Using ant to implement bulk packaging Android applications

The main story is how to automatically build tools ant, batch packaging of applications to generate applications corresponding to different markets:

First take a look at the Java Engineering anttest for packaging and the Android architecture that needs to be packaged for release : market.txt to store the market markings that need to be packaged, such as: Youmeng Gfan .....   In this file, you add the channel name to your needs. Then look at the implementation of the bulk packaging Anttest class content:

Package com.cn.ant;

Import Java.io.BufferedWriter;
Import Java.io.File;
Import Java.io.FileReader;

Then there is the part of the Android project that needs to be modified:

1. Modify the SDK root directory in Local.properties:
Sdk.dir=d:androidandroid-sdk-windows-r17android-sdk-windows-r17
2. Modify the path and password of the signed file in Ant.properties (if required)
Key.store=d:androidmykeystore
key.store.password=123456
Key.alias=mykey
key.alias.password=123456
3. Modify AndroidManifest.xml.temp
Copy androidmanifest.xml, named AndroidManifest.xml.temp
Change the place you want to replace to a placeholder, consistent with the placeholder constant in the package engineering Anttest
such as: <meta-data android:value= "@market @ " android:name= "Umeng_channel"/>
4. In Build.xml:
<project name= "XXX" default= "help" >,xxx must be the Android project name.

If the machine does not have an ant environment variable configured, you can configure it according to the following steps:

Ant environment variable settings:

There are 2 main environment variables used by Windows ANT, Ant_home, PATH.

Set the ant_home to point to Ant's installation directory.

To set the method:
Ant_home = d:/apache_ant_1.7.0

Will%ant_home%/bin; %ant_home%/lib is added to the path of the environment variable.

Set Method:
PATH =%ant_home%/bin;%ant_home%/lib
