Properties

Mandatory Properties

The following properties must be set for all builds.

sdk.dir

The location of the Android SDK on the local machine.

target

The version of the Android platform to target. This must be set to an identifier such as android-18 and should typically match the android:targetSdkVersion set in AndroidManifest.xml.

Signing Properties (Mandatory for Release Builds)

In order to use the package-release macro, it is necessary to set the following properties (probably in your local properties file rather than directly in build.xml.

key.store

The location of a Java key store containing the key used to sign Android apps.

key.alias

The key store alias to use when signing Android apps.

Other Properties

For all other properties, the defaults should suffice unless you are doing something complex, such as building multiple versions of the same app from a single project.

Local Properties File

Before assigning default values to any unassigned properties, the Antlib will check for the existence of the local.properties file in the project root. This provides a useful way to set property values that may differ between users (e.g. the install location of the Android SDK).
