Re: [android-developers] Re: Android camera orientation problem
Haris, take a look a this: http://developer.android.com/reference/android/hardware/Camera.html#setDisplayOrientation(int) This is for API 8 (2.2+) devices. I've found that there's no reliable way to guarantee this to work on 2.1 devices by setting the camera parameters the way you are now, some just won't do it. I've just spent quite a bit of my spare time working on implementing a portrait mode activity option for the camera preview - to answer Spooky's question, the main reason one might do this is because it goes well with the UI/UX of the application (specifically the other activities which share a common UI), and the application for the camera activity is augmented reality, and for most devices that I've had experience with, the sensors seem to be most accurate when the phone is held in portrait - though this can clearly vary. It also was desired to have a working portrait mode version of the camera activity, instead of forcing the user to then change the way they were holding the device. Instagram is one massively popular application which does this as well (or at least, appears to do so), and I think it works well with their UI. You can of course, take advantage of the above method to simply rotate the preview depending on the current orientation of the device - either portrait or landscape, and indeed have different UIs for either scenario if you wish. Of course then choosing the optimal preview size for your orientation, taking into account status bars or full screen, etc, can then be tricky and yield different results for each. The default camera app seems to rotate it's UI elements which is a pretty neat solution. Rotating any preview frames or shots is the least of the worries here, that's relatively simple to do.

Re: [android-developers] Re: Android camera orientation problem
Haris, check the link I provided, this is code you can call which will make the camera orientation the same as the activity orientation. for instance if you set the activity orientation to portrait, calling the method will also rotate the camera preview -- http://developer.android.com/**reference/android/hardware/**Camera.html#** setDisplayOrientation(int)http://developer.android.com/reference/android/hardware/Camera.html#setDisplayOrientation(int) they provide some code here. Note that any preview frames will not be rotate, though. If you want to make the camera image show in the same orientation as the display, you can use the following code. public static void setCameraDisplayOrientation(Activity activity, int cameraId, android.hardware.Camera camera) { android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo(); android.hardware.Camera.getCameraInfo(cameraId, info); int rotation = activity.getWindowManager().getDefaultDisplay() .getRotation(); int degrees = 0; switch (rotation) { case Surface.ROTATION_0: degrees = 0; break; case Surface.ROTATION_90: degrees = 90; break; case Surface.ROTATION_180: degrees = 180; break; case Surface.ROTATION_270: degrees = 270; break; } int result; if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) { result = (info.orientation + degrees) % 360; result = (360 - result) % 360; // compensate the mirror } else { // back-facing result = (info.orientation - degrees + 360) % 360; } camera.setDisplayOrientation(result); } On Wed, Oct 24, 2012 at 1:46 AM, Haris haris...@gmail.com wrote: Hi thanks all for your replays..
