onRequestPermissionsResult is not called in fragment android -

i taking runtime permission user using below code in fragment .

if (contextcompat.checkselfpermission(getactivity(),                                     manifest.permission.read_external_storage)                                     != packagemanager.permission_granted) {                                   activitycompat.requestpermissions(mactivity,                                         new string[]{manifest.permission.read_external_storage},                                         storage_permission_code);                               } 

and overriding

@override     public void onrequestpermissionsresult(int requestcode,                                            string permissions[], int[] grantresults) {         switch (requestcode) {             case 21: {                  // if request cancelled, result arrays empty.                 if (grantresults.length > 0                         && grantresults[0] == packagemanager.permission_granted) {                      // permission granted, yay!                     // contacts-related task need do.                     } else {                      // permission denied, boo! disable                     // functionality depends on permission.                     toast.maketext(getactivity(), "permission denied", toast.length_short).show();                 }                 return;             }              // other 'case' lines check other             // permissions app might request         }     } 

but override method not called

please give me hint have override in fragment

becouse remember futher u must in activity not in fragment. yoou can d tricky in fragment bad way

this in activity. check permissions , save it

private static final int request_code_get_accounts = 101;     private static final int request_audio_permission = 102;   @targetapi(23) public void checkaudiopermission() {     if (build.version.sdk_int < build.version_codes.m) {         playerfragment.setupvisualizerfxandui();         return;     }     if (this.checkselfpermission(manifest.permission.record_audio) != packagemanager             .permission_granted) {         requestpermissions(new string[]{manifest.permission.record_audio},                 request_audio_permission);     } else {         playerfragment.setupvisualizerfxandui();     } }  @targetapi(23) public void checkgmailpermission() {     if (isdeviceonline()) {         if (build.version.sdk_int < build.version_codes.m) {             showgmailrecfragment(true);             return;         }         if (this.checkselfpermission(manifest.permission.get_accounts) != packagemanager                 .permission_granted) {             requestpermissions(new string[]{manifest.permission.get_accounts},                     request_code_get_accounts);             return;         } else {             showgmailrecfragment(true);         }     } else {         utils.showtoast(this, getstring(r.string.no_internet));     } }  @override public void onrequestpermissionsresult(int requestcode, string[] permissions, int[]         grantresults) {     switch (requestcode) {         case request_code_get_accounts:             if (grantresults[0] == packagemanager.permission_granted) {                 showgmailrecfragment(true);             } else {                 utils.showtoast(this, getstring(r.string.accounts_permision_denied));             }             break;         case request_audio_permission:             if (grantresults[0] == packagemanager.permission_granted) {                 playerfragment.setupvisualizerfxandui();             } else {                 utils.showtoast(this, getstring(r.string.audio_permission_denied));             }         default:             super.onrequestpermissionsresult(requestcode, permissions, grantresults);             break;     } } 

and on fragment when want check permission again or if user denied it. save permissions

private void setupviewvisualizer() {     if (!islivetv && !homevideo.isvideotype()) {         ((playeractivity) activity).checkaudiopermission();     } else {         return;     } }
