android - Google Play License - what is error 6? -

i testing app google play license api. app binds licensing service, callback gives error 6. i've checked error codes in licensevalidator , not 1 of error codes listed there.

does know error 6 means?

public class myactivity extends fragmentactivity {      private static final string base64_public_key = "zzzz";      private static final byte[] salt = new byte[] {         xxxx     };      private licensecheckercallback mlicensecheckercallback;     private licensechecker mchecker;      @override     protected void oncreate(bundle savedinstancestate)     {     super.oncreate(savedinstancestate);          string deviceid = secure.getstring(getcontentresolver(), secure.android_id);          // library calls when it's done.         mlicensecheckercallback = new yahlicensecheckercallback();          // construct licensechecker policy, obfuscator , public key         mchecker = new licensechecker(this,                  new servermanagedpolicy(this,                 new aesobfuscator(salt, getpackagename(), deviceid)),                 base64_public_key);         mchecker.checkaccess(mlicensecheckercallback);     }      private class yahlicensecheckercallback implements licensecheckercallback {         public void allow(int policyreason) {             log.d(tag,"license - allowed");              if (isfinishing()) {                 // don't if activity finishing.                 return;             }             // should allow user access.          }          public void dontallow(int policyreason) {             log.d(tag,"license - not allowed");              if (isfinishing()) {                 // don't ui if activity finishing.                 return;             }              // should not allow access. in cases, app should assume             // user has access unless encounters this. if does,             // app should inform user of unlicensed ways             // , either shut down app or limit user             // restricted set of features.          }          public void applicationerror(int errorcode) {              log.d(tag,"license - application error code "+errorcode);              if (isfinishing()) {                 // don't update ui if activity finishing.                 return;             }             // polite way of saying developer made mistake             // while setting or calling license checker library.             // please examine error code , fix error.          }     }      @override     protected void ondestroy()     {     mchecker.ondestroy();     super.ondestroy();     } } 

ok, i've solved it. error 6 isn't coming licencevalidator, it's coming licensechecker , indicates permission missing. hadn't given app com.android.vending.check_license permission. when did, started working.

thanks interest , hope helps makes same mistake.
