Question

我正在我的应用程序中实现licensing，但没有找到响应代码的正式列表。

返回代码（int policyReason）的脚本是这样的：

private class MyLicenseCheckerCallback implements LicenseCheckerCallback {
    public void allow(int policyReason) {
        if (isFinishing()) {
            // Don't update UI if Activity is finishing.
            return;
        }
        // Should allow user access.
        displayResult(getString(R.string.allow));
    }

    public void dontAllow(int policyReason) {
        if (isFinishing()) {
            // Don't update UI if Activity is finishing.
            return;
        }
        displayResult(getString(R.string.dont_allow));
        // Should not allow access. In most cases, the app should assume
        // the user has access unless it encounters this. If it does,
        // the app should inform the user of their unlicensed ways
        // and then either shut down the app or limit the user to a
        // restricted set of features.
        // In this example, we show a dialog that takes the user to a deep
        // link returned by the license checker.
        // If the reason for the lack of license is that the service is
        // unavailable or there is another problem, we display a
        // retry button on the dialog and a different message.
        displayDialog(policyReason == Policy.RETRY);
    }

    public void applicationError(int errorCode) {
        if (isFinishing()) {
            // Don't update UI if Activity is finishing.
            return;
        }
        // This is a polite way of saying the developer made a mistake
        // while setting up or calling the license checker library.
        // Please examine the error code and fix the error.
        String result = String.format(getString(R.string.application_error), errorCode);
        displayResult(result);
    }
}

我发现了这些here（非官方的链接提供了指向没有int代码的正式文档的指向）：

Response Code                 Value
Licensed                      256
Not_licensed                  561
Error_Server_Failure          291
Error_Contacting_Server       291
Error_Not_Market_Managed      3
Error_Invalid_Package_Name    1
Error_Non_Matching_UID        2

以及以下here（非官方，未链接到带有int代码的官方文档）：

LICENSED                   = Hex: 0x0100, Decimal: 256
NOT_LICENSED               = Hex: 0x0231, Decimal: 561
RETRY                      = Hex: 0x0123, Decimal: 291
LICENSED_OLD_KEY           = Hex: 0x2,    Decimal: 2
ERROR_NOT_MARKET_MANAGED   = Hex: 0x3,    Decimal: 3
ERROR_SERVER_FAILURE       = Hex: 0x4,    Decimal: 4
ERROR_OVER_QUOTA           = Hex: 0x5,    Decimal: 5
ERROR_CONTACTING_SERVER    = Hex: 0x101,  Decimal: 257
ERROR_INVALID_PACKAGE_NAME = Hex: 0x102,  Decimal: 258 
ERROR_NON_MATCHING_UID     = Hex: 0x103,  Decimal: 259

但是在LicenseValidator类的官方文档中有以下内容：

// Server response codes.
private static final int LICENSED = 0x0;
private static final int NOT_LICENSED = 0x1;
private static final int LICENSED_OLD_KEY = 0x2;
private static final int ERROR_NOT_MARKET_MANAGED = 0x3;
private static final int ERROR_SERVER_FAILURE = 0x4;
private static final int ERROR_OVER_QUOTA = 0x5;

private static final int ERROR_CONTACTING_SERVER = 0x101;
private static final int ERROR_INVALID_PACKAGE_NAME = 0x102;
private static final int ERROR_NON_MATCHING_UID = 0x103;

（编辑）例如，policyReason可能返回291和256，但它们不在LicenseValidator中（0x101 = 257 ，0x102 = 258 , 0x103 = 259`）。

在哪里可以找到官方文档，其中包含要依赖的int响应代码列表？

我已经在lvl-library模块中进行了搜索，但没有成功。

（edit2）感谢@Mir Milad Hosseiny的回答，现在我确切地知道在哪里可以找到这些int代码。但是现在我有一个疑问：为什么允许应该返回RETRY或NOT_LICENSED并不允许RETRY和LICENSED？由于它们的名称，它们应该只返回LICENSED和NOT_LICENSED / RETRY。当用户确实从Google Play下载我的应用程序时，我必须知道如何正确处理该情况。 I asked a dedicated question about that here 。

非常感谢！

看看Android开发者网站上的Licensing Reference官方页面。

更新

LicenseCheckerCallback类上有3种回调方法。

1。公共无效允许（原因不明）

@param原因通常为Policy.LICENSED或Policy.RETRY。（尽管从理论上讲该策略也可以在此处返回Policy.NOT_LICENSED）

2。公共无效dontAllow（原因）

@param原因Policy.NOT_LICENSED或Policy.RETRY。（尽管从理论上讲，该策略也可以在此处返回Policy.LICENSED，例如，对LVL的调用花费了太长时间）

3。公共无效applicationError（int errorCode）

应用程序代码错误。呼叫者未正确呼叫或设置许可证检查器。应该被认为是致命的。

对于第一种和第二种方法，输入值reason是{{3}上可用的Policy.LICENSED，Policy.NOT_LICENSED和Policy.RETRY值之一}类源代码如下：

/**
 * LICENSED means that the server returned back a valid license response
 */
public static final int LICENSED = 0x0100;
/**
 * NOT_LICENSED means that the server returned back a valid license response
 * that indicated that the user definitively is not licensed
 */
public static final int NOT_LICENSED = 0x0231;
/**
 * RETRY means that the license response was unable to be determined ---
 * perhaps as a result of faulty networking
 */
public static final int RETRY = 0x0123;

对于第三种方法，LicenseCheckerCallback类源代码上的错误代码如下：

/** Application error codes. */
public static final int ERROR_INVALID_PACKAGE_NAME = 1;
public static final int ERROR_NON_MATCHING_UID = 2;
public static final int ERROR_NOT_MARKET_MANAGED = 3;
public static final int ERROR_CHECK_IN_PROGRESS = 4;
public static final int ERROR_INVALID_PUBLIC_KEY = 5;
public static final int ERROR_MISSING_PERMISSION = 6;

此外，您可以检查Policy和LicenseValidator类的源代码，以检查传递给这3个方法的输入值是否与它们的文档一致。
