Databinding cast that crashes the app?

[ghost]

Hey there,
Whenever I attempt to extend to app/IntroActivity class, i get this weird exception that seems to be casting the bindings generated for my package and the library's package? It crashes the app.

Caused by: java.lang.ClassCastException: me.morgy.fish.databinding.MiActivityIntroBindingImpl cannot be cast to com.heinrichreimersoftware.materialintro.databinding.MiActivityIntroBinding

This crash has recently started to happen with 100% reproducibility. I suspect it might be related to upgrading Gradle from 4.4 to 4.6 as recommended by the latest version of Android Studio 3.1.4 & unexpected interactions with Data Binding.

I see that work is already underway to remove the dependency on Data Binding (c60b78d), which would be awesome, because having a library add a dependency for trivial task seems like overkill.

Is there a plan to issue a new release without data binding, which would side-step this issue?

Or, if not, then is there a plan for a surgical fix to avoid these crashes for everyone using the library with the latest Android Studio + Gradle versions? Thanks!

Until this is fixed, reverting to version 1.6 seems to be an acceptable workaround. Documenting in case others find this useful!

[edotassi]

any news?

[doilio]

Same error here. any updates on how to fix this?

[ghost]

I'll leave a pr after exams, I should be able to fix this

Updating to 1.6 didn't help.
Currently running 1.5.8 looks like it did the trick.

Thanks for the library!

Wop! Having this issue in all my devices. What is actually happening?

[AnuthaDev]

I am getting exactly this error. It wwas working fine before with AS 3.1.4, Gradle 4.1, AGP 3.1.4. But today, I updated to AS 3.2, Gradle 4.6, AGP 3.2.0 and it started giving errors... Please someone fix this.

[EpsilonOrionis]

Please fix

[akashpathak]

Anyone have a work around? Downgrading to 1.5.8 did not work for me.

[Unpublished]

Updating to latest master commit (com.heinrichreimersoftware:material-intro:7221502f1f) solves it but may be unstable.

[AnuthaDev]

I downgraded to 1.6 with Gradle 4.6 and it worked for me

[doilio]

I downgraded to 1.6 with Gradle 4.6 and it worked for me

implementation 'com.heinrichreimersoftware:material-intro:1.6'
So far, It's Working for me as well. No luck with 1.6.1

[captainepoch]

With AS 3.2, Kotlin 1.2.71 and Gradle 4.6, the downgrade to the 1.6 seems to be a hack to get it working

[ferrannp]

Yeah although version 1.6.0 has more bugs than 1.6.1 (like wrong button colors on Lollipop).

[Spiderbezno]

I have the same problem since I updated to Gradle version, is there any fix?

[philbour]

This is causing my app to crash for all my users, since I updated android studio and gradle. Really need it fixed

[allato]

Updating to latest master commit (com.heinrichreimersoftware:material-intro:7221502f1f) solves it but may be unstable.

Could you TAG last commit with a new subversion to update every project?
Tnk for your job

[anisias]

I tried different options listed above and what worked for me is this combination:

• implementation 'com.heinrichreimersoftware:material-intro:1.6.2'
• classpath 'com.android.tools.build:gradle:3.2.1'
• Gradle 4.4

[simonesessa]

Works with gradle 4,4 and 'com.android.tools.build:gradle:3.1.0'.
Is there a fix for gradle 4.6?

[Aym9n]

Same here
Downgraded library to 1.6 with Gradle 4.6 and it worked.
any fixes for 1.6.2?

[msahil432]

Using 1.6, solved my issue.
I am using AS 3.3 and com.android.tools.build:gradle:3.3.0
