23.在使用AndroidHttpClient时有如下错误：01-16 22:18:39.222: E/AndroidHttpClient(26745): java.lang.IllegalStateException: AndroidHttpClient created and never closed?这个主要是因为没有调用AndroidHttpClient的close()方法。它的close()方法如下：?12345678910/**?*?Release?resources?associated?with?this?client.??You?must?call?this,?*?or?significant?resources?(sockets?and?memory)?may?be?leaked.?*/public?void?close()?{????if?(mLeakedException?!=?null)?{????????getConnectionManager().shutdown();????????mLeakedException?=?null;????}}在我们的使用中在finally语句块中调用其close方法即可。?12345finally?{????if(httpClient?!=?null)?{????????httpClient.close();????}}? ? ?最后更新：2012－11－1223,在使用一个FrameLayout作为容器时，将一个Frament实例动态添加进布局时，出现如下错误提示：The specified child already has a parent. You must call removeView() on the childs parent first.解决办法就是：在Overridepublic?View?onCreateView(LayoutInflater?inflater,?ViewGroup?container,????????Bundle?savedInstanceState)?{????Log.i(DIALOG_FRAGMENT,?====（3）onCreateView========);????View?view?=?inflater.inflate(R.layout.auth,?container,?false);????initViews(view);????return?view;}中，使用，注意带参数falseView view = inflater.inflate(R.layout.auth, container, false);22.android:filterTouchesWhenObscured?view所在窗口被其它可见窗口遮住时，是否过滤触摸事件。?结果因为有些应用会在界面的上面加一层，导致软件不可滑动。所以。最后更新 2012-04-28?21.接下面的错误:?1234567891011121314151617181920212205-10?16:16:23.830:?W/dalvikvm(15086):?threadid=1:?thread?exiting?with?uncaught?exception?(group=0x40a4b1f8)05-10?16:16:23.860:?E/AndroidRuntime(15086):?FATAL?EXCEPTION:?main05-10?16:16:23.860:?E/AndroidRuntime(15086):?java.lang.IllegalStateException:?Activity?has?been?destroyed05-10?16:16:23.860:?E/AndroidRuntime(15086):???? at?android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1314)05-10?16:16:23.860:?E/AndroidRuntime(15086):???? at?android.support.v4.app.BackStackRmitInternal(BackStackRecord.java:541)05-10?16:16:23.860:?E/AndroidRuntime(15086):???? at?android.support.v4.app.BackStackRmitAllowingStateLoss(BackStackRecord.java:529)05-10?16:16:23.860:?E/AndroidRunt
