adbs路径:
build/tools/中发现了它——adbs!
adbs是一个用python写的命令行工具,利用了adb,addr2line, objdump这三个工具,大家看了这三个工具,可能就能猜到,adbs是用来分析应用程序尤其是与函数库相关的crash问题:)
具体的代码就不多看了,无外乎是一些运行环境的设定。
下面就来看一下如何使用它:
1. 设定好ANDROID_PRODUCT_OUT环境变量
ANDROID_PRODUCT_OUT="[your_path]/mydroid/out/target/product/generic",因为adbs需要使用到编译好的symbols,所以你需要编译整个android的source,得到与你调试环境一致的symbols文件
2. 直接运行adbs
adbs logcat
我特意准备了一个会crash的jni测试程序,得出的结果如下:
I/DEBUG ( 170): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
I/DEBUG ( 170): Build fingerprint: 'tmous/htc_pyramid/pyramid:2.3.4/GRJ22/125597.1:user/release-keys'
I/DEBUG ( 170): pid: 20715, tid: 20727 >>> [your product name] <<<
I/DEBUG ( 170): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr deadbaad
....
I/DEBUG ( 170): scr 80000010
I/DEBUG ( 170):

I/DEBUG ( 170): #03 (unknown) (unknown)

I/DEBUG ( 170):
这里明显可以看出adbs给出了有用的黑体部分的信息,即做了一些地址到具体程序函数名和行数的转换,方便我们定位问题。
为了给大家看得更清楚,下面是单纯使用logcat看到的crash信息:

am start -a action android:name="android.intent.action.VIEW" -d 输入的数据 -n package="com.android.gallery"/activity android:name="com.android.camera.MovieView
也就是 am -a "action" -d data -n "package/activity"
例如:
am start -a android.intent.action.VIEW -d /mnt/video/aaa.mkv -n

am start: start an Activity. Options are:
-D: enable debugging
-W: wait for launch to complete
--start-profiler <FILE>: start profiler and send results to <FILE>
-P <FILE>: like above, but profiling stops when app goes idle
-R: repeat the activity launch <COUNT> times. Prior to each repeat,
the top activity will be finished.
-S: force stop the target app before starting the activity
am startservice: start a Service.

[-e perf true] to generate raw output for performance measurements.
-e <NAME> <VALUE>: set argument <NAME> to <VALUE>. For test runners a
common form is [-e <testrunner_flag> <value>[,<value>...]].
-p <FILE>: write profiling data to <FILE>
-w: wait for instrumentation to finish before returning. Required for
test runners.
--no-window-animation: turn off window animations will running.
am profile: start and stop profiler on a process.
am dumpheap: dump the heap of a process. Options are:
-n: dump native heap instead of managed heap
am set-debug-app: set application <PACKAGE> to debug. Options are:
-w: wait for debugger when application starts
--persistent: retain this value
am clear-debug-app: clear the previously set-debug-app.
am monitor: start monitoring for crashes or ANRs.
--gdb: start gdbserv on the given port at crash/ANR
