Recently when we migrated one of our android application to AndroidX, using android studio’s option from “Refactor -> Migrate to AndroidX” , it was expected that everything should work fine but during compilation it failed with following error, AndroidRuntime: Caused by: android.view.InflateException: Binary XML file line #16: Error inflating class androidx.constraintlayout.ConstraintLayout AndroidRuntime: Caused by: java.lang.ClassNotFoundException: Didn't find class "androidx.constraintlayout.ConstraintLayout" on path Solution This error has came because android was not able to find “androidx.constraintlayout.ConstraintLayout” class after migrating to androidX, since android uses “androidx.constraintlayout.widget.ConstraintLayout” class in androidX hence search for all occurrences of “a ndroid.support.constraint.ConstraintLayout ” and change those to “ androidx.constraintlayout.widget.ConstraintLayout “

Execution & Command Syntax

Terminalbash
sed by: android
Terminalbash
sed by: java
Terminalbash
find class "androidx

Gotchas and Common Issues

  • Permission Verification - confirm execution permissions and path variables before invoking system binaries.

  • Version Compatibility - check software version release notes for deprecated flags or syntax changes.

  • Log Monitoring - inspect system logs (journalctl or /var/log) to troubleshoot execution failures.

Following these steps ensures clean configuration, proper security boundaries, and reliable execution for error inflating class androidx.constraintlayout.constraintlayout.
