无法使用GetIntExtra整数值进行计算

Question

MainClass.java

                Intent i;
                i = new Intent(v.getContext(), Next.class);
                i.putExtra("increment1",1);
                v.getContext().startActivity(i);

Next.java

 Intent mIntent = getIntent();
        int age=mIntent.getIntExtra("increment1", 0);
        String age1=Integer.toString(age);
        Toast.makeText(this,age1, Toast.LENGTH_LONG).show();

当我在吐司中使用变量年龄时，我遇到了错误。这意味着，我不能使用Integer值。请帮我使用整数值。
