Android Bad Practices: Missing Component Permission

Java/JSP

Abstract

程序未为此公共组件明确分配访问权限。

Explanation

任何应用程序都可以访问在清单定义中未明确分配访问权限的公共组件。

Android 应用程序中活动、接收者和服务组件的 exported 属性的默认值取决于是否存在 intent-filter。如果存在 intent-filter，则说明该组件供外部使用。因此应将 exported 属性设为 true。现在，Android 平台上的任何其他应用程序都可以访问该组件。

示例 1：以下是一个 Android 活动示例，该示例存在 intent-filter 且未设置明确访问权限。

 <activity android:name=".AndroidActivity"/>

   <intent-filter android:label="activityName"/>

    <action android:name=".someFunAction"/>

   </intent-filter>

...

 </activity>

此活动可能遭到恶意应用程序利用。
