java - How to ask multiple permissions at the same time in android 6.0+ -

i want ask user accept following permissions @ same time(one one), permissions like: checklocationpermission, checkreadsms, checkcallingpermission, checkreadstate, checkcontactwritestate. so, how can ask these permissions in first screen itself. please me out in regard. in advance.

you have first check user phone build version 23.

if (build.version.sdk_int >= build.version_codes.m) {     askpermissions(true); } else {     startactivity(new intent(permissionsactivity.this, splashactivity.class));     finish(); } 

if version 23 need ask permissions.

private void askpermissions(boolean isforopen) {     isrationale = false;     list permissionsrequired = new arraylist();      final list<string> permissionslist = new arraylist<string>();     if (!checkpermission(permissionslist, manifest.permission.write_external_storage))         permissionsrequired.add("write external storage");     if (!checkpermission(permissionslist, manifest.permission.call_phone))         permissionsrequired.add("call phone");     if (!checkpermission(permissionslist, manifest.permission.read_phone_state))         permissionsrequired.add("read phone state");     if (!checkpermission(permissionslist, manifest.permission.read_contacts))         permissionsrequired.add("read contacts");     if (!checkpermission(permissionslist, manifest.permission.receive_sms))         permissionsrequired.add("receive sms");     if (!checkpermission(permissionslist, manifest.permission.get_accounts))         permissionsrequired.add("get accounts");     if (!checkpermission(permissionslist, manifest.permission.access_coarse_location))         permissionsrequired.add("location");     if (!checkpermission(permissionslist, manifest.permission.access_fine_location))         permissionsrequired.add("location");      if (permissionslist.size() > 0 && !isrationale) {         if (permissionsrequired.size() > 0) {          }         if (isforopen) {             if (build.version.sdk_int >= build.version_codes.m) {                 activitycompat.requestpermissions(this, permissionslist.toarray(new string[permissionslist.size()]),                         11);             }         }      } else if (isrationale) {         if (isforopen) {              new android.support.v7.app.alertdialog.builder(this, r.style.appcompatalertdialogstyle)                     .settitle("permission alert")                     .setmessage("you need grant permissions manually. go permission , grant permissions.")                     .setpositivebutton("ok", new dialoginterface.onclicklistener() {                         @override                         public void onclick(dialoginterface dialog, int which) {                             dialog.dismiss();                             intent intent = new intent(settings.action_application_details_settings);                             uri uri = uri.fromparts("package", getpackagename(), null);                             intent.setdata(uri);                             startactivityforresult(intent, 123);                         }                     })                     .show();         }     } else {         startactivity(new intent(permissionsactivity.this, splashactivity.class));         finish();     } }  private boolean checkpermission(list permissionslist, string permission) {     if (build.version.sdk_int >= build.version_codes.m) {         if (contextcompat.checkselfpermission(this, permission) != packagemanager.permission_granted) {             permissionslist.add(permission);             // check rationale option             if (!isfirst) {                 if (!activitycompat.shouldshowrequestpermissionrationale(this, permission)) {                     isrationale = true;                     return false;                 }             }         }     }     return true; } 

on onrequestpermissionsresult need check permissions granted

@override public void onrequestpermissionsresult(int requestcode, @nonnull string[] permissions, @nonnull int[] grantresults) {     switch (requestcode) {         case 11:             map<string, integer> perms = new hashmap<string, integer>();             // initial             perms.put(manifest.permission.write_external_storage, packagemanager.permission_granted);             perms.put(manifest.permission.call_phone, packagemanager.permission_granted);             perms.put(manifest.permission.read_phone_state, packagemanager.permission_granted);             perms.put(manifest.permission.read_contacts, packagemanager.permission_granted);             perms.put(manifest.permission.receive_sms, packagemanager.permission_granted);             // fill results             (int = 0; < permissions.length; i++) {                 perms.put(permissions[i], grantresults[i]);             }             // check access_fine_location             if (perms.get(manifest.permission.write_external_storage) == packagemanager.permission_granted &&                     perms.get(manifest.permission.call_phone) == packagemanager.permission_granted &&                     perms.get(manifest.permission.read_phone_state) == packagemanager.permission_granted &&                     perms.get(manifest.permission.read_contacts) == packagemanager.permission_granted &&                     perms.get(manifest.permission.receive_sms) == packagemanager.permission_granted) {                 // permissions granted                 startactivity(new intent(permissionsactivity.this, splashactivity.class));                 finish();             } else {                 // permission denied                 toast.maketext(this, "some permission denied.", toast.length_short)                         .show();                 isfirst = false;                 askpermissions(true);             }             break;         default:             super.onrequestpermissionsresult(requestcode, permissions, grantresults);      } } 

if user has set permission never ask again application setting screen open. user allow/deny permission there. need check again on activityresult.

@override protected void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);     askpermissions(true); }
