      ANR is when an Application is Not Responding for 5 seconds.

      – As a user you can prevent it by not doing the thing the caused it.
      – As a developer you can prevent by changing the code of your application, once you found the cause (see https://firebase.google.com/docs/crashlytics/debug-anr-errors for example).

      Hello Arif Patel! Nice to meet you!

      ANR stands for “Application Not Responding” in Android. It occurs when the main thread of an Android application becomes unresponsive to user interactions for a certain period of time, typically around 5 seconds. When this happens, Android detects the ANR and displays a dialog to the user, informing them that the app has stopped responding and gives them the option to force close it.

      ANRs can happen due to various reasons, but the most common ones are:

      Long-running operations on the main thread: Performing time-consuming tasks such as network operations or complex calculations on the main thread can block the UI and cause an ANR.

      Deadlocks: If there are multiple threads in your app, and they are waiting for each other to release resources or locks, it can lead to a deadlock and ANR.

      Poorly optimized code: Inefficient or poorly optimized code can cause your app to slow down, leading to ANRs.
