Make Android logs more useful

Address: http://marspring.mobi/android-log/

Android logs differ from those of Java EE such as log4j. For example, you cannot simply set the log to be printed by level, or print the information of the class that calls the log in the log, method Name, row number, and so on. Stacktraceelement is used to encapsulate the android log class. You can print the class in which the current log is located, the method name called, and the row number.
