I was trying camera in android and thought of overrelay frame using surfaceview, found out this example.. Android creating camera and overrelay frame. Example was great.
1.Started enhancing so changed the potrait and landscape frames, the camera view was not showing when i change to potrait so checked and got ans from this link stackoverflow(changing display orientation), Inserted code in surface changed for that..showed error in setparameters, so deleted, it worked
2.But when i see the photo which i took it is showing like this..
Image. Then again got ans from this link ExifInterface(orientatioin)
- Front Camera is not opening too.. ??
