"an existing package with the same name with a conflicting signature is already installed." “已经安装了具有冲突签名的同名现有软件包。”

The reason might be because you previously installed a debug version on your device which has a default key used by that debug version.原因可能是因为您之前在设备上安装了调试版本，该版本具有该调试版本使用的默认密钥。 Releasing a new version with your signature doesn't match the debug key so you get that warning and should uninstall current version before installing the new one.使用您的签名发布新版本与调试密钥不匹配，因此您会收到该警告，并且应该在安装新版本之前卸载当前版本。

The key is关键是
...of my application in eclipse with own signature...
if the signature is different than you used before, for any reason, you cannot install application with the same id (package name), unless you uninstall the old app first.如果签名与您之前使用的不同，无论出于何种原因，您都无法安装具有相同 ID（包名称）的应用程序，除非您先卸载旧应用程序。
