更新到SDK版本21并更新我的支持库和构建工具后，我的生活今天一直在AWRY。因为，我的所有项目都不会构建导致R文件丢失。我稍后在2小时后修复了两个项目，并且更换了Jars来修复不匹配和重新启动的问题，但是并没有为其他项目工作。然后我运行了其中一个项目并继续抛出 NULL POINTER EXCEPTION ，我在那里调用getActionBar，然后我决定将其评论出来。在那里，我看到了原因。当我运行应用程序时，我再也看不到我的ActionBar了。然后，我尝试了第二个项目并且找不到PODy.apk！现在，我觉得已经死了。然后再从下面发现这些错误，我会看到我在Android终端中遇到的错误。任何帮助，将不胜感激。如果有人知道我可以在哪里获得AppCompat v20，那我真的很棒。

答案 0 :(得分：1)
您发布的错误消息的原因很可能是appcompat库的目标SDK版本设置为19而不是21。 API级别19中不存在Material属性，从而导致这些错误。
您应该更改它（在Eclipse中）：右键单击appcompat项目＆gt;属性＆gt; Android，并将Project Build Target设置为Android 5.0。
