使用-权限VS用途特征 [英] Uses-Permission vs Uses-Feature

问题描述

我见过的人，要求和人民解释两者的区别许多具体情况，但我不能，似乎不明白一般的差别。是两个同义？另做一件意味着什么呢？

解决方案

  

是两个代名词？

没有。 ＆LT;使用许可权＆GT; 说：哎，机器人（以及相关的分销渠道），请向用户允许我做X。 ＆LT;使用特征方式＆gt; 说：哎，机器人（以及相关的分销渠道），我感兴趣的是与特征量y的硬件上运行

＆LT;使用特征＆GT; 可以过滤你从Play商店（和其他渠道），如果硬件不能满足您的要求，但用户没有按'吨得到参与。

  

做一件意味着其他？

有时。 如果您要求某些权限，如 CAMERA ，Android的假设默认情况下，你需要相应的硬件。您可以使用＆LT;使用特征＆GT; 和的android：要求=假，如果来覆盖默认行为，必要的。

I've seen many specific cases of people asking and people explaining the difference between the two but I can't and don't seem to understand the general difference. Are the two synonymous? Does one imply the other?

解决方案

Are the two synonymous?

No. <uses-permission> says "hey, Android (and associated distribution channels), please ask the user to allow me to do X". <uses-feature> says "hey, Android (and associated distribution channels), I am interested in running on hardware with feature Y".

<uses-feature> may filter you out of the Play Store (and other channels), if the hardware does not meet your requirements, but the user doesn't get involved.

Does one imply the other?

Sometimes. If you request certain permissions, like CAMERA, Android assumes by default that you need the corresponding hardware. You can use <uses-feature> and android:required="false" to override that default behavior, if needed.
