1.android ERROR: unknown virtual device name解决办法
打开系统属性-->环境变量—>在“系统变量”那一个GroupBox下面选择“新建”-->变量名为 "ANDROID_SDK_HOME” (注意,这个变量名不能改变,只能是这个名字!),然后 把变量值改为你想把AVD所在的".android”文件夹放置的位置,比如:"F:\AndroidEmulator”,在这里我把它放在 Android SDK包中,值为:"D:\SDK\Android\android-sdk- windows-1.5_r3”,如下图所示. 设定成功的话 ,在eclipse里preferneces -> Android -> Bulid Setting里为如下结果:Default debug keystore: F:\Android_Emulator\\.android\debug.keystore 然后这样就可以一劳永逸了!
2.emulator-5554 disconnected! Cancelling 'oms.Hello.HelloOpone' launch!
在eclipse里面改变一下你run的时候的设置就好了.
右点你的工程后run里面有一个run configrations,
在里面有一个选项每次运行都察掉记录 wipe.的,选上就好了.
