Android开机log分析

分析开机log，一是可以理一下android启动流程，二是可以通过log定位错误，下面列举一些常见android程序发生错误时抛出的异常，查找关键字xxxException可以快速定位android层错误以及原因：

1. Java.lang.NullPointerException：

2. 空指针异常

3. java.lang.ClassNotFoundException：

4. 找不到类抛出的异常

5. java.lang.ArithmeticException：

6. 一个整数“除以零”时抛出的异常

7. java.lang.ArrayIndexOutOfBoundsException:

8. 数组越界访问以后抛出的异常

9. java.lang.IllegalArgumentException：

10.传入非法参数抛出的异常

11. java.lang.IllegalAccessException：

12.当应用程序要调用一个类，但当前的方法即没有对该类的访问权限便会出现这个异常

13. java.lang.SecturityException：

14.安全异常。由安全管理器抛出，用于指示违反安全情况的异常

15. java.lang.RuntimeException

16.运行时异常。是所有Java虚拟机正常操作期间可以被抛出的异常的父类。

17. java.lang.NumberFormatException：

18.字符串转换为数字异常：

19. java.lang.StackOverflowError：

20.堆栈溢出错误。当一个应用递归调用的层次太深而导致堆栈溢出时抛出该错误。

21. java.lang.RuntimeException

22.java.lang.OutOfMemoryError：

23. 内存不足错误。当可用内存不足以让Java虚拟机分配给一个对象时抛出该错误。

24.java.lang.IOException：

25. 输入输出异常

26.java.lang.AbstractMethodError：

27. 抽象方法错误。当应用试图调用抽象方法时抛出。

28.java.lang.ClassFormatError：

29. 类格式错误。当Java虚拟机试图从一个文件中读取Java类，而检测到该文件的内容不符合类的有效格式时抛出。

30.java.lang.InstantiationError：

31. 实例化错误。当一个应用试图通过Java的new操作符构造一个抽象类或者接口时抛出该异常.

32.java.lang.InternalError：内部错误。用于指示Java虚拟机发生了内部错误。

33. java.lang.NoSuchMethodError

34.方法不存在错误。当应用试图调用某类的某个方法，而该类的定义中没有该方法的定义时抛出该错误。

35. java.lang.VirtualMachineError

36.虚拟机错误。用于指示虚拟机被破坏或者继续执行操作所需的资源不足的情况

37. java.lang.ClassCastException

38.类造型异常。假设有类A和B（A不是B的父类或子类），O是A的实例，那么当强制将O构造为类B的实例时抛出该异常。该异常经常被称为强制类型转换异常。

39. java.lang.InterruptedException

40.被中止异常。当某个线程处于长时间的等待、休眠或其他暂停状态，而此时其他的线程通过Thread的interrupt方法终止该线程时抛出该异常。

41. java.lang.IllegalStateException

42.违法的状态异常。当在Java环境和应用尚未处于某个方法的合法调用状态，而调用了该方法时，抛出该异常。

43. java.lang.ExceptionInInitializerError

44.初始化程序错误。当执行一个类的静态初始化程序的过程中，发生了异常时抛出。静态初始化程序是指直接包含于类中的static语句段。

开机关键log分析

[html] view plain copy

1. 1. android启动第一阶段：启动android第一个进程init，通过解析init.rc脚本，生成文件系统，启动vold、media、SurfaceFlinger等Nativie服务。在这个阶段你可以看到带“Android”文字静态logo和带“android”文字的开机动画

2. [ 3.947876] init: /dev/hw_random not found

3. ========正常打印，找不到/dev/hw这个目录

4. [ 3.952580] init: cannot open '/initlogo.rle'

5. ==========正常打印，第二个开机画面的内容是由文件/initlogo.rle来指定的。

6. 如果文件/initlogo.rle不存在，或者在显示它的过程中出现异常，那么函数load_565rle_image的返回值就会等于-1，这时候函数console_init_action就以文本的方式来显示第二个开机画面，即向编号为0的控制台（/dev/tty0）输出带“ANDROID” 文字静态logo

7. [ 4.019576] init:

8. [ 4.019583] failed to mount pstore pstore /sys/fs/pstore ret=-1 errnostr=No such file or directory

9. [ 4.049219] EXT4-fs (actc): mounted filesystem with ordered data mode. Opts: noauto_da_alloc

10.[ 4.070701] EXT4-fs (acte): mounted filesystem with ordered data mode. Opts: nodelalloc

11. ================正常打印，挂载文件系统，一些挂载出错，主要是原因是文件不存在

12. [ 6.397025] init: value=512misc info read type=0, size=32

13. [ 6.417399] init: failed to open /data/system/entropy.dat

14.========正常打印，打开/data/system/entropy.dat时出错，

15. [ 6.435154] healthd: wakealarm_init: timerfd_create failed

16.========正常打印，healthd进程创建timerfd_create时失败

17. [ 6.453868] binder: 1140:1140 transaction failed 29189, size 0-0

18.[ 6.497618] init: property 'sys.powerctl' doesn't exist while expanding '${sys.powerctl}'

19. [ 6.506132] init: powerctl: cannot expand '${sys.powerctl}'

27. 01-07 06:21:37.500 I/SurfaceFlinger( 1333): SurfaceFlinger's main thread ready to run. Initializing graphics H/W...

28.=======启动SurfaceFlinger服务：合成图像并显示到屏幕。启动该服务过程中会触发init启动一个bootanimation进程，其会开始启动动画显示，也就是我们看到的带“android”字样的启动动画

29. EGL_CONTEXT_PRIORITY_LEVEL_IMG ~~ used default

40.01-07 06:21:39.350 I/AudioFlinger( 1341): Using default 3000 mSec as standby time.

41. =======启动AudioFlinger服务：由mediaserver服务启动，是Android音频系统的两大服务之一，AudioFlinger向下访问AudioHardware，实现输出音频数据，控制音频参数。同时，AudioFlinger向上通过IAudioFinger接口提供服务
