format is sdk-location. Typically, if
                   you get a message along the lines of:
                      "com.android.ant.SetupTask cannot be found"
                   when trying to build, then try enabling this option.
 target=<target> - Specifies a particular SDK target, when the source doesn't.
                   This is likely to cause the whole build.xml to be rewritten,
                   which is fine if it's a 'standard' android file or doesn't
                   already exist, but not a good idea if it's heavily
                   customised.
 rm=<relpath>    - Specifies the relative path of file to delete before the
                   build is done. The path is relative to the base of the
                   build directory - i.e. the directory that contains
                   AndroidManifest.xml.
 antcommand=xxx  - Specify an alternate ant command (target) instead of the
                   default 'release'.
 insertversion=x - If specified, the pattern 'x' in the AndroidManifest.xml is
                   replaced with the version number for the build.
 insertvercode=x - If specified, the pattern 'x' in the AndroidManifest.xml is
                   replaced with the version code for the build.
 update=no	   By default, 'android update project' is used to generate or
                   update the build.xml file. Specifying update=no bypasses
                   that.
 initfun=yes	   Enables a selection of mad hacks to make com.funambol.android
                   build. Probably not useful for any other application.
 buildjni=yes      Enables building of native code via the ndk-build script before
                   doing the main ant build.
 submodules=yes    Use if the project (git only) has submodules - causes git
                   submodule init and update to be executed after the source is
                   cloned.
 encoding=xxxx     Adds a java.encoding property to local.properties with the given
                   value. Generally the value will be 'utf-8'. This is picked up by
                   the SDK's ant rules, and forces the Java compiler to interpret
                   source files with this encoding. If you receive warnings during
                   the compile about character encodings, you probably need this.

 prebuild=xxxx     Specifies a shell command (or commands - chain with &&) to
                   run before the build takes place. Backslash can be used
                   as an escape character to insert literal commas, or as the
                   last character on a line to join that line with the next.
                   They have no special meaning in other contexts; in
                   particular, literal backslashes should not be escaped.

 novcheck=yes      Don't check that the version name and code in the resulting apk
                   are correct by looking at the build output - assume the metadata
                   is correct. This takes away a useful level of sanity checking, and
                   should only be used if the values can't be extracted.
 fixtrans=yes      Modifies any instances of string resources that use multiple
                   formatting arguments, but don't use positional notation. For
                   example, "Hello %s, %d" becomes "Hello %1$s, %2$d". Newer versions
                   of the Android platform tools enforce this sensible standard. If you
                   get error messages relating to that, you need to enable this.

Another example, using extra parameters:

    Build Version:1.09.03,10903,45,subdir=Timeriffic,oldsdkloc=yes

==Use Built==

Set this to "Yes" to use built versions of the application for the repository.
Currently, this just triggers update.py to copy the relevant apks and tarballs
from the 'built' directory before updating the repo index.

==AntiFeatures==

This is optional - if present, it contains a comma-separated list of any of
the following values, describing an AntiFeature the application has:

  "Ads" - the application contains advertising
  "Tracking" - the application tracks and reports your activity to somewhere
  "NonFreeNet" - the application promotes a non-Free network service
  "NonFreeAdd" - the application promotes non-Free add-ons

==Disabled==

If this field is present, the application does not get put into the public
index. This allows metadata to be retained while an application is temporarily
disabled from being published. The value should be a description of why the
application is disabled.
