What Is Anr Dialog In Android?

I want to know about ANR dialog in android applications and when it will happen and how to remove that. Please help me.

Solution 1:

ANR - application not responding.

This dialog appears when the main thread of the application is blocked for too long, for example, when you sleep on this thread, or performing a long connection.

Avoiding it is done by moving the heavy operations to other threads. There's a great article regarding the ways to implement that - Painless Threading.

Solution 2:

It will happen when you spend too much time on the main application thread. To avoid ANR errors, ensure any long-running work occurs on a background thread.
