From: http://blog.csdn.net/netpirate/article/details/5351709

The debugging procedure is as follows:
1. Save the abnormal address information to a text file and store it in the project root directory;
2. Use panic. py to parse the file;
3/debug Based on the returned information (file name; row number; method name)Program.

Take the touch input Input Method of a third party as an example. The process is as follows:

# The English and handwriting of the input method are OK. When you operate the Chinese input method, an exception occurs and the keyboard disappears. The exception log is as follows:
