本文介绍了一个关于在Android的TabActivity中绑定服务时遇到的问题及解决方案。当将绑定服务的活动设置为标签内容时，服务的onBind方法不会被调用。文章提供了解决方案：使用getApplicationContext().bindService替代普通的bindService方法。

To reproduce:

1) Create class that extends TabActivity
2) on the tabHost add a tab which has content set to an activity which
binds to a service via IPC

The activity binds fine normally but not when used as tab content.

DDMS reports (in my case):
ActivityManager::Binding with unknown activity: android.os.BinderProxy@436dd168

Log messages in the service verifies that the onBind method is never called.

Using getApplicationContext().bindService instead of just bindService on your
activity solves the problem as it is using the higher level application context.

Comment 6 by sashib, Apr 17, 2010 god bless you oliver, took me a whole day to find this thread and the getApplicationContext() solved the issue... 
wish they would cover this better in the docs
