i'm pretty confused, 'cause seems granted required permissions. please give me piece of advice. thanks!

try change code.

// add marker in sydney , move camera latlng sydney = new latlng(-34, 151); mmap.addmarker(new markeroptions().position(sydney).title("marker in sydney")); mmap.movecamera(cameraupdatefactory.newlatlng(sydney)); if (activitycompat.checkselfpermission(this, android.manifest.permission.access_fine_location) != packagemanager.permission_granted && activitycompat.checkselfpermission(this, android.manifest.permission.access_coarse_location) != packagemanager.permission_granted) return; mmap.setmylocationenabled(true); mmap.getuisettings().setmylocationbuttonenabled(true);
