我有一个Android应用程序中，我在清单中定义多个不同的活动。其中一些活动有意向的过滤器，我使用（如ACTION_PICK）。这些活动是因为意向过滤器，显示当其他应用程序请求的活动来处理ACTION_PICK。有没有一些方法，以prevent这一点，所以，我的活动，不能访问其他应用程序？我已经尝试设置的android：在我的活动远销=假，但没有采取任何行动。

I have an android app in which I define several different activities in the manifest. Some of these activities have intent-filters that I use (such as ACTION_PICK). These activities, because of the intent-filters, show up when other applications request an activity to handle an ACTION_PICK. Is there some way to prevent this, so that my activities are not accessible to other applications? I've already tried setting android:exported="false" in my activity, but that did nothing.

推荐答案

您需要： *定义权限（这仅适用于具有签名的应用程序） *定义您的应用程序使用您定义的权限 *要求准许你想保护的活动。 （注意不要需要为您的主要推出的活动）。

You need to: * define a permission (which is only available to applications having your signature) * define that your application uses your defined permission * require that permission for the activities you want protected. (Be careful to not require it for your main launch activity).

<!-- define a permission -->
<permission
    android:protectionLevel="signature"
    android:name="com.mypackage.MYPERMISSION"/>

<uses-permission android:name="com.mypackage.MYPERMISSION" />

<!-- define an activity which can only be started through internal code -->
<activity android:name="..."
          android:permission="com.mypackage.MYPERMISSION" >
    ...
</activity>
