代碼你已經給FourGamers.java只有20行，但異常表明行31 ... –

對不起，我刪除了默認標題:)現在增加了一個完整的。 –

看着爲CordobaActivity的源代碼，我懷疑的問題是，你正在使用loadUrl你叫super.onCreate之前，這意味着活動的各個方面不勾搭上了呢。我建議您切換輪線，這一點：

super.onCreate(savedInstanceState); 
super.setIntegerProperty("splashscreen", R.drawable.splash); 
super.loadUrl(Config.getStartUrl(), 10000);

（爲什麼你調用super.loadUrl(Config.getStartUrl())兩次，順便目前尚不清楚 - 沒有一次因超時而一旦...）

這似乎解決了它。謝謝你，喬恩。 –
