I. Pre-analysis preparatory work
1. View Memory

#adb Shell

#cat/proc/meminfo

2. View process information, real-time display of resource usage for each process in the system, similar to the Task manager for Windows

#top-N 1-d 1-m 30-t

3. The virtual memory of the view, is still not understand

#cat/proc/vmstat

4. Virtual machine information, including process, thread tracking information, which is a good place to track process and thread-specific points.
Export to current directory adb pull/data/anr/traces.txt.

Second, analysis log
1. Find keywords
By looking for: "Null", "Error" "" "" e/"," Fatal "," NullPointerException "," Build Fingerprint: "," Exception "," ANR "," dexopt ", and so on, To locate the problem

1) NULL pointer problem
NullPointerException: This directly find the Java code, first analyze why it is a null pointer, if there is no logical problem, plus a judgment can be, that is, if the empty time to assign a value or directly return

2). No catch exception problem
Exception: Captures the words to capture

3) ANR Problem
ANR: To analyze the cause, see what's causing it, and then optimize the code
