# Sencha Touch AMF
|
||
|
|
|
||
|
|
Sencha Touch AMF is an implementation of the [Action Message Format](http://en.wikipedia.org/wiki/Action_Message_Format) (AMF and AMFX) protocols for use with the Sencha Touch Ext.direct class. AMF
|
||
|
|
is a compact binary format used by Adobe Flash/Flex to serialize ActionScript
|
||
|
|
object graphs. AMF is typically used to encode messages that are sent between
|
||
|
|
an Adobe Flash client and a remote service. AMF is only a serialization
|
||
|
|
technology, not a transport, so AMF encoded binary data can be used with any
|
||
|
|
transport such as HTTP or HTTPS.
|
||
|
|
|
||
|
|
You can use the AmfRemotingProvider to make remote method invocation (RMI) calls
|
||
|
|
to a server, or as a way to provide APIs for a Direct Store to connect a data
|
||
|
|
source to a ListView or DataView.
|
||
|
|
|
||
|
|
For more information, please see the documentation for `Ext.direct.AmfRemotingProvider`.
|
||
|
|
|
||
|
|
**Note:** Sencha AMF is only distributed as part of [Sencha Touch Bundle](http://www.sencha.com/products/touch-bundle/) and [Sencha Complete](http://www.sencha.com/products/complete).
|
||
|
|
|
||
|
|
## Requiring AMF
|
||
|
|
|
||
|
|
The AMF class is not part of the core Sencha Touch framework, rather it is distributed as a package. As such, AMF is not immediately available for use within your Touch application and needs to be added as a required package.
|
||
|
|
|
||
|
|
Requiring the AMF package is a simple 3-step procedure
|
||
|
|
|
||
|
|
1. Edit your application's **app.json** file and add the `sencha-amf` package to the requires section:
|
||
|
|
|
||
|
|
<code>
|
||
|
|
requires: [ 'sencha-amf' ]
|
||
|
|
</code>
|
||
|
|
|
||
|
|
2. If not already present, add the following property to the file **.sencha/app/sencha.cfg**:
|
||
|
|
|
||
|
|
<code>
|
||
|
|
framework.packages.dir=${framework.dir}/packages
|
||
|
|
</code>
|
||
|
|
|
||
|
|
3. Refresh your application:
|
||
|
|
|
||
|
|
sencha app refresh
|
||
|
|
|
||
|
|
The AMF classes are now available for use within your application.
