java.lang.IllegalStateException: Session has been closed; further changes are illegal.

When calling cameraView.start(); I get the following exception:

java.lang.IllegalStateException: Session has been closed; further changes are illegal. at android.hardware.camera2.impl.CameraCaptureSessionImpl.checkNotClosed(CameraCaptureSessionImpl.java:606) at android.hardware.camera2.impl.CameraCaptureSessionImpl.setRepeatingRequest(CameraCaptureSessionImpl.java:227) at com.google.android.cameraview.Camera2$3.onConfigured(Camera2.java:132) at java.lang.reflect.Method.invoke(Native Method) at android.hardware.camera2.dispatch.InvokeDispatcher.dispatch(InvokeDispatcher.java:39) at android.hardware.camera2.dispatch.HandlerDispatcher$1.run(HandlerDispatcher.java:65) at android.os.Handler.handleCallback(Handler.java:751) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6077) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:865) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:755)

Note: I’m not calling it in onResume. Rather after the Camera permisison has been granted.

It seems like this was occurring for me when I setVisibility(VISIBLE) and then immediately attempted to start() the CameraView. My workaround: do the visibility change and post the start() to allow it time for the view to be ready.

view_main_camera.setVisibility(VISIBLE);
view_main_camera.post(new Runnable() {
  @Override
  public void run() {
    view_main_camera.start();
  }
});

Seems to work!
