Android Camera Error 5001

Question

I just had a Camera "Error 5001" error while loading a Camera object on my Android app.

E/Camera: Error 5001

I cannot even exit the application with the "home" button, it freezes for 90 seconds. I can't find any documentation regarding that error.

What does 5001 mean?

After 90 seconds, the logcat logs:

W/CameraBase: Camera service died!

Now I can't run the app normally. The screen is green and fails to load the camera.

A reboot fixed that Camera issue, but I would like to know:

• what actually happened
• how to avoid it

The device is a Moto X with stock Android 4.4.2.

Thank you for any information.

Answer 1

As I pointed out, this error seems to only occurs on the Moto X and seems to be specific to some use-cases.

It just happens from time to time on this device running Android 4.4.2.

To me, it's just a specific/too-localized bug.

Closed.
