Question

Hi there It seems like there is little to none information about the fact that android recreates the activity when an exception is thrown inside a ViewModel class instead of just crashing the app Upon doing so some of my app resources are left in an inconsistent state I would rather let it crash instead Can anyone help me with some information in this regard

I don t think that is Android ViewModel behavior but you might see that if you have Crashlytics Fabric or other crash reporting tools installed

I created a simple app to reproduce the behavior throwing the exception on button click from Activity gt crashed the app but doing so from the ViewModel recreates the activity first and the second time crashes the app

How would that even work It s not that all the calls in view model are magically wrapped in try catch thinking face

this only happens if you use `FLAG ACTIVITY NEW TASK` iirc

Doru N. · Answer

< zhuinden> Indeed there seems to be something related to starting a new activity when reproducing this issue yet I do not still understand why as I am starting the new Activity using the simple ```startActivity Intent this MainActivity class java ```

Doru N. · Answer

I do not set a `FLAG ACTIVITY NEW TASK` anywhere niether Manifest nor directly on Intent starting this new Activity

Also crashing inside the Activity always displays the Crash popup and closes the app but doing so inside the ViewModel lt sometimes gt it just eats the crash and closes current Activity displaying the previous screen as if nothing bad happened

Doru N. · Answer

I kept on testing and I discovered that the crash does not have to be inside the ViewModel it can be reproduced in an Activity also but first time only crashing a second time will display the dialog Is this a native behavior my test project has `compileSdk` amp `targetSdk` set to `28`

wasyl · Answer

gt lt sometimes gt it just eats the crash and closes current Activity displaying the previous screen as if nothing bad happened not all crashes are shown as dialogs

wasyl · Answer

In developer options there s `always show crash dialog` option Iirc at some point Android stopped showing each crash since the user can sometimes even miss that the app has crashed it just seems like recreating the activity
