【Android】-- adb shell 命令探索
ADB是什么,做android开发的没有不知道的。
window下运行cmd,输入adb help就会打印adb都能够做的事情,包括 adb push 。。adb pull 。。 adb devices adb install。。。 等等。。并且一搜一大把。
其中有一个命令叫做 adb shell,android是基于linux的,shell模式下linux的命令可是非常多的,android去掉了许多linux的命令,那么从这写命令里面又能够发现什么宝藏呢?寻宝之旅开启!!
首先linux的shell模式有许多命令,例如 ls cd mkdir su ps vim等等许多控制命令,这些在android上都是支持的。但是它是android的内核啊,应该有些特殊点的吧。
通过命令cd /system/bin 进入bin目录查看一下。

噢 my god 命令还是很多的嘛!
我们一般可以通过 命令 -h 来查看介绍,例如:
# am -h am -h usage: am [subcommand] [options] usage: am start [-D] [-W] [-P <FILE>] [--start-profiler <FILE>] [--R COUNT] [-S] <INTENT> am startservice <INTENT> am force-stop <PACKAGE> am kill <PACKAGE> am kill-all am broadcast <INTENT> am instrument [-r] [-e <NAME> <VALUE>] [-p <FILE>] [-w] [--no-window-animation] <COMPONENT> am profile [looper] start <PROCESS> <FILE> am profile [looper] stop [<PROCESS>] am dumpheap [flags] <PROCESS> <FILE> am set-debug-app [-w] [--persistent] <PACKAGE> am clear-debug-app am monitor [--gdb <port>] am screen-compat [on|off] <PACKAGE> am display-size [reset|MxN] am to-uri [INTENT] am to-intent-uri [INTENT] 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. am force-stop: force stop everything associated with <PACKAGE>. am kill: Kill all processes associated with <PACKAGE>. Only kills. processes that are safe to kill -- that is, will not impact the user experience. am kill-all: Kill all background processes. am broadcast: send a broadcast Intent. am instrument: start an Instrumentation. Typically this target <COMPONENT> is the form <TEST_PACKAGE>/<RUNNER_CLASS>. Options are: -r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT). Use with [-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 am screen-compat: control screen compatibility mode of <PACKAGE>. am display-size: override display size. am to-uri: print the given Intent specification as a URI. am to-intent-uri: print the given Intent specification as an intent: URI. <INTENT> specifications include these flags and arguments: [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>] [-c <CATEGORY> [-c <CATEGORY>] ...] [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...] [--esn <EXTRA_KEY> ...] [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...] [--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...] [--el <EXTRA_KEY> <EXTRA_LONG_VALUE> ...] [--eu <EXTRA_KEY> <EXTRA_URI_VALUE> ...] [--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]] [--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]] [-n <COMPONENT>] [-f <FLAGS>] [--grant-read-uri-permission] [--grant-write-uri-permission] [--debug-log-resolution] [--exclude-stopped-packages] [--include-stopped-packages] [--activity-brought-to-front] [--activity-clear-top] [--activity-clear-when-task-reset] [--activity-exclude-from-recents] [--activity-launched-from-history] [--activity-multiple-task] [--activity-no-animation] [--activity-no-history] [--activity-no-user-action] [--activity-previous-is-top] [--activity-reorder-to-front] [--activity-reset-task-if-needed] [--activity-single-top] [--activity-clear-task] [--activity-task-on-home] [--receiver-registered-only] [--receiver-replace-pending] [--selector] [<URI> | <PACKAGE> | <COMPONENT>] Error: Unknown command: -h
虽然-h没法识别,可还是打印出了参数的。
1、am命令是非常有用的一个命令,使用此命令可以启动 activity, services;发送 broadcast等等。
使用实例:如启动一个 Activity:
格式:adb shell am start -n 包名/包名+类名(-n 类名,-a action,-d date,-m MIME-TYPE,-c category,-e 扩展数据,等)。
实例1:C:\Users\Administrator>adb shell am start -n com.android.camera/.CameraStarting: Intent { cmp=com.android.camera/.Camera }
实例2:(带extra 的 intent)C:\Users\Administrator>adb shell am start -n com.android.camera/.Camera -e abc helloStarting: Intent { cmp=com.android.camera/.Camera (has extras) }其中 extra 的 key 为 abc ,value 为字串 "hello"
还可以发送命令模拟手机低电环境:
实例:adb shell am broadcast -a android.intent.action.BATTERY_CHANGED --ei "level" 3 --ei "scale" 100
2、getprop/watchprops
getprop列出系统的属性,前面十名字,后面是值
# getprop
getprop
[ro.secure]: [0]
[ro.allow.mock.location]: [1]
[ro.debuggable]: [1]
[persist.service.adb.enable]: [1]
[ro.kernel.qemu]: [1]
[ro.kernel.console]: [ttyS0]
[ro.kernel.android.checkjni]: [1]
[ro.kernel.android.qemud]: [ttyS1]
[ro.kernel.android.ndns]: [1]
[ro.factorytest]: [0]
[ro.serialno]: []
3、watchprosp动态监视这些属性的变化,比如我修改系统的语言为中文,就会打印出:
# watchprops
watchprops
1269420653 persist.sys.language = ‘zh‘
1269420653 persist.sys.language = ‘CN‘
4、 wipe <system|data|all>
wipe表示清除模拟器或者真机上的数据,比如你的模拟器用了很久,装了很多软件就可以用这个来清除
system表示清除 /system下的数据
data表述清除 /data 下的数据
