How to call the stack trace and androidstack for Android programs? You can find out the call stack trace of a program to know who called this interface, and quickly learn the call process of the program, which is very practical.

Android development, the Java layer can easily capture crashlog, but for the Native layer of crashlog is usually not directly accessible, only through the system's Logcat to analyze crash logs.Both Linux and WIN32 developers know that when the program crash on a PC, the core dump file can be generated to parse the function call stack and the memory information at the time of the crash with related tools.So,
