Android许可样本返回代码3.这是什么意思？

Question

我尝试过许可样品。它说“应用程序错误= 3”。 我在developer.android.com找到了许可响应代码表，但是数字3如何与上面的列表相对应？那段代码意味着什么？

Answer 1

查看源代码com.android.vending.licensing.LicenseValidator：

/**
 * Contains data related to a licensing request and methods to verify
 * and process the response.
 */
class LicenseValidator {
  private static final String TAG = "LicenseValidator";

  // 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;

  ... ...

“应用程序错误= 3”表示ERROR_NOT_MARKET_MANAGED，请查看答案here以了解如何处理它。
