ViewRoot$CalledFromWrongThreadException 和内存泄漏

Activity XXX.XXX has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@46021980 that was originally added here
01-15 14:48:13.153: E/WindowManager(6360): android.view.WindowLeaked: Activity  XXX.XXX has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@46021980 that was originally added here

以上内存泄漏，有一种情况是Activity释放时，基于它的Dialog等没有释放导致的。

android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views

UI的更新只能在UI线程，也就是主线程中更新，否则就会产生如上错误。
