У меня есть приложение для Android, которое использует службу лицензирования Google, и я получаю регулярные электронные письма от примерно 5% новых пользователей, жалующихся на неудачную проверку лицензии.Это начинает влиять на мои продажи.Какого черта я делаю не так?

// Construct the LicenseChecker with a Policy.
this.licenseChecker = new LicenseChecker(
this, new ServerManagedPolicy(this,
new AESObfuscator(SALT, getPackageName(), deviceId)),
BASE64_PUBLIC_KEY // Your public licensing key.
);
this.checkLicense();

this.licenseChecker.checkAccess(this.licenseCheckerCallback);

// 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

// 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.
