How to Fix 'com.android.build.transform.api.TransformException' During Google Sign-In Integration?

"com.android.build.transform.api.TransformException" Issue with Google Sign In Integration

Problem:

While integrating Google Sign In into an Android app, an error occurs during build execution, leading to the following message:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.transform.api.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:Program FilesJavajdk1.8.0binjava.exe'' finished with non-zero exit value 2

Solution:

To resolve the issue, add multiDexEnabled true to the app's build.gradle file under the defaultConfig block.

defaultConfig {
    multiDexEnabled true
}

Alternatively, you can try splitting the code base into smaller modules, as suggested by Steve in another response. If the issue persists or occurs frequently, multiple Dex files (using multiDexEnabled) may help.
