我正在尝试使用示例应用在Android中配置Google许可服务LVL
按照HERE
的说明进行操作我刚刚尝试使用附带的代码配置基本应用
public class MainActivity extends Activity {
private static final String BASE64_PUBLIC_KEY = "mykeywithoutspaces";
// Generate your own 20 random bytes, and put them here.
private static final byte[] SALT = new byte[] {
-00, 65, 30, -128, -58, -57, 00, -64, 51, 32, -95, -45, 77, -117, -36, -15, -11, 32, -64,
89
};
private TextView mStatusText;
private Button mCheckLicenseButton;
private LicenseCheckerCallback mLicenseCheckerCallback;
private LicenseChecker mChecker;
// A handler on the UI thread.
private Handler mHandler;
@Override

// Try to use more data here. ANDROID_ID is a single point of attack.

// Library calls this when it's done.
mLicenseCheckerCallback = new MyLicenseCheckerCallback();
// Construct the LicenseChecker with a policy.
mChecker = new LicenseChecker(
this, new ServerManagedPolicy(this,
new AESObfuscator(SALT, getPackageName(), deviceId)),
BASE64_PUBLIC_KEY);
doCheck();
}
protected Dialog onCreateDialog(int id) {

}

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 Market.
// 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;
}
String result = String.format(getString(R.string.application_error), errorCode);
displayResult(result);
}
}
@Override
protected void onDestroy() {
super.onDestroy();
mChecker.onDestroy();
}
}
但不幸的是，应用程序因错误

有什么问题？
在第
行private static final String BASE64_PUBLIC_KEY = "mykeywithoutspaces";
我设置了真正的公钥
答案 0 :(得分：5)
当我在Google帐户上编辑了一些个人资料信息时，Key On Google Developers控制台发生了变化。
我已经更新了密钥，现在一切正常。
