有时你使用Eclipse创建完成Android工程后,会需要更改support,你可以参见这里:
- Make sure you have downloaded the Android Support Library using the SDK Manager .
- Create a
libs/
directory in the root of your application project. - Copy the JAR file from your Android SDK installation directory (e.g.,
<sdk>/extras/android/support/v4/android-support-v4.jar
) into your application’s projectlibs/
directory. - Right click the JAR file and select Build Path > Add to Build Path .
