Supplementary knowledge: Android real machine debugging does not print log

During the development of Android, sometimes log printing is obviously performed when debugging with a real machine, but the console just does not output, which may be because the log printing function of the mobile phone is not turned on (log printing will affect the performance of the mobile phone, so the manufacturer will turn it off by default)

Solution:

1. First condition: Turn on the developer mode (for mobile phones, click several times continuously at the version number)

2. Turn on log printing
