uses

System.Permissions,

{$IFDEF ANDROID}

Androidapi.Jni.Os,

Androidapi.Helpers,

{$ENDIF}

...

FPermissionCoarseLocation: string;

FPermissionFineLocation: string;

...

procedure TMainForm.FormCreate(Sender: TObject);

begin

{$IFDEF ANDROID}

// Note we can alternatively use literal strings:

// ‘android.permission.ACCESS_COARSE_LOCATION‘

// ‘android.permission.ACCESS_FINE_LOCATION‘

// according to the documentation:

// https://developer.android.com/reference/android/Manifest.permission#ACCESS_COARSE_LOCATION

// https://developer.android.com/reference/android/Manifest.permission#ACCESS_FINE_LOCATION

FPermissionCoarseLocation := JStringToString(TJManifest_permission.JavaClass.ACCESS_COARSE_LOCATION);

FPermissionFineLocation := JStringToString(TJManifest_permission.JavaClass.ACCESS_FINE_LOCATION);

{$ENDIF}

end;

procedure TMainForm.Button1Click(Sender: TObject);

begin

PermissionsService.RequestPermissions([FPermissionCoarseLocation, FPermissionFineLocation], LocationPermissionRequestResult);

end;
