android - onRequestPermissionsResult is not being called -

i want ask permission write external storage marshmallow. can't see option override onrequestpermissionsresult. able call requestpermissions. have created below method. now, want call new action based on result. please me go ahead.

public static boolean verifypermissions(activity activity,             string[] grantresults) {         boolean allpermissionsgranted = true;          if (build.version.sdk_int >= build.version_codes.m) {             (string result : grantresults) {                 int outresult = activity.checkselfpermission(result);                 if (outresult != packagemanager.permission_granted) {                     allpermissionsgranted = false;                     break;                 }             }              if (!allpermissionsgranted) {                 activity.requestpermissions(grantresults, 1);             }         }          return allpermissionsgranted;     } 

i have fragment. tried below code directly showing error 'the method onrequestpermissionsresult(int, string[], int[]) of type products must override or implement supertype method'.

code :

@override     public void onrequestpermissionsresult(int requestcode,             @nonnull string[] permissions, @nonnull int[] grantresults) {      } 

i can't see option override onrequestpermissionsresult.

you override on activity passing method.
