Unlike the current high-end devices (WII, Xbox 360 and PS3), mobile devices are very limited on the market and all mobile devices are different. Like Adroid mobile phones, because the brand and the factory years of different, a part of the mobile phone relative to the entire market is old, slower.

Pause Game Overview:
When the game is in progress, the player may encounter a variety of unexpected events. In the cool game of sudden situation of the impact of the game more, the game is played when the player died, the game can only start from scratch, so if the external factors affecting the game, it is obviously unreasonable. Developers change according to this demand, no game added pause function. Next we'll learn how to implement the Pause function in

The physical deletion is actually deleted, and the tombstone retains the location of the data in the database, but modifies its delete flag as deleted (it looks like this is learning in college ...). ) 2, in the UI layer (user interface), if something goes wrong, or the operation fails, you should remind the user what to do next. For example: When the user takes action B, the option A must be

The Earth's revolution is one year. However, the alternating seasons are not due to changes in the Earth's distance from the sun. The earth is too far away recently for the 147,000,000km, the furthe
