Android camera setDisplayOrientation: weird behavior for galaxy tab

Question

I had a problem trying to view the camera in portrait mode. I read various articles about this, and I decided that it has the following code:

Display display = ((CaptureActivity)context).getWindowManager().getDefaultDisplay(); int width = display.getWidth(); int height = display.getHeight(); if (Integer.parseInt(Build.VERSION.SDK) >= 8) { setDisplayOrientation(camera, 90); }else{ Camera.Parameters parameters = camera.getParameters(); parameters.set("orientation", "portrait"); camera.setParameters(parameters); } 

where setDisplayOrientation () is defined as:

 protected void setDisplayOrientation(Camera camera, int angle) { Method downPolymorphic; try { downPolymorphic = camera.getClass().getMethod( "setDisplayOrientation", new Class[] { int.class }); if (downPolymorphic != null) downPolymorphic.invoke(camera, new Object[] { angle }); } catch (Exception e1) { } } 

Now I tried this code on the Galaxy tab and it failed. I solved this (attempt and error approach) using the following code:

 if (height == 1024 && width == 600) { Camera.Parameters parameters = camera.getParameters(); parameters.set("orientation", "portrait"); parameters.setRotation(90); camera.setParameters(parameters); } 

Now my two questions:

1) Why is there such a problem, while the Galaxy tab has version 2.2, and

2) Is there a better solution to this problem?

Thanks so much for your time!

Answer 1

to set the display orientation, check the official docs , not just 90 degrees.
