[Android] java.io.FileNotFoundException AND android.os.NetworkOnMainThreadException!!

1.Android 4.0 has a new Exception in NetWork part.So if you request it.
You will get a android.os.NetworkOnMainThreadException!!

Android4.0在網路的部份多了一個新的Exception，
叫做android.os.NetworkOnMainThreadException
意思就是說：網路的活動跑在主要執行緒上了，很貼心的告訴你，這樣子你的APP可能會因為網路的活動等待回應太久，而被系統強制關閉（收到ANR）。

Solution:(put it in main )
StrictMode
    .setThreadPolicy(new StrictMode.ThreadPolicy.Builder()  
    .detectDiskReads()  
    .detectDiskWrites()  
    .detectNetwork()   // or .detectAll() for all detectable problems  
    .penaltyLog()  
    .build());

Java.io.FileNotFoundException

4.0中設置httpCon.setDoOutput(true),将導致請求以post方式提交
然後就會出現 java.io.FileNotFoundException

Soluation:
Delete-->httpCon.setDoOutput(true);
