step 2: Archive

this step  produce an APK.

right click your Android project and select "Archive..."

Step 3：Distribute

Step 4：AdHoc

Step 5：Sign

要执行这一步，是因为：


Android 系统要求安装的每个应用都必须使用应用开发者拥有的证书（即开发者用于存放私钥的证书）进行数字签名。

Android 系统利用该证书来识别应用作者并在应用之间建立信任关系。您用于签名的的证书无需由证书授权机构签名；

Android 系统允许您使用自签名证书为您的应用签名。

Step 6：Save As
