What is this mistake and why does it occur? None of these classes are in my application (like com.olivephone.edit.update.OfficeChecker ).

 ERROR/WindowManager(16794): Activity com.olivephone.edit.update.OfficeChecker has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@408bc380 that was originally added here android.view.WindowLeaked: Activity com.olivephone.edit.update.OfficeChecker has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@408bc380 that was originally added here at android.view.ViewRoot.<init>(ViewRoot.java:288) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:249) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:193) at android.view.WindowManagerImpl$CompatModeWrapper.addView(WindowManagerImpl.java:118) at android.view.Window$LocalWindowManager.addView(Window.java:532) at android.app.Dialog.show(Dialog.java:269) at android.app.ProgressDialog.show(ProgressDialog.java:115) at android.app.ProgressDialog.show(ProgressDialog.java:103) at com.olivephone.edit.update.OfficeChecker.onCreate(OfficeChecker.java:54) at android.app.Activity.performCreate(Activity.java:4397) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1048) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1779) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1831) at android.app.ActivityThread.access$500(ActivityThread.java:122) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1024) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:132) at android.app.ActivityThread.main(ActivityThread.java:4123) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:491) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:841) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:599) at dalvik.system.NativeStart.main(Native Method)

    Each window has its own parent, if the parent is closed before the child is closed, an error occurs: window leak - a window leak. Usually this occurs when a dialogue is created from the activation, then the activation is closed, and the dialogue remains to hang (in reality, the window system closes it anyway).

    Accordingly, the error indicates the place where the dialogue was added so that the developer can correctly handle this place.

    The error is non-lethal, but unpleasant.
