我在android api版本8上构建了一个应用程序，我选择这个选项，因为我认为它可以在较新版本的Android中运行，但是当我尝试按照我在标题中提到的那样做时，我的应用程序强制关闭。应用程序启动并正常工作，只有菜单inflater中的错误，这是我的代码：
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
Toast.makeText(this, "About Developer", Toast.LENGTH_LONG).show();
Intent i = new Intent(this, about.class);
startActivity(i);
return true;
}
有没有人有任何想法解决它？
