Android: OnBootReceiver: Exported receiver does not require permission
提问by Xander
I've created a BroadcastReceiver, which receives BOOT_COMPLETED.
我创建了一个BroadcastReceiver，它接收BOOT_COMPLETED.
In my AndroidManifest.xmlI've added it like so:
在我的AndroidManifest.xml我已经添加它像这样：
<receiver
android:name=".OnBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
However, I get the warning: Exported receiver does not require permission.I've read about it on SO, but I don't fully understand it.
但是，我收到警告：导出的接收器不需要许可。我已经在 SO 上阅读过它，但我并不完全理解它。
So could someone explain to this beginner :) why I'm getting this warning, and what to do against it (and why)?
所以有人可以向这个初学者解释 :) 为什么我收到这个警告，以及如何处理它（以及为什么）？

The warning
警告
Exported receiver does not require permission
导出的接收器不需要许可
means,
You have an intent-filter with some action (which means by default you have android:exported="true"set and it can now receive broadcasts from ANYbroadcasters outside of your application)
Since it can receive broadcasts from ANYbroadcasters outside of your application, it warns you by saying "Hey, are you sure ANYbroadcaster can invoke you? In my opinion, it is better if you allow only those broadcasters to invoke you that has the permission you have set for this receiver through android:permission"
意味着，您有一个带有某些操作的意图过滤器（这意味着默认情况下您已经android:exported="true"设置并且它现在可以从您的应用程序之外的任何广播公司接收广播）由于它可以从您的应用程序之外的任何广播公司接收广播，它会通过以下方式警告您说“嘿，你确定任何广播公司都可以调用你吗？在我看来，如果你只允许那些广播公司通过android:permission为这个接收器设置权限来调用你会更好”
Hope this is clear!!!
希望这很清楚！！！
