| == Introduction ==
| | Note: Open-Xchange is in the process of migrating all its technical documentation to a new and improved documentation system (documentation.open-xchange.com). Please note as the migration takes place more information will be available on the new system and less on this system. Thank you for your understanding during this period of transition. |
| | |
| For Appsuite UI development, it is important to determine whether the code is running on a mobile device or not. Furthermore, a solid distinction between smartphones and tablets is important. Since the development of 7 inch tablets, the device detection is more complicated. Therefore, we use a list of the 125 most used devices to verify our classification procedure.
| |
| | |
| == Detection criteria ==
| |
| | |
| A device is classified as a smartphone, if
| |
| * it has the correct size (smallest dimension <= 540),
| |
| * touch input and
| |
| * a mobile OS (iOS or Android)
| |
| | |
| === Device size ===
| |
| | |
| In a mobile browser, we have access to the css pixels of the screen in the variables <tt>screen.width</tt> and <tt>screen.height</tt>. It turned out, that 99% of smartphones can be distinguished from tablets because one dimension of a smartphone has less than 540 pixels.
| |
| | |
| We figured out that in the android stock browser these variables contain the actual physical pixels of the device. Therefore, the <tt>window.devicePixelRatio</tt> is used as divider for the screen dimensions.
| |
| | |
| === Touch and Mobile OS ===
| |
| | |
| To ensure, that a browser on a desktop pc which is scaled to a small size is not detected as a smartphone, we check if the device has touch input and is running a mobile operating system like android, ios, blackberry or windows phone. Furthermore, there are some small desktop screens with touch input which can only be detected using its operating system and/or if it uses touch input.
| |
| | |
| === Custom Detection ===
| |
| | |
| There are two devices in our list which are not detected correctly. At first, the Kindle Fire HD 7 inch. But Kindle is not supported by the Appsuite. Thus, it can be neglected. The second device is the Motorola Droid Razr HD. This device has a resolution of 1280 * 720 and a css pixel ratio of 1. That is why the size test will fail and we detect this device as a special case.
| |
| | |
| == Device list ==
| |
| | |
| The following list shows all devices, we used to verify our classification. In this list the device width and height is in CSS pixels.
