How can I display a dialog from the receiver for Android broadcasting?

Question

Ideally, I do not want to start work to do this. When the Wi-Fi connection is lost, my application needs to close, because this is a fatal error for us. I want to show an error message and click Ok, and then exit the application. What is the best way to do this?

Thanks!

AFAIK, only actions can display dialogs. If yes, and if your BroadcastReceiver registered through an action through registerReceiver() , you are configured - just use this activity. If, however, your BroadcastReceiver registered in the manifest, I think you will have no choice but to do something else.

For example, you can send an ordered broadcast of Intent . In your current action - if any - BroadcastReceiver will take precedence for this Intent , and then a dialog may appear when it receives the broadcast. If, however, none of your actions are displayed on the screen, you could register a low priority BroadcastReceiver with confirmed BroadcastReceiver manifests if you want to display Notification or something else. Here is a blog post that covers a bit more about this template.
