Android Logcat allows you to conveniently observe the debugging content, basically using the method (using Logcat to debug programs ). What is the difference between Log. v Log. d Log. I Log. w Log. e? 1. Log. the debugging color of v is black, and any message will be output. Here v stands for verbose, which is usually used as Log. v ("", ""); 2. Log. the output color of d is blue and only the meaning of debug debugging is output. However, It outputs the upper-layer information and filters it out. You can use the Logcat label of DDMS to Select Log. the output of I is green. Generally, it prompts the message information and does not output the Log. v and Log. d, but the information of I, w, and e is displayed. 4. Log. w indicates orange, which can be seen as a warning of warning. Generally, we need to optimize the Android code and select it to output logs. e. 5. If Log. e is red, you can think of error errors. Here, only red error messages are displayed. We need to carefully analyze these errors and view stack information.
