Class ServerManagedPolicy

java.lang.Object

com.google.android.vending.licensing.ServerManagedPolicy

All Implemented Interfaces:

Policy

public class ServerManagedPolicy
extends Object
implements Policy

Default policy. All policy decisions are based off of response data received from the licensing service. Specifically, the licensing server sends the following information: response validity period, error retry period, and error retry count.

These values will vary based on the the way the application is configured in the Android Market publishing console, such as whether the application is marked as free or is within its refund period, as well as how often an application is checking with the licensing service.

Developers who need more fine grained control over their application's licensing policy should implement a custom Policy.

Constructor Detail

ServerManagedPolicy

public ServerManagedPolicy(android.content.Context context,
                   Obfuscator obfuscator)

Parameters:

context - The context for the current application

obfuscator - An obfuscator to be used with preferences.

Method Detail

processServerResponse

public void processServerResponse(int response,
                         ResponseData rawData)

Process a new response from the license server.

This data will be used for computing future policy decisions. The following parameters are processed:

• VT: the timestamp that the client should consider the response valid until
• GT: the timestamp that the client should ignore retry errors until
• GR: the number of retry errors that the client should ignore

Specified by:

processServerResponse in interface Policy

Parameters:

response - the result from validating the server response

rawData - the raw server response data

getRetryCount

public long getRetryCount()

getValidityTimestamp

public long getValidityTimestamp()

getRetryUntil

public long getRetryUntil()

getMaxRetries

public long getMaxRetries()

allowAccess

public boolean allowAccess()

Check if the user should be allowed access to the application. This implementation allows access if either:

1. a LICENSED response was received within the validity period
2. a RETRY response was received in the last minute, and we are under the RETRY count or in the RETRY period.

Specified by:

allowAccess in interface Policy
