What could be causing an ANR on setText on a TextView?-CodePudding

Now that Firebase has ANR reports, I'm seeing some ANRs that I never saw on the Play Store Console. I'm struggling to understand what I'm doing wrong on some of those situations, for example, I have this one ANR when calling setText on a TextView. How do I go about figuring out the issue? Is it maybe that that the text is too long or something?

Sometimes it's better you don't as you'll be wasting a lot of time figuring out what excactly is happening on that one device. Sometimes it seems to be a too low display resolution, Sometimes it's just the custom operating system of the device itself. To me, this seems more a problem with the android device, than your app itself.

look at this article. maybe you initialized your TextView with the wrong context: Difference between getContext() , getApplicationContext() , getBaseContext() and "this"
