I'm new with Android and the project appcompat_v7 always be created when I create new Android application project makes me so uncomfortable. This is just a walk around. Choose Project Properties -> Android then at Library box just remove appcompat_v7_x and add appcompat_v7. Now you can delete appcompat_v7_x. Uncheck Create Activity in create project wizard doesn't work, because when creating activity by wizard the appcompat_v7_x appear again. My ADT's version is v22.6.2-1085508. I'm sorry if my English is bad.

如果你的目标不是2。X版本，你可以设置你的最低SDK版本为4。X，然后创建项目。不会创建Appcompat V7库。

我注意到在创建ADT 22.6.2版本的新android项目时创建了“appcompat”库，即使minSDK设置为11,targetSDK设置为19

这是因为，在新的项目模板中，android正在使用一些来自支持库的属性。例如，如果一个新项目是用actionbar创建的，那么在菜单的main.xml中，你可以从支持库中找到app:showAsAction="never"。

If the app is targeted at android version 11 and above then one can change this attribute to android:showAsAction in menu's main.xml Also the default theme set could be "Theme.AppCompat.Light.DarkActionBar" as shown below (styles.xml) <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- API 14 theme customizations can go here. --> </style> In this case the parent theme in style.xml has to be changed to "android:style/Theme.Holo.Light.DarkActionBar" In addition to this if reference to Fragment,Fragments Manager from support library was made in the code of MainActivity.java, these have to appropriately changed to Fragment, FragmentManager of the SDK.

之所以包含它，是因为您的最低SDK版本设置为10。ActionBar是在API 11中引入的。Eclipse会自动添加它，这样你的应用就能在你支持的所有android版本中看起来更加一致。

创建一个新的Android应用程序项目，取消第二步(配置项目)中的创建活动。
