Create an Android startup Interface

After each Android application is started, a Splash startup interface is displayed, showing the product LOGO, company LOGO, or developer information. If the application starts for a long time, the startup interface is a good thing, so that users can wait for this boring time.

• Create a Splash Interface
  Highlight the product LOGO, product name, and main features;
  Indicates the product version information;
  Indicate company or developer information;
  The background image can also be replaced by the background color;

• What can I do besides waiting?
  Most Splash interfaces wait for a certain period of time and then switch to the next interface;
  In fact, during this period, you can check the system status, such as whether the network is connected and whether the power supply is sufficient;
  Or, pre-load the relevant data;
  To make the startup interface display time fixed, you need to calculate the time required to execute the preceding preprocessing tasks. The time required to start the interface SLEEP = fixed time-the time required to start the preprocessing task.
• Source code example (take the Android client of Wordpress as an example)
