Android ICS兼容性

我有幾個項目，我正式轉移到ICS和有一些奇怪的兼容性問題。這兩個項目在Androdid 2.2和2.3中運行良好。這兩個項目原本在清單如下：使用java.netAndroid ICS兼容性

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="10" />

我連接到我的新的ICS設備後，並運行我有一些的Java API（包含在項目的jar文件）的錯誤。套接字和java.io. *等等。當我從清單中刪除android：targetSdkVersion =「10」時，事情開始在ICS中重新開始工作。然而，有一些性能問題，下面顯示了在Eclipse DDMS logcat的頗有幾分：

threadid=3: reacting to signal 3 
Wrote stack traces to '/data/anr/traces.txt'

這裏是traces.txt輸出：

誰能幫我指出正確的方向嗎？

你可能想提一提你做了什麼「搬家」到ICS 。您是否更改了您正在搭建的Android版本？更改目標版本可能會在運行時產生影響，但不會導致編譯錯誤。重新檢查你的項目設置。 – 2012-04-24 13:50:09

查看android.os.NetworkOnMainThreadException您可能在允許蜂窩前的UI線程上執行網絡操作，但現在會引發異常。 – Kuffs 2012-04-24 13:59:52

要獲取跟蹤文件，請使用'adb pull/data/anr/traces.txt'命令。 – Goldsmith 2012-04-24 14:03:04

退房android.os.NetworkOnMainThreadException你可能這是允許的預蜂窩狀的UI線程上執行網絡操作，但是現在拋出一個異常

我已經部分實現AsyncTask（http://developer.android.com/reference/android/os/AsyncTask.html）圍繞我的一些網絡相關的代碼並且它已經開始表現得很好了！ :) – 2012-04-24 15:42:46

連接亞行logcat工具來看看會發生什麼......這也是Eclipse插件的一部分，如果它沒有在工作區中顯示出來，然後剛剛經歷窗口 - 啓用>顯示視圖>其他並找到根據Android的部分logcat的
