The android-check workflow was failing at :app:lintDebug due to an invalid MotionLayout scene reference in fragment_login.xml. Lint reported MotionLayoutInvalidSceneFileReference because app:layoutDescription was set to @null.

• Root cause

  • app/src/main/res/layout/fragment_login.xml used app:layoutDescription="@null" on a MotionLayout, which is rejected by Android lint.

• Code changes

  • Updated login layout to reference a real scene file: @xml/scene_login.
  • Added app/src/main/res/xml/scene_login.xml with a valid MotionScene (start/end constraint sets + transition) for login_motion_layout, matching existing motion behavior patterns used elsewhere in the app.

• Representative diff

  <!-- fragment_login.xml -->
  - app:layoutDescription="@null"
  + app:layoutDescription="@xml/scene_login"

  <!-- scene_login.xml -->
  <MotionScene ...>
      <Transition
          app:constraintSetStart="@+id/start"
          app:constraintSetEnd="@+id/end" />
      ...
  </MotionScene>
