Gradle 2.3.0-alpha1 Data Binding Issues
Introduction
This article addresses the issue of data binding not working with Gradle 2.3.0-alpha1. This version introduced changes that resulted in data binding functionality breaking.
Root Cause
The primary culprit behind this issue is the change in the way Gradle handles dependencies. In 2.3.0-alpha1, Gradle’s dependency management was revamped, leading to conflicts with the data binding library.
Troubleshooting Steps
Here’s a breakdown of how to resolve the data binding issue with Gradle 2.3.0-alpha1:
1. Dependency Configuration
* Ensure you have the correct data binding dependencies in your `build.gradle` file.
* Include the following in your dependencies block:
“`
compile “com.android.databinding:databinding-compiler:$androidDataBindingVersion”
“`
* Verify the `androidDataBindingVersion` matches your Android Gradle plugin version.
2. Gradle Plugin Compatibility
* The data binding library relies on a compatible Android Gradle plugin version.
* Ensure you are using a version that is compatible with data binding.
* Check the documentation for compatibility information.
3. Module Dependencies
* If your project has multiple modules, check that the data binding library is included in all necessary modules.
* In the module’s `build.gradle` file, add the following to your dependencies block:
“`
compile “com.android.databinding:databinding-compiler:$androidDataBindingVersion”
“`
