Location Manager

Arkadaşlar hepinize iyi kodlamalar. Benim bir sorunum var. Uygulamamda konum bilgisini almaya çalışıyorum. Kodlamamda sıkıntı yok. İzinleride android 6.0 üstü ne uygun hale getirdim. Ancak bende samsung S4 android 5.0.1 cihazda konum bilgisini alıyorum. Ama GM 5 Plus android 7.0 da alamıyorum. Birde emilatör 4.4 kitkat da konum bilgisi alamıyorum. nedendir. Acaba.

public class MainPermission {

    Activity activity = null;
    String[] permissions = null;

    public MainPermission(Activity activity, String[] permissions) {
        this.activity = activity;
        this.permissions = permissions;
    }

    public boolean check() {
        if (ContextCompat.checkSelfPermission(this.activity, this.permissions[0]) != PackageManager.PERMISSION_GRANTED) {
            return false;
        } else {
            return true;
        }
    }

    public void request(String message, final int permissionCode) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(activity, R.style.AlertDialogStyle);
        builder.setTitle("Test uygulaması");
        builder.setMessage(Html.fromHtml(message));
        builder.setPositiveButton("Anladım", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    activity.requestPermissions(permissions, permissionCode);
                }
            }
        });
        AlertDialog dialogPermissions = builder.create();
        dialogPermissions.show();
    }
}
