BaseActivity mContext= this;
IntentUtils.changeActivity(mContext, MainActivity.class);

public static void changeActivity(Activity activity, Class<?> cls) {
Intent intent = new Intent();
intent.setClass(activity, cls);
activity.startActivity(intent);
activity.overridePendingTransition(R.anim.activity_right_in,
