This solution will work forallversions of Android. You can use reflection in Java to make it work for all Android devices:
Basically you should create a reflection wrapper to call the Android 2.2 setDisplayOrientation, instead of calling the specific method.
The method:
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) { } }
And instead of usingcamera.setDisplayOrientation(x)usesetDisplayOrientation(camera, x):
if (Integer.parseInt(Build.VERSION.SDK) >= 8) setDisplayOrientation(mCamera, 90); else { if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) { p.set("orientation", "portrait"); p.set("rotation", 90); } if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) { p.set("orientation", "landscape"); p.set("rotation", 90); } }
