Question

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.

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?

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

Thanks!

Try using:

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

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" />
