导入外部工程,运行发现问题,求指导
我刚开始学Android,网上找了个工程,导入之后运行结果出现以下错误提示:
[2012-08-30 14:35:00 - Emulator] WARNING: Data partition already in use. Changes will not persist!
[2012-08-30 14:35:00 - Emulator] WARNING: SD Card image already in use: D:\han.cai\.android\avd\4.1.avd/sdcard.img

我结束adb.exe进程重启Eclipse后还是这样,我Eclipse里面有两个AVD一个2.2的另外一个是4.1的平时都是建立2.2的工程,这个网上的工程是4.1的,就无法运行,我在运行配置里面的Target里面选择了4.1的还是不行,不知道为什么

------解决方案--------------------
应该是你avd4.1 建的有问题吧，把项目改用2.2试试呢，或者在manifest文件里加上这句话：
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="8" />

------解决方案--------------------
把4.1的模拟器删除试试！！！
