geolocation - CheckPermissions Error for LocationManager in Android Studio -

-

i had working app getgeolocation api level 23( using checkselfpermission). but, had make compatible api level 21. so, checkselfpermission didn't work introduced in api level 23.

so, changed code accomodate this:

 protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     checkforcoarselocationpermission();  } private void checkforcoarselocationpermission() {     if (android.os.build.version.sdk_int >= 23)     {         // android 6.0 , up!         boolean accesscoarselocationallowed = false;         try         {             // invoke checkselfpermission method android 6 (api 23 , up)             java.lang.reflect.method methodcheckpermission = activity.class.getmethod("checkselfpermission", java.lang.string.class);             object resultobj = methodcheckpermission.invoke(this, manifest.permission.access_coarse_location);             int result = integer.parseint(resultobj.tostring());             if (result == packagemanager.permission_granted)             {                 accesscoarselocationallowed = true;               }         }         catch (exception ex)         {         }         if (accesscoarselocationallowed)         {             log.v("tag","granted");             locationmanager locationmanager=    (locationmanager)getsystemservice(context.location_service);                 locationmanager.requestlocationupdates(locationmanager.gps_provider, 0, 0,new locationlistener());//error happening here!!!!!!!!!!!         }         try         {             // have invoke method "void requestpermissions (activity activity, string[] permissions, int requestcode) "             // android 6             java.lang.reflect.method methodrequestpermission = activity.class.getmethod("requestpermissions", java.lang.string[].class, int.class);             methodrequestpermission.invoke(this, new string[]                     {                             manifest.permission.access_fine_location                     }, 0x12345);         }         catch (exception ex)         {         }     } }

now, locationmanager.requestlocationupdate giving error call requires permission may rejected user: code should explicitly check see if permission available (with checkpermission) or explicitly handle potential securityexception less

how tackle it, if want use locationmanager , checkpermission api level >=21.

kindly, help.

try this

if (contextcompat.checkselfpermission(this, manifest.permission.access_coarse_location) == packagemanager.permission_granted) { // coarse permission granted             // todo } else { // permission not granted, request permission     if (activitycompat.shouldshowrequestpermissionrationale(this, manifest.permission.access_coarse_location)) { // show info user why want permission        toast.maketext(this, "allow location permission use functionality.", toast.length_short).show();        activitycompat.requestpermissions(this, new string[]{manifest.permission.access_fine_location, manifest.permission.access_coarse_location}, 123 /*location_permission_request_code*/);     } else {        activitycompat.requestpermissions(this, new string[]{manifest.permission.access_fine_location, manifest.permission.access_coarse_location}, 123 /*location_permission_request_code*/);      } }

note:- must have following permission in android manifest

<uses-permission android:name="android.permission.access_coarse_location" />
