The Android Pay API has been superseded by the Google Pay API. Please see android-quickstart for an up-to-date sample.
This sample demonstrates basic usage of the Android Pay API. For more information, visit the following link:

Run the Android SDK Manager (android sdk) and ensure that you have the following installed:
In order to run this sample with the 'direct integration' model (as opposed to a processor gateway token) you will need to generate a public/private key pair and put the base64-encoded public key into the resources directory.
In order to generate a suitable key, execute the provided genkey.sh script. You should see
some output like this:
Private-Key: (256 bit)
priv:
7c:a5:b4:31:fa:ec:26:88:65:77:76:0d:c8:6f:ec:
e1:a8:01:1d:4c:ff:04:87:4d:05:ca:a2:a1:30:49:

pub:

ASN1 OID: prime256v1
...Taking the value of the the pub key and as $PUBLICKEY, run the following:
echo $PUBLICKEY | xxd -r -p | base64Put the result of that commmand into app/src/main/res/values/ids.xml:
<resources>
<string name="public_key">REPLACE_ME</string>
...
</resources>The genkey.sh script uses openssl to generate the key and generates a .pem file containing
the key for future reference. Consult the script for more details on how the openssl command is
invoked.
