安卓中“UserManger.isUserAGoat()”的合适案例?

问题描述

我正在看在安卓4.2里介绍的新API。当看到“UserManger”类时,我遇到了如下的“method”: public boolean isUserAGoat() Used to determine whether the user making this call is subject to teleportations.

Returns whether the user making this call is a goat. 这个应该怎样使用和什么时候使用?

回答

根据他们的资料,在API21前,这个“method”用来返回“false” /**

  • Used to determine whether the user making this call is subject to
  • teleportations.
  • @return whether the user making this call is a goat */ public boolean isUserAGoat() { return false; } 看起来这个“method”对我们开发者没有真正的用途。一些人之前认为它可能是个复活节彩蛋。 再次编辑: 在API21它改为判断是否存在有包“com.coffeestainstudios.goatsimulator”的已安装app。
/**
* Used to determine whether the user making this call is subject to
* teleportations.
*
* <p>As of {@link android.os.Build.VERSION_CODES#LOLLIPOP}, this method can
* now automatically identify goats using advanced goat recognition technology.</p>
*
* @return Returns true if the user making this call is a goat.
 */
public boolean isUserAGoat() {
    return mContext.getPackageManager()
            .isPackageAvailable("com.coffeestainstudios.goatsimulator");
}
