推荐答案
解决方法在Eclipse / Android的问题的 20990 为我工作。
Workaround related in Eclipse / Android issue 20990 works for me.
这似乎并没有发生在第一次发射。我有我的启动配置设置为始终询问的装置;这似乎发生无论是作为或作为一个理由对话框没有出现在我的一些尝试重新推出的结果。
this does not seem to occur upon first launch. i have my launch config set to "Always Ask" for the device; this seems to occur either as a result of or as a reason for that dialog not appearing on some of my attempts to re-launch.
