Java Android UserManager.isUserAGoat() 的正确用例

发布于11月14日

我在看Android 4.2年推出的新API.

public boolean isUserAGoat()
用于确定进行此呼叫的用户是否受传送的影响.

返回进行此调用的用户是否为山羊.

该如何以及何时使用？

推荐答案

Android R更新:

在Android R中，此方法总是返回false.谷歌表示，这样做是"为了保护山羊的隐私":

/**
 * 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>
 *
 * <p>As of {@link android.os.Build.VERSION_CODES#R}, this method always returns
 * {@code false} in order to protect goat privacy.</p>
 *
 * @return Returns whether the user making this call is a goat.
 */
public boolean isUserAGoat() {
    if (mContext.getApplicationInfo().targetSdkVersion >= Build.VERSION_CODES.R) {
        return false;
    }
    return mContext.getPackageManager()
            .isPackageAvailable("com.coffeestainstudios.goatsimulator");
}

先前的答案:

从100开始，该方法用于返回false，直到它在API 21中被更改.

/**
 * 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;
}

看起来这个方法对我们这些开发者来说没有实际的用处.之前有人说可能是100.

在API 21中，该实现被更改为判断是否安装了带有软件包com.coffeestainstudios.goatsimulator的应用程序

/**
 * 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");
}

这是source和change.
