Specific conditions of it.
960 × 540,720 P, 1080P phone a lot ah, basically had to support. 960 * 640 In addition to the cottage Meizu and iPhone, as well as in the use Which?
Not to 2.1 must support some functions on lower versions can not be achieved.

We here in order not to increase the pressure on the server, the server DUANMU pictures conversion tool, thanks to client-side processing. If you make a resolution to support so many words, pictures how to deal with?

ios android developers did not like, except for a resolution to develop some special cases, such a program can only run on a specific resolution machine, this is too little.
Because the resolution varied, so only the relative placement sdk, frame layout, etc. In addition when the android development, set the control size, location can not be as straightforward as setting the pixel px ios, but the use of dp, dip, etc. More When the picture is to, with the effort to make the distance to other controls, such as a listview of data around the screen background and spaced from the center, can cut a wide stock of 640 bar, and then the program proceeds directly to set fill, namely lateral full screen, and then set its distance from both sides of the screen, such as setting 10dp, so you can probably fit all models.
So, android application development, making the interface is basically impossible and renderings exactly the same, this has to be the boss explained that most bosses do not understand technology, in full accordance with renderings, according to ios, if the bulkhead specializes finally mostly thankless task.
