FragmentActivity在onStart中崩潰

由於某種原因，我的應用程序在super.onCreate中發生nullPointerException異常。其擴展fragmentActivity的活動。FragmentActivity在onStart中崩潰

public class LiveMatchActivity extends FragmentActivity

這就是我在onStart（）：

@Override 
protected void onStart() { 
    super.onStart(); 
    Analytics.getIntance().trackStart(this); 
}

當我到達super.onStart()應用壓碎。

這就是日誌：

什麼可能呢？

什麼是事件片段中的第211行 – stinepike

http://stackoverflow.com/a/9857669/1168654和http://stackoverflow.com/a/6253664/1168654 –

代碼中沒有進入第211行。應用程序粉碎在super.onStart（）你爲什麼問？ – roiberg

及其對super.onStart（）不崩潰有在 com.ftbpro.app.EventsFragment.filterAndSortEventsList（EventsFragment.java:211）這裏

問題

如果您可以粘貼EventsFragment.java文件的代碼，我們可以嘗試以更好的方式幫助您。
