startPreview failed

[Filipe Batista]

Hi, 

I was testing appunta by doing a simple test app based on the sample that you have, but i always get ar error 

 java.lang.RuntimeException: startPreview failed

at android.hardware.Camera.startPreview(Native Method)

I have the the camera permissions on the AndroidManifest.xml

Thanks

Best Regards

Hi Filipe

What Android version are you using in your project?

The CameraView provided only works on Android >=10.

That's because the support for turning the camera in previous versions was really and issue. If you need to compile for older versions, my advice is create your own CameraView without rotation enabled.

The phone is an LG p500.

The  interesting thing is that i have now installed the version that you have in Google Play and it works but the camera image is rotated 90º anti-clockwise. I think this problem of the camera rotation is a problem of the phone because in Wikitude i have the same problem.

The version in Google Play is the same that is in the sample folder?

Thanks

HI

Both apps are the same, but probably different versions. The version in the market is not so updated.

Could you send me the error log? I'll check and let you know, but the camera is a real hell due to incompatibilities.

There is some discussion on the camera list. Maybe you should check this:

http://code.google.com/p/appunta/issues/detail?id=2 

The problem is that pre2.3 versions have very lousy implementations of the camera rotation. My conclusion is that you can't ensure correct rotation for these versions.

I'll vote for making a non-rotable component for pre2.3 and a rotable one for later versions.
