如何检查是否广播发送具有自定义权限发送 [英] How to check if a BroadCast Sender has a custom permission to send it

问题描述

我有我的应用程序正在开始广播插件。我已经成功地添加自定义权限，所以只有应用程式上的权限的用户可以接收广播。

I have a plugin for my app that is started with a BroadCast. I already managed to add a custom permission, so only apps with the permission can receive the broadcast.

不过，我不知道如何实现，更重要的部分：？我如何检查，如果发件人有一个自定义权限，所以只有我主要的应用程序可以发送广播

However, I have no idea how to achieve the more important part: How can I check, if the sender has a custom permission, so only my main app can send the broadcast?

我知道这是可能的，但我不知道该怎么做。

I know this is possible, but I don't know how to do it.

谢谢！

推荐答案

请尝试使用：

Context ctx = ...;
int result = ctx.checkCallingPermission("your.permission.goes.here");
if (PackageManager.PERMISSION_GRANTED == result) {
    // Do your stuff here
}

在您广播接收机。或声明的权限在AndroidManifest.xml中，你定义你的接收器。

in your broadcast receiver. Or declare the permission in your AndroidManifest.xml where you define your receiver.

<reciever android:name="your.receiver.goes.here"
    android:permission="your.permission.goes.here" />
