Get rid of "Exported service does not require permission" warning
提问by rekire
I'm looking for a solution to get rid of the warning. I don't understand even why it appears. I took a look at a SDK example where no warning appears.
我正在寻找消除警告的解决方案。我什至不明白它为什么会出现。我查看了一个没有出现警告的 SDK 示例。
At first here is my manifest where I get the warning Exported service does not require permission:
首先，这是我的清单，我收到警告导出服务不需要许可：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-feature android:name="android.hardware.camera"
android:required="true" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
<uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_SYNC_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.Sherlock">
<service
android:name=".AuthenticationService"
android:exported="true">
<intent-filter>
<action
android:name="android.accounts.AccountAuthenticator" />
</intent-filter>
<meta-data
android:name="android.accounts.AccountAuthenticator"
android:resource="@xml/authenticator" />
</service>
<activity
android:name=".Test"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
...
While the SampleSyncAdapterof the Android SDK has this manifest:
虽然Android SDK的SampleSyncAdapter有这个清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.samplesync"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
<!-- ... -->
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />
<application
android:icon="@drawable/icon"
android:label="@string/label">
<!-- The authenticator service -->
<service
android:name=".authenticator.AuthenticationService"
android:exported="true">
<intent-filter>
<action
android:name="android.accounts.AccountAuthenticator" />
</intent-filter>
<meta-data
android:name="android.accounts.AccountAuthenticator"
android:resource="@xml/authenticator" />
</service>
...
But there is no warning. Why the hell do I get a warning? Well I use the Theme.Sherlock theme for the usage of the ActionBarSherlock. But I cannot imagine that this causes the error.
但是没有警告。为什么我会收到警告？好吧，我使用 Theme.Sherlock 主题来使用ActionBarSherlock。但我无法想象这会导致错误。

The warning is telling you that you have exported (ie: made publicly available) a service without securing it with a permission. This makes your service available to any other applications without restrictions. See Exported service does not require permission: what does it mean?
该警告告诉您，您在未经许可保护的情况下导出（即：公开提供）服务。这使您的服务可无限制地用于任何其他应用程序。请参阅导出的服务不需要许可：这是什么意思？
If your service doesn't need to be available to other applications, you don't need to export it. Explicitly setting android:exported="false"will remove the warning.
如果您的服务不需要对其他应用程序可用，则不需要导出它。显式设置android:exported="false"将删除警告。
Note:The default value for android:exportedis trueif you have provided an Intent filter.
注意：默认值android:exported是true如果您提供了意图过滤器。

You need to add a permission requirement for your service. The one you need is android.permission.ACCOUNT_MANAGER. Your authenticator is only accessed through the manager.
您需要为您的服务添加权限要求。你需要的是android.permission.ACCOUNT_MANAGER. 您的身份验证器只能通过管理器访问。

Regarding this issue, there is already a bug created in Android project about this warning using "Sync Adapter": https://code.google.com/p/android/issues/detail?id=37280but it's still an Open bug.
关于这个问题，Android 项目中已经使用“同步适配器”创建了一个关于此警告的错误：https: //code.google.com/p/android/issues/detail?id=37280但它仍然是一个开放错误。
