Unified management of Android development logs and unified management of android

Unified management of Android development logs and unified management of android

During development, we usually need to manage the log output in a unified manner. Below we recommend a log output class. In the development stage, we only need to set the DEBUG constant to true, set DEBUG to false in the production environment to control log output. If you don't want to talk about anything, you need to take it directly.
