Question

我最近在我的应用程序中添加了Android的LVL复制保护，至少可以说结果不稳定。

我在开发人员控制台中手动设置的每个测试响应似乎都按预期工作。但是，当我设置“正常响应”时，就是故障开始的地方。星期三，我首次上传了这个应用程序，在它上市后不久，就按照预期报告了许可。

然而，昨天下午没有任何警告，我的应用程序突然告诉我，我没有注意到。到目前为止，我没有对开发人员的控制台或代码进行任何更改。在发现这个之后，我立即取消发布，直到找到解决方案。我已经尝试清除应用的缓存和Google Play的缓存。

所以，我不知道我在这里做错了什么。我通过APK在Eclipse手机上安装了我自己的应用程序，而不是从市场上购买我自己的应用程序。要对LVL进行实时测试，我是否必须实际购买自己的应用程序，或者上传到开发人员的页面是否足够？我的LVL代码实际上是示例页面的副本，我在版本中尝试在进一步优化它之前尝试工作。我在这里发布了一些可识别的信息。

public class Main extends Activity {
private static final byte[] SALT = { <salt> };
private static final String B64 = "<base 64 key>";
private dbHelper db = new dbHelper(this);
private int requestCode;

LicenseCheckerCallback mLCC;
    LicenseChecker mC;
Handler mH;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    checkL();
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == 1) {
        startActivity(new Intent(Main.this, MainProfiler.class)); //callback for profile setup
        finish();
    }
}

protected void checkL() {
    String a = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID); 
    mH = new Handler();
    mLCC = new settingsResolved();
    mC = new LicenseChecker(
            this, 
            new ServerManagedPolicy(this, new AESObfuscator(SALT, getPackageName(), a)),
            B64);
    mC.checkAccess(mLCC);
}

是。设置“正常响应”时，您的测试帐户需要通过Google Play购买该应用。对我来说，我只是为测试帐户设置了“LICENSED”的响应。我太便宜了，不能买我自己的应用程序; - ）

为什么Android的LVL会锁定我自己的应用程序？
