几天前我遇到了同样的问题，并发现与 APK 签名相关的事情表现得很奇怪.解决方案是将自定义调试密钥库"设置(默认为空)设置为与 Eclipse 首选项中的默认调试密钥库"相同的值.

I was facing the same issue a couple of days ago and figured out that something related to APK signing was acting weird. The solution was to set the "Custom debug keystore" setting (empty by default) to the same value as the "Default debug keystore" in the Eclipse preferences.
