Android app crashes with IllegalViewOperationException: Trying to add unknown view tag


Hi Expo team,

I’m encountering an issue with Android standalone apps only, crashing with the error log below. A very similar issue has been referenced a few times on github (
and However, I am on SDK v24 and still getting the bug across a variety of Android versions and device types. We are also not using LayoutAnimation (was suggested as a potential culprit).

@jesse mentioned a fix with this that went out with SDK v23 so I’m curious if you have a take here on what could be causing it? Thanks again for all the help! Trying to add unknown view tag: 1210
detail: View tag:1213
