什麼是應用程序錯誤：6的Android許可

Question

這裏是我的代碼：

一段時間，我得到應用程序錯誤:3或:6有的時候我得到應用不許可的對話框。

public class MainActivity extends Activity { 
    private static final String BASE64_PUBLIC_KEY = "my public key"; 

    // Generate your own 20 random bytes, and put them here. 
    private static final byte[] SALT = new byte[] { 
     -43, 12, 76, -124, -101, -57, 74, -64, 51, 88, -95, -45, 77, -117, -36, -113, -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 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);

     }); 

     mHandler = new Handler(); 

     // Try to use more data here. ANDROID_ID is a single point of attack. 
     String deviceId = Secure.getString(getContentResolver(), Secure.ANDROID_ID); 

     // 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)),

      // 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

Answer 1

錯誤代碼6表示您錯過了檢查應用程序清單許可的權限。

<uses-permission android:name="com.android.vending.CHECK_LICENSE" /> 

錯誤代碼3意味着該應用程序是不是在谷歌的市場所以他們的許可證服務器不能確定他們是否應該有一個牌照或沒有。
