Question

我知道这个异常已经反复讨论过，但不知怎的，我无法解决这个问题。我前段时间制作了一个应用程序（BeerOrNoBeer Drinkinggame）并将其发布在Google Play商店中，但在我切换到新的笔记本电脑后，我无法使其正常工作。该应用程序启动进入菜单，甚至进入GameActivity和AboutActivity。但是，当我尝试打开SendBeerBrandActivity或按下OnScreen Backbutton App强制停止..

如果有人可以提供帮助，我会非常感激，所以我终于可以做出期待已久的更新。

我在Github上有整个代码Beer Or No Beer

此功能打开新活动：

public void sendbeer(){
    Intent gosendbeer  = new Intent("com.celticwolf.alex.SENDBRAND");
    startActivity(gosendbeer);
}

这是按下按钮以启动“SendBeerBrand”后的错误日志。
