为什么玩-服务定位所需要的android.permission.WRITE_EXTERNAL_STORAG​​E和android.permission.READ_EXTERNAL_STORAG​​E权限？ [英] Why does play-services-location need the android.permission.WRITE_EXTERNAL_STORAGE and android.permission.READ_EXTERNAL_STORAGE permissions?

问题描述

我只有在AndroidManifest.xml中是：

All I have in AndroidManifest.xml is:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

上传APK给开发者控制台后，它增加了两个新的权限：

After uploading the APK to the developer console, it adds two new permissions:

我的build.gradle：

My build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "net.perspiratron.ifpaprofile"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 3
        versionName "1.2"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
//    wearApp project(':wear')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.google.android.gms:play-services-analytics:7.5.0'
    compile 'com.google.android.gms:play-services-location:7.5.0'
    compile 'com.jjoe64:graphview:4.0.0'
}

这是我加入的唯一的事情就是播放服务定位。为什么这个库需要它吗？

The only thing that I added was play-services-location. Why does this library need it?

推荐答案

简短的回答：我不相信播放服务，位置确实需要这些权限。它也不似乎需要 android.permission.ACCESS_NETWORK_STATE 或 android.permission.INTERNET对，它也正在增加。

Short answer: I don't believe play-services-location does need those permissions. Neither does it seem to need android.permission.ACCESS_NETWORK_STATE or android.permission.INTERNET, which are also being added.

更长的答案： 看着我的清单合并的日志，似乎所有这四个权限都被包括在播放服务，地图的请求，这-location是连接在它自己的协议。我的应用程序没有使用-maps，只是-location。

Longer answer: Looking at my manifest merger log, it appears that all four of these permissions are being included at the request of play-services-maps, which -location is linking in of its own accord. My app isn't using -maps, just -location.

另外，我发现，这种现象只是出现在播放服务定位7.5.0版本;之前的版本不包括-maps，并且不添加这些权限。

Further, I've found that this behavior just appeared in version 7.5.0 of play-services-location; prior versions didn't include -maps, and don't add those permissions.

其实，我怀疑这方面发挥-服务，地图是偶然的，并会在大湄公河次区域的未来版本中删除。

I actually suspect that this connection to play-services-maps is accidental, and will be removed in a future release of GMS.

由马克·墨菲（CommonsWare）给出的链接之后，你可以通过添加如下行到你的清单中，从你的应用程序中删除这些权限：

Following up on the link given by Mark Murphy (CommonsWare), you can remove these permissions from your app by adding the following lines to your manifest:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" tools:node="remove" />
<uses-permission android:name="android.permission.INTERNET" tools:node="remove" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" tools:node="remove" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="remove" />

请注意，您还需要的xmlns：工具=htt​​p://schemas.android.com/tool​​s在打开的＆LT ;清单...＆GT; 元素，使这些工作。和平常的警告适用于：我的应用程序精细的工作采取这一步骤之后，但情况因人而异

Note that you'll also need xmlns:tools="http://schemas.android.com/tools" in your opening <manifest ... > element to make these work. And the usual caveats apply: my app worked fine after taking this step, but YMMV.

更新2015年9月10号：马克·墨菲（@commonsware）做的一个优秀的书面记录就在他的博客这个问题，包括我的解决方案的风险进行了讨论。

Update 10 Sep 2015: Mark Murphy (@commonsware) has done an excellent writeup on this issue on his blog, including a discussion of the risks of my solution.
