我最近更新日食，SDK和我的问题是

I recently updated eclipse, SDK and my problems are

在默认情况下，需要 fragment_main.xml 在扩展默认活动 ActionBarActivity 在默认情况下它被添加库 appcompat 7 By default it takes fragment_main.xml Extends default activity to ActionBarActivity By default it is adding the library appcompat 7

我没有任何问题，增加了图书馆，但是当我试图运行，那么它是不是在执行设备（2.3版Android）。我注意到了这一点，并改为活动。

I dont have any issues with adding the library, but when i am trying to run then it is not executing in the device(2.3 android). I noticed it and changed to Activity.

如果我将其扩展到活动并运行它，然后重新下一次，同时创造新的活动一样......同样的问题出现了。

If i extends it to Activity and run it and again for the next time the same problem arises while creating new Activity like...

2创建XML文件扩展ActionBarActiity。

Creating 2 xml files with extending ActionBarActiity.

我只希望新的类来扩展活动而不是 ActionBarActivity 在我的目标设备是2.3及以上的无降级它

I just want the new class to extend Activity but not ActionBarActivity where my target device is 2.3 and above without downgrading it

推荐答案

它有SDK V4.4。这是一个加点的开发，因为开发者不需要手动添加ActionBarActivity到他们的项目。有两个解决您的问题。

It comes in SDK v4.4 . It is a plus point for developers because developers don't need to manually add the ActionBarActivity into their project. There are two solutions for your problem.

降级SDK 4.3或更低。     或 删除ActionBarActivity和你的java文件扩展活动。 Downgrade your SDK to 4.3 or lower. or Remove ActionBarActivity and extends Activity in your java file.

这两个会为你工作。
