CameraX - I/zygote: Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>

Question

I am developing a simple app based on the CameraX Jetpack support library through the provided getting started guide and a GitHub repo. Getting the error

I/zygote: Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>:  java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener; 

when I set the layout of the sample activity (CameraActivity). Tested the sample code on both the virtual and real devices on API level 26. The version of the CameraX library is 1.0.0-alpha03 which is the latest available version.

Here is the code of my layout:

<TextureView     android:id="@+id/textureView"     android:layout_width="match_parent"     android:layout_height="match_parent"     app:layout_constraintBottom_toBottomOf="parent"     app:layout_constraintEnd_toEndOf="parent"     app:layout_constraintStart_toStartOf="parent"     app:layout_constraintTop_toTopOf="parent" />  <ImageButton     android:id="@+id/btnCapture"     android:layout_width="72dp"     android:layout_height="72dp"     android:scaleType="fitCenter"     android:layout_margin="24dp"     app:layout_constraintBottom_toBottomOf="parent"     app:layout_constraintEnd_toEndOf="parent"     app:layout_constraintStart_toStartOf="parent"     app:srcCompat="@drawable/ic_camera_accent"     android:background="?selectableItemBackgroundBorderless" /> 

Here is the code of my activity:

public class CameraActivity extends AppCompatActivity {      private TextureView textureView;     private ImageButton btnCapture;      private int REQUEST_CODE_CAMERA_WRITE_EXT = 10;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);

Solved the issue for me.

build.gradle (app level)

//Adding dependency
