Thanks.

The error is quite explicit: android.content.ActivityNotFoundException: Unable to find explicit activity class {jp.co.sharp.android.camera/jp.co.sharp.android.camera.videocamera.VideoCamera}; have you declared this activity in your AndroidManifest.xml?

Make sure you have that activity in your manifest
