Unexpected App Crashes When Using Custom View with Data Binding in Android 14
I'm stuck trying to I'm trying to configure I've been banging my head against this for hours... I'm experiencing frequent crashes in my Android 14 app when trying to implement a custom view with Data Binding. The custom view is designed to display user profiles, and I am using a ViewModel to supply the necessary data. However, when I bind the ViewModel to the custom view, I get a `ClassCastException` during runtime. Here’s a simplified version of what I’ve implemented: In my layout XML file, I have: ```xml <layout xmlns:android="http://schemas.android.com/apk/res/android"> <data> <variable name="viewModel" type="com.example.app.ProfileViewModel" /> </data> <com.example.app.CustomProfileView android:id="@+id/customProfileView" android:layout_width="match_parent" android:layout_height="wrap_content" app:profileData="@{viewModel.profileData}" /> </layout> ``` In my `CustomProfileView`, I have the following constructor: ```java public CustomProfileView(Context context, AttributeSet attrs) { super(context, attrs); init(); } private void init() { // Custom initialization code } ``` During runtime, I see the following behavior in Logcat: ``` java.lang.ClassCastException: com.example.app.ProfileData want to be cast to com.example.app.ProfileData ``` I’ve checked that the `profileData` type in my ViewModel does match the expected type in the custom view. I've also tried cleaning and rebuilding the project, but the scenario continues. I suspect it might have something to do with how the layout inflater processes the data binding expressions, especially since I’m using a dynamic layout. What am I missing? How can I resolve this ClassCastException? Any insights into how Data Binding handles custom views would be appreciated. I'm working on a CLI tool that needs to handle this. This issue appeared after updating to Java 3.9. Thanks for any help you can provide! I'm developing on Ubuntu 22.04 with Java. I'd love to hear your thoughts on this.
