当我尝试从facebook登录时收到电子邮件。我有例外：没有电子邮件的价值。然后剩下的代码没有执行。我的意思是HTTPParams代码没有执行。我给了电子邮件权限以获取电子邮件但有些用户的facebook电子邮件没有收到。这是我的代码

您可以将try catch块与finally语句一起使用。执行try-catch块直到捕获到异常，然后执行finally块。

try {// executes until exception

    } catch ( ){ // executes only if exception is thrown

    } finally { // always gets called

    }
