Android的Context.bindService始终返回false和ServiceConnection对象永远不会触发 [英] Android Context.bindService always returns false and ServiceConnection object is never triggered

问题描述

我跟href="http://developer.android.com/reference/android/app/Service.html#LocalServiceSample">本地服务例如通过谷歌提供的上下文:: bindService（...）总是返回false并有 ServiceConnection :: onServiceConnected 也从来没有所谓。

I have followed the Local Service example provided by Google, but my Context::bindService(...) always returns false and there is ServiceConnection::onServiceConnected is also never called.

据我所知，上下文:: bindService（）立即返回，但我的 ServiceConnection 对象永远不会触发。

I understand that Context::bindService() returns immediately, but my ServiceConnection object is never triggered.

我不知道，如果这些申请

I don't know if these apply

1. 在我的活动运行内部tabHost，我想知道是否会影响服务以任何方式结合。
2. 在服务本身可能有问题，但我可以调用start服务，同样的服务具有相同意图和它的作品如预期。

1. My activity is running inside a tabHost and I was wondering if that can affect service binding in any way.
2. The Service itself may have a problem, but I can call start service to the same service with the same Intent and it works as expected.

有没有人有这样的经历？请帮我。

Does anyone have experience with this? Please help me out.

谢谢， 附：我瞄准了Android 1.6

Thanks, P.S. I am targeting Android 1.6

推荐答案

所以，我终于想通了。事实证明，则tabspec不能绑定到活动

So I finally figured it out. It turns out that TabSpec cannot bind to activities

使用，而不是仅仅bindService上getApplicationContext（）。bindService您   活动解决了这个问题，因为它是使用较高等级的应用的上下文

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