The Android source code directory hardware/ril/libril contains a total of five C/CPP files: ril_commands.h, ril_unsol_commands.h, ril_event.h, ril_event.cpp, and ril. cpp. This article mainly analyzes the ril. cpp file.We can divide the file into the definition part and the implementation part. Let's look at the definition part first:[Cpp]# Define LOG_TAG "RILC"# Include # Include # Include # Include # Incl
