Material Android Components are crashing in debug mode

[Arunachalamkalimuthu]

Description: I didn't make any changes to my code.

This issue is reproducing for both 4.1.1 and 4.4.0 Gradle versions

App crashing in debug mode but working fine in Release mode.

I tried reinstalling the android studio Nothing helps me

Android API version: Android API version Android 11 (30 )

Material Library version: com.google.android.material:material:1.2.1

Device: Pixel 3a

[wcshi]

Could you please share a stacktrace or any information about the crash?

Does the 1.2.1 lib not crash if you switch to an older Gradle version?

[Arunachalamkalimuthu]

Please check the logs

[wcshi]

Can you reproduce the app in a sample app and share with us?

[Arunachalamkalimuthu]

@wcshi Very hard to reproduce

[Arunachalamkalimuthu]

In a big project When we switch from one branch to another ..This issue is happening..

Very time I will do sync with Gradle files and invalidate the cache

Out 1/5 times it will work

[drchen]

Is this still an issue?

[mwshubham]

This is still happening on latest enviroment.

[drchen]

@mwshubham can you paste your stack trace? Is it the same crash?

[mwshubham]

This is mostly happening in Dialogs. This is happening randomly so there are no steps to reproduce it. Although, the clean rebuild is fixing this.

[drchen]

Cool thanks for the info. I'll take a look.

[drchen]

Hi I checked the relevant code - if a clean rebuild can fix the issue, it doesn't seem like something we are able to solve in the library. (The possible causes I can think of should crash both release and debug builds.)

I'll close the issue for now since it doesn't affect release and can be solved. : )
