Userdebug version: Partial debug version
To understand the differences between the Android compilation options Eng, user, and Userdebug, you need to understand the configuration items in the Android.mk file under Local_module_tags, and the general configuration is local_module_tags: = user Eng Optional Test this way. So what's the effect of setting Local_module_tags to different values? The following are the results of the compilation of different values: 1, User: Only in the user version of the module is compiled into; 2, Eng: Only in the Eng version of the module is compiled, 3, test: Only in the tests version of the module is compiled in; 4, Optional: All versions are compiled with this module in.
The values can be set to 1 or more, respectively, corresponding to the same or multiple compilation options. So what is the difference between Eng, user, Userdebug?
