permissions - Android “gps requires ACCESS_FINE_LOCATION” error -
i using sdk-23, , every time run application, securityexception gets thrown , error debugger reads so:
java.lang.securityexception: "gps" location provider requires access_coarse_location or access_fine_location permission.
this seems simple mistake, however, manifest file correct. here is, , here mapactivity code well:

if targeting android m, need ask users permission access device gps. here not clean code, might u little bit. better way create own permission manager class handle requests , alertdialog ativity.
whats happening below is
1) checking if permissions granted. 2) if not, checking if permissions have been denied previously, in case, showing rationale, explain user why need permissions. 3) show request permission popup using activitycompat. 4) if user declines, show snackbar view button take user app info screen, whenever u need access gps notice permissions not granted.
if (activitycompat.checkselfpermission(this, manifest.permission.access_fine_location) != packagemanager.permission_granted ) { if (activitycompat.shouldshowrequestpermissionrationale(this, manifest.permission.access_coarse_location)) { showrationale(); } else { // request permission activitycompat.requestpermissions(this, new string[]{manifest.permission.access_fine_location}, 8); } } @override public void onrequestpermissionsresult(int requestcode, string permissions[], int[] grantresults) { super.onrequestpermissionsresult(requestcode, permissions, grantresults); if (activitycompat.checkselfpermission(this, manifest.permission.access_fine_location) != packagemanager.permission_granted ){ //start code } else { //show snackbar } } } private void showrationale(){ string strdeletemessage = getresources().getstring(r.string.rationale_message11) ; final view dialogview = layoutinflater.from(this.getactivity()).inflate(r.layout.dialog_fragment, null); final alertdialog storagerationalealert = new alertdialog.builder(this.getactivity()).create(); storagerationalealert.setview(dialogview, 0, 0, 0, 0); storagerationalealert.setcanceledontouchoutside(false); textview mdialogtitle = (textview) dialogview.findviewbyid(r.id.dialog_title); textview mdialogdetails = (textview) dialogview.findviewbyid(r.id.dialog_details); mdialogdetails.setvisibility(view.visible); button mcancelbutton = (button) dialogview.findviewbyid(r.id.cancel_btn); button mokbutton = (button) dialogview.findviewbyid(r.id.ok_btn); mokbutton.settext(getstring(r.string.dialog_continue)); mdialogdetails.settext(html.fromhtml(strdeletemessage)); final activity activity = this.getactivity(); mokbutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { storagerationalealert.dismiss(); //ask gps permission } }); mcancelbutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { storagerationalealert.dismiss(); //show permission snackbar } }); storagerationalealert.show(); }
