android - Runtime permission with 2 request in the same activity -

i'm trying ask 2 runtime permissions int same activity. first 1 trigger button , ask read_contacts, if allowed go forward via onactivityresult. other runtime permission ask send_sms , if allowed go onrequestpermissionsresult. now, understand how workd - i'm doing wrong. 2 runtime permissions need run through 1 of choices , need build method switch case or handle 2 permissions won't crash. need idea how handle 2 events won't allow contacts permission , activity try run sms method.

that's onactivityresult override can't rid of.

@override protected void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);     try {         if (requestcode == request_code_pick_contacts && resultcode == result_ok) {             log.d(tag, "response: " + data.tostring());             uricontact = data.getdata();              retrievecontactnumber();         }     }     catch (exception e){         e.getstacktrace();         toast.maketext(smsactivity.this, "hi, tried :p", toast.length_short).show();     } }    private void retrievecontactnumber() {      cursor cursorid = getcontentresolver().query(uricontact, new string[]{contactscontract.contacts._id}, null, null, null);      if (cursorid.movetofirst()) {          contactid = cursorid.getstring(cursorid.getcolumnindex(contactscontract.contacts._id));     }      cursorid.close();      log.d(tag, "contact id: " + contactid);       cursor cursorphone = getcontentresolver().query(contactscontract.commondatakinds.phone.content_uri,             new string[]{contactscontract.commondatakinds.phone.number},              contactscontract.commondatakinds.phone.contact_id + " = ? , " +                     contactscontract.commondatakinds.phone.type + " = " +                     contactscontract.commondatakinds.phone.type_mobile,              new string[]{contactid},             null);      if (cursorphone.movetofirst()) {         contactnumber = cursorphone.getstring(cursorphone.getcolumnindex(contactscontract.commondatakinds.phone.number));     }      cursorphone.close();     txtcbnum = (edittext) findviewbyid(r.id.txtnum);     txtcbnum.settext(contactnumber, textview.buffertype.editable);      log.d(tag, "contact phone number: " + contactnumber); }   private void requestsmspermission() {      if (contextcompat.checkselfpermission(smsactivity.this, manifest.permission.send_sms) != packagemanager.permission_granted) {         activitycompat.requestpermissions(smsactivity.this,                 new string[]{manifest.permission.send_sms},                 permission_send_sms);     } else {         contactnumber = txtcbnum.gettext().tostring();         sendsms(contactnumber, dibur);     }   }  @override public void onrequestpermissionsresult(int requestcode, string permissions[], int[] grantresults) {      if (requestcode == permission_send_sms) {          contactnumber = txtcbnum.gettext().tostring();          sendsms(contactnumber, dibur);     } else if (requestcode == my_permissions_request_read_contacts) {         try {             // need insert contact number retrieve here          } catch (exception e) {             e.getstacktrace();             toast.maketext(smsactivity.this, "hi, tried :p", toast.length_short).show();         }     } else {         toast.maketext(smsactivity.this, "permission denied, can't send sms.", toast.length_long).show();     }  }   private void sendsms(string phonenumber, string message) {     try {         smsmanager sms = smsmanager.getdefault();         sms.sendtextmessage(phonenumber, null, message, null, null);         toast.maketext(smsactivity.this, "sms sent " + contactnumber, toast.length_short).show();     } catch (exception e) {         toast.maketext(smsactivity.this, "sms failed, please try again." + contactnumber, toast.length_long).show();         e.printstacktrace();     } } 

you can tell 2 requestpermissions() calls apart integer passing second parameter. value supplied onrequestpermissionsresult() parameter.

so, example, if in 1 place have:

activitycompat.requestpermissions(this, ..., result_perms_record_video); 

(with array of permission names ...)

and in place have:

activitycompat.requestpermissions(this, ..., result_perms_take_picture); 

(with, presumably, different array of permission names ...)

then can have:

  @override   public void onrequestpermissionsresult(int requestcode,                                          string[] permissions,                                          int[] grantresults) {     if (requestcode==result_perms_take_picture) {       //     }     else if (requestcode==result_perms_record_video) {       // else     }   }
