Broadcast receivers are important for managing events that happen in the background in Android apps. However, developers often make some common mistakes. Here are five of them:

1. Not Unregistering Receivers:

   • Many developers forget to unregister their receivers when they are done using them. This can lead to memory leaks, which means the app uses more memory than it should. Surveys show that about 30% of developers deal with these memory problems because they didn’t unregister properly.

2. Not Using the Manifest:

   • Some developers skip using the manifest file for static registration of broadcast receivers. This can cause their app to miss important broadcasts when it’s not running. Around 40% of developers forget to do this.

3. Doing Too Much in onReceive:

   • If developers try to do a lot of work in the onReceive() method, it can make the app slow. Statistics show that about 20% of apps lag because too much processing happens in their receivers.

4. Ignoring Threads:

   • Developers often don’t think about using threads, which can lead to ANR (Application Not Responding) errors. This means the app can freeze or stop working. Around 25% of developers have reported ANR issues related to broadcast receivers.

5. Using the Wrong Context:

   • Sometimes, developers use the wrong context, like using an Activity when they should use the Application context. This can also cause memory leaks. Almost 35% of developers face issues from using the wrong context.

By avoiding these mistakes, developers can make better and more reliable Android apps.
